Free GEO Checker: Test Your Generative Engine Optimization

What Is Generative Engine Optimization?

Generative Engine Optimization (GEO) is the practice of making your website easy for AI tools to discover, trust, and cite when generating answers.

When you ask an AI assistant a question, it pulls answers in snippets from multiple webpages. GEO aims for your website to be part of those sources.

Signals are more than just keywords. Whether your website contains an llms.txt, includes an 'about the author' section, dates your webpages, includes references, and is understandable and organized enough for an AI to comprehend the purpose of each page are all signals.

In summary, an easier-to-trust website that is clearly organized and understandable is more likely to be referenced in AI answers on virtually every platform, including ChatGPT, Perplexity, Gemini, and beyond.

Key Points: Why GEO and Google Rankings Are Different

• •AI referred web sessions grew 527% in a single year, making generative search an active traffic channel your site either captures or misses entirely.
• •The overlap between Google ranked pages and AI cited pages has dropped from 70% to below 20%.
• •Adding statistics to content improves AI visibility by 41%, and recently updated content appears 4.3 times more often in AI answers than older pages.
• •Website AEO GEO Checker is a free AI visibility checker that shows you exactly where AI engines trust your content and where they do not.

GEO vs AEO: What Is the Difference?

Both GEO and AEO focus on AI search visibility. They solve different parts of the same problem.

AEO focuses on how well a single page can respond to a question. It evaluates the presence of FAQ sections, schema markup, question-based headings, and answers at the top of the section to improve response efficiency.

GEO focuses on whether an AI should be cited as a trustworthy information source. This includes signals of AI author trust, how recent the information is, the presence of llms.txt, whether external citations are present, and how well it's structured. It assesses the information source's credibility.

Both are necessary for a fully optimized website. AEO focuses on making a page easy to cite, while GEO focuses on making the entire website a reliable source.

A page with a perfect FAQ section but no visible author, no dates, and no evidence behind its claims is still a weak source. A trustworthy site with poor structure can also miss citations because the answer is too hard to extract. The best results come from improving both together.

What the GEO Checker Tests?

We check 9 signals that determine whether AI tools discover, understand, and trust your site.

The Most Important GEO Signal: llms.txt

An llms.txt file is a plain text file placed at the root of your domain. It tells AI crawlers what your site is about. It also tells which pages are most important and what topics you cover.

It is like creating a sitemap for AI instead of search engines.

Most sites do not currently have that. This signals a huge opportunity. Instead of guessing which pages have important information, AI crawlers will have a list. This job is primarily editorial, which likely applies to small teams. You will be explaining your website in a formal, clear, and concise summary that is understandable by AI.

Our tool shows you in real time whether there is an llms.txt page on your site, the relevance of other versions, and the purpose of those versions. This GEO analysis works as both a quick GEO checker and a deeper GEO audit tool, free to run on any website, with GEO optimization recommendations included in every report.
