Google Ads Lookalike Segments – July 2025 Updates by Georgi Zayakov
Google is quietly upgrading Lookalike Segments in Demand Gen campaigns, giving advertisers new ways to scale with precision.
You can now build lookalikes from richer sources like Android device IDs, GA4 audiences, and even YouTube users (with a higher 1,000-user match requirement).
This opens the door to more cross-platform targeting than ever before.
Another big shift: advertisers can now use the audience of a creator’s video as a seed list. It’s a game-changer for influencer campaigns or brands lacking deep first-party data.
Add to that the ability to combine up to 10 seed lists and adjust similarity settings (narrow, balanced, broad), and Google’s audience modeling just got a major upgrade.
