You don't put your website here on these pages. This is the website lol. Your website is your collection of Hubs about unique content silly. Each Hub can be a "Page" in a sense. All the pages meet at your profile (acts as a homepage). Some content you write on here can be linked to your personal site if its related. Linking more then twice to the same source in a hub is frowned down upon and can be labeled overly promotional and be flagged for revision. Failure to revise and resubmit could end in termination of your account.
