Best B2B AI SEO & GEO agencies

In the rapidly evolving digital age, B2B brands face unprecedented challenges—and opportunities—in search engine strategy. With the ubiquity of generative AI tools like ChatGPT, Gemini, and Perplexity rewiring the search landscape, traditional SEO is no longer sufficient. Enter the new field of Generative Engine Optimization (GEO) and AI-driven SEO, where agencies blend advanced technical skill with deep content strategy to improve visibility in both classic and AI-powered search results. This article investigates and compares leading B2B agencies at the cutting edge of AI SEO and GEO, revealing what sets them apart and how they’re delivering measurable business results.

Understanding Generative Engine Optimization (GEO) and AI SEO

Generative Engine Optimization (GEO) refers to tactics and strategies deployed to increase brand visibility within the output of large language models (LLMs) and AI-powered interfaces. Whereas traditional SEO focused on Google’s ranking algorithms for static web results, GEO demands content — and technical structure — that is discoverable, referenced, and cited by AI engines providing conversational answers or summaries (BeOmniscient, 2025).

Modern B2B buyers now consult not just Google but ChatGPT, Perplexity, and other AI platforms during their product research phase. Appearing in these AI-generated responses requires specialized, evolving techniques—from structuring content for AI parsing to tracking brand mentions within LLM output and optimizing content hubs for LLM “visibility” (SEOtheFxck, 2025). This paradigm shift is reshaping the playbook for agencies serving B2B tech and SaaS firms.
