12 Best AI SEO Agencies in the USA (2026): Which AI SEO Agency to Hire

Which AI SEO agency should you hire? Pick the one whose strength matches your gap. For enterprise technical work, iPullRank. For content-led growth, Siege Media. For B2B software, Omniscient Digital. For online stores, OuterBox. For a small or mid-sized US business that wants one senior team on a month-to-month retainer, FactoryJet, which is our own agency (we disclose that below). An AI SEO agency gets your business named and cited when buyers ask ChatGPT, Perplexity, Gemini, Claude or Google AI Overviews who to hire.

That question matters more each year. 34% of US adults have used ChatGPT, about double the share in 2023, and 58% of adults under 30 have (Pew Research Center, June 2025). When those people ask "who should I hire?", the answer names a few businesses and skips the rest.

How we built this list: on 29 Sep 2026 we pulled Google US results for ai seo agency (about 1,600 searches a month), best ai seo agencies, top ai seo agencies and aeo agency. We read the five agency-published lists on page one, then checked every agency below on its own website the same day. Anything we could not find on the agency's own site, we cut.

Disclosure, up front: FactoryJet appears at #1 on its own list. So does every agency list we read on page one. What we add is a method you can check, sources for every claim, and eleven real competitors with the things they do better than us.

Which page do you need? This one compares AI SEO agencies. If you have already decided to hire and want scope, engine coverage and terms, our US AI SEO services page has that.

The 12 best AI SEO agencies in the USA, compared

The columns mirror what the top-ranking lists compare (offices, specialty, core services, own tools) plus two things most of them skip: the contract terms stated on the agency's own site, and how many of the five page-one lists name the agency.

"Not stated" means we could not find contract terms on the pages we checked. Ask. It does not mean the agency locks you in.

What the five page-one AI SEO agency lists agree on

We read every agency-published list on page one of Google US for these searches on 29 Sep 2026. Here is what each one covers, so you can see where our list sits against them.

Three patterns stood out. First, iPullRank and Siege Media appear on four of the five lists, Seer Interactive and Intero Digital on three, and First Page Sage, Omniscient Digital and Single Grain on two. Repeat appearances across rival publishers are the closest thing this market has to a neutral signal. Second, four of the five print dollar figures for AI SEO, and no two use the same tiers. Third, Google's AI Overview for ai seo agency on the same day cited six sites, including Coalition Technologies, Percepture and OuterBox, and named OuterBox for ecommerce and Go Fish Digital for digital PR.

Intero Digital is the one frequent name missing from our list. Its website blocked our check on 29 Sep 2026, and we do not describe services we could not see at the source.

The 12 best AI SEO agencies in the USA, reviewed

1. FactoryJet: best for small and mid-sized US businesses (disclosure: this is us)

FactoryJet was founded in 2014 and has served 500+ businesses. Our AI SEO retainer is month-to-month and covers ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews, with citations per engine and Google rankings in every monthly report. Founder Bhavesh Barot reads every enquiry and usually replies within 2 to 3 hours. For online stores, we are a registered Shopify Partner.

Where others beat us: authority and scale. We had 63 referring domains when we measured on 17 Aug 2026, and most of those are scraper sites we never earned. Our average Google position for ai seo agency was around 62 in September 2026. If you want a large account team and a long bench of public case studies, iPullRank, Seer Interactive or WebFX is a better fit. See our AI SEO service.

2. iPullRank: best for enterprise technical depth

iPullRank calls itself an enterprise and mid-market AI search agency. It was founded by Mike King, whom its site notes was named Search Engine Land's Marketer of the Year. Its services menu lists Relevance Engineering, generative engine optimization, AI search strategy, technical SEO and content engineering, and it publishes The AI Search Manual, a guide to how AI search picks sources. Its homepage carries a testimonial from an American Express digital strategy manager. It appears on four of the five page-one lists we read.

3. Siege Media: best for content-led GEO

Siege Media's homepage title reads "Full-Service GEO Agency for Brands". Its services run from BlueprintIQ and content strategy through GEO, content creation, digital PR, Reddit marketing and research reports. Its site lists offices in Austin, Chicago, New York and San Francisco, and its homepage case studies include Zapier and The Zebra. If your AI search plan is mostly a content plan, this is one of the strongest teams on the list. Four of five page-one lists name it.

4. First Page Sage: best for B2B lead generation

First Page Sage lists GEO / AEO and Agentic Search Optimization among its services, next to B2B and B2B SaaS lead generation and fractional CMO work. Its homepage says it does not lock clients into long-term contracts and ties its work to qualified leads and ROI. It also runs an academic publishing and citations section. A good fit if your AI search spend has to show up in the sales pipeline.

5. Seer Interactive: best for enterprise AI search with paid media

Seer describes itself as an enterprise AI search, SEO and paid media agency. Its site says it has worked in digital marketing since 2002 and is a Certified B Corp. Services include GEO, AI consulting, SEO, paid media, analytics and CRO, and it runs an in-house innovation product called SeerSignals. Pick Seer if you want AI search, paid search and analytics handled by one enterprise team. Three of five page-one lists include it.

6. WebFX: best for scale with tracking software

WebFX is headquartered in Harrisburg, Pennsylvania. Its OmniSEO platform, which the OmniSEO site says is powered by WebFX and SEO.com, includes a ChatGPT tracker, a Perplexity tracker and an AI Overview tracker, plus prompt research. The OmniSEO site cites 650+ experts. Its homepage features an AI search case study for Thompson Tractor. Choose WebFX if you want AI visibility software and a large team under one contract.

7. Thrive Agency: best for AI SEO inside full-service marketing

Thrive says it has grown businesses since 2005 and lists 25 cities, including Arlington, Texas. Its AI SEO page names passage-level content optimization, conversational query targeting, semantic SEO, topical authority and schema markup, and states "No Long-Term Commitment". Thrive also publishes its own list of the best AI SEO agencies, which ranked #1 on Google US for best ai seo agencies on 29 Sep 2026 and puts Thrive first.

8. OuterBox: best for ecommerce AI SEO

OuterBox lists offices in Akron, Ohio, Houston and Tuscaloosa, Alabama. Its AI SEO page names the deliverables: an LLM visibility audit, AI Overview and zero-click optimization, enhanced schema, keyword and entity mapping, prompt strategy and measurement. It also sells eCommerce SEO and ecommerce web design. Google's AI Overview for ai seo agency named OuterBox as the ecommerce pick on 29 Sep 2026, and the agency's page ranked #3 for that term in our pull.

9. Searchbloom: best for ROI-framed reporting

Searchbloom is based in South Jordan, Utah. Its homepage promises a dedicated analyst, custom strategies and no lengthy contracts. It has published a MERIT framework for AI search optimization and runs its own list of AI SEO companies, which ranks Searchbloom first and ranked #7 for ai seo agency on 29 Sep 2026. If you want an agency that talks revenue from the first call, Searchbloom speaks that language.

10. Omniscient Digital: best for B2B software companies

Omniscient Digital describes itself as an organic growth agency for B2B software companies, with offices in Austin, Texas and New York. Services include SEO strategy, generative engine optimization, conversion rate optimization and programmatic SEO. Its homepage includes AI visibility case studies for software brands. If you sell software to businesses and content is your growth engine, put Omniscient on the call list. Two of five page-one lists name it.

11. Go Fish Digital: best for tool-driven technical GEO

Go Fish Digital's GEO page lists three in-house tools: Barracuda, which scores page content against 14 factors drawn from Google patents; an AI Overview Analyzer; and a Semantic Content Audit that maps how AI systems read your site. It targets Google AI Overviews, ChatGPT and Bing Copilot. None of the five page-one lists named it, but Google's own AI Overview did, for digital PR. If you want analysis grounded in documented patents, few teams go deeper.

12. 20North Marketing: best for Southeast businesses wanting full service

20North is a full-service agency in Atlanta. Its services menu lists AEO next to SEO, ads, web development and email marketing, and Percepture's page-one list names it for GEO consulting. Choose 20North if you want AI search handled by the same team that runs your ads and email, with an office in the Southeast.

Which AI SEO agency is best for your situation?

• AI crawlers cannot read or render your site: iPullRank or Go Fish Digital.
• You need content that deserves citing: Siege Media or Omniscient Digital (B2B software).
• You run an online store: OuterBox, or FactoryJet if you are a small or mid-sized Shopify brand.
• You want AI visibility software as part of the deal: WebFX (OmniSEO).
• You want AI search, paid media and analytics under one roof: Seer Interactive or Thrive Agency.
• Your board wants pipeline numbers: First Page Sage or Searchbloom.
• You are a small or mid-sized US business that wants short terms and a named senior team: FactoryJet (our own agency).

How much do AI SEO agencies cost in the US?

Four of the five page-one lists print dollar figures, and their tiers do not match each other. We are not going to add a fifth set of numbers. Here are the three pricing models you will meet instead:

Watch the transparency more than the number. Most US agencies share pricing only after a discovery call, which favors them. FactoryJet offers a free AI visibility check, so you can see where you stand before any call. For the cost drivers (site size, competition, how many engines you track), read our guide on how much generative engine optimization costs for a small business.

How to choose between them

Three filters separate real AI SEO work from rebadged classic SEO. First, per-engine reporting: ask for a sample monthly report with citation counts for ChatGPT, Perplexity, Claude and Gemini listed separately. Some agencies track only Google AI Overviews. Second, who does the work: AI SEO is engineering-heavy (schema, llms.txt, log-file analysis, entity markup), so if a strategist presents and an unnamed team executes, quality varies. Third, contract terms: AI search changes every quarter, so month-to-month or short-notice terms keep your agency honest.

There is research behind the work itself. The paper that introduced GEO, GEO: Generative Engine Optimization (Aggarwal and colleagues, accepted to KDD 2024), found that content changes can raise a source's visibility in generative engine answers by up to 40%. If you want the playbook before you hire, our generative engine optimization guide explains the work, and our roundup of the best GEO and AI visibility tools covers what good agencies use to track citations.

GEO, AEO, AIO, LLM SEO: which one are you buying?

Four acronyms are being sold as four services. They are mostly one service with a different emphasis, and knowing which is which stops you paying twice for the same work.

The practical test: ask any agency selling one of these to describe the deliverable without the acronym. If it cannot, or the answer matches its classic SEO retainer, you are buying a rebadge. If it points at extractable answers, entity coverage, schema and per-engine citation tracking, the label does not matter.

Check one thing before you sign anything. If your robots.txt blocks GPTBot, ClaudeBot, PerplexityBot or Google-Extended, no content work will get you cited, because the engines cannot read the page. Any competent agency checks this in week one. Ask whether they have. Our AI search optimization services page lists what is in the engagement: crawler access, extractable structure, entity work and per-engine citation measurement.

Red flags on a US AI SEO agency's website

• Guaranteed rankings or guaranteed AI citations. Nobody controls what a model outputs. A guarantee here is either meaningless or measured against a metric so soft it always passes.
• Only Google AI Overviews reported. AI Overviews are the easiest surface to track. If ChatGPT, Perplexity, Claude and Gemini are not reported separately, they are probably not being worked on separately.
• Case studies with percentages and no baselines. "+340% AI visibility" means nothing without the starting number. Three citations to thirteen is +333%.
• A twelve-month lock-in on a young discipline. The engines change quarterly. Long contracts move that risk onto you.
• No named person on the work. If a strategist presents and the execution team is never named, you cannot judge who is doing it.
• Client logos with no matching case study or reference. A logo wall proves someone paid an invoice once.

How to run your shortlist this week

1. Set your own baseline first. Ask ChatGPT, Perplexity and Gemini the question your buyers would ask ("who are the best [your category] companies in [your city]") and write down who gets named. That list is your real competitive set.
2. Check your crawler access. Open yoursite.com/robots.txt and search for GPTBot, ClaudeBot, PerplexityBot and Google-Extended. If any are blocked, that is your first fix, and you may not need an agency to make it.
3. Shortlist three agencies. One large agency, one specialist, one owner-run shop. The spread tells you more than three similar quotes.
4. Ask each for a real monthly report from a live client, with the name redacted. This one request separates the agencies that measure from the ones that narrate.
5. Ask what they would do in month one. A good answer is specific and plain: crawler access, schema, fixing thin pages, building extractable answers. A weak answer is a long strategy phase.
6. Confirm the exit. Who owns the content, the schema and the tracking when you leave? Get it in writing before you start.

Steps one and two cost nothing and take about twenty minutes. Do them before you talk to anybody, including us, because they change what you should ask for.

Methodology

On 29 Sep 2026 we pulled live Google US results (DataForSEO, United States, English) for ai seo agency, best ai seo agencies, top ai seo agencies, aeo agency, ai seo services and ai seo company, including People Also Ask questions, which shaped the FAQ below. We read the five agency-published lists on page one: Optimist, Searchbloom, Percepture, Grow and Convert and Thrive Agency. We then checked every agency in our list on its own website the same day and kept only claims we found there. We dropped Onely from the earlier version of this list because we could not confirm a US office on its site, and we left off Intero Digital because its site blocked our check. Search volume comes from Google Ads data via DataForSEO. FactoryJet's inclusion and position are disclosed self-placement, the same practice used by every agency list we read on page one. No agency paid to appear.
