This is a really tricky question to answer but why don't you try once

Most of you here knows that when you search for something in google, you get two sets of results. One contains the ordinary web-page listings while another contains the sponsored web-page listings, which gives google employees their fat pay-checks

In my experience, I have found that most of the time clicking on the sponsored listings is of no use at all, because they hardly ever show me what I'm searching for. Their titles are misleading most of the time and so I have stopped even looking at them and go through the ordinary listings.
Then again, this might not be applicable for all the keywords. Sometimes the sposored listings could save you time and get you what you're looking for in an instant. It all depends onthe keyword. So how often do you click on these listings, knowing that you're profiting google?

Ever since I got bad results I stopped clicking on any ads at all, so google's been getting a loss of maybe few cents due to me! But when I'm, not getting what I'm looking for, why should I give profit to someone else? That's my argument.
I think I might as well add another question - do you think the sponsored listings are useful to
you? Not to google, but you! They will attract you and tempt you with their clever titles and in some cases flashy banners, but will you fall in the trap?!!!
