Google Update on 17-Jan-2013?????

I am not sure about changing Google algorithm but I had also seen some rapid drop down in SERP on 17th Evening.
I am very confuse about this need some confirm answer if anyone have.

 

I have found the rank of my blog has decreased, and I don't know why.

 

Even, My website Eye Universal has dropped for the targeted keywords website design San Diego and website development San Diego. Google has not announced any news yet and still dropped the sites from the index.

 

My problem is differ When i search with my domain name - in result not display home page in first page all Backlink page from Social site like linkdin, wordpress and all.

Please tell me if any updates

 

But Google completely decline that they updated their algorithm but mostly SEOs website keywords went down due to this update.

whew all my rankings on page 1 and page drops but i build quality links maybe changes is been applied by google or any google problems that hits everyone.

 

Definitely something is happened because mu website keywords also went down.

 

It makes sense for sites meant to be for India or UK, not to show up in Google.com and of course they should rank better than other sites in Google.in and Google.co.uk. If such sites were getting more traffic before, it was because their sites were showing up in Google.com results by mistake. People in US do go to Google.com and whenever they are searching, they are searching for results meant for American people and not the British or Indian people. It is just a personal feedback and I think Google has done the right thing by doing so.

 

I checked by sites some keywords goes up and some goes down from 2 page to 7 page.

 

Finally confirmed google update on 22 jan named as google panda update version 24. you can see more details on searchengineland.

 

I have lost ranking of my website http://www.myguesthouse.com/guest-houses-in-new-delhi.html because of this update? or anything else?
