I often get asked if I’ll work “on spec” to prove that our services work. I have done it in the past, in fact my first 3 clients were gained by striking a deal where I get recompensed after the initial work was done, usually by using an affiliate link.
Now, while I can guarantee new clients good quality targeted traffic and to some extent affordable leads, I have no control over what you do with those leads. That’s about your conversion of leads to sales process. So the answer nowadays is the same as many of these people give in this funny video… #SayNoToSpec
