Because Google Cash Detective is so dang expensive, what if a mastermind group or marketing team pulled their resources together and shared a single GCD account on a timeshare/group marketing basis?
If it really is as good as it claims to be, a team working together could likely achieve greater results than most individuals alone, with much less financial risk.
Set up a simple contract of agreement of how the group will share or have access to info., charge $50-$100 upfront to join the team (depending on group size 5-10 people) then $15/mo. via PayPal, then work together on campaigns to grow.
Sharing GCD could be by time periods during the day or perhaps group members each get to send 3-5 requests a day for info on a product or keyword or another metric, and the team leader sends out the most profitable campaigns to team members according to their requests. There are several ways to skin that cat, and I am sure you savvy ones get the idea.
If you already have GCD this would be an easy way for you to leverage the tool and others' efforts/ideas to recover much of the cost. If you don't already have GCD, start a team.
This can be done with really any product. I am sure a good team working together can achieve more than one working alone. All the best to any who run with this platinum idea.
Oh! By the way, I mentioned "free" because if anyone appreciates this and would like me to help contribute to their team, please PM me, and I would greatly appreciate a spot on the team to help grow and share the wealth. And I have much more to offer...
