I would like to know if it is necessary, to avoid Google penalties and chrome warnings, by enabled HTTPS on a website that does not have a login page or a form.
In some cases the website can have a search field form that is needed just to enter a search term.
I think it's overkill to put a lock on a house that doesn't contain jewelery. And besides, locks take longer to open than knobs because of the extra turn required for the key.There are other important reasons for website encryption besides personal information. Governments and ISPs shouldn't be able to log every URL that gets requested over a monitored network. Nobody should be able to insert ads into pages without the user and the site knowing it. Webmasters should be able to know that their content isn't altered before it reaches users.
