The v7n blog has a good article that lists the top 10 SEO Mistakes.  Number 1 is a common mistake many new ecommerce site owners make-selecting keywords based on the search terms that will bring the most traffic rather than picking keywords that will bring the most targeted traffic.

The top 2:

Quote:1. No Marketing Plan - if you don’t know who your market is, and what they want, rankings will not help you. They’ll just help chew bandwidth and raise your opportunity cost.
2. Selecting Keyword Terms Based Only On Traffic Volume - you need to be number #1 for “cars”, because the term “cars” recieves a lot of search queries and you sell “cars”? That won’t do you a lot of good if you only sell cars in Fiji. See #1.
