Create Google Campaign URLs for Google Analytics & GA4

Google Campaign URLs — also called UTM-tagged tracking links — are the foundation of accurate performance measurement for any campaign running on Google properties, including Google Ads, YouTube, Display Network, and Google Shopping.

Without properly formatted campaign URLs, Google Analytics and GA4 cannot reliably differentiate between your various Google campaigns. Traffic gets merged, attribution becomes murky, and it becomes impossible to know which ad, keyword, or campaign deserves the credit for a conversion.

Proper Google campaign URLs solve this by embedding tracking metadata directly into each link, giving GA4 the information it needs to build accurate, granular campaign reports.

What Is a Google Campaign URL?

A Google campaign URL is a standard destination URL extended with UTM parameters. When a user clicks the link, Google Analytics reads those parameters and attributes the visit to the correct source, medium, and campaign in your reports.

Google originally published the Campaign URL Builder tool as part of its Analytics Help Center. Today, modern marketers use dedicated tools like utmbuilder.click to build Google campaign URLs quickly and at scale.

Here is the structural anatomy of a Google campaign URL:

UTM Parameters for Google Campaign URLs

Google campaign URLs use the same five UTM parameters as all other tracking links, but certain values are specifically relevant to Google Ads and Google Analytics reporting:

utm_source = google

For all campaigns running on Google properties — Search, Display, YouTube, Shopping — the source should always be google. This ensures your Google traffic is grouped correctly in GA4 channel reports.

utm_source=google

utm_medium — Channel Type

The medium value tells GA4 which type of Google channel is sending traffic. Use standardized values that GA4 can correctly classify into its default channel groups:

cpc — Google Search Ads (Pay-Per-Click)
display — Google Display Network banners
video — YouTube video ads
shopping — Google Shopping product campaigns
pmax — Performance Max campaigns

utm_campaign — Campaign Identifier

Name your campaign clearly and consistently. This is the primary filter you will use in GA4 Campaign reports to compare performance. Best practice is to mirror your Google Ads campaign name to maintain alignment between platforms: brand_search_exact, competitor_keywords_q1.

utm_content — Ad Group or Creative Variant

Use utm_content to identify which specific ad group, ad copy variant, or creative performed best. This is especially valuable when running multiple ad variations within the same campaign. Examples: headline_a, responsive_search_v2.

utm_term — Keyword Tracking

For Google Search campaigns, use utm_term to track which specific keyword triggered each ad. You can hard-code a keyword value, or use Google Ads ValueTrack parameters to automatically insert the matched keyword: utm_term={keyword}.

Auto-Tagging vs Manual UTMs in Google Ads

When you connect Google Ads to GA4, you have the option to use auto-tagging (GCLID) or manual UTMs. This is an important distinction:

Method	When to Use
Auto-tagging (GCLID)	When Google Ads and GA4 are linked. GA4 automatically imports campaign data from Google Ads — no manual UTMs needed.
Manual UTMs	When using third-party tracking tools, or when you need UTM data visible in non-Google platforms. Do not use both simultaneously — manual UTMs override auto-tagging.

Google Campaign URL Best Practices

Always Lowercase: GA4 is case-sensitive. Google and google are treated as different sources.
Match Campaign Names to Google Ads: Align your utm_campaign values with the actual campaign names in Google Ads. This simplifies cross-platform reporting.
Do Not Mix Auto-Tagging and Manual UTMs: Pick one approach for Google Ads traffic. Mixing them causes data conflicts in GA4.
Use ValueTrack Parameters for Keywords: Leverage Google Ads ValueTrack parameters like {keyword} and {matchtype} for dynamic, granular tracking.
Use a Campaign URL Builder: Building Google campaign URLs manually at scale introduces errors. Use a dedicated tool to maintain consistency across campaigns.
