Web domain hurt seo?

[josh123]

does having the "web" prefix in the domain name, such as in web.pennies.com/copper hurt SEO?

Sanaa,

What that does is actually make for a new "sub" domain that is distinct from the pennies.com domain.  Depending on how closely tied a subdomain is with the root domain (via links and topics), the subdomain and pages within it all rank independently of the root domain.  There are wide variations in the degree of independence a subdomain has with the root but in answer to your question, it doesn't "hurt" SEO but it does require a different strategy to achieve desired results.  Here's some lit on the whole domain topic for you: http://moz.com/learn/seo/domain
