Work your way right to left then back and back and forth. Focusing on hitting a specific location of each pin (left side, middle, right side). Example, hitting the left side of the 7pin, then the center of the 7pin, the the right side of the 7pin which is the left side of the 4pin... and so on accross the rack. Being able to hit each pin at will in a specific location will increase your average quite alot. Just imagine how much improved your spare percentage will increase...in addition to split conversion. To perfect this skill, you must master your release and targeting. This in turn will increase your strike and pocket percentage which in turn will reduce the amount of potential spares leaves to single pins. You can see where I am going here.
