Free SEO checker
Enter a domain or a page address. The checker measures 20 technical criteria on the live site and lists every issue with a fix.
What the checker measures
Access and redirects
The homepage answers 200 over HTTPS, http:// redirects to https with a 301, www and non-www merge into one host, and redirect chains stay at one hop.
Speed and weight
Time to first byte measured from the checker, whether HTML is compressed, and how heavy it is after compression.
On-page tags
Title, meta description, H1, canonical, meta robots, viewport, lang, image alt text, Open Graph, and whether the share image loads.
Can Google read it
Whether robots.txt blocks Googlebot, whether the sitemap is valid and on the right host, whether JSON-LD parses, and whether sampled internal links work.
