Retargeting: Each platform offers retargeting to help you reach people who’ve already visited your website. The benefit of retargeting is that a conversion is more likely when you know the prospect is interested. You might also upload an email list and use Facebook Custom Audiences to serve ads directly to subscribers. In the following example, we see two ads that show in the Facebook sidebar to reach former web visitors.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
