This week, we released category site selection for the site tool. This allows you to browse sites by category, making it easier for you to find and include sites that are relevant to your products or services. For example, if I want to advertise my soccer camp, I would first select the 'Browse Categories' button in the site tool. Then I can select 'Sports' and drilldown to the topic 'Soccer' in order to view sites that may interest me. It's a great new way to help you browse for sites that fit your needs, and we hope you'll check it out.
