Site health is the share of your crawled pages that have no errors, from 0 to 100 %.
- A page with no errors and no warnings counts fully.
- A page with warnings but no errors counts for 60 %.
- Notices do not lower the score.
- Redirects are not counted as pages.
Problems that affect the whole site, such as a missing HTTPS redirect, are counted on your home page.
As a rough guide, 90 % and above is very good, 70–89 % is fine with work to do, and below 70 % means some important problems need attention. The Health over time chart shows how the score changed between audits.
