  I have created new page and it's showing in Google Search Results for a week. After an week my page is not displaying in Google. ;
  
  How is this happening? What would be the reason?
  
  My Page, http://www.medindia.net/news/worlds-first-malaria-vaccine-to-be-rolled-out-to-children-in-sub-saharan-africa-154828-1.htm
  
  Please solve this issue...

  Juchel De Leon: in which way your searching for your page on the SERP?
• 
  Rajesh S: users entering the keyword which related to that page..
• 
  Juchel De Leon: what kind of keyword is that? you mind me asking :) thanks!
• 
  Rajesh S: I don't mind :) i couldn't find keywords for this page..not provided in GA
• 
  Juchel De Leon: are you trying to search the URL of the page? or your trying to search your page using a keyword?
• 
  Rajesh S: searching the URL of the page ..

  Rajesh S: sorry Juchel..i am trying to searching a page using keyword..

  Dave Elliott: Also can you break all your links please. Normally we make them (dot)net instead of .net etc

  Dave Elliott: To discourage spam posts we have a policy of not allowing users to link to thier own websites. Please change your links to http://www(dot)medindia(dot)net/news/worlds-first-malaria-vaccine-to-be-rolled-out-to-children-in-sub-saharan-africa-154828-1.htm
