Key

• KW Difficulty - The score from SEOmoz's tool

• Top 3 OV Bids - The bid amount from the top 3 listings in Yahoo!'s PPC results

• Overture Monthly Predicted Traffic - The amount of traffic estimated via Overture for the previous month's data

• Wordtracker Monthly Predicted Traffic - The amount of traffic estimated via Wordtracker (note that you must add up all terms in their database that match and multiply by the number of days in the month - the "exact/precise search" function can help make this easier)

• Relevance Score - The % of searchers using this term/phrase that you feel are likely to be interested in your site's products/services/offerings. Although this is a subjective number, you can use conversion rates or click-through rates from previous campaigns to more accurately estimate this in the future.

In selecting final terms, those with lower difficulty, higher relevance and more traffic will offer the greatest value.
