The SEO agency market is well-established. Thousands of firms worldwide specialize in keyword research, on-page optimization, link building, and technical audits. A newer category is emerging: the GEO agency — a firm that specializes in Generative Engine Optimization, the practice of making brands visible in AI-generated answers. The two share some DNA, but the skills, tools, and deliverables are meaningfully different.
What an SEO agency does
A traditional SEO agency focuses on improving a website's rankings in search engine results pages. Core services typically include:
- Keyword research and strategy — identifying high-value search terms and mapping them to content.
- On-page optimization — title tags, meta descriptions, heading structure, internal linking.
- Technical SEO — site speed, crawlability, mobile optimization, Core Web Vitals.
- Link building — acquiring backlinks from authoritative domains to improve domain authority.
- Content strategy — planning and producing content designed to rank for target keywords.
- Reporting — tracking rankings, organic traffic, and conversions through tools like Google Search Console and analytics platforms.
The SEO agency's success is measured in rankings, organic traffic, and revenue attributed to organic search.
What a GEO agency does
A GEO agency focuses on making brands visible and accurately represented across AI-powered platforms. The work includes:
- AI visibility audits — assessing how AI systems (ChatGPT, Perplexity, Claude, Gemini) currently perceive and represent a brand.
- Crawler accessibility — ensuring AI crawlers can render and extract content from the site, including identifying JavaScript rendering issues, missing structured data, and content that is invisible to AI.
- Structured data implementation — deploying comprehensive schema markup that helps AI systems understand entities, relationships, and factual claims.
- Adaptive rendering — configuring different content representations for different AI crawlers, optimizing each for the specific system's processing model.
- Brand narrative management — monitoring and influencing how AI systems describe a brand, correct inaccuracies, and position the brand relative to competitors.
- Cross-platform measurement — tracking brand mentions, citations, and sentiment across multiple AI platforms over time.
The GEO agency's success is measured in AI citation frequency, brand mention accuracy, and share of voice in AI-generated answers for category-relevant queries.
Key differences
Different optimization targets
SEO agencies optimize for Google's ranking algorithm. GEO agencies optimize for how multiple AI models process, understand, and cite content. The signals that matter are different — backlinks are less relevant in GEO, while content extractability and structured data are more important.
Different tooling
SEO agencies rely on tools like Ahrefs, SEMrush, and Google Search Console. GEO agencies need tools that can simulate AI crawler behavior, render pages as AI systems see them, and track brand mentions across AI platforms. This is a newer tooling category with different technical requirements.
Different skills
SEO agencies need expertise in keyword research, link acquisition, and Google's algorithm. GEO agencies need understanding of how LLMs process information, how retrieval-augmented generation works, and how different AI systems make citation decisions. The technical depth around AI systems is a prerequisite that most SEO agencies don't yet have.
Different timelines
SEO results typically compound over months as rankings improve and organic traffic grows. GEO results can shift faster because AI models update frequently and retrieval systems re-crawl on different schedules. But GEO also requires ongoing monitoring because a model update can change how your brand is represented overnight.
Do you need both?
For most brands, yes. SEO still drives the majority of organic traffic, and traditional search is not disappearing. But AI-generated answers are capturing a growing share of informational and evaluative queries — the queries that shape purchase consideration. A brand with strong SEO but no GEO strategy will be visible in Google but absent from the AI answers that increasingly influence buyer decisions.
Some SEO agencies are adding GEO capabilities. Some GEO-native firms are emerging. When evaluating either, ask specific questions: Can they show you how AI crawlers see your site? Can they measure your brand's presence across ChatGPT, Perplexity, and Claude? Do they understand adaptive rendering and AI-specific structured data?
The market is evolving
The GEO agency category is early. Standards are still forming, and many firms are still defining their methodologies. But the need is real: AI systems are becoming a primary discovery channel, and brands need specialized expertise to manage their presence across these platforms. The agencies that build genuine GEO capabilities — not just SEO with a new label — will define the category.
