It is very easy for our clients using retargeting solutions to get more leads and sales after they've visited our site.
Also we're able to track where their customers went once you bring them back to your website or app through retargeting. We don't have any dislikes at this time, but I'm sure there are many people who would like to see some changes made in terms of design/user experience. So far it's been very simple to use and has helped us with getting more traffic from different sources (social media).
