Hang in there
PPC is an art form but thank goodness, it is an art that can be learned.
I'm getting more and more success with my PPC projects, I have had to be patient and not give up.
I have been happy to sit wherever my six or seven cents a click puts me as I learn how to write good ads and tweak them as I go. When I see that I'm really getting good at it, then I'll think about getting more bold with my bidding!
