Off site SEO includes things like link building and social interaction. Website credibility issues like public relations and branding also play a big roll in off site optimization.
  • Do people know who you are well enough to search for you?
  • Do they trust you enough to buy from you?
  • Have you built good will through community participation?
  • What makes your site remarkable enough for others to talk about?
  • Do you give people marketable advice that they want to share with others?
Many on site things you do also play a role in your off site optimization. For example, many people will link to your best content by using its page title and/or official name in the link, and many people will link to your site with your domain name or site name in the anchor text.
