Swing speed
Increasing club head speed is obviously going to create more distance.

Path (swing plane)
The shape the golf club takes around the body. Negative numbers means the golf club is coming more across the ball from an out to in swing path. The ideal swing path is square or 1, 2 or 3° from the inside. A tour swing will generally be in this range.

Upward path
This is the angle that the club comes into the golf ball. You don't want to be hitting down on the golf ball swinging a driver. Hitting down on the ball will make it pop up, cause mis-hits and lose ball speed and distance.

Face angle to path
The relationship the club face has to the direction of the path. If you want to hit the ball dead straight you want to get the club face numbers the same as the path. For instance, if the path is 0°, then you want the clubface to be the same. If the path is way outside or inside, you may want to club face to open or close to that path in order to bring the ball back to either the right or the left. If the ratio between the path and the face angle is great, then you're going to see a tremendous curvature of the golf ball. Therefore it's harder to control the ball flight.

Ball speed
Increased ball speed equals greater distance.

Center strike
Obviously you want to strike the ball more towards the center of the clubface. That's where the hotspot of the driver is. A center strike will improve accuracy and add distance.
