how we classify
Every agency we index gets sorted by how it was built, not how it markets itself. Here's exactly what each tier means, how we assign it, and why it isn't a quality score.
Most directories and "best of" lists treat every "AI SEO agency" as interchangeable. In practice, there's a wide gap between a shop built from scratch for AI search and a twelve-year-old SEO agency that added a GEO service page last year. Neither is automatically better — but a buyer's expectations, and the right questions to ask, should be very different for each. Tiers make that distinction visible up front instead of leaving you to guess from marketing copy.
Built after 2024 specifically for AI search. No legacy SEO business.
These are the rarest agencies in the market. When we researched broadly for genuine pure-play examples, we found only a handful — most companies calling themselves "GEO agencies" have an SEO or marketing pedigree stretching back years, with AI visibility layered on top. A true pure-play doesn't have a gap between its founding and its GEO adoption, because there is no gap: GEO is the founding thesis, not an addition to one.
The closest real-world example we came across in earlier research — though not yet run through our full profiling methodology — is Genevate, which pairs GEO specifically with strategic PR for trust-driven verticals like law and healthcare, with no prior SEO practice behind it.
What to expect
Young shop where GEO is the majority of the offering.
Similar in spirit to a pure-play, but with more flexibility: the founders may have a general digital marketing background, or the agency may have started broader before pivoting hard toward AI visibility as its primary revenue line. The distinguishing feature is that GEO work makes up most of what the agency actually does day to day, even if it isn't the literal sole focus.
What to expect
Established SEO agency that added a dedicated AI visibility line.
This is where the overwhelming majority of the market sits, and it's where all fifteen agencies we've profiled so far landed. These agencies typically show a real, meaningful gap between their founding year and when they picked up AI/GEO work — we track this explicitly as the "origin story" on every profile.
The size of that gap varies a lot within this tier — SeoProfy's founder says they were testing AI tactics by 2022, years ahead of most peers, while others only picked it up around 2024. Both still count as Tier 3, because both had a substantial non-AI practice first.
What to expect
AI visibility folded into broader brand and PR strategy.
Larger agencies where GEO is one thread inside a much bigger brand, reputation, or PR practice — often serving large enterprise clients where AI visibility is a component of overall brand management rather than a standalone deliverable with its own case studies.
What to expect
For every agency, we look for two dates: when the company was founded, and when it started doing AI/GEO-specific work. The size of the gap between them is the main signal we use. A company with no gap — GEO was the founding idea — is a candidate for Tier 1 or 2. A company with a multi-year gap, where GEO was clearly added to an existing practice, lands in Tier 3 or 4 depending on scale and positioning.
This method isn't perfect. Founding dates sometimes conflict across sources (we've hit this directly — Victorious has three different founding years depending which source you check), and "when did they start doing GEO" is rarely a clean, publicly stated fact. But it's a more objective starting point than trusting an agency's own "we're an AI-first company" claim, which costs nothing to write on a homepage regardless of whether it's true.
This is worth repeating clearly: the tier tells you what kind of agency it is, not whether it's good. A Tier 3 agency with a decade of named case studies and hundreds of verified reviews can easily have stronger proof than a brand-new Tier 1 startup with nothing public yet. Use the tier to understand fit — do you want a narrow specialist or a full-service partner — and use the separate proof tier and Framework vs. Execution sections on each profile to judge actual quality and evidence.
As of this research pass, here's how our fifteen indexed agencies break down by tier — and why three tiers are still empty.
currently indexed agencies fall into Tier 3
agencies found yet in Tiers 1, 2, and 4 combined
genuine pure-play example (Genevate) identified in earlier research, not yet formally profiled
