WHAT INTERACTION QUALIFIES AS A "VIEW"

With the new changes we now have a counter at the bottom left of a post showing how many people have viewed your post ...

What action (like - increasing reputation - opening the post - commenting) actually increases the amount of views.  I have done an experiment and opened - bought and liked it but it does not update the amount of views.

Can someone please help and clarify how do you increase the "views" of a post.  Thanks 🤗
