Boost Your APM in Starcraft 2
APM stands for actions per minute. An action is anything from clicking a worker to using an ability. Pro players can easily break 100.

Basically it is just the way to measure a players speed in the game. To play good you need to be very fast as the game progresses and you have more tasks to perform. You should be focusing on making smart moves the entire game but also you should focus on increasing your APM. Follow these tips to do so.
Do a warm up. When the game starts out and you send your workers to mine you should just spam the actions by clicking your workers and hitting the keys back and forth as fast as you can to get a feel for what will be ahead.
Know the hot keys of your race. Of course you should be setting your control groups but also make sure you know all the shortcuts for abilities, training a unit, and building a structure.
Always be hitting keys. You should constantly be in the game just checking over everything and moving around a lot. This game is all about who can out play the other guy.
Keep up with production. While you are controlling your army to be effective in battle you should be hitting the hot keys to select your production buildings and keep training more units while attacking your opponent.

It can be really tough to get fast but after a while of playing and getting a good feel for it everything will become second nature. Practice makes for perfection so strive for it if you want to be a really good player.

Basically as you keep building more buildings and including them into your hot keys you should be going around selecting each building and making sure that you are keeping up with production.

Even when you think everything is under control you need to be checking over everything. Constantly be producing workers at your bases. Constantly be producing units at your production buildings. Scout every few minutes so you know what is going on.

Do all of this macro stuff while sending over units to harass them. Throw curve balls at them to make it difficult for them to multitask.

This is what playing the game is all about. Keep hitting those keys like a mad man. Have as much control over the game as you can with your speed and you will become a force to be reckoned with.
