Nearly every site runs on HTTPS today, yet mixed content warnings and certificate issues still quietly undermine trust and performance.
Check for Mixed Content
Images, scripts, or embeds still loading over HTTP on an HTTPS page trigger browser warnings and can block resources entirely.
Watch Certificate Expiration
An expired certificate takes your entire site offline for visitors in the worst way — with a full-page security warning.
Confirm Redirects Are Clean
HTTP versions of your URLs should redirect directly to their HTTPS equivalent in a single hop, not bounce through several.
Next step: Use the Server Status Checker to confirm your redirects and server responses are behaving as expected.
