What links to put on the site?

Question

Search Engine Optimization

Good day!

I want to apologize in advance if I'm asking a stupid question. Not so long ago, I transferred the site from http to https protocol. Everything seems to be working fine. In .htaccess I registered a redirect to the main one with https.

Now the question itself: I still don’t understand, what backlinks to the site should I put, http or https?
And if you don't mind, could you explain a little more about how to do this? May need edits in .htaccess . Thank you!

UPD:
You misunderstood me. For example, I buy links on another site. This site links back to my site. What kind of link should be to my site. https or http? , assuming my site is https

Answer 1

natural

Answer 2

Use relative links wherever you can. Then there will be no problem with them.
