When I started to understand the value of targeted traffic in its full potential in 2001, there were only a handful resources on the web to learn online marketing. Most of these resources were forums or membership sites you needed to sign up for and almost all of these were in English.
The most important source of information in 2002 for me was webmasterworld.com - a forum mostly for geeks and the technical savvy ones. Brett, the owner of the forum, was taking good care of the active posters on the forum and was running a little conference venue on the side which became Pubcon.com - an important yearly gathering of online marketeers and a great show to go beyond the small talk of SEO.
Since 2006 I am speaking on Pubcon every year, mostly about technical setups, server configurations and related topics. Pubcon happens twice a year and the "smaller" event is the one in spring. A good overview is here.
This year I am giving my 9th presentation on Pubcon and over the years I have met so many interesting and smart people there, that we have a special contest running right now: For participants in the US, we are giving away a ticket to pubcon, including a domestic flight and hotel stay. All you have to do to participate is sending a tweet.
Deadline is early September 2012. Join us for another great show this year.
