After Google Confirms HTTPS as a factor for ranking a site. We know the importance of HTTPS (SSL Certificate) to encrypt blog connections. Blogger users were very excited after Google blogger officially rolled out this feature for Blogs.

What are mixed Content Errors that appear on browsers?

When a blog/website is enabled for https. When a user opened that blog/site then the webpage will download initial HTML content securely over HTTPS then load the follow up content  (such as  images, videos, stylesheets, scripts) over insecure HTTP one by one from top to bottom if in that follow up content any script or image which starts with http will consider as mixed content. This trigger Browser error to display and degrade the HTTPS security and effects badly user experience of your blog/website.

Mixed content can be caused by HTML markup External Stylesheets or JavaScript content in:
  • Blogger Blog Templates Source
  • Post and page source
  • Third Party Gadgets source
