I really appreciate your knowledge , but the site has nothing to do with Panda as it got 300 pages with unique and  well written content

Keep in mind, too, that a lot of duplicate content is accidental. Google doesn't care about pages, per se - they care about unique URLs. So, if you have 300 unique pages, but something about your CMS translates that into 5,000 crawlable URLs, then you could definitely have problems.

I will appreciate if you will explain it bit more in details....

the site got only unique urls, by pages i meant urls too

The thing is that if you lost 90% of your traffic at the end of September (i.e. Sept 27/28) then the issue is very likely either EMD or Panda.  If you have a good site with 300 well written unique pages then in my mind EMD is almost impossible.  So, I would go investigating Panda issues. Duplicate and thin content are the top culprits but there can be other factors.

There are other possibilities though including a change in urls, DNS problems, hosting problems, malware issues, robots.txt problems, accidentally noindexing, a competitor ramping up their SEO etc. etc.

If the traffic drop was a little later, like October 5 then Penguin is a possibility.  Penguin is related to overoptimized anchor text in your backlinks among other things.

Sometimes when a site is affected on a Panda date but doesn't seem to have Panda issues it is possible that sites linking to your site were affected by Panda and as such you have lost some of your link juice.  But it is unlikely that 90% of your traffic would go because of this.

all top 10 positions were dropped in mid of november 2012.
I said 90 % ...i think the statment has been exaggerated....but  65% for sure

[MarieHaynes]

Ah!  I was thinking it was end of September because you said you were a casualty of EMD.  If this happened mid November then it's definitely not EMD.

There were Panda updates November 5 and November 21.  If the drop doesn't coincide with those dates then it is not due to a major algorithm change.  (By major I mean Panda/Penguin as Google is constantly tweaking the algorithm.)

But Panda...as far as know looking for duplicate content....and we are very careful with that for all our sites....Content is 100 unique and never been spinned, written by humans....

so i am confused more...

This is the article by M.Cutts I remeber i read it

date 3 october 2012....

after that day our site started to loose the trafic...not in 1 night but slowly..slowly...than
up to mid nov 2012 it lost about 65% ..this is why i have concluded from the begging that it was EMD

[Dr-Pete]

I have a post on the subject here - it's very long, because it's a complex subject:

We're not saying this is definitely the problem - just that you should be aware of how complicated it can get. Unfortunately, it's hard to tell without really looking at the site. A lot can happen to hurt a site's rankings, and the EMD update was just one piece of the puzzle.
