Track where your traffic is coming from in Google Analytics

The UTM Builder helps you add tracking parameters to any URL so you can measure performance by channel, campaign, and content variation — without using spreadsheets or manually typing parameters.

You can:

  • Build a single tagged link in seconds
  • Generate multi‑channel campaign URLs at once
  • Create A/B test variants automatically
  • Bulk build UTM links from CSV
  • Extract UTM parameters from existing URLs
  • Export as CSV or JSON

All URL building happens locally in your browser. No links or campaign data are stored.

Why Use a UTM Builder?

If you share links in:

  • Email campaigns
  • Paid social ads
  • Organic social posts
  • Google Ads
  • Blog promotions
  • Retargeting campaigns

You need UTM parameters to understand what’s actually driving traffic and conversions. Without proper tagging, Google Analytics cannot accurately attribute performance.

The Legal Communications UTM Builder ensures every campaign link is consistent, structured, and compliant with GA4 best practices.

Five Ways to Build UTM Links

Single Link Mode

Quickly generate one tagged URL. Perfect for one‑off campaigns or quick link generation.

You can also:

  • Add custom utm_* parameters
  • Generate A/B variants automatically (two links differing only by utm_content)
  • Copy the full URL or just the query string
  • Export as JSON
Field Required
Website URL Required
utm_source Required
utm_medium Required
utm_campaign Required
utm_term Optional
utm_content Optional
utm_id Optional

Multi‑Channel Mode

The tool automatically fills recommended utm_source and utm_medium values for each channel. You receive a full set of tagged URLs instantly — ready to paste into ads, posts, or email platforms. No repetitive data entry required.

Enter your landing page and campaign name once. Then select channels such as:

  • Facebook (Paid or Organic)
  • Instagram (Paid or Organic)
  • LinkedIn (Paid or Organic)
  • Email
  • Google Search
  • YouTube
  • TikTok

CSV Bulk Mode

The tool generates all tagged URLs at once (up to 500 rows per batch). Ideal for agencies, newsletters, or large campaigns. Additional features include:

  • Automatic lowercase formatting
  • Space-to-dash conversion
  • Validation warnings
  • Downloadable CSV output
Field Required
landing_url Required
source Required
medium Required

Import UTMs Mode

This makes it easy to duplicate and modify campaigns without rebuilding links from scratch.

Already have tagged URLs? Paste them in and the tool will:

  • Extract all UTM parameters
  • Display them in structured form
  • Pre-fill Single Link mode for remixing

Settings & Reporting Preview

This helps prevent common tagging mistakes before links go live.

The builder includes:

  • Naming convention guidance
  • Warning summaries
  • A GA4 preview showing how your campaign may appear in analytics

Built-In Validation & Error Warnings

Poorly structured UTMs can break attribution. The UTM Builder automatically flags:

  • Uppercase values (case-sensitive in analytics)
  • Spaces that become %20
  • Special characters outside recommended standards
  • Identical source and medium values
  • Excessively long URLs
  • Invalid URLs (non-http/https)
  • Missing required fields

This ensures your links follow best practices before deployment.

Output & Export Options

All links are generated instantly in your browser. After generating links, you can:

  • Copy the full URL
  • Copy just the query string
  • Export as CSV
  • Export as JSON
  • Download bulk campaign files
