Your Ads Report Conversions but No Leads Arrive: How to Find the Tracking Break

The question underneath: is the problem the ads, or the counting?

The instinct is to pause the ads, rewrite them, or change agencies. First find out what the Conversions column is counting. If Google is counting page loads as conversions, better ads will not produce more leads, and Google's automated bidding will keep buying more of whatever triggers that page load.

The fastest way to see the break is a simple count. Pick one recent week. Write down the number for that week in each system:

The numbers above are invented to show the method, not taken from any account. In this example, the gap between 41 and 27 says Google Ads is counting something beyond real form submissions. The gap between 27 and 12 says submitted forms are not all reaching sales. Those are two different problems with two different fixes.

1. Check which conversion actions Google Ads is counting

In Google Ads, open Goals, then Conversions, then Summary. You will see every conversion action in the account. For each one, check five things.

• Primary or secondary. According to Google's help page on primary and secondary actions, primary actions are "reported in the 'Conversions' column" and used for bidding, while secondary actions are "for observation only" and appear in "All conversions". If two primary actions record the same form fill (for example, a Google Ads tag and an imported Google Analytics event), each lead is counted twice in the Conversions column. Keep one as primary and set the other to secondary.
• What triggers it. A conversion that fires on a page load must fire only on a page a visitor reaches after submitting a form. A rule that matches the home page, or a thank-you URL anyone can open without submitting, counts visits as leads.
• Count setting. Google offers "Every" or "One" conversion per ad click. For leads, Google recommends "One", because "usually only one, unique lead per ad click likely adds value for your business."
• Status. Statuses such as "Unverified," "Tag inactive" or "Needs attention" mean the tag is not being seen as expected. Google's troubleshooting page opens Tag Assistant from the status so you can test it.
• Source. Note whether each action comes from the website tag, a Google Analytics import, phone calls, or an import from another system. You will need this in steps 3, 4 and 5.

Two more things explain gaps that are not errors. Google Ads reports conversions on the date of the ad click: "if your ad was clicked on last week and that traffic converted this week, both the click and the conversion are reported back to last week," as Google explains. And Google's page on data discrepancies lists modeled cross-device conversions, conversion windows and attribution models as other reasons Google Ads and other tools disagree. Add the "Conversions (by conv. time)" column when you compare against your CRM.

2. Test the tag that fires the conversion

Submit a real test lead yourself while watching the tag. Open Tag Assistant, connect it to your landing page, fill in the form, and check which tags fired and when.

Breaks to look for, all of them easy to miss:

• The trigger listens for the wrong form. The tracking was set up for one form tool and the site now uses another, so real submissions never fire the tag, while some other rule keeps firing.
• The tag fires on the attempt, not the success. In Google Tag Manager, the form submission trigger has a "Check Validation" option. Google's Tag Manager help says that without it, "the trigger will fire whenever a user attempts to submit the form," including attempts that fail.
• The thank-you page is reachable without a form. It is linked in the menu, indexed in search, or bookmarked by staff.
• There is no form at all. The ad sends people to a page with a phone number and an email link, so nothing is measured against the clicks.

If the tag fires once, on a successful submission, and nowhere else, move on.

3. Compare Google Analytics key events with Google Ads

In Google Analytics 4, what used to be called conversions are now called key events. Google defines a key event as "an event that measures an action that's particularly important to the success of your business," and a conversion as an action used to measure and optimize ad campaigns. You can mark an event as a key event in Admin, under Data display, then Events, and import it into Google Ads.

Check three things here:

• Is the right event marked as the key event? Look for the event that fires on a completed form, not a page view or a button click.
• How is it counted? GA4 can count a key event once per event or once per session. Google's page on counting methods explains both and which is the default for each kind of key event. A mismatch here explains some gaps between GA4 and Google Ads.
• Does the visit cross domains? If the booking tool, store or form lives on a different domain, GA4 treats one visitor as two without cross-domain measurement. Google's cross-domain page says a user crossing root domains "will be identified separately (two users and two sessions instead of one user and one session)." The same thing happens when the main site and a store report to two different Analytics properties.

If Google Analytics sees the right form completions and Google Ads does not, the problem is in the import or the Google Ads tag. If neither sees them, it is in the tag or the form.

4. Check what counts as a call conversion

Phone call conversions need their own check, because Google lists five types of phone call conversions, and they do not all measure a call:

• Calls from ads and calls to a Google forwarding number on your website count when the call lasts at least a minimum length that you set. Check what that minimum is. A very short minimum counts hang-ups and wrong numbers.
• Clicks on a number on your mobile website count the tap, whether or not a call follows. Clicks on call ads and assets that do not use a Google forwarding number count as a conversion when Google estimates that a meaningful phone call took place. Either way, a counted click is not a confirmed lead: match these conversions against your phone records and your CRM.
• Imported calls come from your own call tracking system, with whatever rules that system uses.

Then listen to, or log, a week of calls from ads. Existing customers, vendors and job seekers all call the number in an ad. They count as conversions and are not leads.

5. Follow the form into the CRM

Now take the forms that were really submitted and find each one on the other side.

• Does every submission arrive? Check the notification email address, the spam folder, and the connection between the form and your CRM. A form can work on the website and still send nothing anywhere.
• Is it routed to a person? A lead in the CRM that no one is assigned to call is a lead lost. See lead routing and assignment rules for medical device sales.
• Is spam filtered? Bot submissions inflate every count above this step.
• Does the CRM keep the ad click? Your form should capture the Google click ID (GCLID) in a hidden field and store it with the lead. That is what lets you send results back to Google.

Once the CRM records which leads are qualified, send that status back to Google Ads with offline conversion import or enhanced conversions for leads, which Google describes as "an upgraded version of offline conversion import that uses user-provided data, such as email addresses," to improve accuracy and bidding. Then Google can bid toward qualified leads instead of every form fill. For what "qualified" should mean, see the marketing qualified lead definition for medical device companies.

Why fixing the count changes what Google buys

Google's automated bidding learns from your primary conversions. If the conversion tag does not fire when a real lead comes in, Google is never told, and if Google does not know, it cannot go find more people like that lead. If the tag fires on the wrong thing, Google finds more of the wrong thing.

So after a fix, expect your reported conversions to drop. That is the number becoming honest, not the ads getting worse. Give the bidding time to adjust: Google advises you to "allow enough time (at least one conversion cycle) to pass before evaluating performance," in its help page on how bidding learns. Do not rewrite the ads in the same weeks, or you will not know which change moved the number.

What does not work

• Judging the campaign by Google's Conversions column alone. It shows what Google is counting, which may not be leads.
• Counting a page view as the conversion. The conversion should be the business action you want: a booked appointment, a sample request, a demo request.
• Adding budget to find out. More spend on broken tracking buys more of the wrong conversion.
