Google in a recent post on Google+, announced that they are extending the reach of Remarketing Lists for search ads (RLSA) to Google search partner traffic.
“Search partners extend the reach of search ads to hundreds of non-Google websites, as well as Google Video and other Google websites. This change means your audience-targeted bids, keywords, and ads will reach more of your potential customers without any additional work. To take advantage, just ensure your RLSA campaigns are opted in to “include search partners” in your campaign settings.”
