JOHN MEULLER (Webmaster Analyst from Google):

So HTTPS has a lot of benefits, I think. And there are essentially three main things that come together with HTTPS. On the one hand, the user knows that they’re talking with that server directly. On the other hand, the content that’s sent back and forth between the user and the server is encrypted. So no third party can really listen in. And finally, because of all of this setup, the content that’s sent from the server is guaranteed to arrive at the user in that state. So it’s not modified. That last one is something that we sometimes see when you go to a public or an open WiFi hotspot where you’re browsing some random web page, and suddenly there are ads there that you didn’t recognize before. Some of these hotspots inject ads. Some of them inject tracking elements into those pages if they’re not on HTTPS. So these are the type of things that you, as a webmaster, might not want to have happen with your content. Additionally, it’s also something that’s de facto required for HTTP2. HTTP2 is a way of sending content in a really fast way. So it can bundle different pieces of content into one request and send that all at once. So that really speeds things up. And finally, if you’re using service workers, which is a technology that’s used by progressive web apps, particularly to facilitate offline websites- offline web apps- then those service workers also require HTTPS.
