Google, who in 2014 announced that it considered HTTPS to be a lightweight ranking factor affecting less than 1% of global queries, has increased the importance it places on HTTPS. Google now displays a “not secure” message in Chrome for users who find themselves on an unencrypted page.
HTTPS, which stands for HyperText Transfer Protocol Secure, protects the transfer of information between your browser and server from “man in the middle” attacks.
Because users appreciate seeing the lock icon in the address bar when using your site, HTTPS reduces bounce rate and improves dwell time, which are both good news for your business and for SEO.
