Why Are Impressions Important?
Impressions in terms of search marketing analysis is the metric that tell you someone is in your neighborhood. You're close. They're close. But you don't quite have what it takes to get them to knock and come in.
That's why it's important to track and manage your impression metrics. That data is going to point you to the flood of people you are looking for and if you're a good data blood houd analyst, it will lead you to the flood that breaks down your door.
A bit dramatic, but true.
