Todd Van Hoosear and Chuck Tanowitz  use the magic formula above to measure influence.

Important point: Todd reminds us that social media influence does not reflect real time influence.

The Four Rs of Influence
In identifying and prioritizing reporters, bloggers, editors, analysts, etc., we measure influence through a proprietary mix of four primary factors, what we call The Four Rs:

1. Reach. How many people see this person’s content, not just directly, but through other influencers and sharing?
2. Relevance. How relevant is the person to your organization’s community?
3. Reputation. What’s this person’s reputation with your community?
4. Receptivity. The counterbalance that affects how much energy we expend to influence any particular influencer: how receptive will this person be to our outreach and key messages?
