The title and the cover. The title got my attention, but if it cover photo is a bad quality photography of a random thing, no one is that keen to figure out what the rest of the story is about. Everything needs to catch your eye when you post something I guess. The amount you made on it can also sometimes tell you it's a good quality post since a lot of people seemed to think so, but there are some hidden good quality posts out there.

Thanks for the answer. :)
