I've been experimenting with the google search on one of my sites. I figured why not I might make a few extra bucks with it. The first day I think I had like 17 clicks nothing major, but my other ads increased a lot. I thought nothing of it because price per click varies all the time. The next day I took it off my site (just to see if that was why my cpc increased) sand my ads seemed to be paying a lot less again. I put the search bar back on my site today and my revenue seems to be up 300% per click. This isn't anything major because I was averaging 2 cents but now I'm at like 8 cents average. This could just be a fluke I know but maybe someone else could try it and let me know how it goes?
