UTM Builder for Google Ads
This UTM builder for Google Ads tags your campaign URLs with the GA4-correct source=google and medium=cpc in one click, then URL-encodes every value so your tracking links do not break in the Google Ads editor.
Tag campaign links.
How to use the for google ads
- Paste your ad's landing-page URL into the base URL field; the builder validates that it is a proper http or https link.
- Click the Google Ads preset to set utm_source=google and utm_medium=cpc following GA4 conventions.
- Add a utm_campaign, and optionally utm_content to tell ad variants apart; leave the Clean values toggle on so everything is lowercased with one consistent separator.
- Confirm auto-tagging is OFF for this destination (or that GA cannot read the gclid) so you do not double-count against Google's gclid.
- Copy the tagged URL into your Google Ads final URL suffix, or use bulk mode to tag many ad URLs at once and download a CSV.
About the for google ads
Google Ads is the one channel where "just add UTMs to everything" is bad advice, and this page exists to keep you out of the most common reporting trap. When your Google Ads and GA4 (or Universal Analytics before it) accounts are linked and auto-tagging is on, Google appends a gclid to every ad click and GA reads it directly. GA already knows the click came from google / cpc, which campaign it belongs to, and far more granular detail than a UTM string can hold. Layering manual utm_source and utm_medium on top of that can override the gclid attribution and split one click into conflicting session sources, which is how "double-counting" and inflated paid-search numbers happen. So the honest default is: if auto-tagging is on and GA4 is your reporting tool, you usually do not need UTMs on Google Ads at all. Hit the Google Ads preset on this tool to set source=google and medium=cpc, and use it deliberately for the cases below, not by reflex.
The cases where manual tagging genuinely helps: you are sending clicks to a destination that GA cannot see the gclid in (some email tools, CRMs, third-party landing-page builders, or an analytics platform other than Google), auto-tagging is switched off, or you want a clean, human-readable source/medium in a tool that does not understand gclid. In those situations the google / cpc convention this preset writes is exactly what GA4 expects, so paid search stays grouped correctly instead of scattering into "referral" or "unassigned." The one rule that matters most: never mix manual UTMs with auto-tagging on the same URL unless you have deliberately turned auto-tagging off, because the two systems fight and gclid usually wins in ways you cannot predict.
In Google Ads itself, do not paste tagged links straight into the Final URL field. Put your static UTMs in the account or campaign "final URL suffix," and reserve the tracking template for redirect logic. That is also where Google's ValueTrack parameters live: {campaignid}, {adgroupid}, {keyword}, {network}, {device}, and friends resolve at click time, so you can push dynamic detail into utm_campaign or utm_content without hand-typing it per ad. This builder writes the static, human-decided part of that string, cleanly and consistently, and its Clean values toggle lowercases everything so google and Google never split into two sources; for the taxonomy rules behind that, see the sibling UTM Naming Convention page. It is part of the same UTM Builder that also has presets for Facebook, Email, LinkedIn, and more.
Frequently asked questions
- Should I use UTMs with Google Ads at all?
- Often no. If auto-tagging is on and GA4 is linked, Google's gclid already tells GA the click came from google / cpc with full campaign detail, so manual UTMs are redundant and can conflict. Use manual UTMs mainly when auto-tagging is off, or when a non-Google tool (a CRM, email platform, or third-party analytics) needs a readable source/medium it can actually parse.
- What is the correct UTM source and medium for Google Ads?
- utm_source=google and utm_medium=cpc. This is the GA4 convention that groups the traffic under Paid Search. This tool's Google Ads preset sets both in one click. Avoid variants like medium=ppc or medium=paid, which land in the wrong channel group and force you to write custom channel rules later.
- What is gclid double-counting and how do I avoid it?
- When auto-tagging appends a gclid and you also add a manual utm_source/utm_medium to the same link, the two attribution systems can disagree, splitting one click across two session sources and inflating paid-search figures. Avoid it by choosing one method: keep auto-tagging on and skip manual UTMs, or turn auto-tagging off and tag manually. Never run both on the same URL by accident.
- Where do I put UTMs in Google Ads?
- Not in the Final URL. Add static UTM parameters in the campaign or account 'final URL suffix' field so they persist through redirects, and use the tracking template only for redirect or click-measurement logic. Build the static string here, then paste it into the suffix field.
- Can I use ValueTrack parameters like {campaignid} in my UTMs?
- Yes. Google's ValueTrack parameters ({campaignid}, {adgroupid}, {keyword}, {network}, {device}, {creative}) resolve at click time and can populate utm_campaign or utm_content dynamically. This builder writes the static, human-decided portion; you can append ValueTrack tokens in the final URL suffix so each ad reports its own detail without manual editing.
- How is a UTM different from the gclid Google adds?
- gclid is Google's own encrypted click ID for auto-tagging, read natively by GA and Google Ads for full attribution and conversion import. UTMs are open, human-readable tags that any analytics tool can parse. gclid is richer inside Google's ecosystem; UTMs are portable everywhere else. That difference is exactly why you pick one and avoid stacking them.
- Does this Google Ads UTM builder upload my URLs anywhere?
- No. Everything runs client-side in your browser. Base URLs and values are never uploaded, and your naming preferences (separator and Clean values setting) are saved on-device only. You can also paste many URLs in bulk mode, apply the same google/cpc tags to all, and download a CSV without anything leaving your machine.
- Why should I lowercase my Google Ads UTM values?
- Because GA4 treats CPC and cpc, or Google and google, as different values, which fragments your reports. The Clean values toggle lowercases every value and swaps spaces for your chosen separator, so your paid-search data stays in one clean bucket. The UTM Naming Convention sibling page covers the full taxonomy.
