Microsoft Ads conversion tracking for fertility and IVF clinics
Fertility is among the most sensitive categories anyone advertises in, and it deserves more care than a generic agency will apply. What Microsoft Ads adds on top of that is a mechanical requirement: msclkid has to reach the record that holds the money, because Microsoft can only credit a conversion it can tie back to a click it recognizes. This page covers both halves — what a conversion is in fertility and IVF clinics, and what Microsoft specifically needs to accept it.

Microsoft Ads for fertility clinics: small volume, same rules
On Microsoft Ads, a fertility clinic imports the attended consultation and the started cycle as offline conversions keyed on the msclkid stored as an opaque reference in the clinic system, with the cycle valued at its price. UET fires only on neutral pages, and nothing clinical goes into the upload.
Bing searchers skew older and more desktop, which for fertility means more people in their late thirties and forties researching IVF, donor eggs or a second opinion. The intent is good; the volume is small. A clinic that gets a handful of started cycles a quarter from Microsoft won't give bidding enough to learn from, so make the attended consultation the goal Microsoft optimizes toward and keep the cycle as a reporting conversion.
UET sits on every page by default, which means it records URLs from treatment and condition pages. Microsoft has its own restrictions on personalized advertising around health, so don't build remarketing lists from those pages, and check whether UET is picking up full URLs with query strings from intake forms.
The usual failure comes from the Google import. Microsoft accounts copied from Google Ads arrive with conversion goals pointing at whatever thank-you page existed when they were copied, and if the Google side was later cleaned of condition-revealing paths, Microsoft's URL-based goals may still fire on the old ones. Rebuild the goals by hand, and confirm msclkid is stored by the same server-side code that stores gclid.
Microsoft · Fertility and IVF · what breaks
Why Microsoft under-reports for fertility and IVF clinics
- 01
Inquiry volume optimized as the conversion
Most inquiries are early-stage research at an emotionally difficult moment.
- 02
Treatment type and diagnosis leaking into ad platforms
Page paths naming a condition or a treatment send health information onward.
- 03
Cycle value treated as a single number
IVF, IUI and egg freezing differ enormously in price.
- 04
Msclkid never reaches the record
Microsoft's click identifier, appended when auto-tagging is enabled. It depends on the UET tag being present on the site — without UET, msclkid arrives in the URL and there's nothing consuming it, which is a common half-configured state on accounts imported from Google.
Microsoft · Fertility and IVF · the fix
What working looks like — Microsoft · Fertility and IVF
Started cycles as the conversion
From the clinic system, by treatment type, at the cycle price.
Nothing clinical in any payload
A value and a treatment category agreed as non-clinical. Nothing about diagnosis.
Consultations as the working target
Where cycle volume is too low for bidding to learn.

How Microsoft and fertility and IVF clinics actually connect
- 1
The conversion in fertility and IVF clinics
The money event is a started treatment cycle. Everything above it is measured for learning volume only, and each step is defined so that measuring it never requires recording why the patient came.
- 2
Microsoft Ads needs a click to match
msclkid inside the import window, a conversion goal name matching one in the account, a timestamp and a value.
- 3
The identifier: msclkid
Microsoft's click identifier, appended when auto-tagging is enabled. It depends on the UET tag being present on the site — without UET, msclkid arrives in the URL and there's nothing consuming it, which is a common half-configured state on accounts imported from Google.
- 4
Where it gets sent from
The clinic system — cycles started by start date, by treatment type, for the same window, with clinical fields excluded from the export.
- 5
Deduplication and window
The same counting question applies: one conversion per click for lead-type goals, every conversion for ecommerce. Accounts imported from Google frequently carry over the goal structure and not the counting review, so it's worth reading every goal rather than assuming the import got it right. Check Microsoft's current offline import window and attribution settings directly. They resemble Google's closely enough to be assumed and differ enough to matter.

The conversion map for fertility and IVF clinics
Five steps, defined deliberately narrowly in a category where the obvious data is the data you must not send.
| Event | What it means here |
|---|---|
| Inquiry | Volume signal. Nothing about circumstances. |
| Consultation booked | A leading indicator. |
| Consultation attended | The realistic optimization target. |
| Treatment plan agreed | A commitment, before money moves. |
| Cycle started | The money event, at the cycle price. |

Diagnostic order — Microsoft · Fertility and IVF

Count records carrying msclkid
- 02
Diagnosis or treatment in the URL
The most common exposure, and one that carries genuine weight in this category.
- 03
Generic form tracking capturing all fields
Which sweeps deeply personal free text into analytics events.

Two decision-makers, several devices
A couple researching separately fragments attribution.

Read the upload's match rate and Microsoft's conversion goal diagnostics
Almost every Microsoft account we open was imported from Google Ads, and the import copies campaign structure without copying the tracking. The result is a live account spending money with UET missing, msclkid unconsumed, or conversion goals pointing at pages that don't exist on the site any more.

- A live audit of every parameter, event and field currently leaving the site.
- Started cycles reconciled per patient against what each platform reports.
- A written statement of what is sent and what is never sent, suitable for compliance review.
- Confirmation that no diagnosis or treatment detail appears in any URL or payload.
- The upload's match rate and Microsoft's conversion goal diagnostics read directly, not inferred from an upload succeeding.

Microsoft · Fertility and IVF · when not to buy
When you don't need this — Microsoft · Fertility and IVF
- If Microsoft already reports conversions that reconcile against the clinic system within a few percent, this is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred records and count how many carry msclkid.
- If your Microsoft account is a straight import you've never separately configured, fix the account structure and UET installation first — offline import on top of an unconfigured account produces data nobody will trust.

FAQ
Microsoft · Fertility and IVF questions, answered
Often, as a small search line, because older patients researching IVF do use Bing. Judge it on attended consultations and cycles over a quarter, since monthly numbers will be too small to read.
Treat it as off-limits until you've checked Microsoft's current health-related advertising policy, because it targets people on a health condition. Plain search campaigns don't need it.
More careful than almost any other category. A fertility search reveals something private about a person's body and their life, and the fact of the inquiry is itself the sensitive fact. Send a click identifier, a timestamp, a value and at most a broad treatment category you have agreed is not clinical. Nothing else.
Cycles if the volume supports it; attended consultations if not. Inquiry volume in fertility is dominated by early-stage research at a difficult moment, and it predicts treatment poorly.
It fragments it — two people, several sessions, one decision, and click attribution credits whichever session converted. Persisting the identifier server-side from first visit helps; complete coverage is not achievable and the report should say so.
