Yeah that;s true ,, Google changed his algo ,, As i have checked my traffic on analytic .. 100-130 organic traffic decreased since last week .. http://googleblog.blogspot.com/2011/02/finding-more-high-quality-sites-in.html
yeah, definitely. its confusing and it gives headache to most of us here...adjusting to its algo and optimizing the site without any clues what was the algo focusing on...
I am going to tell you all about the algorithm. its based on your onsite and content, especially your subpages that are not as accurate in quality as googles spider wish, they severed the flow of homepage authority to pages that lack googles standards. If traffic is down, work on your content, work on your subpages. I can honestly say, my ranking are as high as ever now.
My site didn't move in google up or down the last time I checked. After a year or so it isn't really doing the dance thing anymore. I honestly think that if you avoid spun content and doorway pages and other stuff like that and have unique content that these algo changes won't really hurt you. Or they shouldn't.
Google has launched content farm.. according to this, the site which have not good content or relevant content will be affected, those who have relevant and quality content they will be untouched.
As far as I know, it only affects USA based websites. Its not implemented worldwide yet.. Agree with SEOSAROJ though..
It's a world wide update by Google and yes seosaroj is right finally Google stop cramming link link and start to focus on highly relevant and unique content for batter search result display.
