The Ecomm Analyst

Every December, plenty of brands look at their new-customer numbers and feel good. New-customer orders are up, new-customer CAC looks reasonable given how expensive attention gets, and the channels that drove them get credit going into January. Then the Q4 cohort’s repeat rate comes in well below the rest of the year, and the LTV assumptions built on those customers stop holding.

Gift shoppers are a big part of that. They are new customers in the sense that matters to your store, a first order from a new email address, but many of them bought for someone else and have no particular reason to come back. If you do not separate them, they distort several numbers you rely on.

Which numbers do gift buyers distort?

New-customer counts, new-customer CAC, and cohort LTV. A gift buyer lowers your new-customer CAC in Q4, because they convert from ads like anyone else, and then drags down the lifetime value of the cohort, because they do not reorder at the same rate. The channel that brought them in gets credit for acquiring a customer who was really a one-off. If you then set January budgets on Q4 new-customer ROAS, you are scaling a channel based on customers who will not behave like your usual buyers.

It also changes how you read the product mix. Gift orders cluster around certain products, such as gift cards, bundles, and whatever you merchandised as a gift, so a product can look like a strong acquisition driver in December and fall flat by March.

How do you identify gift orders?

With signals already in your order data. A shipping address that differs from the billing address is the strongest one, though it also catches people shipping to work. Gift messages, gift wrap add-ons, and gift card purchases are direct signals if your store collects them. Orders using a holiday promo code are worth flagging too. None of these is perfect on its own, but tagging orders that hit two or more gives you a gift segment you can track separately.

How should you adjust your reporting?

Split the Q4 cohort. Report new customers acquired between Black Friday and Christmas as their own cohort, with gift-tagged orders broken out, and compare their 90-day repeat rate against the same window from a normal quarter. That gives you a gift discount you can apply to Q4 new-customer numbers in future years. I explained how to read these curves in reading LTV and cohort curves without fooling yourself.

Judge channels on new-customer ROAS with the gift segment visible. If one channel’s December new customers are mostly gift buyers, its real acquisition value is lower than the headline. If another brought in self-purchasers at a slightly higher CAC, it may be the better one to scale into January. I covered the metric in what is new-customer ROAS, and should you optimize for it, and reading numbers during promotions in how should you read ROAS during a sale or promotion.

What about the people who received the gifts?

They are the upside. Someone who received your product as a gift and liked it is a potential customer you did not pay to acquire, but they will not show up in your data as connected to the original order. A post-purchase survey option like “received one as a gift” in the first half of the year is the clearest way to see that effect. If those answers rise after the holidays, some of the value you wrote off in the gift cohort is coming back through a different door.

How do you set this up before the rush?

Decide on your gift tagging rules now, while there is time, and make sure your attribution tool can show new versus returning customers and discount codes alongside channels. ThoughtMetric, for example, reports new-customer orders, new-customer sales, and cost per new-customer order by channel and campaign, and includes discount code as a reporting dimension. (Disclosure: ThoughtMetric sponsors this site.) Pair that with gift tags in Shopify and you can compare the two side by side. I listed the other pre-holiday checks in what to fix in your attribution before Black Friday.

A simple rule for January

• Treat December new-customer CAC as a best case, not a baseline.
• Tag gift orders using shipping address, gift messages, gift wrap, and gift cards.
• Report the holiday cohort separately and compare its repeat rate to a normal quarter.
• Scale January budgets on channels that drove self-purchasers, not just the most new orders.
• Use a tool that shows new-customer results by channel, such as ThoughtMetric (our sponsor), and add a gift option to your post-purchase survey.
