Share of Presence: The Number Your Marketing Dashboard Is Missing
Open any B2B marketing dashboard and you will find share of voice, share of search, share of wallet. Every meaningful channel eventually gets a share metric, because a share metric is what turns activity into position. Spend is an input. Share is where you stand.
Physical presence never got one.
Companies spend enormous sums standing in rooms — booths, sponsorships, speaking slots, delegations, the flights and freight and weeks of preparation that surround them. Then they report on it with attendance figures supplied by the organiser and a count of badges scanned. Neither answers the only question that matters strategically: of all the attention available in the rooms where our market gathers, how much was ours?
That is what Share of Presence measures.
What it actually is
Take every event in your category over the last twelve months. Each has an audience. Add those audiences together and you have the total attention available in your market's physical world — the denominator.
Now take the events your company actually showed up to, in any role: exhibiting, sponsoring, speaking, attending. Add up their audiences. That is your numerator.
Your Share of Presence is the ratio. One number, between zero and a hundred percent, that says how much of your market's gathered attention you were in front of.
It behaves the way a share metric should. Attending one enormous, well-attended show can beat attending six small ones — because reach is reach, and a share metric should say so. Doing more events without doing bigger or better-attended ones moves the number very little, which is exactly the correction most event programmes need.
Why it changes conversations
Three things happen when a company sees this number for the first time.
The absolute count stops mattering. "We did thirty-two events last year" is an activity report. "We covered nine percent of our category's audience, against a competitor average of fourteen" is a position — and it is the version a CFO can act on.
Gaps become visible. If a rival's share is materially higher than yours, that difference lives in specific rooms you weren't in. Those rooms are enumerable. Suddenly the planning conversation has candidates in it rather than opinions.
Trajectory means something. A share that has drifted down over three years while your spend stayed flat tells you the market moved and your calendar didn't. No single event report would ever have shown you that.
What it is not
It is not a measure of what happened at the event. It says nothing about the quality of your conversations, the leads you captured, or the deals that followed. Those are downstream, and they depend on your booth, your team and your follow-up — things we cannot see and would not claim to.
It is not a complete census of the physical world, either. It is a share of tracked audience reach: the events, editions and participation records in our graph, which is the largest such record that exists but is not everything. We compute it the same way for you and for everyone you compare against, which is what makes the comparison fair even where the coverage is partial. And we say so on every number rather than rounding our uncertainty into your favour.
The point of a share metric
Share of voice did not make advertising effective. It made advertising legible — comparable, trackable, arguable. Before it, every campaign report was a story about activity. After it, there was a position to defend or take.
Physical presence has been stuck in the story-about-activity era for as long as it has existed, for the simple reason that nobody had the record required to compute the denominator. That record now exists.
The first number is usually a surprise. Most companies guess high.
