Best GEO agencies in 2026: the transparency ranking

There was no ranking of GEO agencies that explained what it ranked on, so we built one. Every list we found was published either by an agency that appears in it or by a vendor selling a competing product, and none sourced its figures. One 2026 ranking grades agencies partly on pricing transparency while publishing twelve prices it attributes to no source, several of which we could not find anywhere on the named agencies' own sites.

What this ranks, and what it does not

Plainly, before the results: we do not rank quality of work. We have not been a client of any of these firms, and a quality score assigned from the outside would be worthless. We rank transparency, which matters more than it sounds when you are buying a service whose results are hard to verify.

Six criteria, all verifiable on the agency's own site, read on 16 September 2026.

• A published price, or at least a stated starting figure.
• The scope spelled out: engines tracked, prompt volume, deliverables.
• Engagement terms published: minimum length and notice period.
• A described measurement method, not just a promised one.
• Named client references.
• An identifiable legal entity: company name, address, registration.

The result: 6 of 24 publish a price

That is the finding. Of 24 US-marketed GEO and AEO agency sites we loaded, six published a price and eighteen routed us to a proposal request. Three 2026 directories confirm the pattern: Searchbloom's list of ten publishes nothing and says so, and AEO Vision's directory of sixty-plus carries no per-agency pricing at all.

France, for what it is worth, is more transparent: 10 of 18 French agencies checked the same day publish a rate.

The agencies that publish the most

• RevenueZen, Portland: the most complete grid we found. Six tiers from $3,000 to $15,000 a month, each with its deliverables listed, month to month with no long-term contract. Their grid also shows where measurement sits: a quarterly AI visibility audit at $10,000, a monthly one at $15,000.
• Percepture, New York: four tiers from $3,500 to $10,000+, priced by content volume, two to eight pieces a month, with digital PR from $4,500 as a stated add-on.
• Avante Visibility, Las Vegas: the clearest one-off offer, a flat $5,000 GEO audit delivered in about ten business days, 90-day re-measure included, no retainer.
• Digital Elevator: priced per sprint from $3,000, ongoing off-site work from $3,495 per 30-day cycle, full three-pillar program $9,000 to $24,000+, and explicitly no required retainer.
• WebFX: a single published figure, GEO services at $3,000 a month, with the deliverables named.

A sixth agency publishes a full tier grid with minimum terms, which would place it high on the criteria, but names no team, no city, no clients and no legal entity anywhere on its site. It fails the sixth criterion outright, so we left it out rather than rank it on the other five.

On engagement terms, the spread is wide

Where terms are published at all, they diverge sharply. Siege Media asks clients to commit to a six-month-plus horizon. Thrive advertises no long-term commitment as a selling point. RevenueZen bills month to month. Most of the rest publish nothing, which in practice means the term is set in the contract you are shown after the sales call.

How to get into this ranking

There is nothing to buy and nothing to trade. If your agency does GEO work and meets the criteria above, email contact@trytadow.io with a link to your public pages and we will check it like the others, on the same six points. Position depends on what you publish, not on what you offer us in return, and we would rather say so before anyone asks.

We will keep this page updated as we verify more, with the date of each reading. An agency that starts publishing its rates moves up. That is the whole point.

If you do not need an agency at all

Part of what these retainers cover is automatable, particularly citation tracking and monthly reporting. RevenueZen's own grid prices a monthly AI visibility audit at $15,000 a month, which is $180,000 a year for a cadence software runs daily. If your need is measuring visibility and fixing a catalog, a tool does that for a fraction. If your problem is authority you do not have yet, no software fixes it and one of these firms is the better investment.
