Multiple domain redirecting to a single main domain


Suppose that I have 4 domains:,, and

The main website domain is so if I redirect all other domain to then is it good for SEO?

P.s. I don’t own any of the above domain, it’s just an example only.


You can do 301. There is no issues.


This Don’t affect SEO by a Bit.
If you really want to affect SEO by using these domains. Just make a Single page website using all domain and build some quality backlink to those single page website and than put a link of main website in those pages.
