What about Partner affiliate providers?
Recently, Google began partnering with multiple tech companies for a broader reach in many areas. Including the creation of a partner affiliate network with local services ads. These providers do not receive Local Services Ads leads through Google, but through the partner affiliate’s platform directly.
Currently, Google Partner affiliates (US) for Local Ad Services are:
Thumbtack and Networx
