What the SEO checker looks at
Title and meta-description length, a single clear H1 and sensible heading order, image alt coverage, canonical URLs to avoid duplicate content, Open Graph and Twitter cards for social sharing, JSON-LD structured data for rich results, and whether a robots.txt and sitemap.xml are present and discoverable.
Fix the most severe issues first
Each finding explains the problem and how to fix it. The Top priorities list at the start of the report shows the most severe issues across all modules.
Frequently asked
- Does this check technical SEO?
- Yes. It covers crawlability (robots/sitemap), canonicalization, structured data and metadata, plus Core Web Vitals via the performance audit.
- Can I check a page before it's published?
- The page needs to be reachable over the public internet, so publish it to a staging or live URL first.
