TL;DR: We asked ChatGPT, Perplexity, and Claude who the best AI SEO agencies are, logged every name they gave, then spent a day fact-checking all of them. Nine real agencies made the list below, ranked by published AI-search proof, pricing transparency, and verifiable reviews. Two names the engines gave us did not survive the audit: one is a PR-syndication mirage, one is a startup that mass-publishes lists ranking itself first. We are on this list too, we wrote it, and we show you our own weak cells so you can discount our bias with receipts.
Most "best agencies" listicles are written by whoever owns the page. This one starts from a different place: the engines' own answers. In July 2026 we ran logged probes asking the three major AI assistants open questions about this category. The firms below are here because the AI put them there, or because they are established category leaders we added for completeness (each entry says which). Every fact carries a source, and where a firm publishes nothing, the cell says "not published" instead of a guess. Our methodology is the same one behind our Q3 AI Visibility Report.
How to read this list
Five things we scored, because they are the five things a buyer can actually verify:
- Named by AI engines in our logged July 2026 probes (yes/no, with counts)
- AI-specific services actually offered (their exact terminology)
- Published AI-search proof (case studies with AI metrics, not classic SEO numbers relabeled)
- Pricing transparency (published or quote-only)
- Verifiable third-party reviews (Clutch/G2, counted)
The comparison table
| Agency | AI named them | AI-search proof published | Pricing published | Reviews (Clutch) | Focus |
|---|---|---|---|---|---|
| The 66th | Yes (4x) | Yes, strongest of anyone | No | 10 | Boutique, mixed |
| Directive | No (added: category leader) | Yes (1 named case) | No | 56 (4.8) | B2B SaaS |
| Single Grain | Yes (3x, local probe) | Yes (3 cases, some vague units) | No | 12 | B2B, broad |
| iPullRank | No (added: category leader) | No (classic-SEO framed) | No | not verified | Enterprise |
| First Page Sage | Yes (3x) | No (logos only) | Yes ($2K-12K/mo) | not verified | Enterprise B2B |

| Breadchaser.ai (us) | Yes (see our own audit) | Yes (1 named case) | Yes ($95-997/mo) | 0 (we just audited ourselves) | US health/fitness/wellness |
The nine, ranked
1. The 66th (Vancouver, BC)
The best published AI-citation proof we found anywhere: Hedra (an a16z-backed AI video company) at +1,150% ChatGPT-attributed revenue in four months, AetherHaus (a Vancouver wellness business) at 89 AI citations and 120x traffic in nine months, all named clients with individual case pages (the66th.com/case-studies). Boutique, founder-led (Liam Lytton), 10 Clutch reviews. Pricing not published. One honesty note our audit turned up: they also run satellite pages on free Google surfaces to farm AI visibility for themselves, a tactic on the gray edge of the playbook they sell. It works. Decide how you feel about it.
2. Directive (Irvine, CA)
The B2B heavyweight with the most verifiable reputation on this list: 56 Clutch reviews at 4.8. Their GEO page publishes a real AI case, Case Status (legal-tech SaaS) taken from zero LLM presence to positioning across 39+ tracked prompts in nine months (directiveconsulting.com). They frame the work as GEO + AEO + AIO in one program. Pricing quote-only. If you are a funded B2B SaaS company, this is the safest large pick on the list.
3. Single Grain (Los Angeles, CA)
Eric Siu's shop has the broadest AI service surface here: four distinct offerings (AEO, LLM SEO, GEO, and "Search Everywhere Optimization"). Their AEO page publishes AI-specific client numbers, including SmartRent at +345% LLM referral traffic (singlegrain.com/agency/aeo-services/). Honest flag: some headline figures use units nobody can check ("136 Total AI Visibility"). Pricing quote-only, 12 Clutch reviews. The engines named them in our own local-market probe, unprompted.
4. iPullRank (New York, NY)
Mike King's firm is the most technical operation in the category. They coined "relevance engineering," published a free open-source query fan-out tool (Qforia) and the AI Search Manual, and work at true enterprise scale (Target, Amex, SAP). What they do not publish: AI-search-specific client outcomes or pricing. If you want the deepest technical bench and can pay enterprise rates, start here. If you want receipts specific to AI citations, they make you take it on reputation.
5. First Page Sage (San Francisco, CA)
They claim the first dedicated GEO service offering (May 2023) and they are the only large firm on this list that publishes pricing: GEO tiers from $2,000 to $12,000 per month, itemized on their own blog (firstpagesage.com). That transparency earns them this spot. What is missing: any published AI-search case study. The service page shows Fortune-500 logos and no outcome numbers.
6. NP Digital (San Diego, CA)
Neil Patel's 950-person global agency. Their real differentiator is tooling: Ubersuggest's AI Search Visibility features, which they own and bundle for clients. AI-specific case studies: none published (the claim is "100+ AEO and GEO campaigns analyzed," without names or numbers). Pricing quote-only. The pick if you want AI search folded into a full-funnel program at global scale and do not need public proof first.
7. Omniscient Digital (Austin, TX)
The most established boutique here (2019, ex-HubSpot and ex-Shopify founders, clients like Jasper and Adobe) and refreshingly direct about cost: full-service engagements start at $10,000 a month, stated on the homepage. Their published proof is excellent but classic-SEO denominated (+810% organic sessions for Jasper); AI-citation numbers are not published. They partner with Peec AI for measurement rather than building their own. Serious B2B SaaS budgets only.
8. Inject Digital (Manchester, UK)
The smallest firm on the list and the closest thing we have to a mirror: an AI SEO agency exclusively for healthcare and wellness brands, founded in 2024 by an ex-aesthetics nurse, from £650 a month. Published proof is thin (keyword rankings for two clinics, no AI-citation metrics) and there is no third-party review footprint yet. It is on this list because an engine named it in our probes and because vertical focus is exactly what we think this category rewards. UK aesthetics clinics should have it on their shortlist.
9. Breadchaser.ai (Austin, TX). That's us, and here is the honest row.
We are the AI SEO agency for health, fitness, and wellness businesses in the US. What we can prove: we took Advanced Recovery Cryo to #1 on both Google and ChatGPT in 15 days, and that client booked 4,457 appointments in 2025 (the case study). We publish our pricing ($95/mo analytics to $997/mo done-for-you), our playbook (free, all of it), and our own scores, including the bad ones: our latest local probe scored 2 of 10 on ChatGPT, and our directory audit last week found us on 0 of 8 major platforms. That last row in the table is not a typo. We are the youngest brand on this list and we are running our own playbook in public until the scoreboard says otherwise. If that transparency is worth more to you than a decade-old logo wall, see where you stand first, free.
The two names AI gave us that did not survive the audit
This is the part no other listicle gives you, and the reason to distrust unaudited "AI recommendations."
AIQ Labs. Named 4 times in our probes, more than most real agencies. It is not an AI SEO agency. It is a Halifax dev shop selling AI websites and receptionists, with zero Clutch or G2 reviews, no named clients we could find, and a homepage that returned the title "My Google AI Studio App" when we fetched it. Its AI visibility comes from paid press-release syndication with titles engineered as LLM bait ("Best AI Receptionist Platform 2026"). The engines ate it.
Maximus Labs. Also named repeatedly. A real, registered SF startup, founded 2025, zero Clutch reviews. Its visibility mechanism is dozens of programmatic "Top 10 AEO Agencies" pages on its own domain, one per vertical, ranking itself. Google has started penalizing exactly this pattern of self-serving listicles, and it is why this page you are reading names its own bias, shows its own weak cells, and links its methodology.
The lesson for buyers: AI assistants currently repeat whoever manufactures the most citations, not whoever does the best work. Audit the names. It took us one day and the receipts are linked.
Five questions to ask any AI SEO agency
- Show me an AI-search-specific case study with a named client and a dated metric. (Most cannot.)
- What is your price? (If the answer needs a call, the answer is "more than you planned.")
- How do you measure AI visibility, and can I see the raw prompts? (Share of voice over a fixed prompt set is the honest unit.)
- Which of your own category's AI answers do you appear in? (Make them run the probe live.)
- Who writes the citations you earn, humans or your own domain? (You now know why this one matters.)
Method: probes run July 7-13, 2026 across ChatGPT, Perplexity, and Claude with logged raw responses; every agency fact verified against first-party pages on July 15, 2026, sources on file; firms change, so we re-verify quarterly alongside the AI Visibility Report. Corrections: nick@breadchaser.ai and we will fix it with a changelog line, not quietly.
