Audience based on banner impressions
Is it possible to create a cookie or other audience based on banner impressions (on other sites that do not have our optimizely tag)? Can we, for instance, use Optimizely to show modified content to someone that has seen one of our banners on a 3rd party website without clicking on it, and later visits our site through a different medium? Basically, we want to target people that have seen our banner, doesn't click on it and visits our website later.
To see how to create one of these audiences, see:
