Fix Conversion Tracking Before Smart Bidding in Dental Ads

Google's automated bidding strategies, like Maximize Conversions or Target CPA, can be very effective. They adjust bids for each search in real time, using signals no human could process. Many clinics switch them on hoping for more patients at a lower cost.

But there's a catch that's easy to miss. Automated bidding learns from the conversions you track. It tries to get more of whatever you tell it counts as success. If your tracking is wrong, the algorithm will work hard, and very efficiently, toward the wrong goal.

Before you trust Google with conversion-based bidding, make sure your tracking is right.

What can go wrong

These problems are common in dental ad accounts:

Counting the wrong actions

Some accounts count page views, clicks on the "Contact" menu item or time on site as conversions. The algorithm then finds people who view pages, not people who book.

Double counting

The same form submission is counted twice, for example once by a Google Ads tag and once by an imported Google Analytics event. Results look twice as good as they are, and the algorithm learns from inflated data.

Missing conversions

Phone calls from ads aren't tracked, or the booking widget on a third-party system isn't connected. The algorithm thinks campaigns that bring calls are failing and moves budget away from them.

Thank-you page problems

Conversions fire when someone loads the thank-you page, but the page can be reached directly, bookmarked or refreshed, creating fake conversions.

Treating every conversion as equal

A newsletter signup and an implant consultation request are counted the same way. The algorithm chases the cheaper, easier one.

Spam and junk submissions

Bot submissions or junk forms are counted as conversions. The algorithm may start finding more of the same.

How to check your tracking

1. List what you count

In Google Ads, open the conversions section and list every conversion action. For each, ask: does this represent a real potential patient? Is it set as primary (used for bidding) or secondary (just for reporting)?

2. Test each action yourself

Submit a form. Tap the phone number from an ad on mobile. Start a chat. Book online. Then check whether each action is recorded, once, in the right place. Google's Tag Assistant can help you see which tags fire.

3. Compare with reality

Compare conversions in Google Ads with what your front desk actually received over the same period. If Google says 60 form submissions and you received 30, something is wrong. If you received 50 calls from ads and Google shows none, calls aren't tracked.

4. Check for duplicates

Make sure each action is tracked by only one source for bidding purposes.

How to set it up properly

Choose meaningful primary conversions

For most clinics, primary conversions should be actions that clearly signal intent to become a patient:

• Appointment request form submitted.
• Online booking completed.
• Phone call from ad lasting longer than a set duration (for example 60 seconds).
• Chat or messaging conversation that results in a booking request, if trackable.

Secondary actions, like viewing the price page or clicking a WhatsApp button, can be tracked for insight but not used for bidding.

Use values if you can

If some conversions are worth more than others, like an implant consultation versus a checkup, assign different values. This helps the algorithm focus on what matters more.

Go further: import offline conversions

The best signal isn't a form submission. It's a patient who actually booked, attended and accepted treatment. Google Ads lets you import offline conversions from your CRM, so the algorithm learns which clicks became real patients. This takes more setup, but it's where bidding becomes really powerful.

Respect privacy rules

Use proper consent management for tracking, especially in the EU. Consent mode helps Google Ads work with users who don't accept cookies.

Give the algorithm enough data

Automated bidding needs volume. With very few conversions per month, it struggles to learn. If your account is small, a simpler bidding strategy may work better until you have more data. And after switching strategies, allow a learning period before judging results.

Check again regularly

Website changes, new forms, a new booking system or a plugin update can break tracking without anyone noticing. Test your main conversions at least monthly, and always after website changes.

How we approach it

When we start with a clinic, checking and fixing conversion tracking is one of the first things we do, before we scale budgets or rely on automated bidding. Our dashboards then follow results all the way to booked and attended appointments. See more on our Google Ads for dentists page.
