Why this selection is different from a directory
Mentionable isn't a generic directory. It's the platform built to drive AI visibility for brands. Our legitimacy doesn't come from a ranking algorithm. It comes from our direct knowledge of the field.
We know the field
Mentionable tracks more than 130,000 prompts every month across 7 AI models. We know what actually moves visibility inside LLMs. When we meet an agency, we can tell quickly whether they truly master the subject.
No commission
Agencies pay us nothing to appear on this page. We take no percentage on engagements. This selection serves your interest, not our revenue.
Hand-picked
Every agency is met by our team before being listed. Approach, depth, the way they work with their clients. No self-reported badges, no automated ranking, no inflated reviews.

Frequently asked questions
How is this different from a directory like Sortlist?
Sortlist and similar directories make agencies pay to appear. We don't. Our selection rests on our direct knowledge of the field: we built the platform that serious agencies use to drive AI visibility. We meet every agency before listing it.
Do you take a commission on the engagement?
No. You contact the agency directly, you sign with them, you pay them. Mentionable is not involved financially.
What if the agency doesn't deliver?
All the work happens inside your Mentionable account. You see the progress (or the lack of it) in real time, within the first weeks. No need to wait six months to know whether it's working.
Do these agencies work internationally?
Most of them, yes. Each profile lists the languages and countries the team operates in.
What's the difference between a GEO agency and an SEO agency?
An SEO agency optimizes for Google search results: rankings, backlinks, indexable content. A GEO agency optimizes for citations in LLM answers: ChatGPT, Perplexity, Claude, Gemini, Google AI Mode and AI Overview. Technical levers overlap (authority, structured content, trusted sources) but success signals, tools and measurement methodologies differ. Many SEO agencies add a GEO line without changing their delivery; the agencies listed here operate dedicated GEO workflows on Mentionable.
How much does a GEO agency cost?
Most engagements range from €1,500 to €8,000 per month depending on scope. Audit-only programs start around €2,000-€4,000 one-shot. Continuous monitoring + content execution typically runs €3,000-€6,000 per month for a brand tracking 30-80 prompts across 3-5 LLMs. Each agency profile shows its starting price when disclosed.
How do I evaluate a GEO agency before signing?
Check four things: (1) the LLM coverage — serious agencies track all 6 surfaces (ChatGPT, Perplexity, Gemini, Copilot, Google AI Mode, Google AI Overview), not just ChatGPT; (2) the methodology — monthly pipeline with tracking, fan-out analysis, content execution and measurement, not isolated audits; (3) the tracking stack — they should answer plainly which platform they use to measure citation share over time; (4) the case studies — real numbers, not vanity claims. Every agency in this directory has been vetted against these four criteria.
Should I hire a GEO agency or build the capability in-house?
In-house works if you already have an SEO/content team willing to add GEO to its scope and a tracking tool like Mentionable to operate the loop. Hire an agency if you want to move faster, lack internal SEO expertise, or need an outside perspective on positioning. Most brands start with an agency-led 90-day program then internalize the ongoing tracking once they understand the workflow.
