Google showing different links in SERPs

[tomstarrry]

Google search results are showing my site links in both URLs, "example.com" and "https://example.com". However the one with https is showing a favicon, and the other one is not. So i wanna keep the https one and delete the other one. I went to GSC to submit "example.com" for removal and it said that URL will be deleted in ALL of its variations. So how do i delete the "example.com" links? Should i just index the ones with https again? Would that work?

When you write "example.com" do you mean http://example.com? If so, what happens when you go to http://example.com are you redirected to https?

Well, I've just deleted a long paragraph about setting your preferred domain in GSC (with/without www, http vs https) because it turns out they no longer have [developers.google.com] this setting. Instead as Nick said above they simply go by your 301s. So make sure the four possible forms are all redirected to the one you prefer.

In case you are tempted to take the ControlPanel shortcut, keep in mind that it defaults to a 302 (temporary) redirect. There are a LOT of older threads around in the Apache forum here and a few that might help are at: [webmasterworld.com...] and another to change for https is here: [webmasterworld.com...]

The https example there would deal with requests for sites that DO use www, but it can be adapted to use non-www. domains as well. There are many examples for both/either need. This is called the canonicalization rewrite and there is not one that is perfect for all.

A search here will turn up thousands of examples. Reading helps you sort through - or you can ask for help if it doesn't go as expected.

Without knowing whether you're using WP I only advise that it should be the last rewrite rule in sequence for your rewrite rules unless you are using WordPress - then the WP rewrite snippet goes at the end.

[phranque]

assuming Apache web server, use mod_rewrite directives to implement 301 redirects for http: requests to the corresponding canonical https: urls.

I have been using .htaccess for such things and Google accepts it just fine.
