You choose Influence consideration as your marketing objective and the Similar Audiences targeting option for a Google Display Ad campaign. In Google Display Ad campaigns, what are Similar Audiences built from?

In the context of Google Display Ads, Similar Audiences are built directly from remarketing lists because Google’s "lookalike" technology analyzes the shared characteristics and recent browsing interests of the users already present in those lists. By identifying common patterns among your existing site visitors or customers, Google can then find and target new individuals who exhibit nearly identical online behaviors but have not yet interacted with your brand. This targeting option is particularly effective for the "Influence consideration" objective, as it allows advertisers to expand their reach to a qualified "cold" audience that is statistically more likely to be interested in their products, thereby driving higher engagement than broader, interest-based targeting.
