Top AI SEO Agencies in 2025

In this article, we'll explore 6 agencies already offering generative engine optimization and AI SEO services as of June 2025.

This is an emerging field in digital marketing, so we recommend you choose an agency that's experimenting and innovating constantly. Those we chose below are showing clear signs of their skill in AI SEO.

What is AI SEO?

AI SEO, also known as GEO, LLM-O, AIO and various other acronyms, is about shifting your focus from optimizing purely for search engines like Google to optimizing for large language models (LLMs) like ChatGPT, Claude, Gemini, and Perplexity.

These models don’t rank content the same way Google does. Instead, they read, interpret, and generate answers based on patterns and associations in their training data or live web access.

To show up in their answers, your content needs to be LLM-readable and contextually strong.

That means:

1/ Make content easy for LLMs to read, interpret, and cite

LLMs pull from structured, high-confidence sources. They need content that’s clear, well-formatted, and consistent. Rambling blog posts with vague claims or clickbait-style headings get ignored. High-quality summaries, straightforward explanations, and entity-rich content get surfaced more often.

2/ Track brand mentions in AI-generated answers

LLMs don’t just show ranked links, they instead generate summaries and answers.

Being included means your brand or product must be recognized and contextually relevant.

You can track when and where your brand appears in ChatGPT, Claude, or Perplexity using prompt testing, search tools, or custom tracking workflows. This tells you if your content is actually working inside AI interfaces.

3/ Structure content for visibility in AI tools, not just Google

Google looks at backlinks, freshness, and technical SEO. LLMs look at clarity, relationships between entities, and semantic coherence. That’s why content built for GEO often uses:

• Clear headings and definitions
• Entity-based formatting (naming people, companies, tools, and categories directly)
• Short, direct explanations over keyword stuffing

Think like an explainer, not a search engine gamer.

4/ Use entity-rich, well-structured language

LLMs rely heavily on entities—names of people, products, companies, locations, etc.—and how they’re described and related. If your content clearly connects your brand to known categories or use cases, you increase the chance of being cited.

What should you look for in an AI SEO agency?

In our view, these are the most important attributes to look for in an AI SEO agency.

1. They don't pretend they know it all

This industry is still emerging. It's experimental. Nobody has concrete methodology that is guaranteed to work for the long-term.

That said, there are things that clearly work now. They should have an evolving playbook of tactics to implement to get you to the top.

2. They have a culture of testing and experimentation

Similar to a good SEO agency, the best GEO agencies will be always iterating and improving. They'll have a methodology that's proven to work - but will be adapting and refining it based on tests.

When vetting agencies, ask them: What tests are you running? What results are you seeing and how did you measure success?

3. They're truly great at SEO and content writing

Any AI SEO agency should have first earned their stripes in traditional SEO.

Not only are the most effective techniques and methodology similar, but the mentality for ranking in LLMs and search engines is the same.

When vetting agencies, ask them about their SEO successes and how their approach is similar for GEO.

Who is the best overall AI SEO agency for B2B brands?

Spicy Margarita stands out as the best AI SEO agency for B2B brands.

Spicy Margarita has big successes with traditional SEO. That knowledge and skillset translate well to AI SEO, and they're proving it.

Spicy Margarita works with B2B services and B2B SaaS companies. They've created content for famous B2B companies like Gong and OpenAI. Despite that, they remain affordable and often work directly with small companies and founders who don't yet have a marketing team.
