I am creating experience using OOTB target audience "Referred from Google". For testing the mbox offers, what parameter should I pass with mbox so that it respond with matching offers for "Referred from Google".
To simulate the behaviour from the webpage for a not yet live website, you can create an Audience within Adobe Target "Referred From Google- Not Live" and add rule for Traffic sources and place condition as Referring Landing Page contains say " www.localhost.com/google_dummy_search_page" .
What type of Activity you are creating i.e. AB Testing or Multivariate or Experience Targeting as different different activities have different use cases ?.
If you want to create an offer for Audiences "Referred From Google" Then in that case , you can use Experience Targeting and there will be 1:1 mapping between the Experience and Audience and it will not be required to pass a separate mbox parameter.
Please do let us know in case of any more questions or queries.
