A different discipline than the SEO you know.
Traditional SEO optimizes for search engine rankings. AI SEO — also called AI visibility or GEO (generative engine optimization) — optimizes for how language models understand, trust, and cite your business when generating an answer.
The two overlap, but they're not the same discipline — and most SEO agencies haven't caught up yet. Ranking #3 on Google doesn't mean ChatGPT knows you exist, or that Gemini would ever recommend you by name.
We optimize your visibility across
GEO, AEO, AI search optimization: one discipline, several names.
You'll see this work called several things. Generative engine optimization (GEO) is the term coined in a 2023 research paper. Answer engine optimization (AEO) puts the emphasis on being the direct answer an AI assistant gives, rather than one link in a list of results. AI search optimization and AI SEO are the plainer names for the same idea. They all describe one goal: making your business something AI systems can find, understand, trust, and name when someone asks a relevant question.
Citefast is an agency that does this work for you. We audit how ChatGPT, Gemini, Perplexity, and other AI models currently describe your business, restructure your content so they can read it, build the third-party mentions they draw on, and keep monitoring as the models change. The four services below are that process.

Traditional SEO vs. AI Visibility.
Goal
Rank higher on a results page you compete for clicks on.
Be the name AI actually states as the answer — no click required.
What "ranking" means
A position among 10 blue links — #1 through #10.
One of a handful of names an AI mentions by name in its answer.
Content that wins
Keyword-targeted pages built to satisfy search intent.
Clear, structured, fact-consistent content an AI model can read and trust enough to cite.
How authority is measured
Backlinks, domain authority, technical SEO signals.
Third-party mentions, consistent facts across the web, and content structured for AI to parse.
Example outcome
Your listing shows up on page 1, competing with 9 others.
ChatGPT says "X is a solid option for this" — no comparison shown, no competitors visible.
Everything it takes to become AI's answer.
