How to check a site for mixed content and SSL warnings

Mixed content and bad certificates break trust in the browser. Run a website inspection that lists TLS and http:// assets on https:// pages in one report.

Visitors see a lock warning or blocked image long before they open a support ticket. Mixed content is an http:// script, image, or font on an https:// page. SSL warnings are certificate problems on the host you typed. Catch both with one inspection, then watch expiry continuously on the URLs that matter.

One-off inspection

Run SiteCheck on the public HTTPS URL. The report includes TLS-related checks and mixed content alongside broken links and SEO basics. Free: up to 25 pages, no account, no card. Details of each finding: what a website health report covers.

Fix order:

  1. Certificate valid for every hostname that answers (apex and www if both are used).
  2. Replace or proxy http:// active content (scripts, stylesheets) first — browsers block those.
  3. Then images and fonts still loaded over HTTP.

Continuous certificate watch

An inspection is a point in time. Certificates still expire later. Put the important public URLs on SignalWatch; the same monitor alerts when the cert is inside 14 days (again at 3 days), and when the page goes down. Free: 3 monitors. Walkthrough: how to monitor TLS certificate expiry.

What SiteCheck is not

  • A full desktop SSL laboratory (cipher audits, CAA deep-dives).
  • A CDN configuration panel. It reports what the public crawl sees.

Checklist

  • Inspect production HTTPS URL after any host or CDN change.
  • Fix mixed active content before launch marketing starts.
  • SignalWatch on the apex (and www if separate certs) for expiry alerts.
