Which programs are the best alternatives to Google AdSense?

I am waiting for approval from Google AdSense on my websites. But, if Google doesn't approve me, which programs are the best alternatives?

-- additional information --
[Website 1] age: 1 month, visits/month: 3.5k (facebook)
[Website 2] age: 2.5 years, visits/month: 4k (google ads)
[Website 3] age: 10 months, visits/month: 1k- (google organic)

Mediavine , which is used by almost big websites has launched a new program which allows publishers with 10k sessions only (15-18k visits). check journeymv(dot)com . That should be your target imho.
