Sadly, Google is using false logic with this update. An assumption has been made that because a website is heavily optimised for a particular search term then it isn't worthy of occupying a high position but this is not necessarily the case. The majority of highly professional sites have been subjected to highly professional SEO in the past, and are now facing possible demotion because of this. A lot of sites (including some of mine) which have had little or no optimisation have risen but there is a good reason why many of these sites were never promoted - they are simply not good enough to justify it. Nevertheless they now occupy higher positions than their quality justifies.
A classic case of throwing the baby out with the bathwater.
