When I first started internet marketing I was trying to build a list to send affiliate offers to and I only made nickels and dimes which never covered my cost of clicks to build my list. Then one day I bought a WSO for $9 on how to make and sell whiteboard video scribes on Fiverr. Well, I crushed it and brought in $11,880 in 8 months by working on the side. I was hooked and my new best friend was PayPal That money catapulted me to the next level as I used the proceeds to build my list which is now responsive to my offers. I still do Fiverr but have turned it down as my time is now worth more.
With affiliate marketing and Google Adsense. Went from nothing to over $400 per day investing just 20 bucks per day. Did that for around 4, 5 months till I got suspended. Big learning curve but a huge understanding of just how large this industry is. Very, very powerful once you understand the volume here and how to get it.
I sold my domain for 250 $.It was the first time I crossed 100 $ mark.All my previous earnings,mostly from ads, were below 100 $
I made mine on Wealthy Affiliate which to me, is one of the best ways to set up your own profitable online business and earn monthly income for years to come.
You did not even answer your own question correctly. There are ONLY two possibilities, you either sold something, or someone gave you the $100. So, did you sell something on clickbank or did someone on clickbank give you the $100??? As for me, I sold something, though cannot remember what.
I made mine 7 years ago with Google adsense. Wasn't easy though because of the work that was involved just to be able to rank my websites but it was worth the effort.
