What this checks

Mixed content is what remains after an HTTPS migration that missed a few hardcoded URLs. Browsers block or warn on it, which can silently break images, stylesheets and scripts while the page still appears to load.

  • Every http:// reference in src or href
  • Total count
  • The specific URLs

How to act on the result

  • Change hardcoded http:// URLs to https:// or protocol-relative.
  • In a database-driven site this usually needs a search and replace across content.
  • Third-party embeds that only support HTTP need replacing.

Frequently asked

What is mixed content?

Insecure http:// resources loaded by a secure https:// page. Browsers block active content such as scripts outright, and warn on passive content such as images.

Does it affect SEO?

Indirectly. Blocked scripts and stylesheets can break rendering, and Google renders pages when indexing. A broken render is an SEO problem.

How do I find it on a large site?

Browser console reports it per page. For a whole site, a crawl is the practical approach. This tool checks a single page at a time.

Are protocol-relative URLs a good fix?

They work, but plain https:// is clearer and there is no longer any reason to support HTTP.
