Many of our adCenter blog posts refer to a free tool we offer called the adCenter Add-in Beta for Excel 2007. I wanted to call this tool out specifically, in case you are not familiar with it -- the Add-in can help you expand your keyword lists and plan your keyword strategy. Features available in the tool include:

• Keyword Extraction: extract a list of popular keywords from a specified Web site.
• Keyword Suggestion: generate a list of relevant keywords based on a list you provide.
• Monthly Traffic: obtain monthly historical and future forecasted impression counts for keywords to gauge popularity and guide your keyword investment.
• Keyword Monetization: learn about clicks, impressions, position, click through rate, cost per click, and match type for a given time period.
• Search Buzz: Top Spiky Keywords (seasonality and spikes in popularity) and Top Frequent Keywords (trends for popular keywords).
• Demographic: provides demographic information about the given keywords within a set time period. The percentage (shown as a decimal) of searches by gender and age group are shown in the output.
• Geographic: learn location information and impression info by location to help with geographic targeting.

Be sure to check out the five step-by-step Add-in tutorials, and visit the Excel Add In page on the Microsoft Advertising site to download the Add-in and review the product guide, installation guide, FAQ and features list.
