I am just going to name a handful of the conference coming up that relate to this industry. I am sorry if I leave any out.
SEO Roadshow - September 18th at 12 noon - London This seems to be a pretty exclusive get together, where only 'invited' people can attend. "This ain't no agenda kind of gig! All we have is free admission, free bar and no "sponsors" to spoil the fun."
High Rankings Search Engine Marketing Seminar - September 23 & 24 - Boston This event, to my understanding, is tailored for people who need to learn SEO with personal attention. This is a small seminar, with some excellent speakers. They are also accepting registration just for the dinner, Thursday night.
Search Engine Strategies - October 27 & 28 - Stockholm, Sweden This is the grand daddy of all search engine conferences. SES conferences take place several times a year throughout the US and the rest of the world. I expect the Sweden event to be pretty small compared to the others. These conferences are more about learning, network building and exhibitors. I hope to attend this one, always wanted to visit Sweden, but who knows.
WebmasterWorld's Conference - November 16, 17, 18 - Las Vegas, Nevada Not as large as most the SES conferences, but they are expecting 1,500-2500 attendees for this upcoming event. I will be attending and covering this conference at this blog. Never been to Vegas, so it should be fun.
