I agree - there has been some other major update rolling out this week, but it was before today's Panda iteration.

Well Google deindexed a major blog network on the 19th.

Here's the post from the network concerned confirming that it all happened on March 19th, and that they are closing their doors:

[buildmyrank.com...]

I understand they had about 25,000 sites each with about 1000-2000 posts all with links going out to various sites on the web. That's millions of links lost in aggregate (at least 25 million assuming each post had one link).

I think it takes about 4-7 days for the SERPs to recalculate when links are lost, so the timing is rather cute - the recalculation due to link loss will be hitting at the same time as the Panda refresh and peeps will be rushing around wondering whether their ranking loss is down to Panda or down to links (or maybe both!)

I've seen gains, but I think it's purely down to my competitors being knobbled rather than anything to do with my sites.

I think G is focusing on links this year, and it's kind of exciting.
