Question 1

What is customer retention in e-commerce, and how do you calculate it?

Accepted Answer

Retention is the share of customers who come back to buy again after a first purchase within a given window. It's the opposite of churn — the share of customers who vanish after their first order. Working out your retention rate is straightforward.

Question 2

How much does it cost to retain a customer versus acquiring a new one?

Accepted Answer

Winning a new customer costs far more than keeping one you already have: the industry benchmark puts it at 5 to 25 times more. It's the figure that should rebalance every marketing plan. The reason is CAC — customer acquisition cost. Every new order from cold traffic runs through ads, welcome discounts, content and time. Someone who has already bought, on the other hand, knows you, trusts you, and needs far less of a push to buy again. Lifting retention by even a few points can grow profits noticeably, because regular customers tend to raise their average order value (AOV) and buy more often (industry benchmark).

Question 3

How do you increase the repurchase rate in an online store?

Accepted Answer

The repurchase rate goes up when the experience after the sale is at least as good as the one before it. Too many stores polish every detail right up to "thanks for your order" and then leave the customer on their own. Here are the levers that actually move repurchase: - Proactive post-purchase support: don't wait for the customer to write in — get ahead of their questions about delivery, use and returns. - Upselling and cross-selling, done like a human: recommend the right product at the right moment, the way a seasoned shop assistant would, not with a barrage of pop-ups.

Question 4

What part does post-purchase support play in retention?

Accepted Answer

Post-purchase support is the moment a customer decides whether you're just another supplier or a brand worth trusting. That's where nearly all of retention is won or lost. A customer with a sizing problem, a return to sort out, or a product they can't figure out how to use is at a crossroads. If they find a real person who replies straight away and sorts the situation out, they walk away more attached to you than before. If they find a form to fill in and a reply three days later, they walk away sure they won't be back.

Question 5

How do you calculate the Customer Lifetime Value of an e-commerce store?

Accepted Answer

Customer Lifetime Value (CLV/LTV) is the total economic value a customer generates for your store across the whole relationship. It's the metric that gives every retention investment its meaning. The basic formula combines three variables: - AOV (average order value): how much the customer spends per purchase on average - Purchase frequency: how many times they buy in a given period - Length of the relationship: how long they stay a customer A practical version is: LTV = AOV × number of purchases per year × average years as a customer.

Question 6

Does live chat help bring customers back to buy?

Accepted Answer

Yes — and more directly than you'd think. Live chat with human agents affects repurchase because it steps in at the decisive moments, just as a doubt is about to turn into an abandoned cart or a lost customer. Almost 7 in 10 shoppers abandon their cart before checking out (source: Baymard Institute), often over a hesitation that the right answer would have cleared up in seconds. Real-time help recovers many of these sales, but the real effect on retention comes afterwards: someone who was genuinely helped by a real person tends to come back, because they associate your brand with an experience where somebody was actually there.
