Your blended RPV is hiding your worst channel

Your blended RPV is hiding your worst channel

A blended RPV is an average. And averages are where your worst channel hides.

Last week the pitch was simple. Calculate revenue per visitor before your CFO does it for you. Plenty of you ran the number. This week is the part that stings.

The blended number is a comfort blanket. One channel is almost always carrying it while another quietly drags it down, and the average smooths the whole thing into something that looks fine. It is not fine. It is hidden.

Segment RPV by acquisition channel and the budget conversation flips. Your highest-volume channel is very often your lowest-yield one. The traffic looks like a win on the slide. The revenue per visitor says it is mostly motion. Meanwhile some small channel, direct, email, a tight branded campaign, is doing the actual earning on a fraction of the spend.

Volume was never the point. Yield was.

Here is the move most teams make next, and it is the wrong one. They defend the big low-RPV channel with a story. "But it is top of funnel, it assists everything downstream." Sometimes true. Mostly reflex. The assist defense is the most abused sentence in marketing, because it can never be disproven in a meeting. So stop letting it be asserted. Make it be shown.

Three things to do this week

  1. Rank channels by RPV, not by volume. Same data, reordered. The ranking alone resets which channels your team treats as winners.
  2. Find your volume tax. The channel eating the most spend at the lowest RPV. That is your first candidate for a cut, not your sacred cow.
  3. Pressure-test every assist claim. Before you protect a low-RPV channel as "top of funnel," make it prove the downstream lift. A holdout test or a path analysis. A number, not a story.

The blended number tells you how you are doing. The segmented number tells you what to do about it.

So the harder question, the one your CFO will eventually ask in plainer words: which channel are you protecting with a story instead of a number?

Frequently asked questions

What is blended RPV? Blended RPV is total revenue divided by total visitors across every channel. It is a single average. It tells you how you are doing overall, but it hides which channels earn and which burn.

How do I segment RPV by channel? Take revenue and visitors for each acquisition channel separately (direct, email, paid search, social, organic) and divide. Compare the per-channel numbers, not the blend.

What is a volume tax? The channel eating the most spend at the lowest RPV. High traffic, low yield. It is usually the first place to cut, not the channel to protect.

Is a low-RPV channel always worth cutting? No. Some genuinely assist downstream. But the "it is top of funnel" defense has to be proven with a holdout test or a path analysis, not asserted in a meeting.
