Welcome to the Q&A Forum

Behind what you describe is "google suggest" - it`s the same thing that auto completes your search queries (if you want). I am afraid to tell you that you cant control what other users will see under "people also search for"... well of course there is an indirect option by being the one who is (one of) the most visited studios (I mean by clicks not by real visits). Of course this doesnt work just by clicking on your links as much as possible... just be likeable for potential visitors and the numbers will grow. And as these numbers grow, you will have a very big chance to be mentioned there. If you use chrome you can (try to) turn of google suggest by unchecking the box for this feature under the settings menu (privacy).
