Hi Skanda
Thanks for your reply.
First of all this plugin is outdated, secondly it does not solve my query. 
What I want to add is in area between <head> and </head>. and the code is 
<meta name=”geo.region” content=”IN-CH” />
<meta name=”geo.placename” content=”Chandigarh” />
<meta name=”geo.position” content=”30.718865;76.74439″ />
<meta name=”ICBM” content=”30.718865, 76.74439″ />
The plugin does not provide any such feature to add it. 
Kindly solve the issue. 
Regards
Vikas
