Compiled by CitedGEO, a GEO agency based in Kyiv, Ukraine. We left ourselves out of the ranking; the method and weights are below.
This list ranks agencies by how often they show up when a buyer asks Perplexity who the best GEO agency is, and by how much of their thinking and research they publish, and whether their pricing is public rather than kept behind a sales call. We wrote this list, so we are not ranked on it. You do not have to take our word for the order: every fact below is taken from the agency's own public pages or our measurement.

About the author of this list
CitedGEO is a GEO agency based in Kyiv, Ukraine. In the measurement behind the Perplexity weight, Perplexity named us in 0 of 20 answers. Our pricing is public: a one-off GEO audit at $750, monthly GEO at $1,500 a month, SEO + GEO at $2,200 a month. The audit method and measurement method are published, including what counts as a mention or a citation.
How to use this list
- Ask to see the measurement, not a screenshot of one lucky answer. A rate over several runs means more than a single response.
- Ask what counts as a mention or a citation. If an agency cannot define either in a sentence, it does not have a method, it has an anecdote.
- Check pricing before any sales call. An agency willing to publish a price in advance is agreeing to be judged on it.
Method
Each agency on the list is placed by five criteria, weighted as follows.
| Weight | Criterion |
|---|---|
| 30 | Perplexity visibility in our measurement |
| 25 | Published research and open methodology |
| 20 | Transparency: public pricing, a described measurement process |
| 15 | GEO specialisation: GEO as the main service, not one line among many |
| 10 | Free tools or resources |
Perplexity visibility is the largest single weight. We asked ten GEO- and AEO-related queries, each twice, on Perplexity on 26 September 2026: 20 answers, and counted which agencies were named. Full method and agency counts: our study of 96 Perplexity answers. We do not put a score against each agency here, because a single number would claim more precision than the method supports; the order above follows the weights, not a spreadsheet we are not showing you.
