One of the best tactics I have taken to grow Lead Cookie is to give away 100% of our secret sauce. I wrote up this blog post that gives away everything including our scripts, tactics and exactly what we do for our customers to generate leads.
This post has just exploded and still continues to be shared all over the place even 6 months after publication. It has become a massive lead source for us and creates a lot of trust with prospective buyers.
You can see the article below. We give 90% away in the article and then do a content upgrade that requires an opt-in if someone wants our scripts.
