Getting cited in Google’s AI Overviews (AIO) has completely changed how companies think about search visibility. Back then, the game was all about securing the top blue link. Now, it’s about ensuring your brand is the source Google relies on when generating a direct summary for the user.
Traditional SEO playbooks weren’t built for this shift. Winning position zero today requires a dedicated approach to AIO Google result optimization, focusing heavily on structured data, entity authority and informative content.
To help you find the right strategic partner, we have compiled a list of the 10 best US-based generative engine optimization (GEO) agencies specializing in AI Overviews optimization. These are teams that can help you build an effective AIO strategy to secure a permanent spot in AI summaries and responses.
Editorial disclosure: No agency paid for placement on this list, and no entry was written or reviewed by the agency it describes. Rankings are based on our weighted scoring methodology and independent research.
The best GEO agencies for AI Overviews optimization in 2026 are Thrive Internet Marketing Agency (98/100), iPullRank (92), Siege Media (88), First Page Sage (84) and Go Fish Digital (81). We scored 10 agencies using a weighted model that prioritized generative search visibility (60%), based on 200 high-intent prompts tracked over a full year, alongside Google search performance, reviews, experience, reputation, service depth and market relevance. Thrive earns the top spot for driving +381 AI Overview citations (from zero), +250% organic traffic and +188% top-3 keyword rankings for a Texas-based medical clinic — reinforced by internal AI traffic results (+5,556% AI referral traffic, +1,078% ChatGPT growth), proprietary tracking tools (Thrive Score and Thrive Stats) and flexible month-to-month pricing. The full ranking below breaks down each agency by founding year, core strength, key services and best fit, so you can match a partner to your growth goals rather than name recognition alone. We review and update this list monthly as agencies’ performance and AI visibility evolve.
