The 10 Best AI SEO Agencies in the USA (2026)

The short answer: the best AI SEO agency in the USA for SMBs and ecommerce brands is FactoryJet (yes, this is our list, and we explain exactly why we put ourselves first below). For deep technical and engineering work it's iPullRank; for B2B SaaS thought-leadership content it's First Page Sage; for enterprise scale with a proprietary tracking platform it's WebFX.

Here's why this question suddenly matters: 34% of US adults have now used ChatGPT, about double the share in 2023, climbing to 58% of adults under 30, and 28% of employed adults use it for work (Pew Research, 2025). When those users ask "who should I hire?", AI engines answer with citations, and a business that isn't cited doesn't exist in the answer.

We researched every agency below on its own website and in the live US search results on 06/17/2026. No pay-to-play, no invented review scores.

Disclosure, up front: FactoryJet appears at #1 on its own list. Almost every agency that currently wins this search query does the same, and we verified it. What we add is honesty about it, a methodology you can check, and nine real competitors with their actual strengths, including where they beat us.

Notice the pattern in that last column: almost none of these agencies publish a price, and that opacity is the norm in this market. It favors the agency, not you. We get into pricing models, and what they should cost, further down.

The 10 best AI SEO agencies in the USA, reviewed

1. FactoryJet, best for SMBs and ecommerce brands (disclosure: this is us)

We build and optimize for AI search the way we build websites: senior engineers, a transparent pricing model, and no annual lock-in. Every retainer covers both Google and the four major AI engines (ChatGPT, Perplexity, Claude, and Gemini) plus Google AI Overviews, with per-engine citation counts reported monthly.

Why we rank ourselves first for SMBs: clear scope-based pricing shared on a free call (no surprise tiers), month-to-month terms, a free AI visibility audit to start, and engineers, not account managers, running the work. Where competitors beat us: if you are an enterprise brand that wants a 40-person account team and a New York boardroom, iPullRank or WebFX is a better cultural fit. We are honest about that. See our AI SEO service.

2. First Page Sage, best for B2B SaaS thought leadership

A remote-first US agency known for long-form, expertise-driven content and its "Authority Content Architecture" approach. First Page Sage publishes detailed industry benchmarks and case data, and its client roster has included names like Salesforce, NerdWallet, and Verisign. If your growth depends on ranking and being cited for high-trust B2B topics, this is a strong fit. Pricing not published.

3. iPullRank, best technical and engineering depth

New York based, founded by Mike King, one of the most cited voices in technical SEO and AI search. iPullRank's "Relevance Engineering" framework and its widely shared AI Search Manual go deep on embeddings, information retrieval, and how language models actually select sources. Work has spanned brands such as SAP, American Express, HSBC, and Nordstrom. If you want the team that helped write the playbook, start here.

4. Onely, best technical SEO at global scale

A technical-SEO specialist serving US and European clients, with engineering-grade audits and a focus on crawlability, rendering, and the technical foundations AI engines depend on. Note for transparency: Onely is headquartered in Warsaw, Poland, not the US, though it serves US clients and ranks in US listicles. We include it because the technical depth is real, and we flag the location so you can decide.

5. WebFX, best enterprise scale with proprietary tracking

Harrisburg, Pennsylvania based and one of the largest performance-marketing agencies in the US. Its OmniSEO offering brings AI-visibility tracking and optimization into an enterprise package, backed by a large in-house team and proprietary reporting technology. If you need GEO delivered at scale alongside paid media and CRO under one roof, WebFX is built for that.

6. Siege Media, best content-driven GEO

San Diego based and content-led, Siege Media pairs editorial quality with proprietary tools (DataFlywheel and BlueprintIQ) to plan and measure content that earns links and AI citations. Its client work has included Asana, Intuit, Casper, and Zapier. If your AI-search strategy is fundamentally a content strategy, this is one of the strongest teams in the country.

7. Thrive Agency, best full-service with no lock-in

Arlington, Texas based, full-service, and increasingly AI-search focused through its ThriveAI work, including passage-level optimization, technical SEO, and digital PR. Thrive promotes no long-term contracts, which is rare for an agency of its size. A good pick if you want GEO bundled with broader digital marketing and the freedom to leave.

8. Searchbloom, best ROI-first reporting

South Jordan, Utah based, organized around its MERIT Framework spanning AEO and GEO, with reporting framed around revenue and ROI rather than vanity rankings. Month-to-month terms and recognition from Forbes and Search Engine Land. If you want an agency that talks in pipeline and revenue from day one, Searchbloom speaks that language.

9. 20North Marketing, best for local plus ecommerce

Atlanta based, with AI-visibility tracking built into its SEO work and a strong ecommerce profile as a Shopify Premier and Klaviyo partner. For local service businesses and DTC brands that want AI search handled alongside store and email growth, 20North covers the full stack in one place.

10. Go Fish Digital, best patent-driven technical analysis

A multi-office US agency known for unusually technical, research-led SEO. Go Fish built a Semantic Content Audit, an AI Overview Analyzer, and Barracuda, a tool that scores content against factors drawn from Google patents. If you want analysis grounded in how the algorithms are actually documented to work, few teams go deeper.

How much do AI SEO agencies cost in the US?

We are not going to invent numbers, because almost none of these agencies publish them, and a made-up range helps no one. Instead, here is how US AI SEO pricing actually works, and the three models you will encounter:

The bigger thing to watch is not the number, it is the transparency. Most US agencies hide pricing entirely and reveal it only after a discovery call, which favors them. FactoryJet shares scope-based pricing on a free call and starts with a free AI visibility audit, so you see the plan before you commit. For real dollar ranges and the cost drivers behind them (site size, competition, how many engines you track), read our companion guide: how much does generative engine optimization cost for a small business.

How to choose between them

Three filters separate real AI SEO capability from rebadged classic SEO. First, per-engine reporting: ask to see a sample monthly report with citation counts for ChatGPT, Perplexity, Claude, and Gemini separately, because most 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 a mystery team executes, quality varies. Third, contract terms: AI search changes every quarter, so month-to-month or short-notice terms keep your agency honest, and you should be wary of 12-month lock-ins on a discipline this young.

If you want the underlying playbook before you hire anyone, our generative engine optimization guide explains the work itself, and our roundup of the best GEO and AI visibility tools covers what good agencies use to track citations.

Methodology

We verified every agency on its own website and in live US search results on 06/17/2026: service pages, office locations, proprietary tools, and at least one differentiator each that can be checked at the source. We included Onely despite its Warsaw headquarters because it serves US clients and ranks in US listicles, and we flag the location openly rather than hide it. We excluded pure listicle publishers and directories that rank for this query but do not deliver the service themselves. FactoryJet's inclusion and position are disclosed self-placement, the same practice used by most of the current page-one results for this query, which we also verified. No agency paid to appear.
