Hi @kkchaitu - just read your question and would need further information to ensure I got it correct.
I believe you are trying to show the same content across multiple pages. Now, are you trying to assess the performance of the content alone i.e. irrespective of the page OR the performance of content + page combination?
Second question: Are you also comparing the performance of personalised experiences against the default experience (running A/B test) Or simply using Experience Targeting (XT) activities for each new page?
If you are using XT, there could be two options:
1. Performance of the content alone: In this case, all you need to do is just extend the page-template rule to add all the page-URLs (in case of VEC). @Gokul_Agiwal provided a link for it in his response. If you are using Form-based-composer then extend the audience-definition under Audience Refinement section. This would mean you will have a single experience in the activity for each content-variation.
2. Performance of content + page combinations: In this case, you will create Audiences for each page in the same activity and copy the content. This would mean you will have multiple experiences in your activity (but still only one activity).
If you are using AB test, then you can use Multiple Audiences feature within VEC to show the same content on multiple pages:

Hope this helps,
