Don't have an exact answer to the right code to use in design, but can't you use your language mbox parameter as filtering condition in audience and qualify different users based on the language to different design experiences (you will have to setup Recommendations as an offer in XT activity). 

Hi @LordOfTheRings ,  There definitely isn't the dynamic option you are looking for in the criteria filters (at least for now). If the number of offers is limited and manageable manually then you could try using static filters in the criteria sequence (of course you will have to come up with a prefe...

Hi,  You might want to create a criteria sequence where each criteria has a filtering condition to look into the pool of similar items, then apply "limit the number of items" to 1 for each criteria. In that way every criteria will return only a single product.    Let us know if that works. 

Hi @LordOfTheRings ,  Have you setup A4T through server side logging or client side logging in Analytics? Refer to this document for more details of either setup: https://experienceleague.adobe.com/docs/experience-platform/edge/personalization/adobe-target/a4t/overview.html?lang=en  

Hi @jpetermarias1 ,  Can you clarify a few things in the question: You mentioned the activity type was XT. In that case how is the "All Visitors" audience setup in the activity?How is each audience split into Default Content Vs Modified Content since we are talking about XT activity? I am making my ...

With "New Visitors" condition you might miss those who are not new to the site but haven't seen the experience before either because they didn't navigate to the page or the activity wasn't live by then.  One other option you could try is to pass a custom code from within the Target experience to pas...

Are you signing in my any chance on the site to capture mbox3rdParty id?  If yes, you will continue to see the same experience. If not once you clear cookies then you will be treated as a new visitor and what @Gaurav_Singh mentioned holds true.

Hi @jean-philippe_8 ,  The logic sounds fine. One thing you could check is the time range you have provided. If you wanted to check for within the last 30 days you might want to change time frame condition to something like below:  The time frame you selected might be checking for beyond one month....

@guruanand,  1. You don't have to parameterize URLs for rendering different personalized variations. Setup different experiences in Target and it will take care of splitting the audiences and rendering different experiences to the different audiences. You are using the same URL as an end user. 2. Ch...

Thank you @DisaRas for your response. Had followed the steps you mentioned. Had to raise a clientcare ticket and there seems to be some caching issue on the site I was trying to render the personalization. Now it is working for me as well.
