Customer churn and Retention

In any business competitors are always looking to grab your customers, and many customers are on the lookout for a better deal. Customer attrition rates range from 7% to 40% annually in various industries. Slowing this customer "churn" rate by as little as 1% can add millions of dollars to any sizable company's bottom line.

My reply to Avinash Kaushik comment on how useless web analytis reports are
