One school of thought is to measure everything. If you can't measure it, don't do it. This is the direct marketer method and there's no doubt it can work.

There's another thought, though: Most businesses (including your competitors) are afraid of investments in unmeasurable media. Therefore, if you have the resources and the guts, it's a home run waiting to be hit.

Ralph Lauren is a billion dollar brand. Totally unmeasurable. So are Revlon, LVMH, Donald Trump, Andersen Windows, Lady Gaga and hundreds of other mass market brands.

There are two things you should never do:

1.   Try to measure unmeasurable media and use that to make decisions. You'll get it wrong. Sure, some sophisticated marketers get good hints from their measurements, but it's still an art, not a science.

2.   Compromise on your investment. Small investments in unmeasurable media almost always fail. Go big or stay home.

3.   Out of all unmeasurable media, remember your audience and know that they need to know you before they trust you.  Radio and TV can best articulate your story.

4.   The power of the story is unmeasurable. It’s your story, but consumers always love listening to a good story no matter who it’s from.

And if you're selling unmeasurable media? Don't try to sell to people who are obsessed with measuring. You'll waste your time and annoy the prospect at the same time.
