First of all this article was taken from Searchengineland.com Apr. 2, 2008 at 9:09am Eastern by Barry Schwartz.... I saw this and thought everyone might be interested... Google Update Dewey - Google Confirms Algorithm Change Remember a couple days ago I reported on some major shifts in the Google search results? Well, this morning I spotted Google's Matt Cutts requesting feedback on the change at WebmasterWorld. In short, Matt said he did not see "large differences in rankings between these datacenters," but he would like more feedback from the webmaster community. To submit feedback, he asked for webmasters to use this form and place the word "dewey" in the "Additional details" text area on that form. By doing so, they will review specific cases to this Google algorithm change and use that feedback to help improve the quality of the search results. So since Matt asked us to use the word "dewey," why not code name this Google update the "Dewey" update? It has been a while since we named a Google update, and this is the first major update we have seen in a while that has really been widely noticed. More details can be found at the Search Engine Roundtable. Interesting....
I doubt it's an actual algorithm change. Not only that, they're probably using the code word "Dewey" to separate the feedback they're requesting from the actual spam reports that get sent in.
If they did change their algorithms, then it'll be interesting to watch. I'm sure it won't affect me much since I put most of my focus on making sites for people, not search engines (I just let the search engines piggy-back on the hard work I'm doing for the people who use the sites I develop for my clients and friends).
yeah it seems heaps of people got hit by the latest algorith change... stay focused on quality content and baklinks and it should all be fine
