How to use the conversion tracking code generator for Google Ads

This tool builds Google Ads conversion tracking code with your conversion ID, label, value, currency and transaction ID filled in, and checks code you already use. Every parameter follows Google's Track transaction-specific conversion values and transaction ID help pages.

  1. Enter the conversion ID and label. Both are on the conversion action's Tag setup screen in Google Ads.
  2. Pick the conversion type. A thank-you page, a click on a button or link, or calls from the number on your site.
  3. Choose where it goes. Page code for any site, a ready PHP snippet for WooCommerce, or the field-by-field settings for a Tag Manager tag.
  4. Set value and transaction ID. For sales, read both from the order: the generator writes them as variables, never as fixed text.
  5. Copy, then test. Install the code, place a test order and check the request in Tag Assistant. Paste live code into Check my code to catch broken IDs.

What to do next: install the conversion code

The Google tag belongs on every page. The conversion part only runs where the conversion happens. Pick your setup:

Plain HTML

  1. Paste the Google tag into the <head> of your shared page template, once.
  2. Paste the event snippet into the head of the confirmation page only, below the Google tag.
  3. Have your server define orderTotal and orderId above the event snippet, from the order that was just placed.

Common Google Ads conversion tracking errors

Google Ads conversion tracking not working: no Google tag

The event snippet needs the Google tag on the same page, loaded first. If the Google tag came from Analytics, add gtag('config', 'AW-…') for your Ads account.

Wrong ID or label in send_to

send_to is the conversion ID, a slash and the label of this one action. Copy both from the action's Tag setup screen. The checker flags a missing label and an ID with no matching gtag('config') on the page.

Value as text or with a comma

Google asks you to pass the value as a number with a period as the decimal point: 120.50, not '120,50' or '$120.50'. Keep the currency in its own field.

Static or unfilled transaction IDs

Google lists real-world broken IDs such as {{ order_number }}, <?php echo $order->id; ?>, "thank_you" and "1234". A hard-coded ID means only the first conversion is counted. Print the real order number instead.

Personal data in the transaction ID

Emails, phone numbers and URLs are not allowed. Use the plain order number — the same one you'd use in an offline conversion upload.

Conversions counted twice

Running the gtag snippet and a Tag Manager tag for the same action, or leaving out the transaction ID on a page that gets reloaded, both double count. Keep one setup and always send the ID.

Frequently asked questions

What does Google Ads conversion tracking code look like?

Two parts. The Google tag loads gtag.js on every page. The event snippet runs where the conversion happens: gtag('event', 'conversion', {'send_to': 'AW-123456789/AbC-D_efG-h12', 'value': 120.50, 'currency': 'USD', 'transaction_id': 'ORDER-1001'});.

How do I add a conversion value and currency?

Pass value as a number with a period as the decimal point (120.50, not “120,50”) and currency as a 3-letter ISO 4217 code in single quotes, such as ‘USD’. For values that change per order, set the conversion action to Use different values for each conversion.

What is the transaction ID for and when do I need it?

It stops the same order from counting twice. If two conversions for the same action share a transaction ID, Google Ads treats the second as a duplicate. Use your order number: unique, up to 64 characters, no personal data. Use the same ID in any offline upload of that order.

Where do I find my conversion ID and conversion label?

In Google Ads, open Goals, pick the conversion action under Summary and open Tag setup. The ID starts with AW-; the label is the part after the slash in send_to. The Tag Manager option on that screen shows both as separate fields.

How do I track a button click as a conversion?

Use a click conversion: a gtag_report_conversion() function in the head of the page, and onclick="return gtag_report_conversion('…');" on the link or button. Google says the page must call that function when someone clicks.

Why is my Google Ads conversion tracking not working?

Common causes: the Google tag isn’t on the page, the event runs before it, send_to has the wrong label, or the code sits on a page buyers never reach. Google says the status can take up to 48 hours to update after you install or fix a tag — test with Tag Assistant first.
