Well Overstock and JCpenny are not on that list... so black hat link buying is not a factor for this update. (IMO)
I am all screwed up because the content scrapers argument seems to be the most enticing idea in the forums... yet, there are so many sites that are content scrapers ranking ahead of us with our content (or copied content from the MFG).
Seems like a lot of OLD websites... so maybe it has to do something with the "old" coding on our old sites? I for one have been "scared" to change much on our site over the years for fear of screwing something up for the G bot.
Did anybody catch, is this list: https://spreadsheets.google.com/pub?hl=en&hl=en&key=0AnIg_DeUJWYCdEpkY2EzamV1MktFd0ltZ2VsZGQtcmc&single=true&gid=0&output=html all of the websites that were negatively affected or just the most negatively affected? And if they are the "most" negatively affected it is it a complete list or is this just a sampling? As hard as it is to take today's reality, if our site is only one of 300 it doesn't seem like that much collateral damage and probably a relatively easy thing for Google to sweep under the rug.
