It’s a valid method to build your online fan base by spending a lot of money on advertisement. It’s proven, and it works.
The problem is, that method (especially online) is losing its effectiveness in an world that is now filled with noise and distraction — interrupting people with more noise when they are getting so good at filtering out noise simply isn’t smart.
This is when you should remember that advertising is only a (small) part of marketing. Now is probably as good a time as ever to ask yourself: if we take away advertising from our marketing, what are we left with?
…and is that enough?
