Here’s how you do it:

Find what works for them in terms of discounts/offers/ads, and take cues.
Incorporate the above into your customer acquisition strategy to lower cost per conversion and CAC.
The goal is simple—reduce customer acquisition costs by keeping production & storage costs low.
Here’s how you drive lower CAC:
Sync up product images, descriptions, recommendations, and social proof to nudge the shopper to buy.

Here’s a quick checklist of to-dos:
Keep a close eye on the evolving preferences and behaviors of your target market.
Add details like region, demographic, occupation, goals, motivations, lifestyle preferences, challenges, etc.

For example, if your skincare products are meant for women over 35, Gen Alpha lingo won’t work.
Here’s why—77% of B2C marketers agree that the right kind of content helps increase ROI by 24%.
That includes the subject lines, product recommendations, discounts, and birthday celebrations.
Retaining existing customers costs 6 to 7X less than acquiring new customers—but almost 70% of all carts are abandoned.
Thus, one of the biggest ways to reduce eCommerce acquisition costs is by implementing a cart abandonment strategy.
Here’s what you need to keep in mind:
Assess what additional costs are necessary and offer a cost split-up in the cart itself—or create an attractive free shipping threshold.

Customers drop off from your site for many reasons—knowing where and why is critical.
Here are a few tested measures we’ve applied to deal with drop-offs:
Look for issues like poor search that does not show up alternatives or related categories.
ScreamingFrog works well.
Heatmaps can also help identify form fields that cause friction.
Use dropdowns, a horizontal content format, bullet points, and "load more" features.
Make the product name, price/discount, and short one-line descriptor non-negotiable.
Find out what’s not working—is it the CTA, the language, the offer, or when it’s being shown?

90% of customers are likely to buy from brands that clearly show they know personal engagement preferences & buying behavior.

For example, one member might want early access to product launches but another might expect to be told about a flash deal early.

According to statistics, 92% of shoppers can trustingly rely on a brand people they know have referred.
Here’s how you can create a referral program, with low-cost customer acquisition and retention:
These can be effective at getting more customers interested in the incentives.
Create a quick three-question survey that asks them about the ease, the experience, and the incentives—you can highlight snippets of these to market the program.
The best way to do this is through email as a medium marking them both declaring discounts, offering recommendations, etc.
Ensure that the referrer and the person get their rewards simultaneously—ensure to update them on the points, discounts, or cash back they’ve earned.
Here’s a fact you may not know:
Only 21% of shoppers start their research right before they buy.
So, to draw them and then retain them, you’ll have to develop a robust pricing strategy:
Apply the central fixation bias to sell products that aren’t cheap or too expensive and hence unattractive.
Offer choices like buying more of the same product and adding relevant upsells to increase the cart value.
Bring out product differentiation including ingredients, make, and technology to make the price seem convincing.
Research says charm pricing can bring in 24% more revenue versus other pricing counterparts.
When you ‘smart bundle’ fast-selling products and slow-selling products to give it away at an attractive (discounted price), it’s a win-win.
Here are a few tips that can help you move towards lowering your eCommerce customer acquisition cost:
This can instantly make the shopper perceive the "bundle" as superior to independent purchases.
For example, bundling a tongue cleaner with a toothpaste and toothbrush is way more relevant than bundling with a torch.
When you place a smart bundle under the “bestsellers” section and give it this label, potential customers experience greater trust & confidence.
This makes shoppers more sensitive to the price difference—and hence, the savings too.
One eCommerce brand that’s known for its super-valuable bundles is Vanity Planet.
This can especially be more effective right before peak holiday season.
Essentially, there will be a number of products in your bundle, but you won’t be able to buy them independently.

According to a study a while ago, 61% shoppers liked the fact they received promotional emails weekly from brands.
However, what’s not covered in the statistic is that shoppers also anticipate quality in emails and make buying decisions based on that.
Consider the following:
Is it to nudge customers towards a new product launch or reminding them to checkout with products left back in the cart?
Ensure the copy is welcoming and you’re using supporting factors like social proof, how many people have already bought from a particular product range etc.
For example, if you want them to checkout, you may want to declare a limited-time discount.
If you’re nudging customers to look at certain products, you might as well introduce alternate suggestions saying “try these instead".
According to some crucial customer engagement research 88% say that experience matters as much as quality of products—when you offer drip email content that personalizes and nurtures, customers want to buy from you.
Build on the story—if you’ve been sending bestseller recommendations, take it to the next level with a discount they can act upon.
One brand that’s known to create inspiring drip emails is Patagonia.
Here’s an example of one of their newsletter sign-up welcome emails.

While traditionally a lot of focus has been placed on what products you offer for upselling and cross-selling, through our experiments we’ve noticed that the HOW is also equally relevant.
There’s research out there already that effective upselling and cross-selling can increase up to 30% of a business’s revenue.
Here are steps in the right direction if you’ve been wanting to reduce your eCommerce customer acquisition cost:
The point is to have customers not experience choice paralysis and instead add more products to their carts.
For example, SMS has shown to be a big grosser in terms of customers engaging with upsell & cross-sell content sent by businesses.
This can have an immediate impact on how confident a customer feels about the suggestions being made to them.
For example, if you’re promoting a better battery, say something like “lasts 5 times longer than…” – context helps customers convert faster.
Landing pages are known to be 123% more effective in comparison to other forms of sign-up.
Businesses that happen to have 10-12 pages end up enjoying 55% more leads.
Put simply, effective landing pages help potential customers to move towards a purchase.
So, when designing landing pages, here are some key factors you’ll need to consider:
Note how Marley Spoon’s landing page has clean layouts, self-explanatory images, and no-nonsense copy.
Further, note how the mobile version uses a sticky menu that acts as a progress bar.

To improve CLV, customer experience needs to improve dramatically.
And not all of it depends on live chat or support numbers—when shoppers experience greater control through information & clarity, they’re more likely to buy from you.
Here are a few ways you could consider:
Email automation that covers a wide range of email communication can be helpful.
After all, they need to know where to look for answers.
This is the reason some thriving eCommerce brands have closed discussion groups on Facebook.

A low CAC alone doesn't guarantee success—despite having low CAC, a low AOV can tank your ROI.

CPA or Cost per Acquisition measures how much it costs to get someone interested in your product or service.
CPA is both a traditional and eCommerce metric traditionally used in advertising; however, CAC is all about the net cost incurred.
Meanwhile, LTV is all about the spending potential of a customer.

If you spend more to acquire customers than they're worth in the long run, your overall profitability suffers.

So along with attempting to reduce CAC, it might be worthwhile to increase CLV - or the total amount you earn from a customer over time.
Here are five steps you can take to increase CLV while making your CAC-reducing efforts:
1. Double down on customers from top locations
2. Find your top categories/products
3. Track your top traffic sources
4. Ensure you’re selling to the RIGHT audience
5. Build a solid cart abandonment strategy
6. Optimize every step in your conversion funnel
7. Design a loyalty program for long-term conversions
8. Start a “sticky” referral program
9. Get smarter with pricing
10. Apply smart bundling tactics
11. Make your drip emails inspiring
12. Make your upsells & cross-sells compelling
13. Create distraction-free landing pages
14. Improve self help across touchpoints
15. Make it easy for shoppers to share feedback

17. Collaborate with other brands (with similar audiences)
18. Create a niche
19. Monitor your retargeting campaigns closely
20. Bring in a “nurturing” content strategy
21. Avoid common A/B testing mistakes
