This free SEO checker audits up to 25 public pages within 45 seconds, respecting robots.txt. It groups SEO issues by category, shows affected URLs and explains fixes. Review category scores, duplicate metadata, broken internal links and sitemap conflicts. Compare a small competitor sample and export issues as CSV. Results describe server HTML, with coverage limits shown.

How to use this checker

Start with your website
Enter a public page URL. The audit follows same-site links to depth three and reads up to four sitemap documents. It checks at most 25 URLs, one request at a time. Optional competitor comparison checks up to five URLs within the same 45 second budget.
Review failures first
Start with delivery errors, unintended indexing exclusions and missing titles. Open an issue for its evidence, affected URLs and repair steps. Category filters help you focus; dedicated tools let you investigate further.
Check coverage before comparing scores
The report lists every attempted URL and the reason the crawl stopped. Query-string links, outside sites and excluded pages are skipped. HTML is capped at 1.5 MB per page. No JavaScript is rendered, and a bounded sample cannot prove a page is orphaned or indexed by Google.

Questions about this checker

It checks crawlability, indexing directives, titles, descriptions, headings, content, links, images, fetch performance signals, mobile markup, HTTPS, security headers, structured data, social cards, languages and AI search access. Site checks find duplicate metadata, broken internal links, sitemap exclusions and canonical conflicts within the pages actually visited.

Core delivery and indexing checks carry weight three; other scored checks carry weight one. Passes earn full weight, warnings earn half and failures earn zero. The score is earned weight divided by possible weight, rounded to a percentage. Advisory checks and missing observations are excluded. The report shows each weight and category score.

Export the issue list as CSV or print the report. The rerun link keeps your website and optional competitor in the URL. It does not store a public report: opening the link requires another run, whose result may differ. Results can be cached for five minutes.

No. These checks find basic technical and content signals. Search engines and AI assistants also assess relevance, sources and other factors this tool cannot measure. Use the AI visibility checker to inspect answers about your business.

That depends on your preferences. GPTBot and ClaudeBot collect training content. OAI-SearchBot and PerplexityBot support search answers. Google-Extended controls Gemini training and grounding. A blocked training crawler is a warning to review your choice, not an instruction to allow it.

llms.txt is an optional page guide. Its absence is advisory. Publishing it does not replace robots.txt access, make a page indexable or guarantee an AI citation.

The checker reads the HTML returned to our server without running JavaScript. A browser can add content after loading. Firewalls, location and caching can also change the response. Use the AI crawler check for live requests with crawler user agents.
