# SEO Audit

Get a ranked list of a site's SEO problems, each with Google's rule. It is free, with no sign-up and no key.

## What it does

Find what to fix on a public website, for search engines and for AI answers.

- audit_site: SEO audit of up to 25 pages, failed rules by priority with the fix and source, a row per page with broken internal links and images without alt, plus Bing AI-search steps. - audit_page: the same page rules for one address. - local_ai_readiness: whether a local business site is ready to be named in AI search. - score_page_citation: a 0 to 100 citation score for one page, with fixes by biggest gain. - compare_citations: what the pages an AI answer cited share that your page lacks. - find_ai_questions: long searches to answer, from a pasted Search Console export. - check_ai_instructions: checks a site's llms.txt, llms-full.txt and AI page. - generate_ai_instructions: drafts an llms.txt for the owner to review. - audit_ai_search: grades a site on 12 on-site checks AI answer engines rely on, pass, partial or fail, with the 3 biggest fixes.

It reads only the public sites you name, respects robots.txt and refuses private addresses. It does not run JavaScript, query Google or AI engines, fetch directories, or measure rankings, traffic or backlinks. Scores and checks do not promise a citation, and the tools do not promise an effect on AI Overviews.

Nothing about you or the site is stored. Answers are cached for ten minutes. The optional judgement step, off by default, sends page text to a language model service. It and local checks are limited per day.

- Audits up to 25 pages of a site from its homepage and sitemap, with robots.txt respected
- Returns failed rules grouped by priority with the affected pages, the fix and the documentation link
- Checks titles, descriptions, headings, canonicals, noindex, structured data, share tags and image alt text
- Finds broken links, redirect chains, sitemap problems, thin and duplicate content
- Checks local business markup: name, address, phone, hours, map, and that the details match the page
- Compares pages: near-identical templated pages, little own text, hreflang returns, sitemap pages nothing links to
- Adds Bing AI-search steps to a site audit: AI Performance, IndexNow, content, with sources
- Audits one page with the full page rule set
- Optional judgement of page purpose and competing pages, limited per day
- Checks local AI-search readiness: services, locations, prices, FAQ, schema, NAP, proof
- Checks llms.txt, llms-full.txt, an AI page, home links, and name, product and fact consistency
- Drafts an llms.txt from the site's own public pages for the owner to review
- Grades 12 AI-search checks from a site's own pages, each pass, partial, fail or unknown, with the top 3 fixes
- Scores one page from 0 to 100 for citation chance, with fixes by biggest gain
- Compares pages an AI answer cited with yours: opening answer, headings, table, list, date, links out, schema
- Ranks 7+ word searches in a pasted Search Console export, with page, question heading and answer skeleton
