SEO consultants and experts always trigger “fog-salesman” alert in my head. I had my share of grudge with various people promising to my clients quick rise of rating on search engine reports, easy inclusion of 500 different search engines etc. Anil Dash showed that there is nothing that can replace good content. Write good content, and people will link to you. Have dispersed links, and you will be placed higher.
Additionally, mark that content to be semantically correct. You will certainly have lighter code and SE will find it easier to index your pages. We all knew this by heart or believed that this is the case. However, I recently got a confirmation of this.
