How to optimize user transitions on the site?

Question

JavaScript

Hello. I have a question. How can you optimize the transition of the user, for example, by pressing the menu buttons or somewhere else?
I know that this can be done with Ajax (content loading), but are there any other ways?
And how, in general, does uploading work better than hyperlinks?

Answer 1

links are better for a
bot, again, better,
but ajax is better for mobile
