A real step forward for e-marketing…
“Let’s say you’re a basketball team with tickets that you want to sell. You can put a piece of code on the tickets page of your website,which will let you later show relevant ticket ads (such as last minute discounts) to everyone who has visited that page,as they subsequently browse sites in the Google Content Network. In addition to your own site,you can also remarket to users who visited your YouTube brand channel or clicked your YouTube homepage ad.
You can also run a number of remarketing campaigns at the same time. For example,you could offer discount game tickets to users who’ve previously visited your tickets page,advertise VIP hospitality packages to users who clicked on your “How to get to the arena” page,and advertise a sale on team merchandise to users who previously visited your YouTube brand channel.

As we announced when we launched our beta of interest based advertising,we want to put users in control of the ads they see,so anyone can opt-out of remarketing by using the Ads Preferences Manager. Our remarketing product complies with industry standards developed by self-regulatory groups such as the NAI and IAB and IAB UK.”
