Stay with Townsquare Interactive if
Stay with Townsquare Interactive if the account team is the product. Website, listings, reputation, social and email under one roof with one person to call is a real service, and splitting it up to save money can cost you more in coordination than it saves in fees.
Stay if you are advertising with a local radio station in the same group and the two are working together. Media relationships are worth protecting, and a website vendor is not a reason to disturb one.
