Google Ads: Conversion Pixel
How to set up the Google Ads Pixel (gtag.js) to track conversions
Setting up Google Ads in ggCheckout:
Google Ads lets you track conversions on your checkout. When a buyer completes a purchase, the conversion event is automatically sent to Google Ads with value, currency, and transaction ID.
Step 1: Get the Conversion ID and Label from Google Ads
In the Google Ads dashboard:
- Go to ads.google.com and sign in
- In the side menu, go to "Goals" → "Summary"
- Click "+ New conversion action" → "Website"
- Select "Create conversion actions manually using code"
- Fill in the name (e.g. "Checkout Purchase"), category (Purchase) and save
- On the next screen, find the snippet with gtag('event', 'conversion', ...)
- The send_to value has the format: AW-123456789/AbCdEfGhIjK
- Before the slash (/) is the Conversion ID, after the slash is the Conversion Label
Step 2: Configure in ggCheckout
In the ggCheckout dashboard:
- Go to "Settings" → "Metrics"
- On the Google Ads card, click "Install" (or "Add another")
- Give the integration a name (e.g. "Main Campaign")
- For Tracking Mode, select "Pixel (Client-side - gtag.js)"
- Paste the Conversion ID (e.g. AW-11468698711)
- Paste the Conversion Label (e.g. FW1mCOf_i4cZENfo2dwq)
- Click "Save"
Step 3: Verify it works
Verification:
- Install the Google Tag Assistant extension in Chrome
- Open your checkout link
- Tag Assistant should show the AW-XXXXXXXXX pixel loaded
- Make a test purchase and check in Google Ads if the conversion was recorded

Important information:
Multiple pixels
Each conversion in Google Ads generates a different Conversion Label, but the Conversion ID is usually the same for the entire account.
Events API mode
In addition to Pixel mode (client-side), ggCheckout also supports Events API mode (server-side via OAuth), which is more reliable as it doesn't depend on the buyer's browser.
Conversion value
The purchase value is automatically sent to Google Ads so it can optimize your campaigns by ROAS.
