HTTPS as a ranking signal  |  Google Search Central Blog  |  Google for Developers (original) (raw)

Security is a top priority for Google. We invest a lot in making sure that our services use industry-leading security, likestrong HTTPS encryption by default. That means that people using Search, Gmail and Google Drive, for example, automatically have a secure connection to Google.

Beyond our own stuff, we're also working to make the Internet safer more broadly. A big part of that is making sure that websites people access from Google are secure. For instance, we have created resources to help webmastersprevent and fix security breaches on their sites.

We want to go even further. At Google I/O a few months ago, we called for"HTTPS everywhere" on the web.

We've also seen more and more webmasters adoptingHTTPS (also known as HTTP overTLS, or Transport Layer Security), on their website, which is encouraging.

For these reasons, over the past few months we've been running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. We've seen positive results, so we're starting to use HTTPS as a ranking signal. For now it's only a very lightweight signal—affecting fewer than 1% of global queries, and carrying less weight than other signals such ashigh-quality content —while we give webmasters time to switch to HTTPS. But over time, we may decide to strengthen it, because we'd like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.

In the coming weeks, we'll publish detailed best practices (it's in ourdocumentation now) to make TLS adoption easier, and to avoid common mistakes. Here are some basic tips to get started:

• Decide the kind of certificate you need: single, multi-domain, or wildcard certificate
• Use 2048-bit key certificates
• Use relative URLs for resources that reside on the same secure domain
• Use protocol relative URLs for all other domains
• Check out ourSite move article for more guidelines on how to change your website's address
• Don't block your HTTPS site from crawling using robots.txt
• Allow indexing of your pages by search engines where possible. Avoid the noindex robots meta tag.

If your website is already serving on HTTPS, you can test its security level and configuration with theQualys Lab tool. If you are concerned about TLS and your site's performance, have a look atIs TLS fast yet?. And of course, if you have any questions or concerns, please you can post in ourWebmaster Help Forums.

We hope to see more websites using HTTPS in the future. Let's all make the web more secure!
