How to track conversions in Google Ads

Google provides two ways to get conversion actions into Google Ads:

1. By tracking Google Ads conversions directly from your site

2. By linking a Google Analytics account and importing Key Events into Google Ads

Littledata recommends combining both approaches. It includes both the Google Analytics and Google Ads server-side connections in our Google bundle. That means if you use Littledata for Google Analytics, you can connect Google Ads for no additional cost.

Let's start with tracking into Google Ads directly, using primary conversion actions.

Why server-side tracking matters

Traditionally, conversion tracking worked directly between a visitor's browser and Google Ads. When someone clicked an ad and made a purchase, the browser quietly passed that purchase information back to Google. This worked well — until browsers started blocking that kind of data sharing to protect user privacy.

Today, ad blockers and privacy-focused browsers routinely prevent those signals from reaching Google, which means Google Ads can end up with an incomplete picture of what's actually driving sales.

Server-side tracking solves this. Instead of relying on the visitor's browser, the purchase data is sent directly from Shopify's servers to Google Ads — completely bypassing browser restrictions.

How server-side tracking compares to client-side tracking

Here's why that matters in practice:

More accurate conversion data

Because the data travels from Shopify's servers rather than a visitor's browser, ad blockers can't interfere. You get a complete record of every purchase, not just the ones that happened to make it through. That means Google Ads has accurate data to work with when deciding which ads are performing best — reducing wasted spend and improving results over time.

Better matching and audience targeting

Server-side tracking allows Littledata to attach more customer information (securely hashed, so it's never exposed) to each conversion event. Google uses this to better match purchases to the Google accounts of the people who saw your ads — even when cookies are blocked or a customer switches devices. With better matching, Google can correctly credit each touchpoint in the customer journey, helping you understand which ads, audiences, and campaigns are genuinely driving revenue.

This also makes your retargeting more precise. You can build more accurate audience lists for remarketing — such as cart abandoners or lapsed customers — as well as exclusion lists to avoid showing ads to people who've already purchased.

Privacy-friendly by design

Because you control what data is sent and when, server-side tracking makes it easier to comply with privacy regulations like GDPR and CCPA. You can ensure customer data is handled correctly and that consent preferences are respected before anything is shared with Google.

Faster pages

Every script loaded in the browser adds time to your page load. Moving tracking server-side removes those scripts from the visitor's browser entirely, leading to faster-loading pages — especially important on checkout pages, where a slow experience can directly reduce conversion rates.

Benefits of linking Google Analytics

Linking Google Analytics to Google Ads allows you to import Key Events as secondary conversions and sync audiences from Google Analytics for targeting across the full on-site conversion funnel.

You can then:

• Compare the 'greedier' attribution in Google Ads versus the multi-channel, data-driven attribution in Google Analytics

• Report on more ecommerce key events in Google Ads

• See detailed shopping funnel metrics in Google Ads

• Set up more advanced remarketing audiences for abandoned browse or abandoned cart

Choose how to create the audience

You can:

• Create a new audience and define all the rules yourself

• Use a template and adjust the existing rules

• Select a suggested audience and use it as is or modify it

3

Build the audience rules

Use any of the ecommerce events that Littledata sends, or custom dimensions like Customer Lifetime Value (LTV).

Common audience examples:

• Only viewed a product - users who viewed product details but did not add anything to cart in the last 30 days

• Abandoned cart - users who added to cart but did not purchase in the last 30 days

• Purchasers - users who made one or more orders in the last 30 days

Cookie consent & Auto-tagging limitations

GA4 relies on auto-tagging (gclid) and cookies to stitch ad clicks to sessions. But when users block advertising cookies, or when they fail for any reason, the gclid may not persist. In some cases, it may be removed from the URL before it reaches GA4.

A tracking template ensures every ad click appends UTM (ValueTrack) parameters directly to the URL, regardless of cookie status.

One of the best-balanced approaches is to set templates at the account or campaign level. This ensures consistency and avoids conflicts with ad- or ad-group-level overrides. Implementing URL templates alongside auto-tagging creates a robust fallback measurement method for Google Ads.

Removing the Google Ads Link

If you want to remove the Google Ads link, go to Admin > Product Links > Google Ads Links. Click your account, then the three dots in the top-right corner, and select "Delete".
