Hi everyone! I'm new here and really excited about getting going with this. I have a question about domain names and forwarding them to another site. I'm thinking about creating a website, but just doing it as an extension of an existing one, such as
www.blahblahblah.com/product and then getting a domain name that redirects to it. My question is, will I get the benefit from an SEO standpoint of having a domain name with my keywords in it? Or would I be better off from an SEO standpoint to just get new hosting and making this new site from scratch?
Hopefully my question makes sense, it's late and so I'm not sure if I'm being clear

Thanks to anyone who can help me out!
