Question about AdSonar for publishers

Hi guys, I’m planning to switch to AdSonar (from AdEngage) since I’m not generating that much revenue. I only got 24 cents within 2 months. Probably because not all my visitors are interested with the ads (they’re not related to my content).
My questions about AdSonar are:
– Do they require a minimum amount of traffic?
– Do they payout?
– Do they count clicks from visitors all over the world (not just US/Canada)?
Thanks in advance,
Je
