Point the shoulder toward the ball

The shoulder turn occurs on a tilted plane, so the left shoulder should move down as well as around on the backswing.

If you’ve properly tilted and turned your shoulders going back, your left shoulder should point toward the ball at the top of the swing. This backswing turn will put you in the right position to strike the ball squarely and forcefully.

Many average golfers, especially those who have played baseball, turn their shoulders on too much of a level plane. Rotation like this makes the swing too flat and limits your chances of hitting the ball with a square clubface.
