The 10 Best AI Search Optimization (GEO) Agencies in 2026

Last updated: August 2026

Who Are the Best AI Search Optimization Agencies?

The best AI search optimization (GEO) agency depends on your size and model: enterprise brands gravitate to technical specialists like iPullRank, B2B SaaS companies fit Optimist or Graphite, businesses wanting one full-service partner fit WebFX or Thrive, and PR-led AI visibility comes from firms like Crackle PR. This guide compares ten verified options, including us.

First, the disclosure most lists skip: this article is published by Cited, which sells AI search optimization. Nearly every "best GEO agencies" list ranking in Google today was written by an agency that placed itself on its own list. We are not pretending to be neutral; instead, we did two things those lists usually do not. Every fact below was verified on each agency's own website (not copied from other listicles), and we only report pricing that an agency actually publishes. Where we describe ourselves, we say so plainly.

How We Evaluated These Agencies

We judged every agency on the same five questions a buyer should ask:

1. What do they verifiably offer? Claims confirmed on the agency's own site, not third-party blurbs.
2. Do they publish pricing? Only 4 of the 10 agencies here (including us) publish any number at all. Unpublished pricing is not disqualifying, but it changes your sales process.
3. Who do they actually serve? Enterprise, SMB, B2B SaaS, or everyone.
4. What is their mechanism? Technical optimization, content production, earned media/PR, or a blend. AI assistants can be influenced through all of these; agencies differ in which lever they pull.
5. How is success measured? Look for a concrete measurement method, and ask who controls it.

The 10 Best GEO Agencies Compared

1. iPullRank: Best for Enterprise Technical GEO

iPullRank describes itself as a pioneering enterprise and mid-market AI search agency. Its Generative Engine Optimization programs span strategy, content, technical optimization, and measurement, built around its own "relevance engineering" methodology. The client roster shown on its site includes brands like Target, Adidas, American Express, and The Wall Street Journal.

Pricing: not published. Fit: enterprises that need deep technical work, not a packaged retainer.

2. WebFX: Best Full-Service Option With Published Pricing

WebFX is a large full-service agency with a dedicated ChatGPT optimization service covering content optimization, technical SEO, digital PR, authority building, and citation tracking through proprietary technology. It is one of the few large agencies that publishes an entry price directly on the service page, and the page candidly notes that companies without an established online presence should build other channels first, which is honest advice.

Pricing: starts at $3,000/month. Fit: mid-size businesses folding AI search into a broad marketing engagement.

3. Thrive: Best for Bundled SMB Digital Marketing

Thrive's AI SEO offering spans audits, E-E-A-T-focused content writing, review generation, link building, and technical SEO, and the agency positions itself as serving businesses of any size or budget across industries like healthcare and eCommerce. GEO is one line among many services rather than a specialization.

Pricing: not published ("affordable and flexible" per its site). Fit: SMBs and local businesses that want AI visibility bundled with everything else.

4. Optimist: Best for B2B SaaS With Transparent Tiers

Optimist is an SEO and content agency for B2B SaaS with an explicit AEO/GEO and AI visibility service line, tying AI visibility tracking to pipeline KPIs. It has one of the most transparent pricing pages in the category.

Pricing: free opportunity analysis; one-time roadmap at $7,500; advisory from $3,000/month; full service from $4,000/month. Fit: growth-stage B2B SaaS teams. Not a fit for local or ecommerce brands.

5. First Page Sage: Best for SEO + GEO Lead Generation

First Page Sage positions itself as an SEO + GEO agency building full-funnel organic lead generation, and publishes extensive educational research and benchmarks that themselves rank in AI-search-related SERPs. Client logos shown on its homepage include Salesforce, Logitech, and Verizon.

Pricing: not published. Fit: companies that want a combined SEO and GEO program from a research-heavy firm.

6. Siege Media: Best for Content-Led GEO

Siege Media positions itself as "the GEO agency that brands hire when ROI isn't optional," driving GEO primarily through high-end content production, digital PR, and research reports, with named tools for content strategy and data-backed updates. Clients shown include Zendesk, Zapier, Instacart, and HubSpot.

Pricing: not published. Fit: established brands whose AI visibility play is premium content at scale.

7. Crackle PR: Best for PR-Driven AI Visibility

Crackle PR is a senior-led B2B tech PR firm with a dedicated GEO and LLM optimization service that earns brand presence in ChatGPT, Perplexity, Claude, and Google AI Overviews through tier-1 earned media. This is a genuinely different mechanism: AI assistants cite authoritative coverage, and PR manufactures it.

Pricing: $12,000/month minimum, stated on its homepage. Fit: VC-backed and enterprise B2B tech. The floor excludes smaller brands.

8. Go Fish Digital: Best for GEO Plus Reputation Management

Go Fish Digital lists GEO as a distinct service alongside SEO, digital PR, and notably online reputation management. That pairing matters when AI answers surface third-party review content about your brand, which they frequently do.

Pricing: not published. Fit: organizations that need reputation management and AI visibility handled together.

9. Graphite: Best for AEO With Performance Marketing

Graphite is a growth agency offering Answer Engine Optimization alongside SEO and performance marketing, with a research-and-experimentation-led positioning and named clients including Webflow, Hinge Health, and MasterClass. It uses "AEO" rather than "GEO" as its category label; the work overlaps heavily.

Pricing: not published. Fit: growth-stage companies that want AI visibility integrated with experimentation-driven growth work.

10. Cited: Best for Fixed-Price SMB Work With a Written Guarantee

This is us, so judge accordingly. Here is what we can say verifiably, because everything below is published on this site:

• The audit and the complete fix-it-yourself report are free, before any sales conversation. You can evaluate our analysis quality without paying anything.
• Packages are fixed one-time prices ($2,997, $5,997, $9,997), not open-ended retainers, covering SEO, GEO, and AEO together.
• Every package carries a numeric score guarantee in writing: improve 20+ points, reach 75+, or reach 85+, or you get a full refund. The score comes from the same 120+ factor engine that produced your free audit, and you can re-run it free at any time to check our work.

Fit: small and mid-size businesses that want a fixed price, a measurable outcome, and the plan up front. Not a fit if you need enterprise-scale content production or PR placements; several firms above do that better than we do.

How Should You Choose a GEO Agency?

Ask these before signing anything:

1. Can I see the plan before I pay? Many agencies audit behind a sales call. Any agency should be able to show you what is broken before charging you to fix it.
2. What exactly is guaranteed, and who measures it? "More AI visibility" is not a commitment. Look for a number, in writing, with a measurement method you can verify independently.
3. Which mechanism fits my situation? Technical fixes and structured data (fast, foundational), content production (compounding, slower), or earned media (powerful, expensive). Match the lever to your gap, ideally identified by an audit first.
4. Does the pricing model fit? Retainers suit ongoing programs; fixed-scope projects suit defined problems. Six of the ten agencies here publish no pricing at all, which means budgeting starts with a sales call.
5. Do they practice what they sell? Check whether the agency's own site is readable by AI crawlers, carries clean structured data, and shows up when you ask an assistant about the category. It is a two-minute test that is surprisingly revealing.

The Bottom Line

The AI search agency category is young, crowded with self-ranked lists, and mostly opaque on pricing. The good news: the verification work is easy to do yourself. Every claim in this article came from the agencies' own websites, and yours should too, whichever direction you go.

If you want to see where your site stands before talking to anyone (including us), the free audit takes 90 seconds and hands you the complete fix list either way.
