I think there was another tweak today. My one Panda affected site moved back to page four from it's heady position at #2 on page 1 since 22nd March (prior to Panda it was at the top of page 2). My other sites continue to remain unaffected.
I think G did it's usual thing of opening it's filters before making a tweak and then closing them again.
I keep an eye on the stats of the larger content farms as it's easier to spot trends looking at large sites that you don't own :-) Take a look at this graph of Hubpages from quantcast (you will need to change the graph to US only to see what I mean).

There's a spike up around the 25th of March.
Quantcast also tracks the stats of Articlesbase, another site that got dinged by Panda. Curiously their stats show no spike:

Did some digging to see what the response of each of these two sites to Panda was.
Here's what Articlesbase did [blog.articlesbase.com]:
1) increase their detection of spun articles (they delete any they think are duplicates
2) increased the minimum word count to 350 from 250
3) stopped authors putting links at the top of the article, they can only place them in the author bio section, which remain no follow.
Hubpages have
taken a different approach [hubpages.com].
1) they changed their ad layout so there was no ad within the content
2) they required that intros to hubs should be text and image, no amazon, ebay or rss feeds right at the top.
3) they required hubbers to increase the text to make sure there was at least 50 words for every Amazon or ebay product featured.
4) they observed that hubs that had fallen back had rss news feeds and other feeds, and the active hubber population appear to have taken this to heart and gone on an rss deleting spree.
5) active hubbers also appear to be deleting any of their own hubs that appear to them to be weak, plus have gone on a rampage to root out spam on the site and report it (which hubpages deletes as soon as they can). The spam includes stuff that isn't duplicate, but just badly written and yucky.
I just thought peeps would be interested to see the differences, and to see how hubpages spiked when articles base didn't. So maybe with the filters temporarily lifted, they looked better to G than articles base?
Any comments?
