Shortly after I published my article "What's the Competition Doing?, resources and advice for ethically gathering business intelligence about your competitors", I received an email from another author pointing out her tutorial on the same subject.

Debbie Flanagan has written a free tutorial on "Researching Companies Online". It is well designed, well written and contains some different links than I used. Take a look and compare. I welcome your feedback, and I'm sure Debbie does too.
