Let's First Be Clear What Your Goal Is
To answer how many ads to deliver, let's first be crystal on what your goal is, because we often hear confusion on this point.
The goal of a public affairs campaign is not to create recall as it is in other forms of advertising. So throw out metrics you might hear like the "rule of 7," which are about creating brand awareness, or perhaps increasing name I.D. for a candidate.
The goal is not necessarily even to persuade politicians of the merits of your point. Businesses with public affairs challenges often mistakenly hold this belief—the wishful thinking that if you simply convince politicians that you're right on the policy, they will enact it. We'd have much better laws in this world if things were that simple.
Policy may be part of the calculus when a politician goes to vote, but what we're concerned with in a public affairs campaign is politics, much more than policy. So the precise goal of a public affairs campaign is to tip the balance of the politics on your issue. In other words, the true underlying question in determining how many impressions to deliver is: "how many impressions will tip the balance on my issue?"
The answer to that question will depend on numerous inputs such as:
- How politically charged is your topic?
- Has your ask failed before?
- How far ahead or behind are you to begin with?
- Who is the opposition and how well-funded and connected are they?
- How well-executed is your campaign and the opposition's?
- How expensive is your ask to taxpayers?
- How scarce are government dollars in the current budget environment?
- How many competing priorities does the government body have?
- How powerful are your bill sponsors or the opposition's?
- How strong is your coalition and the opposition's?
. . . and countless other both concrete and subjective inputs that create the full political picture of your issue.
