Meta Ads
Retargeting campaigns often have the best ROAS in an account. That does not necessarily mean they are the best place to put the next dollar.
Warm audiences contain people who already visited, added to cart, searched for the brand or purchased before. Many of them would have had a high probability of buying without another ad.
If a shopper adds a product to cart, sees a retargeting ad that evening and completes the order the next morning, Meta may attribute the purchase. The ad may have helped. It may also have simply appeared during a journey that was already going to end in a sale.
Look for: extremely high reported ROAS compared with the rest of the business; small audiences with high frequency; large overlap with email/SMS flows; returning customers dominating reported purchases; total store revenue barely changing as retargeting spend increases.
Instead of only asking what Meta reports, compare periods, geographies or controlled audience groups where possible. Does blended efficiency improve? Does overall purchase volume increase? Are more customers completing carts?
You may find that retargeting is useful but cannot absorb unlimited budget.
The answer is rarely “turn off all retargeting.” Use it intentionally for reminders, objections, product proof and offers, but keep enough budget focused on creating new demand.
If retargeting is claiming a large share of your Shopify revenue and you are unsure how much is truly incremental, send us an inquiry. We can review the attribution and budget split.
