HTTPS & Security Checker

Test your HTTPS set-up in one go: HTTP to HTTPS redirect, www consistency, TLS certificate and expiry, HSTS, security headers, mixed content and cookie flags, with copy-ready server rules.

A domain checks the home page; a full URL also checks that page for mixed content.

How to use the HTTPS & Security Checker

  1. 1

    Enter your domain or a page URL.

  2. 2

    Click Check security to test redirects, the certificate, headers and the page's resources.

  3. 3

    Copy the suggested .htaccess or Nginx rules and fix any failed checks.

Frequently asked questions

Is HTTPS a Google ranking factor?

Yes, a light one. More importantly, Chrome labels HTTP pages "Not secure", which hurts trust and conversions.

What is HSTS?

HTTP Strict Transport Security tells browsers to always use HTTPS for your site, so the first request can not be downgraded to HTTP.

What is mixed content?

An HTTPS page that loads scripts, styles, images or frames over http://. Browsers block or upgrade these files and may show a security warning.
