Why your Google Ads conversions don’t match your CRM

LEV BROVTSEV · JULY 31, 2026

Every owner I talk to has some version of this conversation. The report says 140 conversions. The intake manager remembers eleven consultations. Somebody is wrong, and nobody can prove who.

Neither side is lying. The two systems are counting different events, over different windows, with different rules about what a person is. Below is what actually causes the divergence, how much of it is normal, and what to do about the part that isn’t.

What each system is actually counting

Three reports, three definitions of the same word — and only one of them describes a patient.

Read that table again with your last monthly report in hand. Most of the argument disappears once it’s clear the three columns were never candidates for the same number.

Five reasons the numbers diverge

In order of how much damage they usually do, not how often they get blamed.

1. The conversion action is too generous. A call conversion typically fires at 60 seconds. A wrong number, a supplier and a patient asking about parking all clear that bar. If a meaningful share of your enquiries arrive by phone — and in high-ticket healthcare they do — this alone can explain most of the discrepancy.

2. Modeled conversions aren’t records. When Google can’t observe a conversion directly — consent declined, cross-device path, browser restrictions — it estimates one. Those estimates are often directionally reasonable at account level. They will never appear in your CRM, because there is no person attached to them.

3. The dates don’t line up. Google credits a conversion to the day of the click, retroactively, inside a window that can run 30 or 90 days. Your CRM credits the day the record was created. Compare two calendar months side by side and you are comparing partially different cohorts.

4. Deduplication runs in opposite directions. Your CRM merges a returning patient into the existing record. Google, by default on lead actions, counts every submission. One person filling in three forms is one CRM record and three conversions.

5. The click ID doesn’t survive intake. This is the quiet one. If the GCLID isn’t captured on the landing page and written to the lead record — through the form, the chat widget and the call tracking — then even a perfectly clean CRM cannot tell you which campaign produced which patient. Nothing downstream recovers it.

How big a gap is normal

Ten to twenty percent is ordinary and not worth a meeting. Beyond that you are no longer looking at a reconciliation problem.

When the platform reports two or three times what the CRM can find, the definition is wrong, not the arithmetic. Something is being counted as a conversion that your business does not consider a lead — and because bidding optimizes toward whatever it can see, budget has already been moving toward whatever produces the most of that thing.

This is the mechanism behind a pattern most owners recognize: cost per lead falls every quarter while the metrics that describe the business quietly get worse.

Reconcile the two reports in one afternoon

You can do this yourself, without your agency, in about three hours.

• Open your conversion actions in Google Ads and write down, for each one, what event fires it and what counting setting it uses (every vs one). Most owners have never seen this screen.
• Check the call conversion duration threshold. If it is 60 seconds, raise it to 90 or 120 and watch what happens to reported volume.
• Split reported conversions into observed and modeled. If modeled is a large share, stop expecting the CRM to match it.
• Export 30 days of CRM records and check how many carry a GCLID. If the answer is none, that is the finding — everything else is guesswork until it’s fixed.
• Pick one week and match it line by line, by person, not by total. Ask which conversions have no CRM record, and which records have no conversion.
• Name the stage in your CRM where money is genuinely confirmed. Consultation attended, admitted, closed-won. Write it down — you’ll need it in the next step.

How to close the gap permanently

Stop trying to make two reports agree and give the platform the CRM’s definition instead.

That is what offline conversion import does. The click ID is captured at the landing page and stored on the lead in your CRM. When the record reaches the stage you named above, that outcome is sent back into Google Ads and Microsoft Ads against the original click, with the revenue value attached. Bidding then optimizes toward the thing you sell rather than the thing it could see.

Nothing about the patient leaves your systems — a click ID, a timestamp, a conversion name and a value. Google documents the mechanism for offline conversion imports and separately explains how modeled conversions are produced; Microsoft has an equivalent import keyed to MSCLKID.

Two warnings, because this is where owners get surprised. Implementation takes two to four weeks and most of that is CRM work, not ad work. And once it’s live your reported conversion volume will fall — sometimes sharply — while cost per confirmed patient improves. That is the system working. If nobody warns you in advance, it reads as a disaster.

VERIFIED EXAMPLE · When I inherited a wasteful account at a luxury US healthcare clinic, it was optimizing toward platform conversions. Rebuilt around admitted patients imported from the CRM, cost per admitted patient fell ~78% while spend scaled ~2× and approved patients rose ~9×.
