One of the hidden stones you immediately hit while moving web sites from one platform to another is the numerous links that search systems store momentarily become obsolete. Of course there are ways to make old links point to same places but sometimes the construct like http://aquashieldonline.com/cgi-bin/order_form.cfm ?step=2 doesn’t really make any sense anymore… So what you do (especially if you moved from ColdFusion to PHP) is you just make all old links point to the first page and be content… for some time, until you discover that since old links don’t work and new links didn’t propagate yet the site is almost invisible in search engines like Yahoo, Google, MSN and so on…
