I am somewhat new to the world of PPC management and have been doing a lot of research on the issue. I recently posted a topic in the searchenginewatch forum in effort to learn what is the best PPC management pricing model. The topic has received a lot of very informative responses from all sorts of experts and novices. If I had to some up all the info learned from these numerous responses, I would give the summary that there is no particular “best” pricing model that will work “best” for every single client situation. It seems that the best price model would have to involve a combination of models.
