Google Indexing HTTPS
First it was mobile now it’s https. Google announced December 2015 that they will be indexing HTTPS by default going forward. That means GoogleBot will start crawling HTTPS equivalents of HTTP pages, even when the former are not linked to from any page. Many of our clients, including ourselves have already made the switch! If you haven’t done so, we highly encourage that you consider it.
At Google, user security has always been a top priority. Over the years, we’ve worked hard to promote a more secure web and to provide a better browsing experience for users Browsing the web should be a private experience between the user and the website. This is why they strongly promote HTTPS everywhere.
They will typically choose to index the HTTPS URL if:
- 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
