Is there any Google Algorithm Update? 20% Traffic Decreased!

Is there any Google Penguin or Panda update recently? i need to confirm!

 

After 24th Panda Update rolled out on 22nd January'2013, no update is there.

 

Thanks for the confirmation but what problem could it be?

 

Hi I hope you find this useful but you can keep abreast of recent updates on the link below:

Nothing that I am aware of but google kind of unstable these days.

 

I am following SEL, SEOMOZ, SERT and SEJ.I have not seen any one notified similar stuff.I think its may be a google dance effect or you have to check in your webmaster messages.

 

Thank you guys (y)

 

Google has no updates after 22nd January panda updation in which he penalized site for the duplicate content.It is based on 1.3% content matching.
