Google Ads Conversion Tracking on Shopify: Setup and Fixes

Shopify shows orders, but Google Ads shows no purchases. Or one order appears in Google Ads as two conversions. Or a conversion action sits on a status such as Misconfigured or Awaiting conversions, and you can't tell whether anything is actually wrong.

These numbers feed automated bidding, so a wrong count costs more than a tidy report: Google says duplicate tags can cause inaccurate report data and problems with ad optimization.

Setting up for the first time? Start with which route fits your store. Something already looks wrong? Go straight to the not-working table, then come back for the fix it names.

Which Route Fits Your Store

Google's pages call it the Google & YouTube app and Shopify's call it a sales channel; it is the same install from the Shopify App Store. Google names it the easiest way to set up conversion tracking on Shopify. Find your row, and the last column takes you to your first step.

Ease of setup isn't the only reason to start here. On the Google & YouTube app, Google's own guidance reads:

What You Need Before You Connect

• A Google Ads account that already exists. Shopify's connection guide requires one before you set up Google Ads through the channel.
• Administrator access. The Google account you connect must be an administrator on that Ads account. If it can't be, Google documents a route inside the channel for you.
• Merchant Center only if you want it. Shopify says you don't need to connect a Merchant Center account when you use only Google Ads and Google Analytics.
• Staff permissions. A staff member installing the channel needs Orders, Products, Marketing, Discounts, Blog posts and pages, Navigation, Manage settings, and Manage and install apps and channels.
• A budget line for ads, not for the channel. As of November 2, 2026, the App Store listing reads “Free to install. Additional charges may apply” and says ad spend is billed directly to your Google Ads account.

Check consent while you are here. Google says that if you use the app for conversion tracking and have set up a consent management platform integrated with Shopify's Customer Privacy API, consent mode should work automatically. Shopify also has a built-in cookie banner, and turning it on and choosing regions is the part to settle first.

Build Your Order of Work

The table above finds one row. This quiz crosses four questions, because what you do first depends on your access, where Google tags live today, what your campaigns bid to, and whether you import GA4 purchases. Each result links to the sections it names, so you can skip the rest; the full sequence is in the setup checklist.

Set Up Tracking Through Google & YouTube

Google's setup page counts five steps; the first four are below, and the fifth is verifying the result. If you already set up measurement another way, Google says to install the app before you reimplement your Google tags. If old tags or live campaigns are in play, the checklist's first two steps come before all of this. If the app detects tags that may require migration, Google says you'll receive an in-app notification with details about how to migrate them.

Install the channel and connect Google Ads

1. In the Shopify App Store, install Google & YouTube: review the list of permissions, then select Install.
2. If the channel isn't connected to Google, select Connect Google account and choose the Google account that owns your Ads account.
3. Go to Sales channels > Google & YouTube. In the Just want to set up Google Ads conversion measurement? section, select Get started. Shopify's steps show a second Get started in a Google Ads section, so select that too if it appears.
4. Under Connect your Google Ads account, select the account from the drop-down and select Connect. Shopify says the IDs listed are those where your Google account is an administrator.

The hint on that screen matters if your account isn't in the list: it says you can skip the connection and select Manage on the next step, which is the conversion ID route.

Channel already installed for a feed or for GA4, and no such banner? Shopify's guide gives a different entry for stores with a Merchant Center account: the Advertise your products with Google Ads banner, then an account choice under Set up your Performance Max campaign, then Connect. That guide, read November 3, 2026, doesn't describe a separate entry for a channel installed only for GA4. Google's pages add two pointers: with the app already installed you'll see a banner in your Overview page to migrate your tags, and you can connect your services on the Overview page.

Google's setup page embeds the short screencast below for setting up through the app. It runs from the Get started banner through the account connection, the event destinations and the Google tag to the channel's Settings tab. If your screen differs, follow the written steps.

Confirm what gets measured

1. Under Measure conversions, read the list of Shopify events and destinations.
2. If you don't want to change anything, select Confirm.
3. To change one, select Manage and the pencil icon next to it. Choose Create a new action in the linked account, Select from linked account or Don't measure in linked account. Select Save for that event, then Save when you are done.
4. Review your events and destinations, then select Confirm.
5. If asked, confirm your enhanced conversions settings. Google notes you may not need this step, depending on your account setup.

In our development store on November 3, 2026, the pending step read Measure conversions; once we skipped the account link it read Confirm conversion event settings, and the dialog Conversion measurement settings. Go by what your own screen says.

Confirm the Google tag and complete setup

1. On the Confirm Google tags step, read the tag listed for each service you connected.
2. If the installed tag is correct, select Confirm.
3. Only if you need a tag by hand: enter the tag in the field under Manually added Google tags, use Add Google tag, then select Save.
4. Select Complete setup.

The installed list reads None in that frame because our development store has no Google Ads account connected. Yours should list a tag for each connected service.

Once Ads is connected, Google puts later edits on the channel's Settings page, under Conversion event settings (another part of the same help page says Customer event settings) and Google tags.

Turn on enhanced conversions

Enhanced conversions supplement your conversion data by sending hashed first-party data to Google. Google says this can improve the accuracy of your measurement and unlock more powerful bidding. If you didn't turn it on when you connected:

1. In the channel, go to the Settings tab. The screencast earlier in this guide ends on this tab.
2. Under Google Ads settings, find Enhanced conversions and select Turn on.
3. Review and agree to the customer data terms.

Google describes this as something you turn on, so check the setting rather than assume it is already active. The search note below records what we checked on the Shopify side.

What Does the Google & YouTube Channel Create?

When you link your Ads account through the channel, Google says a purchase conversion action is created automatically and set as the account default, and the rest are created as secondary actions for observation only.

The difference is practical. Primary actions are reported in the Conversions column and used for bidding, as long as the standard goal they belong to is used for bidding. Secondary actions are for observation, with one exception: a secondary action inside a custom goal is used for bidding.

Google's pages disagree on the defaults. The conversion-actions page above says purchase is the account default and the rest are secondary. Google's setup page, also read November 2, 2026, says purchase, add to cart and checkout started are “the suggested default in Google Ads, and set as the account default.”

Go by your own account: look at which actions it marks as Primary, and if a non-purchase action is Primary with a value, fix that first.

Telling the channel's action from an older or imported one is easier from the channel's side. Its Conversion event settings list which destination each Shopify event feeds; compare that name with the list under Summary, in the Conversions drop-down of the Google Ads Goals menu. Any other purchase action there needs an explanation. The two screens come from Google's written steps and comparing them is our suggestion: with no account connected in our development store, we didn't see a populated list ourselves.

The value the channel sends for a purchase is the subtotal minus discounts, without shipping or taxes; the worked example shows why that won't match your order total.

Conversion IDs Inside the Channel, Tags Outside It

People say “manual tag” for both, and they carry opposite advice. The first part below is a documented part of the channel. The other two are what Google tells you to move away from.

Several accounts, no admin access or Floodlight

1. At the connection step, select Skip account connection. Google's page then has you select Yes, skip.
2. Select Manage and the pencil icon next to the Shopify event you want to send, then check the box Add custom conversion ID/label.
3. Enter the AW-CONVERSION_ID/CONVERSION_LABEL string found in your event snippet. Floodlight takes its own DC- string.
4. Select Save for each event, Save when you finish, review the list, then select Confirm.
5. On the Google tags step, use Add Google tag for any extra tag, select Save, then Confirm and Complete setup.

In our development store on November 3, 2026, with no Google Ads account connected, the field was labelled Custom conversion ID/label. Follow what your own screen shows. Google's Google tag page adds that tags starting with AW- are generally associated with Google Ads accounts.

Google tags in Tag Manager

Google puts the limit down to Shopify platform restrictions: Tag Manager is not able to be set up through the Google & YouTube app. Its advice for a store with Google tags in a container is direct:

Shopify recommends the app for stores replacing a Tag Manager script on the Thank you page, because Google maintains it; Shopify's guide gives a store that already runs a Tag Manager custom pixel a different instruction: update that pixel, an option Shopify says Google doesn't recommend. Whether the container still earns its place for other platforms' tags is the question our Google Tag Manager guide answers first. For those third-party tags, Google recommends working with the respective tag providers. If Tag Manager stays in your setup, Google's check is to confirm that the Conversion Linker tag is set up correctly.

Why not paste the tag into a custom pixel

A gtag snippet in Settings > Customer events looks like a shortcut, since a custom pixel can subscribe to checkout events. What a custom pixel can and can't reach is a Shopify question; whether Google stands behind its tags there is answered plainly:

For Google Ads, Google lists these among the features that may not work correctly from that sandbox:

• Enhanced conversions
• Setting up conversions with a URL
• Conversion verification and troubleshooting
• Phone call conversions
• Cross-domain measurement
• Consent mode URL passthrough

Shopify's position matches: adding and using custom pixels is unsupported by Shopify, though it says you can run Google Tag Manager as a custom pixel. Google says running Tag Manager inside that sandbox is not a supported implementation.

Testing is harder as well. Shopify says Tag Assistant's Troubleshoot tag feature doesn't detect Google tags in a custom pixel, and points to the Shopify Pixel Helper for checking that pixel events load. If campaigns already bid to such a pixel, switch them first.

Why Purchases Get Counted Twice

Google names two causes on its page for stores using the channel:

Only primary actions land in the Conversions column and feed bidding, so a duplicate reaching a primary action changes the number your bidding reads. In our illustration, one purchase worth $120 would show as two conversions and $240 of value. Work through the next four parts in order: the bidding step comes before any tag comes off. Channel not connected yet? Set it up first, because that step needs its Purchase action.

How to see a duplicate in Tag Assistant

1. Disable any ad blockers or other browser extensions.
2. Open Tag Assistant at tagassistant.google.com. Google also recommends installing its free Chrome extension to enable extra features. The first time, click Add Domain, enter your store's URL and click Connect. After that, find your site in the list and click the arrow icon.
3. In the tab Tag Assistant opened on your store, complete the action you are checking. Then click Finish in the pop-up and, back in the Tag Assistant window, click Continue.
4. Click a Google tag to open its Summary, then click the Hits sent tab.
5. Read the boxes. Each is labelled Google Analytics or Google Ads. Google says that if you only have Google Analytics boxes, your site isn't tracking Ads conversions.

This check has limits. If the pop-up doesn't appear at all, Google's duplicate-tracking page says you don't have a Google tag installed on your site, and Google's Tag Assistant help also lists ad blockers, consent tools and iframes among connection problems. Tags inside a custom pixel won't show under Troubleshoot tag, so a clean result doesn't clear them; look under Settings > Customer events as well.

Shopify's own check is browser developer tools: look for multiple requests to the same analytics endpoint during a single page load or event.

One pattern has no official explanation we could find. Merchants have reported two identical Purchase tags from the channel itself for one purchase (forum thread, August 2025), and double conversions with the channel linked (forum thread, May 2025), with no confirmed cause in either. The pages we read don't say whether two hits like that are normal, so don't judge by the hit count alone: place one order from a real ad click and check whether it reaches Google Ads as one conversion or two.

Switch bidding before you remove anything

Google's last setup step runs in this order: check that new campaigns are bidding to the new conversion action and set it as primary, then set up the channel's conversion as primary and remove legacy tags. For a store bidding to custom pixel conversions, it says to switch the conversion action to the one the channel measures.

If campaigns are live, doubled or not, do this before you touch any tag:

1. In Google Ads, open Summary under Conversions in the Goals menu, and find the goal holding the action your campaigns bid to.
2. Check for a non-purchase action, such as Page view or Add to cart, set to Primary with a value. Google says to switch it to Secondary or remove its value to prevent double-counting.
3. Click Edit goal. Under Conversion action optimization, select Primary for the channel's Purchase, then Save.
4. Set the older purchase action to Secondary (observe only) the same way. This is our reading of Google's rule that secondary actions don't drive bidding, and it doesn't hold if a custom goal includes that action.
5. Only now remove the old tag, and only the duplicated events. Google warns that disabling other conversion events can decrease tracking accuracy.

Do it in one sitting. Google says Smart Bidding strategies need a standard 7–14 day learning phase, and that frequent manual changes to conversion goals during it reset the window.

Where Shopify gives both orders, both stand. For additional scripts being replaced with a pixel on a page not yet upgraded, its upgrade page says duplicate events are tracked while both run, and that you can deactivate the script first to prevent them. Its page on replacing a Tag Manager script has you deactivate once the pixels are confirmed working.

Its migration guide gives the same choice for a new custom pixel: connect first to minimize missed events, or remove the old pixel first to avoid duplicates. Neither changes where bidding sits while you do it.

The four places Google names, and how to clear each

Google's removal page says it is crucial to remove previously installed duplicate tags once your store has migrated to the channel. If Customer events is unavailable to you, that is a permissions question: why Customer events can be greyed out.

The second row may not exist for you. Non-Plus stores had until August 26, 2026 to upgrade their Thank you and Order status pages, and Shopify says stores not upgraded by then were upgraded automatically.

Shopify's pixel migration page names leftover code in Additional scripts and checkout.liquid as a cause of duplicates. If your Settings > Checkout screen lists a script that duplicates a Google tag and your Thank you page isn't upgraded yet, disable that script.

Old Add to cart and Begin checkout tags go the same way. Google's look-for list isn't limited to purchases: it covers any script containing gtag('event'…). The channel creates its own Add to cart and Begin checkout actions as secondary, so an old snippet for the same event can be a duplicate once the channel measures it. Check first that no campaign still depends on the older action, then remove only those events.

Google's list also includes Tag Manager snippets in both Liquid files, which is the Tag Manager decision above in another form. Shopify's own wording is wider than the four places: the same event can be tracked in more than one place, such as your theme code, an app, or Customer events. So after you clear the four, recheck for an app sending its own tag.

A GA4 purchase imported beside the channel's Purchase

Google's import page says you can use any combination of imported Analytics conversions and Google Ads conversion measurement at the same time. Shopify's GA4 migration guide includes an import step for stores that once tracked Ads conversions through Universal Analytics, with no warning about duplicates. Google's Shopify tag page does tell you to check how to avoid duplicating tracking events if you plan to use Analytics for conversions.

Google states the principle, not this pair. Its page on conversions based on Analytics key events says they are set as secondary “to prevent counting the same event twice for bidding.” The next step is our reading: the Conversions column shows only actions set as Primary, so if an imported purchase is switched to Primary beside the channel's Purchase, one order can reach that column twice. A transaction ID doesn't obviously rescue this, because Google's duplicate rule speaks of two conversions for the same conversion action, and these are two actions.

The practical move: keep one purchase action Primary and leave the other Secondary, where it still reports under All conversions. The pages we read don't say which to keep. We'd keep the channel's, because it is the route Google recommends. Connecting GA4 itself is a separate job, covered in how to add GA4 to Shopify.

How to Check That Conversions Are Recording

Google says you can view conversion action statuses in the Summary section of the Conversions page, and that if your conversion action table shows Unverified, Tag inactive or Needs attention, you can use Tag Assistant to verify the action.

What each status means

Two Google pages give different windows for Tag inactive. The second page linked under the table says 7–14 days; another page, read the same day, says Google no longer sees your tag and has recorded no conversions in the last 7 days. Don't wait for either number to settle it: verify the action in Tag Assistant, which tells you whether the tag fires.

Run a test that can actually show up

A direct order on your own store is the obvious test, and Google is specific about why it can mislead you:

1. In Tag Assistant, start from a landing page or your home page rather than the conversion page URL.
2. Complete the conversion and finish the session. Actions verified there update in Google Ads after approximately 30 minutes.
3. For the end-to-end check, click a real ad and complete a conversion. Google says the conversion will appear within the next few hours. It also says you'll be charged for the click, which is why it prefers Tag Assistant or waiting for a conversion from an ad click.
4. Check that new campaigns are bidding to the new conversion action.

Google's timings depend on what just happened:

The Setup Checklist

The first two steps change nothing, and they are what make the rest safe. Step six comes before step seven on every route. If you are adding conversion IDs by hand, step four is where you skip the connection; the others stay the same.

Google Ads Conversion Tracking Not Working on Shopify

If you can see the action in Google Ads, start with what its status means, using Google's own definitions. The table below starts from what you are seeing instead.

Where to take it next. Shopify says that for issues related to Google Ads, account suspensions or ad approvals, you need to contact Google directly. Google's check for third-party platforms such as Shopify is that they have the correct Google conversion ID and label integrated, and for inactive tags, to verify the setup in Tag Assistant.

Why Google Ads and Shopify Show Different Numbers

Before you treat a gap as a tracking fault, rule out the differences Google documents:

• Which date a conversion lands on. Google's discrepancy page says Google Ads reports conversions on the ad impression date, while other reporting tools use the conversion date. Its import page puts it as the date and time of the click.
• How long a conversion can still arrive. Conversions can be reported up to 90 days after the click, so recent days can still move.
• Cookie windows, if you also compare GA4. Google Ads cookies expire 90 days after a click, while Analytics uses a cookie lasting up to 2 years.

For closer alignment, Google suggests adding the Conversions (by conv. time) or All conv. (by conv. time) columns to your reports. How Shopify credits campaigns in its own reports is a separate question, covered in our guide to Shopify's Marketing reports.

What the purchase value counts

Google's event reference says that, starting April 24, 2025, purchase values reported by Google tags loaded through the channel take discounts into account, and that the value doesn't include shipping charges and taxes.

Here is what that does to one order, using amounts we made up for illustration rather than figures from Google or Shopify. A customer buys $140 of products with a $20 discount, pays $9 shipping and $6 tax. Google Ads receives a value of $120 ($140 − $20). Shopify shows an order total of $135 ($120 + $9 + $6). Those two numbers are both correct.

If that same purchase were counted twice, Google Ads would show two conversions and $240 ($120 × 2), which no shipping or tax difference explains.

The Bottom Line

The risk here sits mostly in the order of the work. Cleaning up what was already running is where a store can pull a tag its bidding still relies on, or leave two tags reporting one purchase.
