What is Leidur?
Leidur is a free tool that audits how visible a website is in AI search — the answers given by ChatGPT, Gemini, Perplexity and Google AI overviews — as well as classic SEO. You paste one URL and get speed, content, GEO signals, an AI-visibility score and a prioritised plan to grow.
Why does AI search visibility matter now?
Most searches now end without a click: people read the AI answer instead of visiting sites. If AI assistants do not know or mention your business, you lose customers before they ever see your page. Leidur shows whether AI names you and what to fix so it does.
How does Leidur measure AI visibility?
Leidur asks a language model to generate real buyer questions for your niche, then checks live answers from the web to see whether your brand is mentioned and who is named instead. The result is a share-of-voice score: how often you appear versus competitors.
What exactly does the audit check?
Over 40 signals in six groups: AI readiness (what an AI crawler fetches), classic SEO (indexability, title, description, canonical, sitemap, robots.txt, structured data, alt text, broken links), speed via Google PageSpeed, GEO/AEO (llms.txt, FAQ, entity presence in Wikidata and Wikipedia, off-page mentions), trust and contactability, and security.
How long does an audit take?
About one minute. Leidur runs speed tests and live AI checks in parallel, then builds the report.
Is Leidur free?
Yes. Paste a URL and get the full report at no cost.
Which languages does Leidur support?
English, Russian and Estonian. Both the interface and the AI analysis are produced in the language you choose.
Do I need to sign up or install anything?
No. Leidur runs in the browser. There is nothing to install and no account required to run an audit.
What is GEO and AEO?
GEO (generative engine optimisation) and AEO (answer engine optimisation) are the practice of making a site easy for AI answer engines to read, quote and cite — through clear answer-first content, structured data, entity presence and third-party mentions. Leidur measures these and tells you what to improve.
How is Leidur different from a normal SEO checker?
Classic checkers grade you for Google's ten blue links. Leidur adds the AI layer: whether assistants actually mention you, what an AI crawler extracts from your page, and how strong your entity and off-page footprint is — the things that decide visibility in AI answers.
Does Leidur store the sites I check?
Leidur fetches public pages to analyse them and does not publish or sell your data. Reports are generated on demand for the URL you enter.
