How can I make use of audiences created in audience stream in RTP (Marketo's personalization tool) to customize user behavior and show relevant campaigns as per their visitor profiles setup in audience stream?
I am sure anyone could have used AS to personalize site behavrior.
Apologies I am not too familiar with Marketo's RTP tool, but can Marketo access local storage?
Using Data Layer enrichment (https://community.tealiumiq.com/t5/Universal-Data-Hub/Data-Layer-Enrichment/ta-p/684) you could use Audience Stream attributes, audiences and badges to personalise the experience.
This information will be available in local storage on your site, providing Data Layer Enrichment is turned on.
I hope this helps!
