I think this update has completely killed the domain trader industry.
Why?
Because Google has basically penalised ALL sites using an EMD which havn't built up enough size/age/links.
If you develop an EMD now it seems you will be indefinitely penalised site-wide until you're big enough, regardless of your content quality or site. Even if you can afford to wait for the penalty to lift until you're big enough, there's no telling when that will be or if the time will ever come.
You could literally have put the same site on non-EMD and be ranking fine, yet because you used an EMD you are being targeted as spam. It's not just a query dependant devaluation of rankings, it's a full blown site penalty.
I have a site that's extremely high quality, domain is relevant to the niche (and actually a brand) yet it looks fucked:
StudentMoney.co.uk
The exacts "student money" doesn't even get any searches. I bought the name for brand value, not seo ranking.
Seriously, develop a site on a keyword domain at your own will now.
