Is it good for SEO if I have different domains pointing to pages on a website?

You mean to say if you added different domain links on one of your site page. It means that your single site gives one way backlink to other sites and it passes pr value from one site to different domains.

You mean, if you add another domain links on a page of your site. This means that your site does not provide a way to go to other sites and passes PR value from one site to different areas.

Can you please elaborate more?
