Georgi Zayakov shared that Google Ads has expanded Lookalike Segment capabilities:
- New Seed Sources
You can now create a lookalike using
• Android device IDs
• Google Analytics audiences
• YouTube users (requires 1,000 matches vs. 100 for others) - Audience Segments Based on Creator’s video
Use the audience of a creator’s video (not your own) as a seed, great for influencer-led strategies.
- Up to 10 seed lists can be combined per segment
- Choose from narrow, balanced, or broad settings depending on your reach vs. relevance goals

Great move for brands looking to scale without over-relying on first-party data.
