Search Targeting merges the power of search intent with the ability to repeatedly show your brand to people that have searched for your specific keywords or phrases. That's powerful Branding.
Search Targeting is similar to Retargeting because you only show a display advertisement to users after they have taken a specific action. In the case of Retargeting it is when the user has previously visited your website. With Search Retargeting a display advertisement is shown if the user has previously searched for a keyword or keyword phase that you have already requested.
Search Targeting is a highly effective way to target people who have proven to be interested in certain topics, and specific services and/or products based on their search history.
