Google Ads conversion tracking records the valuable actions people take after clicking your ads, such as purchases, form submissions and calls, so you can see which campaigns actually produce results. Setting it up means choosing the right actions, installing the Google tag or importing goals from GA4, and testing that every conversion is counted once. This checklist from Glorvix.com covers each step and the mistakes we see most often.
Key takeaways
- Track actions tied to revenue, and mark only the most important ones as primary conversions.
- Use either the Google tag directly or GA4 key event imports, and avoid counting the same action twice.
- Enhanced conversions send hashed first-party data to improve measurement accuracy.
- Test every conversion action with a real submission before you trust the numbers.
- Review tracking after any website change, because broken tags quietly distort bidding.
Why conversion tracking matters
Without tracking, you can see clicks and spend but not outcomes. That makes it impossible to tell a profitable keyword from an expensive one. Google describes conversion measurement as the way to see how effectively ad clicks lead to valuable customer activity.
Tracking also feeds automated bidding. Strategies such as Maximise Conversions or Target CPA rely on conversion data to decide how much to bid, so inaccurate data leads to poor decisions at scale. If you are still planning spend, our guide to Google Ads cost explains how budgets and bids interact.
Step 1: Decide what to track
Start with a short list of actions that represent real business value. Tracking everything sounds thorough, but too many primary goals confuse both reporting and bidding.
| Business type | Primary conversion | Useful secondary actions |
|---|---|---|
| Online store | Completed purchase with order value | Add to cart, begin checkout |
| Service business | Quote or contact form submitted | Clicks on phone number, brochure download |
| Local trades | Phone calls from ads or website | Direction requests, booking page views |
| B2B or SaaS | Demo request or trial sign-up | Pricing page visits, webinar registrations |
Mark revenue-linked actions as primary so they are used for bidding. Keep softer signals as secondary, where they are reported for insight without steering your bids.
Assign values where you can
For e-commerce, pass the actual transaction value. For lead generation, consider a value based on your average deal size and close rate. Values let you optimise for return, not just volume.
Step 2: Choose your setup method
There are two main routes for website conversions. Both work well; the important thing is to pick one source per action.
Option A: The Google tag
Create a conversion action in Google Ads, then install the Google tag across your site and add an event snippet (or a Google Tag Manager trigger) on the action, such as the thank-you page after a form. This method gives Google Ads its own direct measurement.
Option B: Import GA4 key events
If you already use Google Analytics 4, link it to Google Ads and create Google Ads conversions from GA4 key events. This keeps your goals defined in one place. Be aware that attribution and timing can differ from native Google Ads tags, so compare the numbers before switching bidding over.
Whichever method you choose, check how your site is built. Single-page applications, pop-up forms and third-party booking widgets often need custom triggers; our web design articles cover building sites that are easier to measure.
Step 3: Turn on enhanced conversions
Browser privacy controls and cookie restrictions mean some conversions go unmeasured. According to Google, enhanced conversions supplement your existing tags by sending first-party data, such as an email address, hashed with the one-way SHA256 algorithm before it reaches Google.
Setup can be done through the Google tag, Google Tag Manager or the Google Ads API. Before enabling it, make sure your privacy policy and consent banner cover this use of customer data in your jurisdiction, whether that is a US state or Australia.
Step 4: Test before you trust the data
A tag that is installed is not the same as a tag that works. Run through these checks for every conversion action:
- Submit a real test form or purchase and confirm the thank-you page loads.
- Use Tag Assistant or Tag Manager preview mode to confirm the conversion tag fires once.
- Check the conversion action status in Google Ads; it can take some time to show as recording.
- Confirm the correct value and currency are passed for purchases.
- Verify consent mode behaves as expected when visitors decline cookies.
- Repeat the test on mobile, where forms and layouts often differ.
Keep a simple log of each test with the date and outcome. It makes later troubleshooting much faster, especially after a site redesign.
Common conversion tracking mistakes
Most tracking problems come from a handful of repeat errors. Watch for these:
- Double counting: the same purchase tracked by both a Google Ads tag and a GA4 import, both set as primary.
- Wrong count setting: counting “every” conversion for leads, when “one” is usually more accurate per click.
- Tags on the wrong page: firing on the form page instead of the confirmation page, so visits count as leads.
- Too many primary goals: page views or scroll depth used for bidding alongside real sales.
- Broken after updates: a new theme, plugin or form tool removes the event without anyone noticing.
- Ignoring offline sales: leads that close by phone never feed back into Google Ads.
For businesses that close deals offline, importing those results lets Google optimise for real customers rather than just enquiries. The analysts at Glorvix.com often find this single change improves lead quality more than any keyword tweak.
Keep tracking healthy
Schedule a monthly check that compares Google Ads conversions with your CRM or store orders. Large gaps usually point to a tagging issue rather than a performance change.
The same measurement discipline applies to other channels, as covered in our guide to Facebook ads for small businesses. Browse more PPC guides, or ask the specialists at Glorvix.com to audit your setup. You can also contact our team directly.
Frequently asked questions
Should I use the Google tag or GA4 imports?
Both are valid. The Google tag gives Google Ads its own direct measurement, while GA4 imports keep goals managed in Analytics. Many advertisers use the native tag for primary bidding conversions and GA4 for wider reporting. The key rule is to avoid setting the same action as primary from both sources.
How long until conversions appear in Google Ads?
Conversion data is not always instant. New conversion actions can take some time to show as recording, and conversions are attributed back to the date of the ad click, so recent figures may rise over the following days. Test with a real submission, then check the status column for confirmation.
Are enhanced conversions safe for customer privacy?
Google states that enhanced conversions hash first-party data such as email addresses with SHA256 before it is sent. You remain responsible for complying with privacy laws and your own policies, so update your privacy notice and consent settings, and check the requirements that apply in your US state or in Australia.
Can I track phone calls as conversions?
Yes. Google Ads can track calls from call assets on your ads, calls to a Google forwarding number shown on your website, and clicks on a phone number on mobile. Set a minimum call length that reflects a genuine enquiry so short or accidental calls are not counted as leads.
