Drastic fall in Google.com search visitors from US

During last 3-4 days, I have experienced a drastic fall in the number of US visitors from google.com search results. However, the visitors from other country-specific google search domains such as uk, in, remains more or less the same. Are others also facing similar problems? Is there any problem with google.com US servers?

 

Google i updating it's algorithm every day, so you may have been affected by the latest PR/Algorithm update.
Just check if you have links coming from "bad neighbourhoods".

 

Thanksgiving. It's a very big deal in the USA. A lot of people will probably have left work early on Friday to get together with family, etc. It's the "long weekend". Things will return to normal soon, so don't worry.

 

Google made a change around Nov 17.. for many webmasters there has been a 20%-30% drop.. many other webmaster forums are all abuzz about it.. it seems for some the traffic is creeping back up today.. a little..

An analysis someone did last year of traffic drop and holiday times, including the traffic drop for 2010 and 2011 thanksgiving.

 

I'm sure this is the case for many, but this does not explain the cliff-drop on Nov 17 that many of us are reporting. We arent talking about a gradual decrease over a few days - we are talking about a 20%-30% drop, overnight.

 

What we are talking about looks more like this.
This is 2011 (orange) compared to 2012 (blue).. the big drop in blue was Nov 17. Notice that 2011 was steady..

 

I felt no change till now

 

I wouldn't quite call that a cliff drop, but sharper than 2011. Do (or did) you get a fair amount of traffic from Google images? Is the above all traffic or just USA traffic from Google.com?

 

Well take that as a natural issue since you know there are always ups and down for keywords ranking in Google.

 

I'm never faceing this kind of problem, I think its a bug and Google also agree that his search engines contain a lot of bugs in last 6 months. That's why many reputed websites loses their ranking as well as a lot of black hat techniques are die.

 

i dont get a lot of image traffic.. the graph is only Google traffic from all counties, but the majority is from U.S.A.

 

Did your ranks actually change for your main keywords?

 

If we set USA as geographic target on google webmaster tools, we will get more activity from US users ?
