Everyone converts on a twenty-nine dollar intro. The year is decided afterwards.

Nearly every channel in this category leads with a discounted intro — a week unlimited, a first class free, a trial month — so the first transaction is close to identical whatever produced it.

A ranking built on it is a ranking of who gave away the most, and it is stable, available immediately and useless.

The separation happens when the intro ends and the client either buys a membership or disappears, which is weeks later and invisible to any advertising platform.

Revenue per acquired client across six to twelve months is the figure that survives, and it routinely reorders a ranking built on cost per intro.

It also puts a number on the intro itself: whether a cheaper offer that converts worse is actually cheaper.

A member on autopay is predictable revenue with a known life. A pack buyer is a series of decisions. An intro-only client is a cost.

Channels differ sharply in which of those they produce, and the difference is far larger than any difference in their cost per lead.

Because the report sums by client across the window, conversion to membership shows up as revenue rather than as a rate somebody has to compute separately.

That makes it comparable across channels without any extra discipline in the studio, which matters when the person running the marketing also teaches.

The usual finding is that the most expensive channel per intro is the cheapest per member.

Aggregators and pass networks fill classes, and they do it with people whose relationship is with the aggregator rather than with the studio.

That revenue is real and often worth having in off-peak hours; it is not evidence that the studio's marketing works, and it converts to membership at a different rate.

Separating marketplace arrivals from the studio's own acquisition is the first split worth making, and it is available wherever the lead file distinguishes them.

Ranking them on revenue per acquired client against their commission is what turns an argument about aggregators into a calculation.

A member who stays fourteen months is worth several times one who cancels in month three, and cancellation is influenced by what the client was promised.

A channel that sold on price brings members who leave on price; one that produced somebody who came with a friend usually does not.

Because the report reads months of sales, attrition appears as revenue stopping rather than as a churn report somebody has to join by hand.

It also exposes the channel that looks strong for a quarter and produces nothing in the second, which a short window would have rated highly.

For a studio the practical use is the renewal conversation. Knowing which sources produce members who reach month six tells you where to spend before the January rush rather than after it, which is the only time that decision can usefully be made.
