I have been using adwords for marketing my websites for more than a year and I have paid lot of money to Google. I have been studying the clicks and the sites from where the click were coming and found some disappointing facts.
Most of the clicks came from sites which are just made for adsense revenue or Made for Adsense websites (MFA). I fear the authenticity of the clicks. Paying per click for such kind of traffic is not worth, thats what I feel and I have decided not use Adwords for some time until google does something for this.
Lots of news are read that Google cancelled many accounts for fraud clicks and they refund the money to the advertiser. I have hardly go any refund , may be less than 0.25% of what I have spend.
If you are an Google adwords users, please track the clicks and check the conversions.
Hope Google does something for this:)
