It is called advertising. It peaks your interest and gets you to click on the link to give you more information.
Kinda like how everything in priced with .99 or .98. It makes you think you are getting it for less.
"Oh, look that is only 9.98."
They teach you that kind of thing in Marketing classes in college. ALL businesses do it.
Businesses = make money = success
Businesses = make no money = failure
