Retargeting, or remarketing, is a way to follow your audience across the web and target them with appropriate ads and messaging. By placing a pixel (a small piece of code) on your website, you're able to track visitors and continue marketing to them in other places. 

We especially love this article, from Moz, which describes retargeting in greater detail.

'It's a form of marketing in which you target users who have previously visited your website with banners ads on display networks across the web.'
