Hi, I would like to play on content network I know only bid price is lower than search network. I can run but how to success? Ad Text style? How many keyword? CTR? Please advice...
It's not him in particular, it's the whole AdSense system (aka the Content Network). Click fraud is rampant throughout it. But some people do have success advertising on it.
Maybe it varies from country to country, but I've had some very good results in the UK with the Content Network - I always test it, and end up using it on about half of all the campaigns that I manage...
