ELI5: how can some websites “trap” the user to their homepages when pressing the back button, but others take you right back to the search page.

There's an html element called a redirect; essentially if you make a page that immediately redirects you, your back button history will look like this, in descending order from most to least recent

* Current Site

* Site that redirects to Current Site

* Google

So if you *just* hit back, it takes you to the redirect site.

The trick is to double-click back so that it takes you back to Google through the redirect site, or in a more general sense, right click the back button and click google out of there.

Now, if you chain redirects in certain ways you can make it almost impossible to *just* click back. Some browsers have a built in "too many redirects" feature that will stop the browser after a certain number of redirects, but often they don't cover all the ways a redirect can occur, and the feature is most useful if you're working on your own site on the server-level, trying to get a redirect for a legitimate purpose, and not getting infinitely-recursive redirection due to an oopsie.
