Best generative engine optimization (GEO) agencies compared: 6 options by method, pricing and proof

Six agencies that sell generative engine optimization (GEO), the work of getting a brand mentioned and cited in answers from ChatGPT, Perplexity, Gemini and Google's AI Overviews and AI Mode. They are compared on what they focus on, how they measure AI answers, what they publish about price, where they work and what proof they show. Percepture and iPullRank publish prices; Go Fish Digital, GreenBanana and OneMagnify do not. Dardo wrote this comparison and is one of the six, so it appears last; the order is alphabetical, not a ranking.

Every fact about another agency comes from that agency's own website, linked, as read on 12 November 2026. Where an agency doesn't publish something, the comparison says so. No ratings, review counts or client names appear unless the agency shows them on its own site.

What a GEO engagement should include

A useful GEO program measures before it changes anything, then works on the site and on the pages AI answers cite.

• A fixed prompt set, the questions your buyers ask, measured on each AI engine over weeks, because answers change from day to day.
• Mentions and citations reported apart, per engine: an assistant can name your brand without linking to you, or cite your page without naming you.
• Technical access: AI search crawlers allowed in robots.txt and the firewall, and the facts in plain HTML rather than loaded by JavaScript.
• Pages that answer first, with the number, the audience and the year in the opening sentences of each section.
• Off-site mentions on the roundups, directories and reviews that AI answers already cite for your category.
• Reporting tied to visits and leads, not only to a visibility score.

How we compared the agencies

• Specialization: whether GEO is a main service or an add-on to SEO, digital PR or performance marketing.
• Method: which AI engines they say they track and what they report.
• Published pricing model: a starting price or range on their own site, or "not published".
• Location and time zone: where their team or offices are.
• Public proof: case studies or published research on their own site.

The six agencies at a glance

Go Fish Digital

Go Fish Digital is a digital marketing agency that sells GEO alongside SEO and digital PR. Its GEO page covers Google's AI Overviews, ChatGPT and Bing Copilot, and explains how Google's AI Mode splits a long question into sub-queries ("query fan-out") and what that means for content. Its about page lists offices in Boston, DC, Phoenix, Raleigh, San Diego and Jacksonville. It publishes case studies, and we found no published prices.

Choose Go Fish Digital if you want GEO run by a large SEO and digital PR team with offices across the US.

GreenBanana SEO

GreenBanana is an SEO agency that says it has provided SEO since 2009 and now builds GEO and answer engine optimization (AEO) together. Its GEO page describes four parts (technical access, entity and trust signals, answer-ready content and citation building), a baseline snapshot for your priority prompts, and tracking of prompts and citations across platforms that it iterates monthly. Its contact page gives an address in Beverly, Massachusetts, and it publishes AEO case studies. We found no published prices.

Choose GreenBanana if you want an established SEO shop to run a monthly prompt-and-citation loop for a small or mid-size company.

iPullRank

iPullRank is an AI search and SEO agency founded by Mike King that describes itself as working with enterprise and mid-market brands. Its AI search page lists program investment ranges of USD 30,000 to 150,000 (Emerging), USD 150,000 to 500,000 (Growth) and USD 500,000 and up (Elite), and it publishes a free AI Search Manual. Its about page introduces team members who work from their own home offices.

Choose iPullRank if you are a large brand with the budget for a research-heavy program and deep technical SEO.

OneMagnify

OneMagnify is a large marketing and data firm with a GEO practice. Its GEO page says its programs cover ChatGPT, Claude, Gemini, Perplexity and Google's AI Overviews and AI Mode, that it reports share of voice, sentiment and mentions alongside whether AI-referred visitors become leads, and that it doesn't guarantee citations or publish mass-produced AI content. Its about page mentions offices across North America, Europe and Asia, including a delivery center in Chennai. We found no published prices.

Choose OneMagnify if you are an enterprise marketing team that wants GEO tied to analytics and lead attribution, with delivery at scale.

Percepture is a New York agency that combines enterprise SEO, digital PR and GEO. Its GEO page says it tracks visibility across ChatGPT, Grok, Perplexity, Gemini and Google's AI Overviews and reports mentions, sentiment and referral traffic from AI platforms, and its pricing page says its AI search packages start at USD 3,500 a month.

Choose Percepture if you want PR-driven citations with a published monthly price.

Dardo (we wrote this list)

Dardo is the studio that wrote this comparison, so read this entry as our own description, not a review. Dardo is a team of three in Bogota, Colombia, on UTC−5 all year, that builds websites and sells GEO as part of its search work (facts). Its GEO service publishes an AI visibility audit from USD 690 and monthly AI visibility tracking from USD 299 a month, and its free AI visibility checker tests a site's robots.txt, llms.txt and structured data. On 12 November 2026 Ahrefs counted 162 AI citations of dardo.studio across 37 pages, 132 of them in ChatGPT and far fewer in Perplexity (10) and Google's AI Overviews (4).

Choose Dardo if you are a small or mid-size company that wants a published-price audit and monthly tracking, with the site fixes done by the team that builds websites. Look elsewhere if you need digital PR at scale or an enterprise program.

How to choose a GEO agency

Pick by budget and by where your gap is: on your site, or on the pages AI answers cite.

• If AI crawlers can't read your site, start with a technical audit; any of these agencies covers it, and our checker shows the basics for free.
• If your pages are fine but nobody cites you, the work is off-site: PR and roundups, where Percepture and Go Fish Digital lead with digital PR.
• If you are an enterprise brand, iPullRank and OneMagnify publish the most about method and scale.
• Whoever you hire, ask for the prompt set, the engines and the reporting cadence in writing, and compare like with like. Our guide to comparing design studios covers the questions to send every agency.
