Tag every link the same way.

Half of every “(direct) / (none)” row in GA4 is a link someone tagged inconsistently - or not at all. Compose campaign URLs with the exact parameters GA4 reads, encoded and validated, with your last campaign remembered between visits.

Runs entirely in your browser. Your links never leave this page.

Build a tagged link

Composes live. Paste an already-tagged URL and its parameters get lifted into the fields.

Your tagged link appears here.

Presets & discipline.

Two clicks for the common channels, and the naming rules that keep reports readable.

Channel presets

Fills source and medium with the conventional pair; your campaign name stays put.

Taxonomy rules

The five rules that decide whether your reports are readable in six months.

Lowercase, always

GA4 is case-sensitive. Email, EMAIL, and email land as three separate rows in every report, forever.

Hyphens, not spaces

spring-launch survives encoding, copy-paste, and spreadsheets. spring%20launch does not.

source = where, medium = how, campaign = which

newsletter / email / spring-launch reads instantly. Keep each parameter answering exactly one question.

Never tag internal links

A UTM on a link between your own pages overwrites the visitor’s real acquisition source mid-session.

Write the scheme down

One shared page of allowed sources and mediums beats every clever tag. Consistency is the whole game - collected data cannot be retagged.

Sources & methodology.

Every number this tool shows, and where it comes from.

The parameters. utm_source (where the click came from), utm_medium (the channel type), utm_campaign (the specific push), plus optional utm_id, utm_term, and utm_content for manual campaign IDs, paid keywords, and creative variants. Reference: Google’s campaign URL documentation.

How composition works. The tool parses your URL with the browser’s URL API, keeps every existing non-UTM query parameter, replaces any UTM parameters with the field values, and percent-encodes as the spec requires. Paste a pre-tagged link and its UTM values are lifted into the fields so you can see and fix them.

Why medium matters more than it looks. GA4’s default channel grouping buckets traffic by pattern-matching source and medium - email, cpc, social, referral. A misspelled medium lands the whole campaign in “Unassigned,” and collected data cannot be retagged after the fact. Reference: GA4 default channel groups.

Campaign memory. Your last source, medium, and campaign persist in this browser’s localStorage so a batch of links stays consistent across visits. Nothing is sent anywhere; clear your browser storage and it is gone.

What this tool is not. It composes URLs - it does not shorten them, track clicks, or report on results. The tracking happens in your analytics tool; this page just makes sure what arrives there is clean.

Keep measuring.

The rest of the toolkit runs in your browser too.

Discipline is easier when a system carries it

Orbit’s agents handle the repetitive side of go-to-market - CRM upkeep, outreach drafts, follow-ups - with every action staged in an approval queue you control. Consistent tagging is easy once the checklist runs itself.
