// Tool 005 · Tracking

Tag a URL or a hundred, the same way every time.

Build clean, lowercase, snake-cased UTMs without retyping the same campaign name into Slack. Single mode for one-offs, Bulk mode for tagging a list. Save templates so the next email blast takes ten seconds.

Inputs

Destination URL ●

The naked URL, with or without existing query params. Existing UTMs will be replaced.

utm_source ●

utm_medium ●

utm_campaign ●

utm_term optional

utm_content optional

utm_id optional, GA4 campaign id

Auto-normalize (lowercase, spaces → underscores, strip punctuation)

Keep existing query params on the URL (only override UTMs)

Saved Templates

Templates are stored in this browser only (localStorage). They don't sync across devices.

Output

// 01

Why normalize?

Google Analytics treats Email, email, and EMAIL as three different sources. Same with spaces vs underscores. Auto-normalize keeps your data tidy without forcing your team to remember the rules.

// 02

Source / medium / campaign

Google requires source and medium for traffic to be classified at all. Campaign is required by convention. Term and content are for paid search keyword reporting and A/B variant tagging respectively. utm_id ties everything to a GA4 campaign object.

Bulk mode pitfalls

If you're tagging affiliate or partner URLs, check that they don't have their own redirect-stripping behavior, otherwise your UTMs vanish on the hop. Test one before sending the batch.
