I am having issue with ranking of keyword of my site which i think might be related to Meta description. I have noticed that for my site aamindia.com the serp results have vanished from google and for some some keywords it is showing totally different page with random meta description. For eg : If i search 'delhi jal board duplicate bill' on google.co.in it is showing the result http://www.aamindia.com/bill-payment/online-electricity-bill-payment/page/2/ some where in 40-50th position. Instead of showing the page http://www.aamindia.com/delhi-jal-board-duplicate-bill/ which was till now coming in top 10. Now the Meta description of the other page is kind of wrong plus if anyone can help me with sudden drop in rankings. Is it because of this meta description issue?
Can this be because of my theme?
