How to respond to Buyer Requests?


I was getting good numbers of orders my gig is mostly on page 1 and 2 and these days my orders have decreased. I have also used Buyer requests section and sent many offers but i rarely get any orders from buyer requests page.

Am i doing something wrong in sending offers. Please tell me what is the correct way to send offers.

I would like to add that these days buyer requests are very less.
