Every once in a while I like to write a DIY guide for any given niche and use it to build a list...
What I love to do is give "give away" rights to everyone who downloads it to build "their" lists.
These types of reports can really get on the "viral train" if you know what I mean...I was getting traffic from hundreds sites I have never even heard of or dealt with...one was actually a respected "ware" (I hove absolutely no clue how that happened).
So anyway, I just so happened to log on to an affiliate program that I haven't looked at in forever (I had stuffed my AFF Link in the guide) and sure enough, there was a notice that I had piled up commissions and needed to submit my tax info...UGH.
Anywho...needless to say...the check is on the way.
Two takeaways for me:
1) If you are a half-way decent writer, seriously think about investing some time in writing a solid DIY guide that people can use as a giveaway to build their lists (if they're too lazy to write their own - sometimes I am)
2) Never underestimate the power of compounding virality
