Referrals work because somebody hands over your judgement before you ever meet. They are also finite, and you cannot schedule them.
We spent twenty years being genuinely good at something and invisible for it, so we pointed twenty years of measurement discipline at our own marketing and wrote down every one of the sixty steps it took. There are two ways to use it, and they suit different people.
All sixty steps, in order, with the arithmetic and the parts that failed. You have the time and you would rather understand it than hand it over.
You have not got the time and you would rather buy the outcome. We write the book in your voice, build the funnel, buy the media, and hand you the buyers.
Not sure? Read the book first — it is the same method either way, and it is five US dollars.
