This article aims to provide a few tips on what to look for and what to ask, in the early stages of the RFP.
Are you limited to one track/bid management tool?
Many PPC agencies utilize a 3rd party or in-house technology solution which manages your campaign performance if they are limited to one solution. Then is that solution right for your model??
Can you provide case studies on your performance?
Obviously this data is confidential, but they should be able to provide "ballpark" figures and percentages to allow them to prove how successful they are. You will need to look at their performance since taking on the campaign so ask for a before and after snapshot to access the impact.
What differentiates you from the others?
This is probably the most important question of them all, with a large number of PPC agencies competing for your business, why are they different? Expect some "marketing" fluff in this reply, but look between the lines, an agency should be passionate and dedicated to their clients and offer something unique.
