Profile suggestions

Hi
Does anyone know how are the suggestions based on when you click on that arrow next to the follow button?

That would be helpful to know
Thank you in advance

It may suggest according name, category and bio in my opinion.

Hi! In my opinion, though, the suggestions when you click on the arrow next to the follow button is based on the accounts related to the account you intend to follow and also they're based on the people that you will potentially follow based on the accounts you already are following.
