AI has shifted the rules of search almost overnight. Google’s AI Overviews now function as the “new front page” of the internet, often serving up direct answers instead of sending users to websites. For businesses, this means traditional SEO alone is no longer enough—your brand must now win the battle for AI answer inclusion. The challenge isn’t just ranking high for a keyword; it’s structuring and presenting your information so AI systems choose your content as the authoritative source.
In the AI SEO era, three things matter most:
Entity Clarity – AI models reward brands with consistent, reinforced identities across the web.
Answer-Optimized Content – Copy must be written and formatted for machine extraction, not just human reading.
Continuous Testing – Search models are evolving fast, and agencies must adapt just as quickly to keep clients ahead.
The agencies making the biggest waves are those who approach AI SEO as its own discipline—combining advanced technical SEO, entity building, content science, and real-time experimentation. Here’s a look at 10 agencies leading the charge in AI search optimization right now.
