I never understood using misleading or vague ads

It's not like you are paying per impression here. I don't see the sense in using flashy image banners or vague or sensationalist titles. Seems like you are throwing money away - wouldn't the objective be to make your topic as focused and uninteresting as possible so that only those with a genuine interest will visit your site?

I mean, you are going to get it shown regardless. Why do advertisers try to decieve people (slightly) in some adwords ads? Isn't that counter-productive?

All I'm asking is, does this train of logic make sense to you, or is there something I'm missing?

 

Targeted traffic is always better.

There are other reasons to grab any surfer out there.

They be playing a numbers game, hoping that enough if enough people see the site something will happen.

 

I believe some people use this method as a means to more significantly increase their CTR (obviously, to increase their position), then they revert back to their original creative.
