Miamacs - Excellent post. We have been thinking the same way and found that when you start exploring how 'N' numbers and 'E' numbers would achieve this (as defined in the patient) the process is elegant, efficient and brilliantly simple. The one problem is the potential damage to innocent and comprehensive expert pages, but there are compensating factors that can pull a page back into the results. Basically, if it IS a really good page, other factors can kick in. We have been looking at Adwords data and concluded that it is a clue as to what data they have to work with, but comparing it with the content of pages that currently rank well could demonstrate that a lot of the suggested phrases are not a problem. Having said that, it all depends on the tolerances set and 'what phrase' actually triggers 'what phrase'. Gut instinct is often the decision maker and seems to works just as well!
