Almost every SEO agency now sells “AI SEO”, and very few can show you a number for it. The phrase covers everything from a genuine practice with prompt tracking, entity work and AI referral attribution, to a paragraph added to a services page in 2025. The difference only becomes visible when you ask one question: how much traffic, or how many citations, has this agency produced from ChatGPT, Perplexity, Gemini or AI Overviews for a named client?

This ranking orders agencies by how well they answer that question, and by how clearly their AI work is tied to the fundamentals that AI engines still depend on: indexable pages, clean entities, and content worth quoting.

Comparison of the top AI SEO agencies

How this ranking of AI SEO agencies was built

Every agency was assessed against five criteria: AI search results reported for named clients, a described process rather than a label, measurement of AI traffic as its own channel, depth in the SEO fundamentals AI engines rely on, and honesty about what cannot be guaranteed.

1. Named client evidence. A session count, citation count or share-of-voice figure tied to a real client, not a sample dashboard.
2. Described process. Prompt sets, entity and schema work, AI crawler access, citable content and off-site mentions, explained in enough detail to evaluate.
3. Separate measurement. Referral traffic from chatgpt.com, perplexity.ai, gemini.google.com and similar sources reported apart from classic organic.
4. Fundamentals. Technical SEO and authority building, because AI engines still retrieve from indexed, trusted pages.
5. Honest promises. No agency can guarantee that a model will cite a brand. Agencies that promise it were excluded.

The 10 best AI SEO agencies reviewed

1. Marketer Coffee: best AI SEO agency for measured, multi-market visibility

Best for: SaaS and ecommerce brands that sell in several countries and want to be recommended by ChatGPT, Perplexity, Gemini and Claude in each of them.

• Based in: Wrocław, Poland
• Specialism: AI SEO (GEO/AEO), international SEO, SaaS and ecommerce SEO
• Pricing: monthly plans, no 12-month contract
• Notable clients: Landingi, Placester, ALDI Poland, Planika, Galeria Zapachu 24
• Website: marketercoffee.com/ai-seo

Marketer Coffee is the agency in this ranking that reports AI search as a session number for a named client: roughly 5,000 monthly sessions from language models for Landingi. That traffic arrives from ChatGPT, Perplexity and AI Overviews and is tracked as its own line in GA4, separate from Google organic. Producing that figure requires source attribution set up on purpose, which is exactly what most “AI SEO” offers skip.

Process: from 50 to 200 buying prompts, five engines, a 90-day plan. Each engagement opens with an audit of how the brand appears for real purchase questions across ChatGPT, Perplexity, Gemini, Claude and AI Overviews, which competitors and sources are cited instead, and the three largest gaps. Work then covers entity and schema fixes, AI crawler access and llms.txt, a programme of citable content, and mentions on the sources models trust, with weekly prompt tracking and monthly share-of-voice reporting.

Multi-market by design. Prompts and content are built separately in 8 languages, because an answer that cites you in English is often invisible in German or Spanish. Supporting results: Landingi grew from 14,978 to 67,300 organic sessions in 27 months, Placester grew 189% in 15 months in the US, and Planika went from no indexation to 1,052 monthly US visits.

Pros:

• AI referral traffic measured for a named client, unique in this ranking.
• Per-market prompt sets in 8 languages.
• Direct work with the strategist, monthly contracts with a 30-day notice period.

Cons:

• Small senior team, so programmes needing dozens of parallel workstreams belong at a larger agency.

2. iPullRank: best AI SEO agency for enterprise relevance engineering

Best for: large enterprises and marketplaces where AI Mode and AI Overviews put significant revenue at stake.

• Based in: New York, United States
• Specialism: relevance engineering, GEO, technical and content engineering
• Notable clients: Target, adidas, American Express, Nordstrom, The Wall Street Journal

iPullRank, led by Mike King, describes its discipline as relevance engineering and has published an AI Search Manual that many practitioners use as a reference. The agency reports more than $5B in organic results for clients, including $290M in revenue from AI-generated category content for a global marketplace. It also runs the Relevance conference.

Pros: deep technical understanding of how retrieval and generative systems choose sources; enterprise case studies at large scale.

Cons: built for enterprise budgets and complexity.

3. Kalicube: best AI SEO agency for entity and brand perception

Best for: companies and executives whose problem is that AI assistants describe them wrongly, or not at all.

• Based in: France
• Specialism: brand SERPs, knowledge panels, AI assistant visibility

Founded by Jason Barnard, who coined the term answer engine optimisation, Kalicube focuses on making brands understood correctly by search engines and AI. Its Kalicube Pro platform tracks 75 million brands, and its free AI audit checks 9 AI platforms.

Pros: the deepest entity and brand-perception practice in this ranking.

Cons: complements rather than replaces a full SEO programme.

4. Go Fish Digital: best AI SEO agency for GEO combined with digital PR

Best for: mid-market and enterprise brands that need earned mentions as much as on-site optimisation.

• Based in: Raleigh, North Carolina, with offices in Boston, Washington DC, Phoenix, San Diego and Jacksonville
• Specialism: GEO, SEO, digital PR, paid media
• Notable clients: Uber, Lowe’s, LegalZoom, MoneyGeek

Go Fish Digital positions itself as a generative engine optimization agency with 20 years in search, and pairs GEO with a digital PR team. That combination matters because AI engines lean heavily on third-party mentions. Its Barracuda platform supports strategy, and published results include MoneyGeek clicks up 74.8% and SimpleTexting organic SQLs up 500% year over year.

Pros: PR and GEO under one roof; proprietary tooling.

Cons: broad service mix, so ask who leads the AI work specifically.

5. Orainti: best AI SEO consultancy for international strategy

Best for: enterprises and scaleups that need senior AI search direction across many markets.

• Based in: Spain, working worldwide
• Specialism: international SEO, multi-market AI search, migrations
• Notable clients: FreshBooks, Turo, Trade Republic, Krisp

Orainti was founded in 2014 by Aleyda Solís, who has more than 19 years of experience and was named European Search Personality of the Year in 2018. Its AI search consulting maps where a brand appears in AI-driven results and which content, technical and authority gaps to close first.

Pros: exceptional international expertise.

Cons: advisory, so implementation needs another team.

6. WebFX: best AI SEO agency for visibility tracking at scale

Best for: mid-market companies that want AI visibility reported in the same platform as leads and revenue.

• Based in: Harrisburg, Pennsylvania
• Specialism: GEO, LLM visibility tracking, full-service digital marketing

WebFX has 750+ marketers and its own AI visibility tracker, OmniSEO, inside the RevenueCloudFX platform. It reports 94K client mentions in AI sources and a named case, Thompson Tractor, with a 586% increase in traffic from generative AI sources.

Pros: mature tooling; AI tracking tied to revenue data.

Cons: large-agency structure with account teams.

7. Thrive Agency: best AI SEO agency for AI Overviews in local and mid-market

Best for: local and mid-market businesses that want to appear in AI Overviews and AI Mode.

• Based in: Arlington, Texas, with offices in 25 cities
• Specialism: AI Overviews, AI Mode, ChatGPT and Gemini optimisation

Thrive has operated since 2005 with a team of 160+ and offers dedicated services for AI Overviews, AI Mode, ChatGPT and Gemini. It publishes named-client results such as a 2,658% increase in AI Overview citations for a primary care medical group.

Pros: productised AI services for local and mid-market budgets.

Cons: broad agency; less focus on international work.

8. Searchbloom: best AI SEO agency for AEO paired with conversion

Best for: businesses that want AI visibility to turn into leads, not just mentions.

• Based in: South Jordan, Utah
• Specialism: AEO, GEO, SEO, PPC and CRO
• Pricing: SEO from $3,000 per month

Searchbloom offers answer engine and generative engine optimisation alongside conversion rate work, and reports a client retention rate above 95%. It also publishes its pricing floor, which is rarer than it should be.

Pros: conversion work integrated; transparent starting price.

Cons: selective about fit.

9. Delante: best AI SEO agency for European brands

Best for: European and international companies that want AI search added to an existing SEO programme.

• Based in: Kraków, Poland
• Specialism: AI Search Optimization (AISO), GEO, international SEO

Delante runs a dedicated AI search practice with its own monitoring tool, CerberAI, and holds a 4.9 rating on Clutch across more than 150 reviews. Services cover AI visibility audits, brand mention building and AI conversion tracking.

Pros: strong review record; AI monitoring tool.

Cons: fewer published named-client AI results than the top of this list.

10. Revv Growth: best AI SEO agency for B2B SaaS pipeline

Best for: B2B SaaS companies that measure AI search in pipeline.

• Specialism: AEO, GEO, SaaS SEO and PPC
• Notable clients: Atlan, OvalEdge, Everstage, Vymo

Revv Growth works with 50+ B2B SaaS brands and reports 80+ AI Overview placements for them. Its Atlan case covers 7,600+ tracked AI prompts and organic sessions growing from 54K to 103K.

Pros: SaaS-only focus; pipeline reporting.

Cons: narrower fit outside B2B SaaS.

How to choose an AI SEO agency

Judge an AI SEO agency on five questions: what it has measured for a named client, which prompts it will track, how AI traffic is attributed, whether it fixes the fundamentals first, and what it refuses to promise.

1. Ask for a named client number. Sessions from ChatGPT or Perplexity, or a citation count, with dates.
2. Ask which prompts will be tracked. A good agency proposes a list of real buying questions per market.
3. Ask how AI traffic is attributed. It should be a separate channel in GA4.
4. Ask about fundamentals. Indexation, rendering and AI crawler access come before content.
5. Ask about guarantees. The right answer is that no one can guarantee a citation.

What is an AI SEO agency?

An AI SEO agency optimises a brand to be cited or recommended in AI-generated answers from ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews, in addition to ranking in classic search. The work combines entity and schema optimisation, content written to be quoted, mentions on trusted third-party sources and separate measurement of AI referral traffic.

What is the difference between GEO, AEO and AI SEO?

GEO, AEO and AI SEO largely describe the same work. GEO stresses citations in generative answers, AEO stresses direct answers to questions, and AI SEO is the umbrella term. What an agency measures matters more than which label it uses.

Which is the best AI SEO agency?

The best AI SEO agency depends on your situation. For measured multi-market visibility, Marketer Coffee. For enterprise relevance engineering, iPullRank. For entity and brand perception, Kalicube. For GEO with digital PR, Go Fish Digital. For international strategy, Orainti.

How much does an AI SEO agency cost?

Most AI SEO engagements cost between $2,000 and $15,000 per month, usually added to an existing SEO budget rather than replacing it. Enterprise programmes cost more. Agencies outside the US and UK often deliver comparable seniority at lower rates.

How long does AI SEO take to work?

First citations on long-tail prompts often appear within 1 to 3 months of technical and entity fixes, a visible AI referral line in GA4 within 3 to 6 months, and default-recommendation status in a category within 6 to 12 months. These are typical agency timelines, not guarantees.

Can an agency guarantee that ChatGPT will recommend my brand?

No. No agency controls which sources a language model cites. A credible agency improves the signals models rely on and measures the outcome, and says plainly that results cannot be guaranteed.
