When the system was originally implemented, it was indeed one area per day. But CipSoft later changed it to a 33% chance of a random area being improved, so it's, on average, one area every 3 days. The area is still random. This update also raised from 1kk to 10kk the amount of gold donated that is required to improve a specific area at the next server save. 

As for how it works: the spawn rate of the selected area will, generally, be doubled. I'm saying generally because if this combos with a Rapid Respawn event or boosted creature, it won't double but actually add 100% rate to the base spawn rate. For example:

Base rate: 1x
Improved area: 2x
Rapid Respawn: 5x
Rapid Respawn + Improved area: 7x
