Dave, I do not go on all this incredible research you do involving keywords or whatever else you do.
I go by results as do my members - results only. It either does or does not perform well.
If a source does not perform well they are history. If they do perform well then we keep 'em.
Outside of that absolutely nothing else matters - only results.
Unless your personally tracking every lead that is distributed to all of your members and really monitoring all results,(Bogus Leads) Disqualified, Bad #, having a few agents telling you they are doing well is not a viable tool to measure results. If you were buying the leads and providing them to your members, I think you would have a different spin on what is a successful Lead Vendor. It would go deeper than a few skilled agents having success.
