To date I have started four ad groups with Google Adwords. Only one of the four is successful with both clicks and conversions. The other three were failures for various reasons. Here is a post-mortem on one of these failures.
Canon 20D Camera
I picked this because it had a higher sticker price and I wanted to try and sell something through buy.com. I had 897 impressions and 0 clicks! The average page position was 10.8. I was only willing to pay 0.15 cents a click.
Thoughts:
1. Buy.com doesn’t have a great price on this camera
2. Lots of competition
3. The 20D has high search engine traffic and I was afraid to spend more per click for a better page position (visions of spending a ton of money with no conversions danced in my head)
4. I varied my ad texts but nothing pulled a click
I am convinced that Adwords is viable with the right product/commission scheme/click price. I’m still searching for that perfect mix.
