153 A/B Testing Ideas for eCommerce (Homepage, PDP, Cart, Checkout)

While the whole of eCommerce speaks of conversions, so much of that success lies in the powers of A/B testing.

According to a Speero report, 40% of CRO testers make archives out of their past tests, so that they can learn from them in the future.

Exactly why we thought, why not create a comprehensive list of variants we've tested, learnt from and helped clients with to earn more conversions.

With this one, you have your entire funnel covered PLUS a section on emails—here's a quick shortcut to the main sections:

eCommerce A/B Testing Elements To Boost Conversions

Ideas for Stage One: Homepage

1. (A) Mega menu / (B) Horizontal menu

In our experience of using AB testing ideas, we’ve noticed mega menus work with businesses that have countless categories and product offerings. 

Horizontal menus work better for businesses with limited products and those that prioritize the mobile experience

2. (A) Sticky navigation menu / (B) Non-sticky menu

At the top of the funnel, when a shopper is trying to get to know your brand in more detail, a sticky menu might just work better—it offers more navigational control across the homepage and beyond. 

3. (A)  Labels for primary categories / ( B) Labels for sub-categories

Anchor & Crew highlights labels for their main categories—though the more usual practice for brands is to label their dropdown subcategories. 

anchor & crew labels relevant categories in the primary navigation to attract website visitors

4.  (A) Rotating carousel /  (B) Single hero image

Two bits from A/B testing eCommerce experience: even if you’re using a rotating carousel, make sure you offer manual control through visible previous-next buttons—if you choose to keep it on auto-rotate, let it be slow enough for shoppers to register what’s on each slide. 

5. (A) Copy against the image / (B) Copy & image in separate sections

eCommerce brand Morphe Cosmetics places their copy (unobtrusively) against the hero image.

Morphe Cosmetics features copy over the hero header image in a distinct yet uninterfering way

Larq, on the other hand, splits the hero banner between plain background for copy and then image for their eCommerce A/B testing.

Larq uses a plain background to display the headline while using an image in a separate frame alongside

6. (A) Short headline / (B) Longer headline

Fitbit, for example, keeps it super short as part of their eCommerce testing strategy. 

Fitbit features a short but relevant headline in their hero header space

Beardbrand, on the other hand, keeps it simple yet longer in this eCommerce A/B testing idea.

Beardbrand features a hero headline that immediately informs the shopper about what the brand does and when it was established

7.  (A) Headline as description  / (B) Headline as question

While a description typically sets more context for the shopper, a question pushes them to think about the problem at hand that has brought them to the homepage.  

8. (A) Brand-specific headline / (B) Product-specific headline

To enhance your eCommerce AB testing strategy, you could use the latter during peak season sales.

9. (A) Hero banner copy a mix of features & benefits / (B) Benefits-based hero banner copy

10. (A) The benefits come in bullets / (B) The benefits come in a paragraph

11. (A) Hero headline with microcopy / (B) Hero headline without microcopy

When experimenting with eCommerce A/B testing ideas, remember: microcopy takes an argument (made in the headline, let’s say) further—it can talk about value-add, a benefit, a limited time offer etc. 

12. Test the above-the-fold CTA button (for different shapes, color, texts, positions etc.)

13. (A) Feature single CTA on the hero banner / (B) Feature multiple CTAs 

Crossrope, for example, currently features two CTAs on their homepage hero space—this is one of the underrated eCommerce A/B testing ideas that can help you segment your audiences better:

Crossrope features a secondary CTA in their hero header to make it easy for new shoppers to explore the storefront

14. (A) All prominent CTAs / (B) Some CTAs more prominent than others

To make certain CTAs less prominent, you might want to skip not color-blocking them—when you’re doing AB split for eCommerce, color-blocking transactional CTAs is usually a good idea. 

15. (A) Only button CTAs / (B) Button CTAs + visual cues

Ikea, for example, features a range of CTAs on their homepage (notice how the visual cues are also on point) as an eCommerce testing strategy:

Ikea features a range of CTA buttons on their homepage

16. (A) Make the header a sign-up prompt / (B) Feature a seasonal sale discount

Which of these eCommerce AB testing ideas you choose will primarily depend on your conversion goals. 

17. (A) Product quiz in the primary navigation / (B) Sticky “product finder” button

Adore Beauty features a sticky product finder button as one of their A/B testing ideas—making it easy for on-the-go folks to explore more quickly. 

Adore Beauty displays a sticky product finder button that opens up into a quiz when clicked

18. (A) Featuring more copy throughout / (B) Featuring more visuals

Beardbrand clearly features more copy in this example of A/B testing for eCommmerce.

beardbrand features copy on their homepage that informs shoppers about the brand's values and beliefs

Room & Board’s homepage, on the other hand, is clearly more visual-led in this version from their A/B test ideas:

Room & Board has a homepage design that prioritizes visuals over text

19. (A) Feature more product visuals / (B) Feature more people visuals

Which of these A/B test ideas will work has to do with what kind of business you are—for example, if you sell jewelry, bold “people” photos will work better than if you’re into selling outdoor cooking equipment. 

20. (A) Showcase a brand video / (B) Feature a bestseller video

21. (A) Feature hero product images / (B) Feature hero product GIFs

While technically both are image formats, GIFs when used well, convey more information and help set greater context for the shopper—while conducting the AB split for eCommerce consider your site loading speed to choose the right variant. 

22. (A) Header with founder’s message / (B) Header with brand values 

Try out the latter in the form of graphic icons with text callouts.

23. (A) Hero image with social proof badge / (B) Hero image with press mentions

Huel, for example, showcases a Trustpilot badge on their hero space as part of their a/b testing for eCommerce ideas:

Huel showcases a trustpilot badge on their homepage header space

24. Test between “free shipping” & “free mystery gift” callouts on the notification bar

25. (A) Feature a link to customer reviews / (B) Feature customer review snippets

Ritual is an eCommerce brand that seems to have done both in their eCommerce AB testing—reviews highlighted as quotes and video links too!

Ritual features a range of reviews both in quotes and videos

26. (A) Highlight a customer review snippet / (B) Highlight reviews AND press mentions

27. (A) Create a section with press mentions / (B) Create a section with purchase impact data

Unlike many other brands, Unconditional chooses to throw light on how a purchase creates impact—this is a great TOFu A/B testing eCommerce idea:

Unconditional reserves a section to talk about the impact each purchase creates

28. (A) “About” section with link to about us page / (B) Brand promises called out through icons

29. (A) Feature a discounted categories section / (B) Feature a “deal of the week” section 

Burrow cites categories along with their associated discounts in their eCommerce a/b testing efforts. 

Burrow features their categories by highlighting the discount each one carries

On the other hand, Ikea highlights various categories as "deals of the week".

Ikea brings attention to their categories by featuring deals of the week

30. (A) Show “shop by categories” / (B) Show “shop by brands” with clickable logos

Larger third party aggregator brands can do a third variant combining both in their eCommerce testing strategy. 

31. (A) Feature BNPL options in the footer / (B) Highlight popular payment methods 

eCommerce brand Unconditional does the latter in their A/B testing in eCommerce. 

We’ve seen that highlighting BNPL options work really well if your primary target audience is the younger crowd—after all, 56% of millennials claim to use BNPL options widely. 

Unconditional features a number of popular payment methods below their footer section

32. (A) Section on loyalty program savings / (B) Section on regular flash sales

33. (A) Social buttons on the footer / (B) Social buttons on the upper navigation panel

Since social handle visits and shares are important micro-conversions, you need to include them in your AB split testing for eCommerce. 

34. (A) Social wall featuring influencers / (B) Social wall featuring real customers

35. (A) Randomly picked images for the social wall / (B) Strategic, contextual images

We love how cleverly Crossrope brings their social wall alive on the homepage—they feature customer cases that have a marked visual difference in this eCommerce A/B testing idea. 

Crossrope features handpicked images on their social wall that speak of customer success

36. (A) Sections with links to brand/values / (B) Section with links to featured blogs

37. (A) Feature tiles of latest blogs / (B) Feature a “learn” section in the primary navigation 

38. (A) Show email signup alert above/below primary navigation / (B) On the footer

39. (A) A short homepage / (B) A longer version

Remember: even if you want a short homepage as part of your A/B testing ideas, you’ll need to balance transactional and non-transactional elements in it.

Key Takeaways for Homepage eCommerce AB Testing

No matter which variants you choose and in what order, for your homepage A/B testing to be successful:

Incorporate a sticky feedback button on the side—this can help you gather more data on CX

Keep a track of average time on page & dwell time—both are crucial because when it comes to organic traffic, the homepage is often the landing page

Ideas for Stage Two: Category Page

40. (A) Position the filter vertically on the left / (B) Horizontally in the center at the top

41. (A) Sub-categories appear as plain text / (B) Sub-categories highlighted through buttons 

Nordstrom features links to sub-categories to a/b split for eCommerce:

nordstrom shows sub-categories in the form of linked and underlined text

ASOS, on the other hand, features button blocks. 

ASOS highlights sub-categories through clickable buttons

42. (A) An above-the-fold banner shows a sale/discount / (B) Banner talks about the category

Fabkids features the first idea in their AB split testing for eCommerce: 

Fabkids drives their vip member offer through their category page above the fold banner

100% Pure calls attention to the category you’re visiting. If you want to announce a special discount on a specific category, the banner space is ideal for drawing attention. 

100% pure highlights the quality of products through their category page banner

43. (A) Primary CTA featured beneath the product image / (B) Product image with NO CTA

Mejuri does not use add to cart buttons on their category page—this can often compel shoppers to go into individual product pages to know more.

Mejuri does not feature primary CTA button for their listed products across category pages

44.  (A) Image with wishlisting icon / (B) Image with no wishlisting icon

45. (A) Feature wishlisting icon on the image / (B) Icon next to the product details

eCommerce AB testing on such subtle nuances can be helpful for a brand to get a deeper sense of what’s driving better UX—in this case, whichever variant receives more wishlisting needs to be incorporated to fight cart abandonment

46. (A) Use only price for sorting / (B) Also use additional features (like recommended, newest/oldest, customer rating etc.)

47. (A) Feature 5-starred suggestions in the top row / (B) Feature 5-starred suggestions with discount

48. (A) Use average star ratings as a number / (B) Mention no. of reviews & make it clickable 

In their AB split for eCommerce, Sephora features the average rating through the colored stars, plus the number of reviews made. 

Sephora features the exact average star ratings for every product in their category pages

49. (A) Make rating & no. of reviews constantly viewable / (B) Viewable only on hover

The latter can potentially pique the shopper’s interest—and hovering to see the review can become one step in the overall category page engagement. (Beardbrand does it as one of their eCommerce AB testing ideas.)

50. (A) Offer a “quick view” option / (B) Use a “quick add” option

51. (A) Sale/Special Price label & reduced price / (B) Sale/Special Price label & price anchoring 

52. (A) Use a “Selling Fast” label / (B) Use an “X pieces left only!” label

When you’re AB split testing for eCommerce, pay attention to how options with specified quantities and timeframes perform—typically, stating it creates more urgency!

53. (A) Feature new price marked in bold color / (B) Old price grayed out & struck through 

Nordstrom features both new and old prices for shopper satisfaction in their a/b testing eCommerce strategy—the new prices show up in a strong, bold color. 

Nordstrom features both the discounted price and the percentage drop in bold colors

54. (A) Show old price grayed out & new price in different color / (B) Also show discount savings 

55. (A) Describe size range in the image description / (B) Use “available in various sizes” on hover 

Zalando uses the second idea in their category page a/b test ideas—and it’s helpful for shoppers scrolling through by leading them into the respective product pages

Zalando features a callout that alerts shoppers about the different sizes of a product

56. (A) Use the “Sold Out” label / (B) Use “Notify Me” as a label

57. (A) ColorS can be viewed with < > buttons / (B) colors displayed with “+X colors available” 

58. (A) All color buttons displayed irrespective of availability / (B) Unavailable colors are struck off

59. (A) Sticky email sign-up discount alert on the left panel / (B) “X from so-and-so place bought <name of the product” & image

Built Athletics uses the second idea in their eCommerce AB testing strategy—the social proof features a product shown on the page you’re at, inciting curiosity. 

Built Athletics features "customer X from Y brought product Z" prompts on their category pages

60. (A) Use a descriptive callout for the product on the image / (B) Image with no callout

Huel, for example, makes sure each of their products carries a label that’s unique—this becomes an easy way to absorb information for shoppers who are speeding through. 

huel highlights a relevant label for every product to draw attention from those quickly scrolling

61. (A) One line descriptor beneath the product image & product name / (B) Only product name

While optimizing conversion rates through a/b testing and user experience, we’ve noticed that the use of descriptors can sometimes appeal to instant purchase decisions, especially that of impulse buyers

62. (A) Recommendation section of lesser-priced accessories / (B) Section on new releases

63. (A) Show total number of page results at the top / (B) Number of page results split by sub-categories

Women’s Best features the number a shopper can expect in sub-category page results as well—this is one of those A/B test ideas that can ease navigation & reduce scrolling fatigue

Women's Best shows how many results each sub-category page carries

64. (A) Show “load more” at the bottom of the page / (B) Flank “load more” by how many results a shopper is seeing currently

65. (A) Let shoppers choose how many results to see per page / (B) Shoppers don’t have this choice

How much control you give to the shopper at the category page stage, can influence how deeply they explore your product pages—if it’s too many results, the overwhelm can make them easily drop off. 

66. (A) “Build Your Bundle” appears in the primary navigation / (B): Every product carries an “Add to Bundle” CTA

Pipcorn ends up using both ideas in combination in their eCommerce testing strategy, which means you could too! (Here's some bundling examples for inspiration.)

You must also check out: Why Is Your Conversion Rate Low: Possible Causes + Solutions

Pipcorn features a secondary CTA that lets shoppers add that product to their bundle

67. (A) Use “buy more get $x off” image labels / (B) Use BOGO image labels

Notice how Fashion Nova hypes up BOGO labels in their a/b test for eCommerce personalization:

fashion nova highlights their bogo free offers on category pages

On the other hand, Chubbies urges to buy more for an additional discount in their A/B testing strategy.

chubbies highlights the label of buy 2 and save $10

68. (A) Use the notification bar to show highlights like free shipping / (B) Feature highlights in the section above the footer

From working with 500+ clients across the world, we’ve noticed that the first idea works better for more immediate offerings such as flash deals, a sitewide discount etc. 

The second idea is more suited for values the brand stands by—for example, if the brand is sustainable and 100% natural, this information can come right above the footer in the form of icons. 

69. (A) Feature “Bestsellers” in the top row / (B) Feature “Limited Edition” products

Some brands combine the two in their A/B testing solutions for eCommerce to enable greater product discovery

70. (A) Show “Quick Add” prompt before size selection / (B) Show size and “Quick Add” feature prompts together

In the following examples, notice how Fashion Nova features a quick add and when a shopper clicks on it, the size options open up. 

Fashion Nova quick add a/b testing for eCommerce idea

Gymshark, on the other hand, shows both as soon as a shopper hovers over the product image. 

Gymshark quick add option a/b testing eCommerce idea

71. (A) “Flash Sale” products featured alongside regular discounts / (B) Only regular discounts are promoted

Golde is one brand that clearly labels some of their products as being under “flash sale”—this induces urgency and can inspire shoppers to explore those products further. 

Golde features a flash sale label for select products on their category pages

Key Takeaways for Category Page AB Testing eCommerce Ideas

Filtering & sorting experiments will be most necessary for you to improve navigation on these pages

Bestsellers & items on sale need more space in the first few scrolls

Include “quick view” info button to influence shoppers faster

Ideas for Stage Three: Product Page

72. (A) Product name gets more attention / (B) Payment methods are more prominent

Here’s how boldly Morphe features its product names as part of their product page test ideas:

Morphe makes its product names come across as extra bold on their product pages

In contrast we noticed how Huda Beauty also highlights the payment terms. 

Huda Beauty highlights payment options more than the product name

73. (A)  A short product description above the CTA / Variant B: Display only key features

Here’s how it looks in real time—The Ordinary lays down the key features in their eCommerce testing strategy:

The Ordinary highlights the key features of a product right above the primary CTA on the product page

Dripkit describes the product in a short snippet in their product page a/b testing.

Dripkit features short prodct descriptions on their product pages

Quick tip: Which format you use will depend heavily on the nature of your target audience—if your products help them solve problems (and not just add to life, like say, coffee does), then technical specifications can become crucial. 

74. (A) Product description above the CTA / (B) Product description below the CTA

75. (A) ingredients listed in a block of text / (B) A link is provided to a separate page 

FAE Beauty is a brand that goes in-depth in explaining its ingredients—hence they do so in a separate page for every product. 

This is the best approach if you want to state your AB testing solutions for eCommerce to improve the brand transparency you project. 

FAE Beauty features a separate page for product ingredients

76. (A) Product description in a horizontal format right above the CTA / (B) Product description in an expandable-collapsible vertical format under the first fold

77. (A) Describe how & where the product is made / (B) Describe the results from a real customer research

The similarity between the two instances is that both create a sense of authority that shoppers derive confidence from—though the second instance works more like social proof, especially when a brand sources the results from real-time research. 

Here’s an example from Golde's product page testing ideas:

Golde features real information from customer surveys on their product pages

78. (A) Image gallery in the first fold followed by CTA / (B) Keep the image gallery to the left

79. (A) Before-after buttons around the image gallery / (B) Images are laid out in thumbnail tiles right beneath the gallery

Skullcandy makes their image gallery come alive on the right side of the product page—the “next” button is the main feature in this A/B testing in eCommerce idea. 

Skullcandy features previous and next buttons to show product images outside of a conventional gallery format

Away, on the other hand, takes the more usual approach of keeping the image gallery to the left—and maintains thumbnail tiles for a quick overall view of the product. 

Away features all the image thumbnails on the top of the main product image

80. (A) A 360° degree gallery view / (B) One product image carries the most important labels (features, benefits, specifics)

From experience, we know that for products that are fairly simple, you can use the second approach—while for those that feature more parts or technical aspects, a 360° view can generate deeper trust. 

The Candi Factory, which creates breathable underwear, always labels their products in their eCommerce AB testing:

The Candi Factory labels their hero product image instead of writing elaborate descriptions

81. (A) The primary visual is a video / (B) The primary visual is an image

Primary visual = the image that’s on display when the shopper first lands up on your product page. 

82. (A) Place a GIF in the photo gallery / (B) Place a video right beneath the first fold

83. (A) The image gallery carries a zoom option / (B) The images are distinctly large (compared to the description section)

Luxy Hair, for example, makes use of bold visuals to do away with the need for a zoom option in some of their A/B testing ideas. 

Luxy Hair shows large and bold images to do away with the zoom feature

84. (A) Feature an unboxing video / (B) Use a section to show what’s in the package

For several reasons, including needing to reduce page loading speed and marketing spends, businesses look for alternatives to an unboxing video. 

The reason we love Bond Touch is because they’ve figured a middle ground—they just use thumbnail images of the different parts within a package. 

Bond Touch offers images and names of the parts of a product package

85. (A) Primary CTA first prompts to “select a size” & then changes to “add to cart” / (B) Primary static “add to cart” CTA 

Doing what Crossrope does can mean more intuitive UX—because it might not occur to shoppers that they should select a size first.

So if they add to cart and then are told “please select a size”, it just adds to the overall friction. 

Crossrope features a primary CTA that says select a size before a shopper picks a size and then changes to add to cart

86. (A) Features a secondary CTA of a popular payment method / (B) Features a secondary CTA  with a wishlisting option

87. (A) Secondary CTA allows shoppers to ask a question / (B) Secondary CTA that enables wishlisting

Hyphen Sleep calls a shopper’s attention to reaching out for support through a secondary CTA in their A/B split testing for eCommerce. 

Many shoppers who’ve found their way into the product page are intent on buying, and for a high investment product, it’s likely they would want to ask some questions before they even wishlist it. 

Hyphen Sleep features a seconary CTA on their product pages that allows shoppers to ask a question

88. (A) Secondary CTA features a special VIP price / (B) VIP membership benefits cited above the primary CTA (as a link)

Quick Tip: A secondary CTA featuring a special VIP price makes sense only when you don’t have a ton of other messages or labels vying for the shopper’s attention. For example, if you’re running a special price on the product, avoid using a secondary CTA like this because it can become overwhelming. 

In the following example from Fabkids, it’s clear that the brand is promoting a special price for members, and the whole above-the-fold section reflects this. 

fabkids displays a secondary vip add to cart CTA and pulls attention to a special price

89. (A) Feature color swatches over the primary CTA / (B) Feature a separate section of available colors below the fold

While featuring color swatches is the usual practice, some brands like Tanner Goods choose to highlight a color in the main product section and feature the rest in a section below—if you’re trying to convey quality and differentiation in your products, this could make for a more relevant eCommerce A/B testing idea:

tanner goods displays differently colored products of the same kind in a section separate from the image gallery

90. (A) Feature a size finder / (B) Feature a size chart

At the “desire” stage of the funnel, relevant engagement can inspire shoppers to actually make a purchase—a size finder or a size quiz can engage and personalize more than just a size chart. 

91. (A) The cart icon shows an updated number when a product is added / (B) The CTA click takes shoppers to a separate cart page

92. (A) Feature the gift wrap option  as a checkbox / (B) Feature a list showing the gift wrap options available 

Bonbonbon chooses to feature their gift wrap options as check boxes in their product page a/b testing:

93. (A) Customer review callout section right below the first fold / (B) Feature the usual product description section 

Adore Beauty calls out their “most helpful positive” review just below the first fold in their AB split testing for eCommerce—this can be helpful in creating greater confidence in the product. 

adore beauty highlights the most positive review for a product on that product page

94. (A) Highlight a customer review above the primary CTA / (B) Highlight a badge of quality above the primary CTA

Here’s how Overstock highlights a badge of quality above the primary CTA in this A/B testing eCommerce experiment: 

95. (A) Membership savings highlight above the primary CTA / (B) Gift card offer above the primary CTA 

Bed Bath & Beyond uses the second idea on its product pages

Bed Bath & Beyond features a gift card offer over the primary CTA

96. (A) Social media wall with the descriptor “Follow Us” / (B) Social wall descriptor reads “See It In Real Life”

If you’re a fairly established brand with other sub-brands people follow, then “follow us” may fetch better results in the A/B testing eCommerce results.

However if you’re a brand that’s still small and trying to win confidence, “see it in real life” can make more sense. 

97. (A)  Free shipping/X-day returns as link-based line items / (B) A content block that offers a “guarantee”

Solo Stove calls out their free shipping and returns information through a “worry free guarantee” label—this can instantly draw more attention. 

FAE Beauty features free shipping & returns as a linked line item:

98. (A) Upsell a related accessory / (B) Offer a similar product recommendation

99. (A) Highlight the background info about the product / (B) Highlight the brand differentiators 

Skullcandy creates context on how, where and why a product is made.

Skullcandy product information a/b testing idea

Lush, on the other hand, highlights their brand differentiators in their product page a/b testing.

Lush highlights brand differentiators for a/b testing in eCommerce

100. (A) Upsell through a CTA button / (B) Make a related product recommendation

Notice how Tanner Goods ups the price through a CTA for those who choose to opt for a monogram—a clever strategy to incorporate in your A/B test ideas: 

Tanner Goods lets shoppers add a monogram through a separate CTA

101. (A) Feature multiple variably priced recommendations / (B) Feature recommendations with the same price as the main product

102. (A) All recommendations being products on sale / (B) Feature just one recommendation on sale

Testing both will help you understand shopper behavior—and in turn inform whether you should test a third alternative with a half-and-half approach where, let's say, you put two recommended products under sale and two others under their original price. 

‍103. (A) Feature “Write a Review” button / (B) Feature a “Review & Earn” button

104. (A) Offer a customization field on the product page itself / (B) Feature a secondary customization CTA leading to a sub-page 

Baublebar sticks with the first idea in their A/B testing in eCommerce. 

baublebar features a separate field to let shoppers key in their name customization

105. (A) Display a product comparison table featuring similar products & prices / (B) Feature a comparison table with a some discounted products

Notice how Sephora features one product in the comparison table with a significantly different price. 

Sephora lets shoppers compare multiple products of the same kind

106. (A) Features a sticky feedback button / (B) Clickable link is displayed at the end of the page 

107. Test between a short product page variant & a longer one 

For either, you’ll have to determine which sections to keep and which ones can go. 

Here are a few successful ways in which we’ve shortened product pages for customers:

- Offered a link to the product video on Youtube (vs. dedicating a section of the page to the video)

- Created a separate page for product ingredients (so that a “read more” button can take them there after they’ve read the basics on the page)

- Fashioned the product description section like an FAQ

Key Takeaways for Product Page A/B Testing in eCommerce

Carry out most of your A/B testing ideas around the first fold 

Experiment with how & where you feature your microcopy

Give a lot of importance on testing product description layouts 

Ideas for Stage 4: Cart Page

108. (A) Feature a wishlisting option / (B) Don’t feature a wishlisting option

109. (A) A “free shipping threshold” message / (B) A “free shipping for loyalty members” message  

Lush makes use of the first idea in their eCommerce testing strategy—and this is how it looks:

sephora displays how much more the shopper has to spend to get free shipping in the mini cart

110. (A) Free shipping threshold progress bar / (B) Store credit threshold progress bar 

Larq, for example, makes use of a store credit threshold progress bar as part of the eCommerce AB testing ideas:

larq features a store credit threshold progress bar in the mini cart

111. (A) Feature a store credit threshold progress bar / (B) Feature a free gift threshold bar

112. (A) Feature a choice of free samples / (B) Feature an applicable discount code 

113. (A) Feature “under $x” product recommendations / (B) Feature complementary products

114. (A) Show one product recommendation at a time / (B) List the recommendations in a vertical/horizontal format

Golde ensures a shopper has access to multiple product recommendations—but can focus on each one thanks to previous-next arrow buttons. 

golde features one product recommendation at a time in their mini cart

115. (A) Call your recommendation section “Recommended For You” / (B) Call it “Things We Know You’ll Love”

While the first puts the brand in a place of authority, the second focuses on shopper preference—and there can be a marked difference of conversions between the two. 

116. (A) Promo code is automatically applied / (B) Provide an open field with a list of “featured offers” 

117. (A) Feature standard “apply discount code” field / (B) Feature a special applicable discount 

Death Wish Coffee, for example, reserves a special discount for military first responders, government employees and teachers in this eCommerce A/B testing idea. 

Death Wish Coffee offers discount to military, first responders, government employees and teachers in their mini cart page

118. (A) Feature “free shipping & expedited shipping” callouts / (B) Feature “delivery & pickup” callouts

119. (A) Highlight “sale savings” amplifying the new price / (B) Feature the old & new prices w/o a callout

How to analyze your A/B tests

1. Track the right metrics

When you're trying to make sense of your A/B tests, it's important that you track the right metrics—here are a few we've found to be super relevant:

- Bounce Rate (the % of visitors who hop off your storefront after viewing just one page)

- Scroll Depth (how far your shoppers scroll once they land on your site)

- Abandonment Rate (the % of tasks shoppers open but don't conclude—for example, adding to cart but not finishing the purchase)

- Conversion Rate (the % of shoppers who complete a desired action—it can further be divided into micro-conversions and macro conversions)

2. Divide your audience into segments

You can factor in various critical elements to do the segmentation—these factors include demographic, motivational, behavioral, attitudinal and preferential amongst others. Factoring in segments can help you test more deeply and analyze in a more granular way.

3. Monitor behavior analysis tools closely

There's a reason why behavior analysis tools such as heatmaps and visitor recordings help in breaking down results from A/B tests—for one, they can help you notice which pages on your site are getting more traction. They're also instrumental in indicating what's happening to visitor behavior across the conversion funnel.

What are the most important metrics for eCommerce A/B testing?

✔ Conversion Rate: This metric calculates the percentage of shoppers who complete a desired action (for example, adding to cart)

✔ Bounce Rate: This metric calculates the percentage of shoppers who land on a page but do not proceed to look at other pages.

✔ Clickthrough Rate: This calculates the percentage of shoppers who clicked on a said link versus the percentage that saw the link but didn't click it (in eCommerce, this metric helps businesses gauge the effectiveness of both transactional and non-transactional links.)

A/B testing or not, 98% of visitors who visit an eCommerce site still drop off without buying anything.
