One of the biggest challenges to creating good/effective interactive marketing is that so many of us have no experience with which to judge our ideas against. We know, within reason, what makes a good TV spot or print ad. But what makes a good interactive idea?
The biggest thing to remember is not to judge interactive the same way you judge anything else. In TV and Print, a single simple idea clearly communicated is all you want. And to an extent, online should be the same. But there must be a consideration for the interactive nature of the internet. What is the user going to get out of the idea? How will they engage with it?
A good friend of mine sums up the requirements for a good interactive idea with three questions:
1) Why would the user interact with your idea?
2) Would they send it to their friends?
3) Will they return to experience it again?
Answer honestly and you'll help ensure your interactive ideas are as strong as possible. Answer with a bunch of bullshit and you'll have a really expensive glory piece that does nothing for your client and hurts your and your agency's rep.
