Angular site deployment

Hi guys hope you all are doing well..

I need your help or suggestion...on Angular deployment.

Actually my website is created using angular and also i have created blog in my website...

And both have different build type like for blog we have used build Ssr for server side rendering and second is for production build.

So my question is should i deploy blog on different domain or on same domain...

For ex:- Website.com Blog.website.com

Or should i have same domain for both.. Which is good..
