MayDay Update, well, the only thing I am pleased about is, I inspired the naming of the update to MayDay, with credits to pontifex suggestion after my post and Tedster agreeing, see [webmasterworld.com ]. Secondly, it also shows WebmasterWorld's lead as the definite forum when it comes to tracking SEs activity.
From all observations I made since I last posted, ecommerce sites, sites with close to an even ratio (affiliate links/ unique content) and sites aggregating a fair bit of their content are hit harder. In short, sites having a considerable content originated first somewhere else are hit harder regardless of how much unique content is supporting the site.
Caffeine is not yet live, Gbot is still re-indexing larger sites from scratch as I noted weeks ago, HENCE many sites are still showing under-ranking due the latter fact, not enough indexed pages and pages linked to them are also being re-indexed = lower rank factor until all is re-indexed. When I pointed out what I called the Total-Recall, is basically a recount, re-index, re-rank...which shows the filters are only turned on again once all is done. So, there are a lot of changes yet to happen!
This algo update in the middle of moving to the new infrastructure did not help in anyway, we speculated and speculated and finally were sure it was an algo update, no thanks to anyone from G*, but thanks to all regulars here, we spotted it weeks before MC or VF confirmed that. If we can predict accurately as we did, then we can definitely also predict how to adapt to the new algo (once all is served from the caffeine IS and all sites are re-indexed and moved properly)!
