Know which side to serve from
When your score is even, you have to serve from the right side of the court. On the other hand, you have to change sides when your score is odd. Moreover, serve diagonally towards your opponent.
Use underhand while serving
It is ideal to use an underhand technique while serving, especially if you are in a process of learning the game. This way, you will be able to avoid making mistakes and your opponent will be unable to counter attack aggressively.
Hold the racket firmly
Take a firm grip on the racket, as that will help you get control over things easily. You can shorten the grip on the handle, if you are not feeling comfortable. Once you are into a rhythm, you can again get back to your normal position.
Keep the racket upside down
Continue rotating the racket until it is upside down. This way, you will manage to hit the shuttlecock from the centre of your racket and generate more power.
Hold the shuttlecock from the edge
Other than positioning the racket in the correct way, you have to hold the shuttlecock correctly as well. Make sure, you have only grabbed it from the edge, so that you can easily release it when going for the serve.
Move your racket forward
Move and hold your racket forward, so that you can go for the serve comfortably. You have to stay in that position for a few seconds before going for the serve.
Focus and serve
Focus on the top of the net and go for the serve. It is ideal not to go for a forceful serve, if you are a starter.
