It depends on what your niche is - for example, if you have a finance site then 5c per click is very bad but if you have an adult site then 5c per click is pretty reasonable. You could certainly be doing much worse!
hmm im struggling 2 find a keyword which is $0.01/$0.02 per click, which is related direct to what my sites niche is
That's the main reason I go for AdEngage, I don't think targeting keywords will be beneficial for me. For you, you should try to play around with the keywords as much as possible.
yeh but if my adds show say buy ipod and the page they goto is about locksmiths they aint gonna click shit
