Hi I'm trying to compare a couple AdWords audit & automation services (start & mid-level solutions - not enterprise): - WordStream - bidcops - adwordsrobot - optmyzr - karooya - omp-tools - any other? Do you use any of them? Why? Could you please highlight strong and weak sides of them and share any relevant experience? What tools are most useful? I will really appreciate for all the answers, thank you!
