Do people recommend PPC management services? Our ad spend exceeds $15,000 monthly. Most of key terms are not changing. I see so much written on seo but little written about PPC management. How does one find a reputable firm? Since our terms do not seem to change much (altho we have about 100 core terms and another 400-600 terms that generate small traffic). About 10 terms generate 80% of our traffic.

Would we be best off just buying our own bid management sofware. Or do the ppc management companies pay for themselves even though our terms do not change that frequently.

Which bid management software works best? Is go toast worth the high monthly lease (you cannot buy it)?
