Automattic announced that they’re launching free HTTPS for all custom domains hosted on WordPress.com. WordPress.com has supported encryption for WordPress.com subdomains since 2014, but now it’s being expanded to over a million custom domains.

The company says users will see secure encryption automatically deployed on every new site within minutes.

“We are closing the door to un-encrypted web traffic (HTTP) at every opportunity,” writes Automattic’s Chief Systems Wrangler.

As he notes, encryption provides more than security.

“Protocol enhancements like SPDY and HTTP/2 have narrowed the performance gap between encrypted and un-encrypted web traffic, with encrypted HTTP/2 outperforming un-encrypted HTTP/1.1 in some cases,” he writes.

Google announced HTTPS as a ranking signal in 2014. Back in December, the search engine started indexing HTTPS versions of URLs by default.

Earlier this year, Moz found that HTTPS URLs made up 25% of page-one Google results across 10,000 queries.
