Hello Everyone,
Matt Cutts has announced that Panda rolling out on 15th to 18th March 2013.So ready for this.
Always exciting with new updates. Good luck to all :)
(Although, I think this and future Penguin updates will probably mostly target new link networks, and most people should by now know not to start using such)
It will effect ecommerce sites in march update.
I didn't see any effect on my site, so I think, my site is working fine.
