Artificial intelligence is changing how people search the web. Google’s AI Overviews now trigger on roughly half of tracked US search queries, and Perplexity has grown from 230 million monthly queries in mid-2024 to 780 million by mid-2025, according to its own CEO. If you are not optimizing for how these systems find and cite content, you are missing a growing share of how people discover information online.
This is where GEO, Generative Engine Optimization, comes in. Understanding your GEO score has become just as relevant as your traditional SEO position, yet most website owners have never checked theirs. Here is what a GEO score actually measures, why it matters, and what genuinely moves it.
What Is a GEO Score?
A GEO score is a numerical rating between 0 and 100 that measures how well your website is set up for AI-powered search engines and large language models to find, understand, and cite it. Unlike traditional SEO, which focuses on ranking in a list of blue links, GEO measures your visibility and citability inside a generated answer.
Your GEO score reflects how likely AI systems are to reference your content when generating an answer to a user’s query. A higher score means you are more accessible to AI crawlers and more likely to be cited as a source. As AI Overviews and AI-first search surfaces capture more query volume, this has become a real, measurable part of organic visibility, not a speculative future concern.
Why Your GEO Score Matters More Than Ever
The shift is not gradual. Google’s AI Overviews now appear on approximately half of tracked US search queries, according to multiple independent tracking studies in 2026, up sharply from where the feature stood just a year earlier. Meanwhile, Perplexity’s officially confirmed query volume more than tripled between mid-2024 and mid-2025, and third-party estimates put 2026 volume meaningfully higher still.
If your site is not built for these systems to parse and cite, you are losing visibility to a genuinely growing share of search traffic, not a hypothetical one. Traditional SEO is not going away, but the fastest-growing part of search discovery is now AI-mediated. Brands that address their GEO fundamentals now have a real head start over the ones who wait until AI search is the default.
What Affects Your GEO Score?
Several structural factors influence how AI systems interact with your website. These are the ones worth checking first.
The llms.txt File
An llms.txt file is a proposed, voluntary standard that gives AI crawlers a plain-language index of your site’s content. It is genuinely useful as a low-effort way to make your content structure explicit, but it is worth being honest about its limits: it is not an official W3C or search-engine standard, no major AI system has publicly committed to honoring it, and no credible independent study currently confirms a specific citation lift from adding one. Treat it as one small, cheap signal among several, not a guaranteed win on its own.
Meta Descriptions and Schema Markup
Meta descriptions still provide AI systems quick context about a page. More consequential is structured data: FAQPage, Article, and Organization schema give AI systems machine-readable facts (author, date, topic, Q&A pairs) instead of forcing them to infer those facts from prose, which measurably improves how easily your content can be extracted and attributed.
AI Crawler Access
Real, independently verified data on this: HasData’s AI Crawler Block Index, which examined 10,894 registrable domains in 2026, found that 10.3% of top websites block at least one AI crawler in robots.txt, with 7.9% specifically blocking GPTBot. That rate is far higher for news publishers specifically (50.5% block GPTBot), often a deliberate content-licensing decision rather than an accident, but still real and worth checking against your own robots.txt if you have not audited it recently.
If your robots.txt blocks these crawlers, you are invisible to the AI systems that respect robots.txt (not all of them do, which is a separate, more complicated issue). Auditing and updating your crawler permissions is one of the fastest checks to run.
