Hi Guys After adhering to the On Page optimisation suggestions given by SEOmoz, we redirected some of old urls to new ones.  We set 301 redirects from the old pages to new on a page by page basis but our search engine ranking subsequently fell off the radar and lost PR. We confirmed redirection with fiddler and it shows 301 permanent redirect on every page as expected. To manage redirection using a common code logic we executed following: In Http module, using “rewrite path” we route “all old page requests” to a page called “redirect.aspx? oldpagename =[oldpagename]”.  This happens at server side. In redirect.aspx we are redirecting from old page to new page using 301 permanent redirect. In the browser, when old page is requested, it will 301 redirect to new page. In hope we and others can learn from our mistakes - what did we do wrong ?!? Thanks in advance. Dave - www.paysubsonline.com
