I'm starting to investigate using remarketing for my website, in order to re-generate interest in customers who haven't converted.
My only issue is that i'm struggling to work out how to only target non-customers, as opposed to existing ones. (Website is a subscription based service in which many customers will log-in regualarly to use my tools).
Obviously my best bet is to visit GA & make some assumptions based on visitor interaction - as I don't hae a great deal of PPC data to go on.
Does anyone else have any better ideas on how to specifically target non-paying customers?
Thanks for any info shared in advance :)
