No No - that's called marketing by blunderbuss and is like finding a needle is a haystack.
I'm afraid you're confusing 1955's interruptive (blunderbuss marketing) with 2005's inbound marketing.
The goal is not to force your way into an auditorium and strongarm everyone you bump into until you find a prospect who will listen, or sift through a haystack to find a square peg.
Inbound marketing relies on the business putting forth the right types of messages into the right channels so as to facilitate the prospective buyers journey. Those who aren't on the path to making a purchase will likely self-filter themselves out of the loop, while those who are, will find the message striking a chord with them as they nod in agreement throughout.
If I'm offering a coaching service for small business owners, I'd be searching for 'small business advice', 'small business help' and seeing what types of sites they prospects are seeing when they make a similar search. I'd also have a look at 'small business funding' and 'small business grants' plus 'small business loans' to see where the cash-strapped are getting their information from.
Obviously there's more than one scenario (or persona) to the big picture of this, but a cocktail napkin example, as above, would lead me to a number of page one results. In my searches, I'd surely have looked at 'small business forums' and landed on UKBF.
A well placed post, guest post, advertorial, or other valuable content which readers would find relevant and remarkable would go a long way introducing the brand, ingratiating themselves and demonstrate a pay it forward mindset while showing they are abreast of current issues and matters of concern to them.
Personally, I'd much prefer finding a vendor that way than having them call me out of the blue, without so much as knowing my name, and trying to twist my arm until I say no 8 times, as they interrupt what I'm in the middle of, to sell me something I may not want or need.
There's a reason organic SEO outperforms PPC ROI (content/display network especially) consistently. One relies on being seen with a solution at a time when people have a problem and the latter relies on carpet bombing an audience with an often times irrelevant message.
Inbound marketing relies on segmentation, targeting prospects based on common demographics, and using personas to understand the archetypes, at least if done properly (and much, much more).
It's not a horde of cave men wielding the leg of a T-Rex in order to squash a flea.
Sorry, but interruptive marketing, like those draconian 1 year contracts that clients are locked into, just so the company can safeguard their annual income forecasts irregardless of their crappy service or products, is a dinosaur. Maybe that horde of cave men should wield that instead...
