Google AdSense Shifts to Begin-to-Render Impression Measurement

Google AdSense is updating its method of counting display ad impressions starting on February 17, 2027. The new approach, called Begin-to-Render, will only count an impression once the ad has successfully loaded and started rendering on a user's device. This change aims to provide more consistent measurement and align with industry standards.

The current method counts an impression when an ad starts downloading to a user's device. However, this can lead to counting impressions that never actually rendered, as users may leave the page before the ad begins to load. By switching to Begin-to-Render, AdSense will no longer count these non-rendered impressions.

This change is expected to impact total impressions, potentially reducing the number of impressions counted. Details on this update can be found in a help document provided by Google.
