I was wondering whether anyone had found a really good site or book on PPC methodologies for ROI optimisation? I'm not really thinking from the copy writing or keyword identification angle but more in the sense on how to identify and group keywords e.g. by low, mid and high performance and then the tactics to take on each? So for the low performers to start converting, mid to move to high and high to convert at a lower CPA or higher ROAS - that type of thing.
We are currently using Atlas search to manage our campaigns so anything that takes into account paid search management and the rule setting that these technologies allow would be really helpful.
Anybody found anything like this online?
Cheers
Paul
