Maybe 'cause you "run into" the ads in the content network. The User was not specifically looking for you... He just found you...
What strategies could you recommend with the Content network?
Thanks!
It is not necessarily that certain products are more effective, it's more that certain strategies need to be applied. In general, I think you want to use the content network for maximum exposure and brand building, so it is best to bid CPM.
Advantages
- you can target trademarks and competitor names more stealthy.
- long tail keywords that produce "low search volume" can still get impressions on the content network
- you can target human readable phrases more easily
Disadvantages
- broad scope phrases are ineffective
- negative keywords are very important
- lots of junk websites using ad sense
- increased chance of click fraud
