By far, the best tactical oriented presentation I saw at shop.org was the Advanced Search: Part Art, Part Science – The SEO Secrets Most Agencies Won’t Reveal given primarily by Stephan Spencer, President of Netconcepts with the help of Elaine Wu of Victoria’s Secret, and Steve Spangler of SteveSpanglerScience.com.  Stephan walked through the presentation sharing tools and tactics for improving ranking on organic search sites.  The tools and tactics were broken up into 3 main areas, Technical Optimization, Content Optimization, and Link Building.  Below are the ones I thought were most interesting.

Grouped Google Results:  On Google you’ll often see that there are grouped results when it’s two links from the same domain.  The interesting thing to note is that the secondary link in the grouping is not neccesarily ranked at that position in the search results.  It could really be the 9th or 10th position on the page but its moved up by google to improve the search experience.  As an example, if the search results come back for a keyword you are interested in and has the first link going to somesite1, the second link going to somesite2, third link which is indented also going to somesite2, and then the following 7 links going to various other sites. 

A tactic here is to search google with the keyword and append &num=9 or append &num=8 which will only show 9 or 8 results per page respectively.  Do this until you see the second link dissappear and that will tell you want position that link should have come in at. 

Once you know this, you can specifically optimize your page or some one elses page that is ranked one or two lower to get above them and basically kick it off the page. 

Essential Tools:  Another informative part of the presentation was the tools he uses and recommends for optimizing your site.
