Is there a good reason to stay with content-related ads? Is there a benefit to the 12000 impressions producing 9 clicks? It wouldn't seem like I'm missing anything by leaving them, but is it good to have all those fruitless impressions?
My keywords are very specifically targetted. This site doesn't sell widgets or blue widgets. It's more like fuschia anykindofwidget -- ie the universe of consumer products but targeted to an uncommon part of supply chain. So, if I don't target very narrowly, presumably my ads show up in front of useless eyeballs.
The largest question really is: Does my terrible performance in content-related clicks tell me something about my campaign as a whole, or should I accept that content-related doesn't work for me?
When I first used Adwords I purposely put the price of the item in the ad to stop freebie hunters and junk traffic. I would get something like 1000 impressions per day and only 10 clicks. Out of the 10 clicks though one, or more, would buy. Google soon disabled my ads though. I pleaded my case a few times via email only to be basically told "Like it or lump it" :o(
This is the only drawback I see with Adwords as compared to other PPC advertizing.
