SEOMoz have updated their search engine ranking factors compilation which they publish every 2 years. We think this is essential reading for everyone in digital marketing, not just SEO specialists since it shows how to best get success in SEO and what to target your agency on. In 2009 the top 5 ranking factors were:
- Keyword focussed anchor text from external links
- External link popularity
- Diversity of external link sources
- Keyword use anywhere in title tags
- Trustworthiness of Domain based on Link Distance from Trusted Domains

- The overall value of external links has shrunk (though new fields have been added which may skew data)
- Domain level brand metrics are introduced as a key factor'
