Interestingly enough we have been hit hard with our ecommerce site, this is updated on a regular basis with new products being added daily and is clearly a valuable site.
Now none of the sites with this keyword in the domain rank on the first 2 pages.
This does not make sense at all as this has got rid of some legitimate sites.
I am currently de-optimising the website for this keyword on the pages to see what happens.
