Is Buying Domains Good For SEO? Can I 301 redirect domains to an Original website?

[TSpike1]

I have a friend that purchased multiple domains related to their website. Each of these domains have the back ground of the original website and irrelevant content on them. Is is possible to redirect the various domains to certain pages on the original website. For example if the website is www.shoes.com and they purchased domains such as www.leathermensshoes.com and a few others related to the website. Is it SEO friendly to link the domains purchased to the original website?

Hi TS pike1, I would not suggest that - because if u are pointing the other Domains to the related content on your "original website page" u will end up having duplicate content 4 that page!

I suggest to setup your other domains like www.leatherrmenschoes.com and rely target on this page (put relevant content!!)  - then u can put some links to your main page - or even if this other domain is getting strong you could redirect it later 301 to your man project! Harry t.

To clarify, the domain name of these purchased domains is relevant to the main domain, but the content on the pages is not? So the domain might be leathermensshoes but the content is about umbrellas, or am I totally misunderstanding?

What if there isn't any content on the redirected domain? Would there be any reason to, or reason not to, forward a blank domain that is only relevant because of that actual domain name?

Still using shoes: I have 2 domains, SHOES.COM and DESIGNER.COM. Shoes.com is where I sell shoes. Designer.com is the name of the shoe designer. There isn't any content on Designer.com, but it's the name of my shoe designer...so it's relevant to shoes.com. Should I forward the domain to Shoes.com?

How many times is it OK to do this before taking an SEO hit?
