Measuring PR without advertising equivalency

Advertising value equivalency multiplies the space a story occupied by the cost of buying that space as advertising. It has been formally rejected by the industry's own measurement standards, and it persists in reports because it produces a large number.

Why it fails

It treats a critical article and a favourable one as equally valuable. It ignores whether the key message appeared. It can be inflated by placing coverage in expensive titles regardless of relevance. And it implies a substitutability between editorial and advertising that does not exist in either direction.

The three levels to measure

Outputs. What was produced and placed. Number of articles, publications, reach, prominence, and whether the key messages appeared.

Outtakes. What the audience took from it. Awareness, message recall, attitude, measured by survey.

Outcomes. What changed in the business. Enquiries, applications, brand search volume, sales.

Most reporting stops at outputs, which is the least meaningful of the three.

A practical measurement set

Message penetration is the most useful and least used. Coverage that mentions you without carrying the point you were making has achieved less than it appears.

The share of voice measure

Counting your coverage against three named competitors, monthly, produces a comparative figure that survives the argument about absolute value.

It also reveals when a competitor's programme is outperforming yours, which is actionable in a way that an equivalency figure never is.

Brand search volume

Free, monthly, and it responds visibly to significant coverage. A spike following an article is direct evidence that people acted on it.

It is the closest thing to a reliable, cheap, continuous outcome measure available in public relations.

Setting expectations before the programme

Agree what will be measured before it starts, including what success looks like. Public relations disputes are almost always about evaluation criteria that were never set.

A workable agreement: a target for coverage in named publication tiers, a message penetration threshold, a share of voice target, and one business outcome that will be tracked.

The honest limitation

Public relations effect is real, delayed and difficult to isolate. A measurement framework that admits this is more credible than one producing a precise return figure.

Report what was achieved, what is believed, and what is being tested. That structure survives scrutiny; a single inflated number does not.
