Making your website secure, will now mean more business.

Google will now try to index https (SSL secure sites) before http pages giving this a boost on sites that are secure.

The new conditions include:

• It doesn’t contain insecure dependencies.
• It isn’t blocked from crawling by robots.txt.
• It doesn’t redirect users to or through an insecure HTTP page.
• It doesn’t have a rel= “canonical” link to the HTTP page.
• It doesn’t contain a noindex robots meta tag.
• It doesn’t have on-host outlinks to HTTP URLs.
• The sitemaps lists the HTTPS URL, or doesn’t list the HTTP version of the URL.
• The server has a valid TLS certificate.
