Frequently asked questions
Does SSL affect Google rankings?
Yes. Google confirmed HTTPS as a ranking signal in 2014. Sites without SSL may also show a "Not Secure" warning in Chrome, which significantly reduces trust and clicks.
What is HSTS?
HTTP Strict Transport Security (HSTS) is a header that tells browsers to always use HTTPS for your domain — even if a user types http://. It prevents downgrade attacks.
What is mixed content?
Mixed content occurs when an HTTPS page loads resources (images, scripts, CSS) over HTTP. Browsers block or warn about mixed content, which can break your site's appearance and security.
My SSL certificate is valid but the checker shows errors — why?
A valid certificate is just one part of SSL. You may still have issues with HTTP redirects not working, HSTS not configured, or mixed content on the page.
