UTM Generator — Create UTM Campaign Tracking URLs Instantly
Without UTM parameters, email and social traffic shows up as "direct" in Google Analytics — and campaign attribution is lost. This UTM generator builds correctly formatted utm_source, utm_medium, utm_campaign, utm_term, and utm_content parameters and appends them to your URL. Paste the base URL, fill in campaign fields, copy the tagged link. No signup, no character limit.
What Is UTM Generator?
A UTM generator builds properly formatted UTM parameter strings for tracking marketing campaign traffic in Google Analytics and other analytics platforms. UTM parameters are query string values appended to URLs — utm_source, utm_medium, utm_campaign, and optionally utm_term and utm_content — that tell analytics tools exactly where a visitor came from and which campaign drove the click.
Without UTM parameters, traffic from email campaigns, social media posts, and paid ads often appears as direct or referral traffic with no campaign attribution. Adding UTMs consistently turns that unattributed traffic into actionable campaign data. This tool ensures the parameters are correctly formatted and URL-safe before you add them to any link.
https://example.com
source: google
medium: cpc
campaign: summer→https://example.com?utm_source=google&utm_medium=cpc&utm_campaign=summerKey Features
Builds utm_source, utm_medium, utm_campaign, utm_term, and utm_content — all five official Google Analytics UTM parameters recognized by GA4 and Universal Analytics for session-level attribution.
Spaces and special characters in parameter values are automatically percent-encoded so the URL stays valid and doesn't break when copied, shortened, or shared across platforms.
Output format matches Google Analytics 4's UTM attribution model — utm_source and utm_medium are the primary attribution signals for session-scoped channel grouping in GA4 reports.
The fully built UTM URL is ready to copy without manually assembling the query string — no risk of typos in parameter names or missing ampersands.
When to Use UTM Generator
Use when creating trackable links for email campaigns, social media ads, PPC campaigns, or any traffic source you want to measure in Google Analytics.
Line 1 = your URL. Then one parameter per line as "key: value". Supported keys: source, medium, campaign, term, content. The full UTM URL is generated instantly.

Common Mistakes & Pro Tips
- !Using spaces in UTM parameter values — spaces in UTM values break the URL unless properly encoded as %20 or +. Always use hyphens or underscores as word separators in UTM values (utm_campaign=summer-sale, not utm_campaign=summer sale).
- !Inconsistent capitalization across campaigns — "Email" and "email" in utm_medium create two separate traffic sources in analytics reports. Establish a naming convention (all lowercase is recommended) and apply it consistently across all campaigns.
- !Using campaign-specific values in utm_medium — utm_medium should describe the channel type, not the specific campaign. Correct values: "email", "cpc", "social", "organic", "referral", "display". Incorrect: "mailchimp-october-campaign". The medium is used by GA4 to assign channel groupings (Organic Search, Paid Search, Email, Social). Campaign-specific medium values break cross-campaign channel comparison in analytics reports.
Frequently Asked Questions
Everything you need to know about UTM Generator
What are UTM parameters and why do they matter?
+
UTM (Urchin Tracking Module) parameters are query string tags appended to URLs to track the source, medium, and campaign of website traffic. They are the standard method for attributing traffic to specific marketing campaigns in Google Analytics, GA4, and most other analytics platforms. Without UTMs, clicks from emails and social posts appear as direct or referral traffic with no campaign attribution.
Which UTM parameters are required?
+
utm_source, utm_medium, and utm_campaign are required for basic attribution. utm_term (for paid search keywords) and utm_content (for distinguishing ads or links within the same campaign) are optional. GA4 also supports utm_id for linking to Google Ads campaign IDs. At minimum, always set all three required parameters before publishing any trackable link.
What is the correct UTM naming convention for professional marketing teams?
+
Industry-standard conventions: use all lowercase (GA4 is case-sensitive — "Email" and "email" are different sources); use hyphens not spaces (summer-sale not summer sale); be consistent with utm_medium values — use standard channel names (email, social, cpc, display, affiliate, referral); use utm_content to distinguish A/B creative variants (image-v1 vs text-v2); use utm_term for paid search keywords. Document your convention in a shared spreadsheet to prevent inconsistencies across team members.
How does Google Analytics 4 attribute sessions using UTM parameters?
+
In GA4, UTM parameters set the session's traffic source for session-scoped dimensions. When a user arrives via a UTM-tagged link, GA4 reads utm_source as "Session source", utm_medium as "Session medium", and utm_campaign as "Session campaign". These are stored at the session level, not the event level. If the same user arrives again without UTM parameters, GA4 uses last-non-direct attribution or attributes to Direct if more than 30 minutes have passed since the last session.
How do I track email campaign clicks correctly with UTM parameters?
+
For email campaigns: set utm_source to the email platform or newsletter name (e.g., "mailchimp" or "weekly-newsletter"), utm_medium to "email", utm_campaign to the campaign identifier (e.g., "summer-sale-2026"), and optionally utm_content to distinguish different link placements in the same email (e.g., "header-cta" vs "footer-link"). Build one UTM URL per link placement in the email, then add each tagged URL to the corresponding link in your email editor.
What happens to UTM data when a visitor clicks a shortened link like Bit.ly?
+
When you shorten a UTM-tagged URL with Bit.ly, TinyURL, or a similar service, the full UTM parameters are preserved in the destination URL — the shortener simply redirects to the long UTM URL. GA4 reads the UTM parameters from the final destination page, not from the shortlink itself. Always test that your shortened link redirects to the full UTM-tagged URL before publishing.
Can UTM parameters be used with platforms other than Google Analytics?
+
Yes — UTM parameters are a de facto standard used by most analytics platforms. Mixpanel, Amplitude, HubSpot, Adobe Analytics, Plausible, Fathom, and Matomo all recognize utm_source, utm_medium, utm_campaign, utm_term, and utm_content. The parameter names and attribution model are consistent across platforms, though how each platform groups channels into categories (organic, paid, email, social) may differ slightly in their default configuration.
