About Meridian Search
Meridian works on whether a brand gets named when a buyer asks an AI assistant for a recommendation. Their measurement practice samples prompts across ChatGPT, Perplexity, Gemini and AI Overviews on a weekly schedule.
They were the clearest of the GEO agencies we reviewed about the limits of that measurement, which is why they rank where they do.
Our verdict
Meridian is the most measurement-literate GEO agency we reviewed, and the only one that volunteered the limits of its own numbers before we asked. They sample prompts weekly across four answer engines and report citation rates rather than a fabricated share-of-voice figure. The work itself is unglamorous: structured data, source placement and content rewriting, on a retainer that takes a quarter to show movement.
Pros
- Weekly prompt sampling across four AI answer engines
- Honest about what their measurement cannot tell you
- Strong structured data and schema practice
Cons
- Results take a full quarter to show
- No conventional SEO offering, so you may need a second vendor
