How to use this page
1. Paste a live URL
Stay on this page. Host, HTTPS, and path update as you type — the full audit renders below the form.
2. Read the SERP preview
Title and description become the blue link and snippet. Check intent, not only length.
3. Fix headings
One H1. Use H2/H3 for the words customers actually search.
4. Close technical gaps first
HTTPS, canonical, viewport, sitemap, robots.txt before adding more copy.
5. Canonicalize hosts
Use the redirect checker for www vs apex and the domain-age tool (RDAP) for registration date.
What each check means
meta description
Affects click-through. State a real offer in one sentence — avoid keyword stuffing.
H1 and heading outline
One H1. Headings should be readable sentences, not image alt text alone.
canonical / redirects
Consolidate www and HTTPS with 301s. Do not canonicalize with long-lived 302s.
sitemap and thin pages
URL count is not the goal. Prefer unique pages with clear intent in the sitemap.
