I just say I should give Googel AdWords a try and result was excellent. Google AdWords increased my sales threefold. I hadly get traffic to my site and hardly makes sales and life was painful; untill I used Google Adwords. Now I can go to the best restaurants and eat whatever I want. The secrete is that AdWords let you chose your target population; maybe country or region and send your Add to that people. Since they are interested in what you are doing, they are likely to click on your Add and check you out. Thanks Google AdWords!
It's good to hear a success story, the majority of the threads here are negative so that was a nice change.
Really Google Adwords is unbeaten by other Ad networks like Yahoo and MSN. I am SEM specialist I tried lots of Ad Networks for advertising but Google Adwords and eSpot Media are excellent revenue generated Ad Networks because both are using same technology to serve Ad to publisher even eSpot Media is much better in revenue generation while Google Adword is best in UI.
