Word of mouth is a powerful tool.

Last week I posted my “Big Red Fez homework” comments on the AIMS Discussion List (see below for BRF details). I included an Amazon.com associate link so that I could track the effectiveness of my recommendation.

Here is how we did in the three days after the posting was published:

1. ADL sent to 3200 AIMS members includes link to Godin book.

2. 49 people clicked on the link (5 people clicked more than once).

3. 21 people bought the book and downloaded it.

4. To date no one has sent me their homework.

That means I had a 1.7% clickthrough, and a 43% buy/browse ratio. Not bad I’d say. I made US$2.02 in referral fees by the way.
