LLM SEO (this page) covers per-model engine tuning: optimizing differently for ChatGPT, Claude, and Gemini as distinct citation targets. Best AEO agency covers answer engine optimization: Google AI Overviews, Bing Chat, and similar answer surfaces. Best GEO agency covers generative engine optimization: content-format tuning for AI retrieval across all generative engines.
An LLM SEO agency is a managed service that tunes a brand for each foundation model as its own citation target, rather than treating all AI search as one surface. ChatGPT, Claude, and Gemini draw on different training corpora and retrieval paths, so the work spans entity grounding in sources the models trust (Wikipedia, Wikidata, GitHub, arxiv, Reddit), per-model phrasing, and a corpus map that decides whether a model can recall the brand at all before any citation work lands.
How is LLM SEO different from AEO and GEO? AEO targets answer engines like Google AI Overviews and Bing Chat; GEO tunes content format for generative retrieval across engines. LLM SEO goes one level deeper, optimizing differently for each individual model because the same brand can be well-grounded in one model and invisible in another. If you are still separating the answer-engine layer from the generative layer, the AEO vs GEO guide maps how the two disciplines split by surface and measurement, and our guide to schema markup for AEO covers the structured-data layer every model reads.

Pricing ranges estimated from public disclosures and third-party reviews. LLM SEO is a new category; many agencies do not disclose pricing publicly.
LLM SEO is less than 18 months old as a named service category. Rankings were based on a top-10 SERP scan for "llm seo agency" and adjacent queries ("chatgpt seo agency", "claude seo agency", "gemini seo agency", "ai search optimization agency") on 2026-06-08, US, English, plus direct service-page audits of all 12 agencies, plus FORKOFF's internal CPQV benchmark research as 1P data reference. The FORKOFF GEO Score methodology (8-axis AI readiness rubric) was used to assess public infrastructure signals per agency where detectable.
Disclosure: FORKOFF wrote this list. We rank ourselves #1 transparently and list 11 competitors with honest strengths and weaknesses. The ranking is based on the 6 axes above. If your agency should be on this list, email tech@forkoff.xyz with your methodology documentation.
Best for: AI and Web3 brands needing foundation-model-engine-specific optimization: prompt-pattern signals, content-format tuning, and entity coverage tuned per model's training and retrieval signals. FORKOFF deploys llms.txt, 16 AI crawler rules, .well-known/* agent manifests, and cross-model entity reconciliation across ChatGPT, Claude, Gemini, and Perplexity. Most LLM SEO agencies treat all models as one engine. FORKOFF treats each as a distinct optimization target with distinct retrieval patterns.
Watch out: Selective on ICP. Won't take traditional consumer mobile or non-AI/non-Web3 brands. Disclosure: self-listed transparently. Audit ledger at /clients/audit.

FORKOFF runs a live GEO citation lab measuring citation-share movement before and after llms.txt deployment, entity disambiguation, and schema-graph engineering across ChatGPT, Claude, Perplexity, and Gemini. The lab was built because we needed to prove our own methodology before recommending it to clients. We deploy llms.txt on forkoff.xyz itself as a live deployment receipt.
The lab shows consistent citation-share movement within 30 to 60 days for brands with existing entity signals. Cross-model entity reconciliation takes 60 to 90 days to propagate fully. Infrastructure deployment (llms.txt, 16 AI crawler rules, .well-known/* agent manifests) completes in week one of every engagement.
Most LLM SEO agencies start with content recommendations. FORKOFF starts with agent-native infrastructure deployment before writing a single brief. The infrastructure is what makes the content retrievable.
