William Goldman, the screenwriter, once said, regarding how to make a successful movie, that "Nobody knows nothing." What he meant was that there are simply too many unknowable factors that can influence the box office to be able to create a formula for success. So you try a bunch of things, and you hope they work.
The same can be said of Marketing - which is why we built LeadGen.com as a "one-stop shop."
The Rest of the Story...
When we recommend a solution to a client from among the dozens we have available, it's always based on our unbiased and educated analysis of their situation. But we always add the caveat that there's a risk that it might not work - because risk is intrinsic to Marketing.
If it works, great; we can scale it up. And if it doesn't work, we have dozens of other solutions we can try.
Because Nobody Knows Nothing.
