Google to Start to Prioritize Indexing of HTTPS Pages

Zineb Ait Bahajji from Google announced that moving forward, Google will start to prioritize their indexing of web pages based on HTTPS vs HTTP URLs.

Although Google indexing seems to prefer the HTTPS version by default, you can also make this clearer for other search engines by redirecting your HTTP site to your HTTPS version and by implementing the HSTS header on your server.

Direct from Google’s mouth: “Today we’d like to announce that we’re adjusting our indexing system to look for more HTTPS pages… Specifically, we’ll start crawling HTTPS equivalents of HTTP pages, even when the former are not linked to from any page… When two URLs from the same domain appear to have the same content but are served over different protocol schemes, we’ll typically choose to index the HTTPS URL.”

Some of the conditions:

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 sitemap lists the HTTPS URL or doesn’t list the HTTP version of the URL.
The server has a valid TLS certificate.

The first condition is a big one, that the page doesn’t include “insecure dependencies.” Many pages include insecure images, includes, embeds, videos and so on.
