Also, as far as I'm aware there are only three ways to gain points to level up. You may not be doing them:
Win games
Maintain a high place in a ladder (or finish high in the seasonal ladder)
Unlock achievements
As a general rule if you don't win games, no matter how many you play, you won't level up fast.
But since the only way to really improve this is watching games and practising you'd be doing the correct thing by playing lots of games.
But, as Fizzer said - if you have an ad-blocker running all of this is next to useless.
