Microsoft’s Adcenter – Keyword Tools

AdCenter has an area to help you figure out the commercial intent of a word or website:
This tool can be used to find keywords that are commercial but have low ad coverage. From a SEM point of view, it is useful to find these keywords as they have low bid density (low price), but high commercial value. Similarly, for an advertizing engine, this can help increase ad relevancy by displaying fewer ads if a keyword has low online commercial intent.

Demographics Prediction
This tool predicts a user’s age, gender, and other demographic information, based on their online behavior, such as what queries they search online and what web sites they visit. It lets merchants learn more about their customers before bidding for keywords.
