Keywords & Phrases
Most commonly keyword targeting and reporting will be used in combination with a search function on your web site. This enables you to serve relevant ads on your search results page. However, if you choose to purchase the contextual add-on module, you can enjoy using keyword and phrase targeting on all pages of your site without doing any integration work as the contextual module will automatically spider all pages containing ads on your web site.
