I have a client whom I reshape the website for. It will become a community website while it is now more of an organization website (informative). For every member we’ll be providing a subdomain (user.site.eg), and not very much content will be left on the actual domain (site.eg). I warned my client that having subdomain will make the site look very content-poor for searchengines (it will be seen as a lot of separate sites) and so it will become low-ranked, but my client believes that because the ranking currently is very good, that won’t happen…
Is the subdomain thing really such a bad idea like I believe it is?
Or if we crosslink much (user to user, domain to user and user to domain), will that do the trick or any good?
