Since I installed Expression Engine, I’ve been experiencing very strange search engine issues. At first my index got de-indexed because of the duplicate template url. Three days ago, Pagerank updated. It left me a little shocked because my site jumped to PR6, only to find out it had been mistaken for another website running Expression Engine. My backlinks have changed too, instead of showing relevant backlinks site:http://mysite.com now shows other Expression Engine sites which somehow seem to get counted as backlinks even though they don’t link to mine. At first I thought this was just a Google issue but it’s just too much of a coincidence that everything has to do with other Expression Engine sites. Does EE interlink all sites running Expression Engine?
