Getting Credit for OEM 3rd Party Leads
by Daniel Boismier about Last Year

I am looking for shortcuts from other's learnings about submitting for lead credit for OEM 3rd party leads. I am most interested in knowing if anyone is having success (and the secret) with the following;

Nissan Third Party
Infiniti Third Party
GM Third Part
Subaru ILM
Ford Direct

Any insight would be appreciated. Thanks.
