As I have come to realize in my job at Clickstop, SEO is job number 1. Without good SEO and SEM practices, it is hard to make money in eCommerce.
I came across this plugin called “SEO Tank Reporter”
Track your Google rankings every 3 days and see reports of your progress in an easy-to-read graph.
You pick the keywords you are looking for and then track that progress. This is a no non-sense way to track your progress, which will let you know how you are doing.
