Which PR metrics actually matter vs. vanity metrics?
Four metrics matter: share of voice in your category, message pull-through (the story carries your framing and quotes you as the source), placements in outlets your actual buyers read, and referral traffic that converts. Impressions, AVE figures (advertising value equivalency, the discredited ad-rate metric), and raw mention counts are vanity metrics. They measure the theoretical size of an audience. The real four measure what the coverage changed.
Vanity metrics survive because they inflate on demand. An agency can report a thin month as millions of impressions with no placement worth naming, because impressions count an outlet's entire readership whether or not anyone read the piece. AVE is worse; the page on why AVE is discredited makes the full case. The buyer cue is short: an agency that leads with an AVE number is using a method its own industry threw out. Marketers on r/marketing reach the same conclusion: "vanity metrics don't pay the bills."
Each of the four replaces a vanity counterpart in the same report slot, plus a fifth worth tracking:
| Metric that matters | The vanity version it replaces | What it proves |
|---|---|---|
| Share of voice in your category | Total impressions / "reach" | Buyers researching the space find you |
| Message pull-through | AVE dollar figure | The reporter carried your framing, not a competitor's |
| Placements in outlets buyers and investors read | Coverage anywhere at all | Credibility where decisions actually get made |
| Referral traffic that converts | Social likes on the coverage | Readers acted on the story |
| Branded search lift after coverage | Press-release pickup counts | People remembered you and looked you up |
Share of voice matters more than it did five years ago because buyers increasingly ask an LLM before they ask a colleague, and LLMs cite the coverage that exists. A recent G2 survey found about half of B2B software buyers now begin product research with an AI chatbot, and a third ended up buying from a vendor they had not heard of beforehand. Those tools surface the coverage that already exists, so share of voice now shapes which vendors a buyer discovers at all. Message pull-through separates a placement that sells your story from one that merely mentions you. Referral traffic and branded search are the bridge to revenue; the page on tying PR to business outcomes walks through attribution mechanics and their limits.
One more thing to demand: activity visibility. Outcome metrics lag by months, so you also need to see the pipeline, which pitches went out, to whom, and what came back. An agency doing the work can show you every send, reply, and pass; insist on that visibility whatever the volume. How these metrics assemble into a single readable document is the job of the monthly report page.
