Question

When using views remarketing, does the 30-day lookback window reset each time a shopper views the product, or is it based on the first view only?

Answer 1

When using views-based remarketing (such as building audiences from users who viewed a product or product category), the 30-day lookback window resets each time the user triggers the event again, in this case, viewing the product.

Here’s how it works:

• Suppose a user visits a product on Day 1.

• They are added to the remarketing audience with a 30-day membership duration.

• If they return on Day 15 and view the product again, the 30-day window resets starting from Day 15.

• Their membership in the audience now extends to Day 45, assuming no additional product views.

This is true for most ad platforms like Google Ads, Meta (Facebook/Instagram), and GA4-based audiences used in Google Ads.

Why This Matters:

• Users who frequently return to the product stay in your remarketing funnel longer.

• You maintain the ability to re-engage with active shoppers even if they don’t convert in the initial visit.
