The Chrome mixed content change, does it affect your site's Googlebot rendering? Probably not! If your site has moved to HTTPS and you the gray lock icon in Chrome when viewing pages, you're all set. Woot! No need to be insecure if your website is secure! #happyemoji
If you moved to HTTPS and Chrome doesn't show a gray lock icon, there's mixed content. Mixed content is when a HTTPS page includes HTTP content, like an image or a video loading from HTTP. Upcoming changes may break the page for users & Googlebot. (developers.google.com/web/fundamenta…)
How do you fix mixed content? Make sure all of your site's resources are moved to HTTPS, including all images, videos, stylesheets, scripts, etc. Unsure which URL it is? Use Chrome's Developer Tools to find out more. Update the embedded URLs, sometimes it's a small change.
