How do AI assistants decide who to recommend?
Assistants such as ChatGPT, Gemini, Claude and Perplexity answer from two places: what the model learned in training, and what it retrieves from the live web when it searches. When someone asks for the best firm for a job, the assistant synthesizes an answer from the sources it trusts most for that question.
Those sources are usually review directories, ranked lists, publisher articles and the websites that answer the question most directly. A company that only describes itself in marketing language, and that nobody else mentions, gives the assistant little to work with.
What is generative engine optimization?
Generative engine optimization, or GEO, is the practice of improving how often and how favorably AI assistants mention and recommend you. It builds on search engine optimization, but the goal is to be quoted inside a synthesized answer rather than ranked in a list of links.
Research supports the approach. In a study presented at KDD 2024, researchers from Princeton and collaborators found that adding citations, quotations from relevant sources and statistics to content improved its visibility in generative engine responses by up to 40% on their benchmark. That figure is a ceiling rather than a typical result, but the direction is clear: specific, sourced, quotable content wins.
What should you fix on your own website?
- 01
Say what you are in one sentence
Every page should make it easy to answer 'what does this company do and for whom?' A plain definitional sentence in the footer or about section helps engines get it right.
- 02
Answer real buyer questions
Publish short, self-contained answers to the questions buyers actually ask, as FAQ blocks and question-led guides. Lead with the answer, then the detail.
- 03
Add structured data
Mark up the organization, services, articles and FAQs with schema.org JSON-LD so machines can read who you are and what each page covers.
- 04
Let AI crawlers in
Allow the major AI crawlers in robots.txt, keep a current sitemap, and consider an llms.txt file that summarizes the site in plain text.
- 05
Use specific, sourced facts
Replace adjectives with specifics: timelines, scope, systems integrated, and outside facts with links to their sources.
- 06
Keep pages fast and server-rendered
If content only appears after heavy JavaScript runs, some crawlers never see it. Fast, server-rendered pages get read in full.
What has to happen off your website?
- Reviews on the directories AI engines cite for your category, such as Clutch for agencies and G2 for software, plus Google reviews where relevant.
- Named client stories and testimonials, with permission. Anonymous claims are hard for an engine to cite.
- Mentions in industry press, podcasts and guest articles where your buyers read.
- Consistent company profiles (LinkedIn, Crunchbase and similar) that use the same description as your site and are linked from it.
- Helpful answers in the communities where buyers ask questions, written as an expert rather than an advertiser.
How do you measure AI visibility?
Pick six to ten questions your buyers actually ask. Each month, ask them in ChatGPT, Gemini, Claude and Perplexity, and record whether you are cited, in what position, and who is cited instead. Save the raw answers so you can compare month over month, and track your share of voice against the competitors who keep appearing.
Key takeaways
- Engines recommend who others vouch for: third-party proof matters as much as your own site.
- On your site, lead with direct answers and specific, sourced facts.
- Structured data, open AI-crawler access and fast server-rendered pages make you readable.
- Measure with the same buyer questions every month across all major engines.
