Geo tagging

Hello Dominic !

Am grateful for your support on my previous question. My site is running up very well with dwqa. However i have came across this geo tagging while doing seo for my questions. Few of my questions are localized and i want to add geo tags for it, which I dont find it anywhere in dwqa plugin

For example Best astrologer in Bangalore and Best astrologer in Chennai

I want to geo tag banaglore for first one and chennai geo tag for next. How can i do it ? Please explain

Thanks in advance for your reply
