There are so many options when it comes to automated bid management. Automated bid management: using scripts using conversion rate optimizer using enhanced CPC using 3rd party tools using adwords scripts using API – build your own This is our scenario. We manage PPC marketing (lead generation) for 100s of clients (local businesses). We want to automate as much as possible. Which one of the methods would be best to us. We would prefer to create our own inhouse solution using the API. However, I would like to understand the process (logic) of how that would work so that I can understand the algorithm (when we create our solution using the API).
I'm not sure if you will find your answer here. Give it a try in programming section. A developer or a programmer can help you in this. And am sure you can find solutions for this. I know few agencies who had such applications with them. If you want more details then do PM me.
