Seattle appears to be the chosen location for SMX Advanced Sessions which include an Expo. The first SMX Advanced session was in Seattle, June 2007. This year SMX Advanced returns June 3rd and 4th.
The Advanced SEO community are fluent in search marketing. People who attend generally want to talk to peers who can offer new ideas for improving search results.
