We need to knock this change out of the park since it's an algo change and not a human evaluation. I'm seeing tons of new spam (multiple sub domain abuse) in the rankings I follow.
If you have a site that has seen significant traffic loss I'd like to know the following (and I'll answer too with one site that got hammered).
# does the site have affiliate links? answer: yes
# if yes, how many per page? answer: 15
# if yes, is nofollow used? answer: yes
# does the site repeat verbatim title and descriptions of products as worded on the affiliate site? answer: yes
# if yes does the site offer any unique content to improve the "stock" product information? answer: yes (reviews)
# is the site a thin affiliate site? answer: no
# does the site, if it is an affiliate site, have a better than 50/50 ratio of non affiliate pages? answer: yes
other questions need to be added, I'd love to see a form created to gather data from a wide range of webmasters to spot the culprit more quickly. We're dealing with an average of a change per day so we NEED to pick up the speed on figuring them out.
I have a feeling that sites who offer products for sale AND have an affiliate program are seeing their traffic increase from long tail, the algo change might be to remove the middleman. I don't have enough data to conclude that just yet.
