Tag Docket
Request access
For the paid-media teams inside agencies

One way to tag every link. One record of every link you ship.

Tag Docket is the campaign-link registry for agencies. Buyers mint tagged URLs and QR codes from the values the agency approved, on one screen with no wizard and no save dialog, and every link lands in a history the whole team can search.

It replaces the shared spreadsheet of UTM strings, and the GA4 report where facebook, Facebook and fb are three different sources.

The warning arrives before the link ships. The page check found a redirect that would have stripped the tagging off every click. It warns; it never blocks. The buyer decides.

Minted. The destination clears and the taxonomy stays, because the next link is usually the same campaign pointed somewhere else.

What it does

  • Mints tagged links and QR codes from the values your agency approved, lowercased every time
  • Filters out combinations that should never exist, like email traffic from facebook
  • Keeps every link in one searchable history: who made it, when, and where it points now
  • Gives printed pieces a short code you can point somewhere new after they ship
  • Hands a client their whole link history whenever they ask. Export is always free

What it doesn’t

  • Run your ads or log in to your ad accounts. You paste the link where it goes
  • Grant itself access to a client’s GA4. Google requires a person to do that
  • Change a link after it ships. A minted link is frozen, byte for byte
  • Charge per link or per seat. The meter is clients

Monday

Forty links before lunch. None of them typed by hand.

A buyer is building a client’s spring push. She picks Facebook ads and the platform and channel fill themselves; season, offer, service and market come from dropdowns of values the agency approved. The link composes as she goes. After each mint the destination clears and everything else stays put.

When she sets the channel to email, the agency’s pairing rule stops facebook being offered as a source, and the field says which choice narrowed it. The thirty-nine links after that go in as one pasted list, where one bad URL does not hold up the other thirty-eight and a duplicate is caught before it ships.

Wednesday

One of them goes on a yard sign. It gets a short code first.

The same campaign needs a postcard and a sign on the lawn. A printed piece gets a short code, and its QR is drawn from that instead of the full tagged URL. That is not vanity, it is geometry: printed 30 cm wide, the full URL needs a 61×61 grid of 4.92 mm squares. The short link needs 33×33, at 9.09 mm. Bigger squares scan from further down the drive.

Before the print run, Tag Docket reports the grid, the printed width and the module size, and warns when they fall below what print holds. A yard sign gets the highest error correction because it will spend a season in the rain. A link still carrying an unfilled ad macro is refused a QR outright, since nothing fills it in when someone scans a sign.

Friday

The landing page moves. The postcards follow.

The client’s web team renames the page, and the mailer is already in ten thousand letterboxes. Open the link in history, point its code somewhere new, and every printed piece follows. The tagging is not touched, so GA4 goes on seeing one campaign instead of two halves of one.

Codes redirect with a 302, never a 301, so the change reaches phones that scanned last week. A code you are done with is retired, never deleted, and anyone who scans an old print is told the piece is out of service and their phone is fine.

And all week

The client’s GA4 sees one facebook.

GA4 treats Facebook and facebook as two different sources. A real audit of a live property found 13,494 sessions split across social and Social alone.

So Tag Docket lowercases every value, unconditionally, and there is no setting to turn it off. Changing a value later tells you how many links carried the old one before the change lands, and never rewrites a link that already shipped.

The honest comparison

What the spreadsheet does now, and what changes.

Most agencies do not arrive from another tool. They arrive holding a spreadsheet: a tab of UTM strings, a column somebody colour-coded, and a builder page bookmarked by whoever set it up. That is the thing worth comparing against, so here it is, row by row.

The spreadsheet

Someone types "Facebook", someone else types "facebook", and GA4 reports them as two different sources.

With Tag Docket

Values come from an approved list, and everything is lowercased with no setting to turn it off. Impossible combinations, like email traffic from facebook, are filtered out of the builder.

The spreadsheet

A campaign gets renamed in the sheet, and nobody can say which version of the string actually went live.

With Tag Docket

A mint is frozen. The parameters are stored exactly as composed and never recomputed, so renaming a campaign changes how it is displayed and never a string already published.

The spreadsheet

A mailer is in ten thousand letterboxes and the landing page it points at is about to move.

With Tag Docket

A short code for print can be retargeted: the destination moves, the tagging stays, and GA4 keeps seeing the same campaign. A retired code shows a page that says the phone is fine.

The spreadsheet

A copied Meta URL half-works on Snapchat, a macro gets URL-encoded, and nothing looks broken until an ad serves.

With Tag Docket

Platform macros pass through byte for byte, unresolved tokens are checked against the platform’s pack, and every mint records the pack version it was built against.

The spreadsheet

The destination redirects and drops the query string, or already carries its own UTMs, and nobody checks.

With Tag Docket

The landing page is fetched and you are warned — never blocked — when it does not load, redirects, has no analytics tag, or already carries UTM parameters.

The spreadsheet

Finding every link for one client means filtering a sheet with forty tabs and one person who understands it.

With Tag Docket

One always-visible filter row across person, campaign and every dimension, with the filter state in the URL — sharing a view is pasting the address bar.

The spreadsheet

A client moves agencies and their link history stays behind in somebody else’s spreadsheet.

With Tag Docket

The client owns the records about them. Export is always free, and a transfer is approved by the client — the outgoing agency cannot block it, and every frozen mint arrives byte for byte.

Every row on the right is something the product does today. Nothing here is on a roadmap.

“What did we ship for them last spring?” One search.

A spreadsheet can hold the links. It cannot tell you what a colleague shipped last Tuesday, which code is on the postcard about to reprint, or whether the gutters campaign was ever tagged at all. History can: one filter row, always visible, across the campaign string, the destination, the person and every dimension.

The filters live in the address bar, so sharing a view with an account manager is pasting a link. People who have left the agency still appear against the work they did. And the links you import from the old spreadsheet arrive as they ran, with the ones that never matched anything flagged rather than refused.

Who ends up using it

The media buyer shipping forty links before lunch

If minting is slower than typing into the spreadsheet, the spreadsheet wins, whoever signed for the tool. So it is one screen, a preview that updates as you type, warnings beside the field, and a keyboard path from paste to minted.

Starts with the builder and a pasted list.

The agency owner who has to answer for the data

You want every client’s links tagged the same way, a record of who shipped what, and a clean hand-over when a client leaves. You also want the tool to look like yours: paste your website in settings and the app takes on your colour and logo.

Starts by importing the spreadsheet.

Priced by client. Never by link or seat.

Charging per record makes people avoid recording, so the meter is the number of clients. Seats are uncapped and export is always free.

Questions

The ones agencies ask first

Anything else, ask us directly.

How do we get started?
There is no self-serve signup. Request access and tell us about your agency; we set up your organisation, and your team signs in with an emailed link. There are no passwords to create, share or reset.
Do we have to retag everything we already have?
No. Import the spreadsheet you use now. Columns are guessed from the header, and a file holding only the finished tagged URLs works. Links are stored exactly as they ran rather than tidied, because the tidied version would no longer match what GA4 recorded. A row the taxonomy cannot read is still imported, flagged, and nothing is written until you have seen what would be.
Can it connect to a client’s GA4 for us?
It gets as close as Google allows. Granting access is always done by a person, so the app gives you four steps, one address to copy and one button that checks the connection with a real query. Each agency gets its own service account rather than a shared one, and a connection that breaks shows up without anyone having to go looking.
What happens if a client moves to another agency?
The client owns the records about them; your agency keeps the taxonomy and templates it wrote. The new agency requests the transfer and the client approves it at their own address. Every minted link arrives byte for byte, short codes move with it, and you keep a read-only archive that stops counting against your plan.
Does it work with platform macros like {campaignid}?
Yes. Macros for the seven platforms we ship packs for pass through byte for byte, and a token that is neither one of your dimensions nor a macro the platform recognises is flagged before the link is minted. Each link records which pack version it was minted under. The platforms page lists all seven, and says honestly which ones we watch for changes automatically.
Can we use our own short domain?
Not today. Short codes live on app.tagdocket.com/r/ and resolve to the fully tagged URL. Branded short domains are not built, so we do not sell them.

Bring the spreadsheet. We’ll bring the registry.

Tell us about your agency and the clients you tag for. We set up your organisation, and your team signs in with an emailed link.
