One of the skills issues with content curation is that you are driving users to someone else’s site. So if you share a specific post on social networks the user goes to their site not yours. Derric Haynie has a neat answer for this. He recommends you employ Rebrandly for link retargeting.
Rebrandly is a sophisticated URL shortener and whenever anybody clicks on a link set up via Rebrandly to visit any individual else’s site, they’re going to be added to your custom target audience as in the event that they had visited your individual. Thus which you can comprise this target market in your retargeted ads. Also if people clicked on the link from Twitter, that you would be able to run Twitter retargeting ads, if Facebook that you can run Facebook ads.
