On another note, we recently went through this same process with an entire site redesign.  The executive team demanded we cut out over 75% of the pages on our site because they were useless to the visitor.  It's been 60 days since the launch of the new site and I've been able to still increase rankings, long-tail keywords, and even organic traffic.  It took a little bit of a "cowboy" mentality to get some simple things done (like using 301's instead of blocking the old content with robots.txt!).  I predicted we would lose a lot of our long tail keywords...but we haven't....yet!
In 2007, Google announced a campaign against paid links that transfer PageRank.[30] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat any nofollow links, in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[31] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated JavaScript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[32]
This post and the Skycraper technique changed my mind about how I approach SEO, I’m not a marketing expert and I haven’t ranked sites that monetize really well, I’m just a guy trying to get some projects moving on and I’m not even in the marketing business so I just wanted to say that the way you write makes the information accesible, even if you’re not a native english speaker as myself.
