Lead Lizard did a little write up on what we're doing with Lead Scoring in Eloqua. It's pretty high-level as they didn't capture the finite details of the interview but it might be an interesting read. One disclaimer though - the article doesn't do a very good job of talking about how much of a team effort this was. So many people (most notably my boss Alex, my team mates Suzanne and Matthew and the whole Marketing Ops team) drove this effort and made it a success. I was just a member of the team.
Here's the article: http://www.leadlizard.com/mcafee-lead-scoring/
While you're at it, read the much more interesting interview with Meagen Eisenberg at Docusign: Why Lead Nurturing Matters in B2B Marketing - Lead Lizard | Lead Lizard. Docusign is one of the few organizations out there that I would say really have MA down to a science and with Meagan at the helm, it's no surprise.
Cheers!
