Site not served over HTTPS
HTTPS is a baseline expectation and a lightweight ranking signal. Pages still on HTTP are marked Not secure by browsers.
What it is
This check flags URLs delivered without TLS encryption. Data travels in clear text and the browser shows a Not secure label.
Why it matters for SEO
Google has used HTTPS as a ranking signal for years, and Chrome warns users away from HTTP pages, which depresses click-through and conversions.
Example
http://example.com/contact (no TLS, browser shows: Not secure)
How to fix
- Install a valid TLS certificate (Let's Encrypt is free).
- Serve all pages over
https://. - Add a site-wide
301redirect from HTTP to HTTPS. - Update canonicals, sitemaps, and internal links to HTTPS.
