Scroll down to "Contributor Value and Levels"

From the FAQ

What are levels, and how can I increase my level?
Levels range from 0-10, with level 0 being the default after registration, and level 10 being the highest level attainable. Levels represent a user's contributions to the community. At their core, they are calculated based on a user's contributor value. When a user creates a giveaway that's received by the winner, their contributor value and level increases. This allows the user to access additional giveaways that are restricted to higher levels. If you mouseover your level in the navigation bar, or the level on your user profile, you'll see a tooltip with the level rounded to 2 decimal places. This will give you a better idea of small increments in level, and when you're about to level up.
Levels increase in difficulty almost exponentially. Below is a summary of levels and their corresponding contributor values.
Level 0: $0.00
Level 1: $0.01 - $25
Level 2: $25 - $50
Level 3: $50 - $100
Level 4: $100 - $250
Level 5: $250 - $500
Level 6: $500 - $1,000
Level 7: $1,000 - $2,000
Level 8: $2,000 - $3,000
Level 9: $3,000 - $5,000
Level 10: $5,000+

tl;dr: give away more games.

Give away games that haven't been given away for free.
If a game has 2 * next to it when choosing which game it has been given away for free and won't give you Contributor Value. (for example Why So Evil)
