Maybe more on ensuring the quality and being legitimate with site's content that Google gets strict in last update. Stealing content is discouraged..
The panda update is about making search result more relevant to the searchers by giving value to sites with original quality contents. Has rolled out in USA couple of month ago and finally to the rest of the world 11th of April. This will have a huge impact on search results, in USA over 11% search results had been affected by this Panda Update. Hope this will help
I saw a huge dive on my traffic in my Ezinearticles articles. I guess I will spend my time on other types of marketing instead.
Ezine is getting tougher on their submission guidelines and some other things in an attempt to revive themselves from the impact of the latest update. Can't say they didn't bring it upon themselves though... there had been a bunch of low quality stuff getting through, and people in general want a trustworthy source, and good content... not some blatantly ad infused, hard to read article directory with 300+ versions of the same article.
