Jaya,
I just skimmed your blog thru !!
Looks interesting to an extent !!
Here are certain tips to improvize :
1) You certainly got to improve your language if you have to set the bar above standards
2) In order to increase traffic, start writing stuffs that might captivate a wider range of audience ; when you write something about medical stuffs, your audience range is limited naturally.
3) Keep publisicing your blog on a regular basis. Facebook and twitter are powerful tools.
4) Find the source as to where majority traffic comes from and start working on it to improve the traffic
Thanks
