Google and the Longtail
SEO Book has given us a infographic about changes to Google's search algorithm that have made it less necessary to use "long tail keywords".
The term, long tail, refers to the data being statistically distributed largely in a long narrow band - rather than predominantly in a compressed range. Wikipedia notes that longtail has been popular in retail as the driving concept for selling unique items in low quantities. SRO marketers became skilled in identifying and using the "long tail keywords".
Google today is better at retreiving and ranking these long tail results. This infographic shows the changes in Google's search algorithms that have made this so. It is a fantastic summary.
