In order to increase traffic at their sites, poker sites pay affiliates to recruit people. In exchage, the affiliate gets a cut of the rake you pay. Affiliates, then, in an effort to recruit you, frequently pay you a portion of that rake back. The amount of rake you pay in a month is known as your monthly gross revenue, MGR, and your rakeback is computed against that. At most sites, any deposit bonuses you earn, though, counts against your MGR. For example, you pay $525 in rake one month @ 25% rake back, but you got a $100 reload bonus. Now, instead of getting $131 in rakeback, you only get $31. At Absolute, you get the full $131 in addition to your bonus. I might be off here and there in the details, but this is the gist of it.
