Top Generative Engine Optimization (GEO) Agencies of 2025

Generative Engine Optimization (GEO) is having a moment—and honestly, it’s easy to see why. As AI-powered search tools like Google’s Search Generative Experience (SGE) keep evolving, brands are starting to rethink what it actually means to show up in search results.

It’s not just about stuffing the right keywords into a blog post anymore. GEO is about creating content that AI wants to feature—content that gets pulled into summaries, answers, and all the places your audience is paying attention. It’s less SEO 101 and more like future-proofing your brand’s visibility.

And some agencies are already ahead of the curve.

Case in point: First Page Sage just dropped a list of the Top GEO Agencies of 2025—and fun twist? Their blog post earned a featured snippet on Google. Whether that’s because of their schema markup, the way they structured their content, or just great timing, it’s definitely worth a look.

Here are a few of the top GEO agencies from that list—and why they’re getting attention right now:
