If you already advertise on Google, all you need to do is add a piece of Google remarketing code, also known as a tag or pixel, to your website so that visitors can get added to your remarketing audiences through browser cookies. You can customize the code for different pages to correspond to more defined categories.

For example, let’s say you operate an e-commerce business that sells kitchen supples. You might create a “toaster” remarketing audience based on people who visit the pages of your site where you sell toasters. That way, you can show these specific visitors highly targeted display ads that market your toasters. You already know they are in-market for toasters, and now you can draw them back, perhaps with a special offer like “free shipping.”
