Ever been to a website and then decide to leave only to find that you are being followed by its branding or ads on various other sites you visit. Well this is not some stroke of luck or even a case of a large advertising campaign. It's called remarketing and it's another step forward in Google's trend to personalise search marketing and advertising.
Remarketing works on building a list of prospects through an insertion of code onto your website. The code tracks prospects that have visited your site and places ad's on websites throughout Google's ad network. The user can then click on your ads and return to your landing page.
