What is trial-to-member conversion rate?
Trial-to-member conversion rate is the share of people who started a trial and then paid for a membership: paying members divided by trials started. It measures the offer and the front desk, not the ad.

The trial-to-member conversion rate for gyms
A trial is the moment a prospect stops being a name and becomes a person in your building for a few days: a free class, an intro week, a paid starter offer. Some of them join and some of them drift. Trial-to-member conversion rate is the share who paid for a membership afterwards, divided by the number who started a trial, for the same period and location.
It is a different measurement from lead conversion, and the difference matters. By the time someone starts a trial, the ad has done its job. What happens next is the coaching, the welcome, the follow-up on day three, the offer at the end of the week and the confidence of whoever asks for the sale. A poor rate here is rarely an ad problem, and fixing the ads will not move it.
Read it by source anyway. A free-class ad and a paid-intro ad send different people into the same trial, and the rate for each tells you which offer is filling the room with future members and which is filling it with a free workout. It sits beside show rate, which measures the step before, and lead-to-member conversion rate, which measures the whole chain. A cheap lead is not a cheap member, and a busy trial week is not a full gym.
Where it misleads: counting sign-ups as trials. Someone who claimed a free week and never came in is a lead who did not show, not a trial that failed to convert. Count trials that started, count members when the payment clears, and give each trial a fixed window to convert.
How Adsu uses the trial-to-member conversion rate
Adsu tracks booked, showed, trial and paid as separate stages and counts only the ones it verified, so the trial that converted and the trial that did not are both on the record with the campaign that produced them. Adsu counts verified stages only: if a stage cannot be verified, it is not counted. Every report is one line per campaign per location.
Adsu credits the last eligible touch inside the 30 days before the payment. Booked, showed and paid go back to Google as offline conversions and to Meta through the Conversions API. Because the paid stage goes back as its own signal, the platforms learn the difference between someone who tries a class and someone who joins.
Questions, answered.
Yours, per source and per location, read over enough trials to mean something. The rate depends on the trial you offer, the price at the end of it and how your team follows up, and a studio selling a paid intro will convert differently from a gym giving away a free week. Measure it by source, find the offer that produces members who stay, and put the budget there.
Neither. A trial is its own stage between showing up and paying. Count the person as a lead when they enquire, as a show when they walk in, as a trial when the trial starts, and as a member only when the membership payment clears. Folding the trial into either end hides the step where most gyms lose people.
Treat the trial as a sales process rather than a free sample. Book the first session at a fixed time with a named coach, check in during the trial, make the membership offer before it ends rather than after, and follow up with everyone who does not decide on the spot. Then send the paid stage back to the ad platforms so they find more people who convert.
