Here's what we saw happen from Feb. 2 forward:
Brief background on the website:
This was for a travel/hotel website that's a little over 2 months old and uses API and XML-fed content. The site had approx. 700 backlinks and growing -- all organic and natural looking. The site as of now has about 58,000 pages recognized in Google from a "site:" search.
On Feb 2nd I noticed the Google referring traffic was down about 35%. On the 3rd, 4th, and till now (the 11th), the traffic has dropped around 90%+ for all XML supplied content pages. The only pages receiving traffic are our unique articles added to the guide section -- which is only around 30-40 so far. These pages are holding steady with traffic but all other pages are practically dead.
My 2 cents:
Websites with re-used XML or API-based content, especially mass amounts of it, are likely going to be hit in some way with this algo. update from Google. I have spoken two 3 other SEO guys since the 5th and all have reported this from one or more sites in their network of client or personal sites being managed. The exact same trend that our website experienced. Their websites had from 10,000 to 200,000 XML-fed pages but some other unique sections and content on certain parts of the website.
Since Blekko has already announced an out-right ban on websites like Buzzillions.com, Shopwiki.com, eHow.com, and others, many people are seeing this as a strong-arm PR move as a precursor to Google doing similar banning or demotions - although I would never expect Google will list the sites banned as they hardly ever call websites out in the same manner as Blekko did.
Our only silver lining - if you want to call it that - is that we only spent around 2 months on this hotel site versus it being 6 mos. or 12 mos.
