In terms of SEO, is it ok to have the same word in singular and plural in the URL? For example, I have a website to sell houses but I want to target for "house" and "houses", so if a person search "buy house" or "buy houses" my website can be in the results of Google.
So, is it ok to have a URL like
www.nicehouses.com/house/type1.html? Would Google process both terms? or will it be treated as spam? Is it a good idea to do this?
