About SEO Checker
Run this SEO checker before a launch, after a redesign, or when a page loses traffic and you want the basics ruled out. Enter the address and click Analyze. We fetch the page as a desktop browser, along with its robots.txt, a made-up missing URL to test 404 handling, the http:// and www or non-www versions, and /favicon.ico. The report isn't stored.
More than 40 checks fall into six groups: Content, Crawling and indexing, Speed, Mobile and usability, Social sharing and Security. They cover title width in pixels, description, H1 and heading levels, alt text, noindex, canonical, robots.txt rules that block Googlebot, Bingbot or Baiduspider, sitemap, hreflang, JSON-LD errors, time to first byte, compression, render-blocking scripts, viewport, Open Graph, the HTTPS redirect and mixed content. You also get a Google and Baidu result preview and a table of key facts. Backlinks, Baidu weight and indexed page counts aren't included, as they come from scraping search engines. For a closer look at the head, open Meta Tag Checker.
