Buyers no longer start every search on Google. More of them now type a question into ChatGPT, Perplexity, Gemini or Google’s AI Mode, such as “which CRM is best for a small sales team?”, and read a short answer that names three or four brands. If your company is not in that answer, you were never on the shortlist.
That shift created a new discipline. It goes by several names: generative engine optimization (GEO), answer engine optimization (AEO), AI SEO or LLM optimization. The goal is the same. You want AI assistants to know your brand, trust it and recommend it when a buyer asks for options.
Many agencies now sell GEO, but they approach it in very different ways. Some focus on technical changes to your website. Others focus on content. A few focus on the off-site signals that AI models lean on most: mentions in trusted publications, “best of” lists, reviews and expert commentary. Below are seven agencies worth considering in 2026, what each one does best and who each one fits.
How we chose these agencies
We looked at four things:
- A clear GEO method. Does the agency explain how it gets brands into AI answers, beyond a renamed SEO package?
- Off-site and on-site work. AI models build their view of a brand from what other websites say about it, not only from the brand’s own pages. The strongest agencies cover both.
- Proof. Published case studies, research or tools that show the team understands how AI search works.
- Transparency. Whether you can understand the offer and the cost before a sales call.

1. Create & Grow
Create & Grow is a digital PR, link building and AI search (GEO) agency founded in 2023 by Georgi Todorov, who has built links since 2016. Before starting the agency, Todorov worked as an SEO manager and link builder at Semrush and grew his own site, ThriveMyWay, from zero to 100,000 monthly visits in six months before selling it in 2023. The agency works with brands of all sizes, from startups to large companies, and with agencies that resell its services white-label.
Its positioning is simple: help brands get recommended by ChatGPT, Google AI, Perplexity and Gemini, not just mentioned. The reasoning behind that is practical. When an AI assistant recommends a product or service, it usually leans on what trusted third-party pages say: comparison articles, “best of” lists, reviews and expert quotes. So most of Create & Grow’s GEO work happens off-site, on the sources AI tools already read.
What it offers:
- Done-for-you AI SEO: one monthly plan that finds the sources AI assistants trust for your category, gets your brand into them and then checks the answers AI tools give.
- Brand mentions and listicles: placements in listicles, reviews, comparisons and regular articles on DR 30 to 90 sites, which are the page types AI models quote most when they compare options.
- Expert quotes and digital PR: founder and expert commentary placed in publications, plus reactive and data-driven campaigns pitched to journalists.
- Link building: manual outreach on real websites with organic traffic, including SaaS, multilingual, iGaming and restricted niches. The agency does not use PBNs.
- AI on-page optimization: audits and fixes that make a site easier for AI crawlers to read and quote.
Proof: the agency publishes its case studies with numbers. They include over 140% organic growth for hosting company WPX from content strategy alone, and 1,100% organic growth in nine months for an AI platform that moved from page five to owning its brand search results. Create & Grow also publishes original research and free tools, such as a robots.txt AI bot checker and an llms.txt generator.
Pricing: all prices are published as monthly packages. Done-for-you AI SEO starts at €3,000 per month, brand mentions start at €1,500 per month for five placements, listicles at €1,750 per month and link building at €2,400 per month for eight links. AI on-page work starts with a €500 audit. Removed links and mentions are replaced free for up to two years while the client is active.
Why it stands out: it is one of the few GEO agencies that publishes every price and that does the off-site placement work itself rather than outsourcing it. Clients also work directly with the founder, which matters in a field this new.
Best for: brands and agencies that want to show up in AI recommendations for buying questions and want a clear monthly cost.
2. iPullRank
iPullRank is a New York enterprise SEO and AI search agency founded by Mike King, who developed the “relevance engineering” framework. The approach combines information retrieval, AI, content strategy, digital PR and user experience to make content more likely to be retrieved and cited by AI systems. King was named Search Engine Land’s AI Search Marketer of the Year for 2025.
The agency’s flagship is a six-month AI Search Strategy Program for enterprise brands. It has also published a free, book-length AI Search Manual and built AI search tools such as Qforia.
Pricing: custom, aimed at enterprise budgets.
Best for: large companies with technical teams that want a research-heavy strategy for AI search.
3. First Page Sage
First Page Sage is a long-running SEO agency, founded in 2009, known for a thought leadership approach to content. It now applies the same method to GEO, publishing expert-led content on a fixed schedule so that both search engines and AI assistants treat the client as an authority in its niche.
Its client roster has included large B2B brands, and the agency publishes its own industry research and rankings, which often appear in other “best GEO agency” roundups.
Pricing: custom. Third-party listings report monthly retainers in the five-figure range.
Best for: complex B2B companies, such as SaaS, medtech and manufacturing, with budget for a long content program.
4. Go Fish Digital
Go Fish Digital is a digital marketing agency that sells GEO alongside SEO, digital PR and paid media. Its GEO work focuses on structuring content so AI systems can retrieve, rank and summarize it, and it uses tools such as an AI Overview Analyzer and a semantic content audit.
The agency also built Barracuda, an AI marketing intelligence platform that maps how topics expand across search and AI systems and checks content before it goes live. Its digital PR team works on brand mentions in sources that AI models read.
Pricing: custom.
Best for: mid-size and larger brands that want Google AI Overviews and on-site content work supported by proprietary software.
5. NoGood
NoGood is a growth marketing agency that offers answer engine optimization as part of a wider program covering content, paid media and creative. Its AEO service combines strategy, earned media, technical optimization, content and AI search tracking.
NoGood works closely with Goodie, an AEO platform described as its sister company, which tracks how brands appear in ChatGPT, Gemini and Perplexity. That gives clients visibility data alongside the agency’s execution.
Pricing: custom.
Best for: funded startups and consumer brands that want GEO run together with paid and social growth.
6. Kalicube
Kalicube focuses on how search engines and AI assistants understand a brand or person as an entity. Founder Jason Barnard coined the term “Brand SERP” and has written books on Brand SERPs and Google Knowledge Panels.
Kalicube’s work centers on making sure Google and AI tools describe a company or founder accurately and positively, often starting with Knowledge Panels and the brand’s search results. It is less about winning “best X” queries and more about controlling what AI says when someone asks about you by name.
Pricing: custom.
Best for: founders, executives and companies whose brand is misdescribed or ignored by AI assistants.
7. Siege Media
Siege Media is a content marketing agency known for data-driven content, design and digital PR that earns links and coverage. It has extended that model to AI search, where well-cited, original content helps a brand appear in AI answers.
The agency publishes original data studies and free tools of its own, which is the same kind of citable content it creates for clients.
Pricing: custom, typically suited to larger content budgets.
Best for: established brands that want a large content and digital PR program that supports both SEO and AI visibility.
How to choose a GEO agency
Before you sign, ask every agency these questions:
- Which prompts will you track, and how? A good agency starts by measuring how often AI tools mention and recommend you today for the questions your buyers ask.
- Where will my brand appear? Ask for examples of the sites, lists and publications they place clients in, and check that those sites have real organic traffic.
- Is the work on-site, off-site or both? Technical fixes help AI read your site, but recommendations usually come from what other trusted sites say about you.
- What does it cost, and what is guaranteed? Be careful with anyone who promises a spot in ChatGPT’s answers. Nobody controls those answers. What an agency can promise is the work: the placements, the content and the measurement.
Final thoughts
AI assistants are becoming a shortlist engine for buyers, and the brands they name are the ones that appear most often in trusted third-party sources. The right agency depends on where your gap is. If AI tools misdescribe your brand, an entity specialist like Kalicube fits. If you are an enterprise that needs deep technical strategy, iPullRank is a strong option. If you want your brand placed in the listicles, reviews and articles that AI already reads, with clear monthly pricing, Create & Grow is the place to start.
