It bullshit from Google about quality and spam ! You can see on My profile i Have -1 ! I get -3 because i try to post on BHW example ... what crap spam page Google was displaying after EMD update ! Why then Google cannot recognize spam, but BHW can ? G lays about user experience, there is one big measurement for all pages AVG time on site if it is HIGH then page or website is Good !
From one Point i`m happy about all this stupid Updates ! If you give correct algorithm juice - you can get new website up in 1-3 weeks, normally it would take 1-2month hit 1 page !
In my ky word .... BING VS GOOGLE ! Bing have much more relevant pages then in Google !
