Do you really want a High Earning Affiliate Program? Well, Infolink is what you are looking for. It’s cool that they are text ads, meaning, it doesn’t matter (a particular substance) what niche your blog is into. You can Monetize (convert into or express in the form of currency) Your Blog Without Jeopardising (put at risk of loss, harm, or failure) Your Theme! Aside from that, they give you other opportunities (a favourable time or set of circumstances for doing something) to earn money from referral. A chance to earn $20 USD on referral.
For the past couple of months I've earned about $20 a month with TLA and last month I used Social Spark for the first time and earned another $20 a month with them.
I tried lots of stuff, but the only thing that proved useful and usable is Adsense, they are the best in terms of variety and quantity. They will never run out of ads no matter what your niche is or where you live, and they pay good and on time.
