The Top Generative Engine Optimization Services Agencies of 2025

Generative search is no longer a “future trend.” It's here, shaping how buyers shortlist and evaluate vendors. With ChatGPT, Gemini, Claude, and Perplexity becoming decision-making copilots, companies that fail to optimise for AI search risk disappearing from consideration altogether.

That’s why generative engine optimisation services (GEO) are surging. Specialised generative engine optimisation agencies are helping brands secure citations, recommendations, and factual accuracy across AI engines.

Below, we’ve compiled a comprehensive guide to the top generative engine optimization agencies of 2025, what makes them unique, and who they’re best suited for.

Generative Engine Optimization (GEO) ensures your brand is found, recommended, and accurately represented inside AI-generated answers.

Key components of generative engine optimisation services include:

1. AI Visibility Audits: How often does your brand appear in AI results vs. competitors?
2. Contextual Content Strategy: Building factual pages (pricing, compliance, integrations) that LLMs rely on.
3. Misrepresentation Management: Correcting outdated or false claims in AI outputs.
4. PR & Source Inclusion: Getting cited in listicles, review sites, and industry reports frequently referenced by LLMs.
5. Analytics & Tracking: Measuring citation share, recommendation share, and conversions attributed to AI.

Traditional SEO and GEO overlap by less than 30%. This statistic highlights a major shift: while SEO is still critical for ranking on Google, it does not guarantee your brand will show up inside AI-driven answers. In practice, this means a company could dominate page one of Google while being completely invisible in ChatGPT or Perplexity responses. GEO requires its own playbook, built specifically for how LLMs evaluate, summarize, and cite information.

With over 300 million weekly ChatGPT users, and rapid adoption across Perplexity and Gemini, decision-makers are increasingly consulting AI first when shortlisting vendors or evaluating options. Instead of searching Google for "best compliance software," a CMO or CIO is now more likely to ask ChatGPT to recommend solutions based on their context. That shift in buyer behaviour means companies that ignore GEO, risk being excluded from consideration entirely.

The top AI SEO agencies ensure you don’t just appear, but appear as the preferred choice.
