Does site security affect how machines treat my site?
Security is about how safely your site is served: an encrypted connection that stays encrypted, and a clean Safe Browsing record. It matters to a machine because a machine that can't trust the connection or the content has every reason to leave the page out of what it shows people. Below are the 4 checks in this course, what each one looks for, and what good looks like. We read what your server sends from the outside; we can't audit what runs behind it.
All 4 checks count toward your headline score.

What good looks like Every script, style, frame, image and media file is referenced over https.
