a. Why are old dated websites ranking with old content so good ?
b. Why are scrapers thriving ?
c. Why are websites regularly updated being hit?
To me it all looks like "Content STICKINESS" , I wont go into details but seems like that hits the nail right where it's supposed - the flaw of panda. Forget about content quality(It's for the users, not panda).
Just brief overview :
a. Content is already established
b. Temporary gains nullifies original and scraper
c. Content can not stick, not enough original exposure
This topped with authority ranks(don't get me started there), shady(slow mo) caching,unpredictable unannounced updates , and miss info has lead to this tragedy with such an easy solution.
I am certain if you go deep into this points you will find the light in the tunnel.
I will try and give more details on the way out of the tunnel !
P.S. there is a SERPs update coming as usual .
