Excluding Existing Customers From Display Retargeting
We are running display retargeting off the blog section of our website, however we have found that 60% of the traffic to these pages are existing customers. As our product is a service, we ideally want to exclude these existing customers from our acquisition led display. We run a regular customer enewsletter which is set up with utm tracking. Is there anyway in which we can use this tracking to build an audience to exclude from display?
Many thanks
