Why your Google Ads conversions don't match your sales
The five most common causes, and how to fix them.

Google Ads reports a healthy number of conversions. Your team closed far fewer deals. Both numbers can be "right" — they're just measuring different things. Here are the five causes we see most often.
1. You're counting actions, not sales
If a form fill, a WhatsApp tap or a call click is set as a primary conversion, Google counts every one of them. Some are spam, some are existing customers, many never buy.
Fix: keep these as secondary conversions for reporting, and give Google a conversion that represents real value — ideally a closed sale imported from your CRM or sheet.
2. The same conversion is counted twice
Duplicate tags are common, especially on accounts that several agencies have touched. A Google Ads tag and an imported GA4 conversion can both fire for the same action, or a thank-you page reload counts again.
Fix: audit Google Tag Manager, remove legacy tags, and make sure each action has one source. Set lead conversions to count "one" per click, not "every".
3. Conversions are reported on the click date
Google Ads attributes a conversion to the day of the ad click, not the day of the sale. A sale today from a click three weeks ago shows up in last month's numbers. Your sales report won't line up day by day.
Fix: compare longer periods, and use the "by conversion time" columns when reconciling.
If two numbers disagree, don't pick the one you like. Find out what each is counting.
4. Some conversions are modelled
When people decline cookies or switch devices, Google may estimate conversions it can't observe directly. That's useful for bidding, but it means reported conversions aren't a list of real people.
Fix: understand which columns include modelled data, and judge performance on sales you can verify.
5. Offline sales never reach Google
If deals close on the phone, on WhatsApp or in a showroom, Google never sees them — so it can't learn which clicks were valuable.
Fix: capture the click ID on arrival, record it against each lead, and upload closed sales as offline conversions.
Start with an audit
Before changing bids or budgets, list every conversion action in the account, what triggers it and whether it's primary. It usually takes an hour, and it explains most of the gap.
