Ads and acquisition
What is marketing attribution?
Marketing attribution is deciding which ads, emails and touchpoints get credit for a sale.
A real store example
Uproot Clean washing machine cleaner advertorial: over 150 Meta ads linked here.
Northbeam, an attribution tool, is detected on this page. A shopper might read the advertorial from a Meta ad, search the brand a week later and buy from an email; attribution decides which of those touches gets the credit.
Getting marketing attribution right
Pick one model and keep it
Last click, first click and data-driven models give different answers. Comparing numbers across models misleads more than any one of them.
Check platform claims against orders
Add up what each ad platform claims and compare it with real orders. The gap shows how much is double-counted.
Watch MER alongside
Total revenue divided by total marketing spend doesn't depend on attribution, so it keeps everyone honest.
Ask Replo: "compare Meta's reported sales with Shopify orders by week".
Marketing attribution questions
- What is last-click attribution?
- Last-click attribution gives all the credit for a sale to the final touch before purchase, often a branded search or email. It's simple, but it undervalues the ads that introduced the shopper to the brand.
- Why do ad platforms claim more sales than I made?
- Each platform credits any sale inside its own attribution window, so one order can be claimed by Meta, Google and TikTok at once. Add their claims up and they'll often exceed your real revenue.
- Do I need an attribution tool?
- Not at first. UTM tags, your store's own reports and MER cover most decisions for a young store. Dedicated tools earn their cost once you spend across several channels.
