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 pic.twitter.com/eHgUc5YoCQ

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. pic.twitter.com/OHWbUNlIL9
