And they are serving up junk SERPS to lots of users and they know it. Why do they do that?

It's simple! They are using the same teaser trick that has worked for decades. We are almost all guilty of it on our sites. We give the user just enough to provide value to keep them on our site; trying to entice them to visit more pages on our site.

They are trying to increase time on page on Google Properties.
