You know the scene from Field of Dreams with the famous (misquoted) line, "If you build it they will come"? That doesn't actually work. You need an audience. Here's how to actually sell the damn thing. 1/n https://twitter.com/naval/status/1248464379655229440
If you already have an audience (say, a twitter profile with 795k followers), then you have an inherent advantage. Not sure what to launch? Survey them. Not sure if they'll buy? Just set up a pre-order page and see if anyone buys. Have market fit? Hit them with a sales funnel.
No audience? No worries. Guess who has HUGE audiences filled with people who probably want to buy whatever it is you built? Google, Facebook, to name a few. In fact, it's their whole business model. Pay them money and they will (begrudgingly) give you access to their audience
But I don't have any money to advertise, you say? Well, you probably don't have a business model either, but there's still hope! Think laterally - who else has access to your target audience? Pages in organic goog results, FBGroups, IG influencers, niche email lists etc
They all will want money too. But you can probably 1) pay a lot less and 2) structure it on a performance basis. For every sale/signup etc, you will pay them a commission. Structure this right and you make money ahead of your advertising spend. Congrats, you have an aff program!
I am leaving a ton out in the context of direct marketing, building out landing pages, funnels, tweaking ads, etc. I will leave it as an exercise to the reader. I will say that the concept (and book) of Ready Fire Aim will serve you well.
Finally, please don't start yet another course on how to make money online. If you're reading this thread you don't know how to anyway. But for some reason people always gravitate towards teach people about making money online even if they don't have the experience
