Which channels produced completed procedures?

Every channel produces consultation bookings. Conversion to surgery varies by a factor of three between them, and cost-per-consultation reporting cannot distinguish a channel producing decided patients from one producing curious ones.

Ranking on completed procedure revenue rather than consultations booked is the correction, and in this category it commonly redirects half the paid budget.

Refractive surgery is elective, expensive and mildly frightening. Patients consult, defer, and return the following year when finances or nerve allow.

There is no attribution window, so a procedure completed a year after the consultation still credits the campaign that produced it — which is exactly the revenue currently sitting unattributed.

A substantial share of people who book a screening are found unsuitable for the procedure they inquired about. That is a clinical outcome and not a marketing failure, but the rate at which it happens is not the same across sources, and that difference is a marketing fact of the first importance. An advert leading on a headline price attracts people for whom price is the deciding factor, and price-led demand skews toward prescriptions and eye conditions that the cheapest procedure does not suit.

The center experiences this as a busy screening diary and a disappointing surgical list. The advertising account experiences it as a healthy conversion rate, because a booked screening is what the pixel was told to count, and nothing ever goes back to amend that record when the patient is told they are not a candidate. So the campaign producing the highest volume of screenings can simultaneously be producing the lowest volume of operations, and both facts sit in the same building unexamined.

Using the screening list as the lead file and the collected-procedure list as the sales file puts screenings and procedures side by side for every source, with no modeling and no assumptions. A center that looks at it may well keep the price-led campaign and move the qualification earlier — a question on the form, a different landing page, a pre-screening call — rather than switching it off. The volume was genuine; it was simply being filtered after the expensive part of the process instead of before it. Procedures per hundred screenings by source is blunt, unarguable and immediately actionable in a way that cost per booking never was.

Co-managing optometrists are the backbone of refractive surgery volume in most markets. They see the patient first, raise the possibility, refer to a center they trust and often provide the follow-up care afterwards. The relationship is maintained with visits, lunches and continuing-education evenings, and it is assessed on a general impression of who has been sending people lately. The center knows the names and has no figure for what any of them is worth. Nobody in the building would describe that as a rigorous way to manage the largest source of surgical volume, and nobody has had an alternative to offer either.

Meanwhile the entire marketing budget is scrutinized weekly to two decimal places. That asymmetry produces predictable decisions: another few thousand on search, because search is the thing that can be measured, and no change at all to the way the practice invests in a referral network that may be producing most of the surgical list. The imbalance is not a judgment about relative value — it is a judgment about relative visibility. The referral network is not ignored because anybody thinks it unimportant; it is ignored because there has never been a report with its name on it.

Listing each referring practice as a source in the inquiry file ends the asymmetry in an afternoon. Referrers are then ranked on collected surgical revenue beside paid channels, with counts alongside so a total carried by one unusual case is obvious. The ranking by revenue may look nothing like the ranking by volume everybody carried in their heads, and two or three relationships may deserve considerably more attention than they have been getting.

Refractive surgery has one of the most pronounced seasonal patterns in elective medicine, and the cause is administrative rather than clinical. Patients with tax-advantaged medical accounts have money that expires at the end of the year, and they spend it in November and December. A center comparing December's channel performance with October's is measuring a calendar deadline and attributing it to whichever campaign happened to be running. The same effect runs in reverse in January and February, when the accounts have reset and the demand that looked inexhaustible in December simply is not there any more.

That misreading is expensive in both directions. Campaigns launched in the autumn look brilliant and get scaled into a first quarter where the same spend produces a fraction of the result. Campaigns launched in February look weak and are cut before the season they were built for arrives. The pattern repeats annually, and the only defense against it is to compare a period against the same period a year earlier rather than against the month before. Centers that have been through two or three of these cycles usually recognize the description immediately, and usually cannot prove it, because their reporting horizon has never been longer than the campaign under discussion.

Comparing like with like is possible immediately rather than after a year of collecting data, because nothing needed to be installed when last November happened. The screening logs and the billing records were kept for their own reasons, and both can be uploaded now. A center that starts with two matched quarters from previous years has a seasonal baseline on its first afternoon, which is the difference between reading a campaign result and reading a diary. That baseline is also what makes an honest conversation with an agency possible, since both sides are then arguing about the same seasonal shape rather than about whether one exists.
