>Demand Media: "at this point in time, we haven’t seen a material net impact on our Content & Media business."
" by mid-April, with the full suite of Panda updates in place, Demand was feeling the pain. As of April 16, it accounted for only 0.34 percent of Google’s downstream, a 40 percent decline from the start of 2011.
Some individual Demand sites are doing even worse than that, with Answerbag, a questions-and-answers site, being the hardest hit. Its Google referrals are down 80 percent. Meanwhile, eHow, Demand’s largest and most important site by far, is down 29 percent; it now accounts for 0.29 percent of Google’s downstream."
"Other content farms have taken it on the chin as well. Mahalo’s Google traffic is down 78 percent, Associate Content’s is down 61 percent and Examiner.com is down 51 percent."
