I'm advertising with G, Yah and Adc. and I am excited about their assistance and help, and even more my bottom line. Cost are less, increasing number of CTR as a ratio, compared with the other two, and I even received a call for free evaluation and consultation how to improve keywords and ad writing. Imagine this, a live person spent 35 minutes on the phone who knows his stuff. try this with G or yah. I'm shifting more and more to Adc. of my $$
Actually I got this from Yahoo too. Which was great. But it was at beginning of my advertising. They impressed me with their service. Google are a bit slower with their help, but if you insist long enough you have a chance to get an answer sooner than the promised 24 hours.
