Remarketing for Search Ads is a new Google AdWords feature that works similarly to typical remarketing keyword bidding but shows up as Google search page results, writes Andrew Goodman. The feature could revitalize keyword search campaigns that aren't quite making their numbers by permitting much finer retargeting control. For example, a keyword that's getting too much attention from tire kickers to be worth it could be made to go into action only when shoppers are checking out on your site, Goodman writes.
