For me it looks is a recalculation of link profiles. Looking at some queries that I have dropped, sites listing in top have stronger links, more of them buyed.
For some products they have large scale copied content, i have original hand written content and i am displayed lower in results.
It looks established sites has been advantaged (richest gets more and more, not surprise for me), but I don't understand the pressure from Google guys to make this change.
Running 4+ years old site, a lot of hours of work,add content and value, get links .. and now .. 29% drop traffic from US
I hope they will roll back some settings, i don't want to spend hard worked money buying links.
It is pretty demoralizing!
