Google Ads conversions missing

Introduction

If you're running Google Ads for your Shopify or ecommerce store and notice that conversions are missing or not tracking correctly, you're not alone. This is a common issue that can lead to inaccurate reporting and wasted ad spend. Understanding the root causes and how to troubleshoot them is essential for accurate performance measurement and optimization.

Why This Issue Happens

Missing Google Ads conversions usually stem from technical tracking problems between your website, Shopify, and Google Ads. These issues can prevent conversion data from being sent or recorded properly in your Google Ads account.

Common Causes

Incorrect or missing Google Ads conversion tracking code on the thank you/confirmation page
Improper setup of Google Tag Manager (GTM) or conflicting tags
Browser privacy settings or ad blockers blocking tracking scripts
Duplicate or multiple conversion tags firing, causing data discrepancies
Shopify checkout settings not supporting custom scripts (Shopify Plus vs. standard)
Changes to the website theme or checkout process that remove or break tracking scripts
Incorrect conversion action settings in Google Ads (e.g., wrong URL, event type, or attribution window)
Delayed or missing order confirmation page loads (e.g., customer closes browser early)

Step-by-Step Checklist to Fix It

Check if the Google Ads conversion tag or GTM container is present on your order confirmation/thank you page.
In Shopify, go to Settings > Checkout and verify that your tracking scripts are installed in the "Order status page" field (for non-Plus stores).
For Shopify Plus, ensure the script is in the checkout.liquid or post-purchase scripts section.
Use the Google Tag Assistant or Chrome Developer Tools to confirm the conversion tag fires after a test purchase.
Review your Google Ads account: Go to Tools > Conversions and check that the correct conversion action is active and properly configured.
Check for duplicate tags or conflicting scripts in GTM or Shopify’s theme files.
Test with browser extensions and ad blockers disabled to see if the issue is related to user privacy tools.
Ensure you’re not using both native Shopify Google Channel and manual conversion tags at the same time, which can cause double-counting or missed conversions.
Wait 24 hours after making changes, as conversion data can be delayed in Google Ads reporting.

What Does NOT Work

Simply reinstalling the Google Channel app without checking tag placement or settings
Relying solely on third-party Shopify apps for conversion tracking without verifying Google Ads integration
Ignoring browser privacy updates—these can impact tracking regardless of script placement
Assuming that Google Analytics conversions are the same as Google Ads conversions (they use different attribution models and scripts)

How Reviews or Checks Work

Google does not manually review your conversion tracking setup unless you request support. Most checks are automated. You can self-review by using tools like Google Tag Assistant, or by checking the "Status" column in your Google Ads conversion actions. If Google detects a tag is not firing, you may see a warning or "No recent conversions" message.

FAQ

Why are my Google Ads conversions showing as zero, but I have sales?
This usually means the conversion tag is not firing on the order confirmation page, or it’s not set up correctly in Google Ads.
Can I use Google Analytics conversions for Google Ads optimization?
You can import Analytics conversions into Google Ads, but native Google Ads conversion tracking is more reliable for ad optimization.
How do I test if my conversion tracking is working?
Make a test purchase and use Google Tag Assistant or Chrome Developer Tools to confirm the conversion tag fires on the thank you page.
Do changes in my Shopify theme affect conversion tracking?
Yes, updating or changing your theme can remove or break tracking scripts. Always re-check your tracking after making theme changes.
How long does it take for conversions to show in Google Ads?
Conversion data can take up to 24 hours to appear in your Google Ads account after a successful tag fire.
