I'm setting up Adwords Remarketing - where users that click ads for a particular product but don't buy are served MORE ads later as they travel around the web.
We sell a variety of products, and have separate campaigns for each. I'd like to show ads pertaining to specific campaigns to those users. I'd have to do a different code snippet for each campaign.
Users searching for Widgets should see widget ads. Users searching for other products should see those relevant ads.
Is there a way that I can munge the code together for several campaigns and place that chunk of code site wide? I've tried to do some kind of JS if/then = document.write tricks, but nothing seems to be working correctly.
