10 Best AEO Agencies in the US (2026 Market Comparison)

Four criteria shaped the order.

Specialized AEO/GEO capability. Does the agency run prompt research, LLM monitoring, citation tracking, and entity work as a named service — not as a bolt-on to a legacy SEO retainer?

Verified client track record. Public case studies with numbers: citation counts, mention share changes, LLM-attributed sessions, pipeline from AI referrals.

Service focus breadth. Content, technical fixes, digital PR, and schema all matter for AI visibility. Single-lever agencies get penalized against teams that cover the full picture.

Technical AI readiness. Structured data, entity markup, crawlability for AI bots, retrieval-friendly page architecture — the plumbing that decides whether an LLM can quote you.

Agencies the brief did not surface with verified AEO evidence are not included.

We are Humanswith.ai. Our US headquarters is at 535 Mission St, 14th Floor, San Francisco, with engineering and operations in Tbilisi and an operating headquarters in 🇦🇪 Dubai. HumanswithAI, Inc., the US parent of the group, is a Delaware C-Corp incorporated in July 2026.

The company was founded in 2019 as a marketing agency, rebuilt around AI search by late 2025, and today has 11 people serving clients in the US, 🇦🇪 UAE and EU.

In an 8-week pilot in 2026, we moved Birdview PSA from a 0.9% to a 21.5% ChatGPT mention rate, with 103 unique LLM queries showing the brand.

Most AI visibility reporting stops at the first answer. Buyers do not. They come back with a budget limit, a request for proof, a question about red flags, or "why not the market leader?", and each turn can reshuffle the shortlist. So we run multi-turn buyer dialogs across ChatGPT and Google AI and measure survivability: whether a brand named in the first answer is still there at the final recommendation, and at which follow-up it dropped out.

That final recommendation is what a buyer acts on, which makes survival to the last turn the metric closest to a lead. On their public sites, the other nine agencies in this comparison describe prompt tracking and advise on follow-up questions. None describes measuring whether a brand survives a full buyer dialog.

Pricing is public and tiered:

• Starter — $149 per month. 100 prompts, 1 engine, 1 article per month.
• Growth — $1,497 per month. 500 prompts, 3 engines, up to 10 articles per month.
• Scale — $2,977 per month. 1,000 prompts, 4 engines, up to 20 articles per month.
• Outlier — $4,977 per month. 2,000 prompts, 6 engines, 2 scans, up to 40 articles per month.

Best fit: B2B founders and CMOs who want measurable mention-rate movement in ChatGPT and other engines without a six-figure enterprise commitment.

A representative result: within nine months, Case Status went from zero LLM presence to a dominant position across 39+ tracked prompts, with organic sessions up 19% quarter-over-quarter ^[1].

Best fit: B2B SaaS and enterprise tech companies with existing pipeline motion that need structured answer positioning tied to revenue, not impressions.

Omniscient Digital treats AEO as a question of whether a brand gets found, described correctly and recommended inside AI conversations. Its team works on content production, brand mentions, third-party validation and technical foundations. The agency reports LLM traffic converting at 30%, against 5% for traditional SEO, and its full-service engagements start at $120,000/year ^[2].

Best fit: mid-market to enterprise B2B software companies with budget for a strategic retainer, not a project.

Seer Interactive opens with research into which LLMs mention a brand, what those models say about it, and where its customers search. Many clients start with a diagnostic phase that sizes up current AI search standing and identifies what is worth testing. On its own funnel, Seer reports that 15% of inbound conversions since January 2025 came from people who discovered it through an LLM ^[3].

Best fit: large enterprises with complex product lines that need deep analytical insight into AI brand presence before committing to a campaign.

The published headline result: NoGood's AEO program for SteelSeries drove a 23x increase in AI search traffic and 27x growth in conversions from AI platforms year-over-year ^[4].

Best fit: high-growth startups and venture-backed SaaS brands that want AEO folded into a performance growth motion.

Foundation sells an ongoing AI visibility retainer aimed at B2B SaaS pipeline, along with AEO and GEO roadmaps built channel by channel, so a team can begin with one surface and expand later. The agency reports a citation increase of more than 200% for clients across Perplexity, Claude, Gemini and ChatGPT, and more than 165,000 AI citations generated last year. Named clients include Paychex, Bitly and Buildxact ^[5].

Best fit: B2B SaaS teams whose pipeline depends on showing up across the full LLM set, not a single engine.

Thrive runs GEO as a fully managed service, with technical work that covers AI SEO audits, competitor analysis, site speed and structured data. Its published results include one client passing 1,000 total AI citations through combined AI SEO and PPC, and another reaching a 610% increase in ChatGPT traffic. Thrive also cites 5,556% growth in total traffic from all AI platforms in 2025 ^[6].

Best fit: SMBs and mid-market companies modernizing a traditional SEO program without blowing up the existing stack.

Published results: Coalition grew Sugatsune's sessions from AI platforms by 261.6% and increased P3 America's LLM engaged sessions by 149.1% ^[7]. In the e-commerce set, Omni Cheer's AI search sessions rose 7,620% and GK Elite's rose 5,087% ^[7]. The agency cites 17+ years of experience and 860+ case studies ^[7].

Best fit: complex e-commerce platforms and high-volume technical sites where the bottleneck is schema and retrieval, not content volume.

Graphite builds its prompt lists from a client's own demand data, such as sales calls, Reddit threads and help center questions. Technical work is prioritized by what the agency's research links to AI retrieval and citation: structured data, entity markup, internal linking, crawlability and page architecture ^[8].

Best fit: consumer tech companies, high-traffic marketplaces, and growth-stage platforms that need content and technical work executed at volume.

One published outcome: AI content for category pages led to sustained visibility for a global eCommerce marketplace ^[9].

Best fit: enterprise CMOs who need a senior technical partner with information retrieval depth, not a content shop.

Under $5K/month, want to see citation movement fast. Start with Humanswith.ai's Growth or Scale plan. The pricing is public, the Birdview PSA pilot shows the measurement method, and the scope fits a founder-led team.

You need to know whether AI still recommends you at the end of the conversation. Humanswith.ai. We measure brand survival across multi-turn buyer dialogs, down to the follow-up where a brand drops out.

E-commerce with a complex catalog. Coalition Technologies or Thrive.

Enterprise technical depth. Foundation when the goal is sustained citation volume across every LLM ^[5].

Picking an AEO partner in 2026 comes down to three honest questions. How technically mature is your site today — can an AI bot actually parse it? How big is your client and budget profile — a $120K/year retainer fits an enterprise, not a seed-stage team? And which search ecosystem matters most — ChatGPT alone, or the full spread of Perplexity, Claude, Gemini, and Google AI Overviews?

Specialized agencies win on depth. A modern AI visibility platform like Humanswith.ai sits alongside them well — covering prompt tracking, mention-rate measurement, multi-turn buyer dialogs, and content production at a price point that lets a mid-market team run a controlled pilot before signing a larger engagement elsewhere. The two approaches are complementary, not competing.
