Parameter: `wt_mc` · Category: Analytics IDs · Vendor: Mapp Intelligence (formerly Webtrekk)

> wt_mc is **the campaign parameter Mapp Intelligence (formerly Webtrekk) reads from a link**. Its value is a media code the sender chose, often dotted, such as `email.newsletter.nov2020.thursday`. The page loads the same without it, and LinkClean strips it on every site.

## What wt_mc is

Mapp's Android SDK has a method that “will track campaign parameters from url”, and it takes an optional media code: “if nil ‘wt_mc’ is used as default”. So `wt_mc` is the name Mapp Intelligence looks for unless a site configures another one.

The SDK's sample link is `?wt_mc=email.newsletter.nov2020.thursday`: a channel, a mailing, a month and a day, joined by dots. The code is the sender's own label, shared by everyone who clicks the same link.

## Mapp and Webtrekk

The same SDK describes itself as integrating “Mapp tracking systems” and says the data goes to “Webtrekk analytic servers”; its code still lives in a package named `webtrekk`. The `wt_` prefix reads as that older name; that is an inference, not something the SDK states.

## How LinkClean removes it

Default-on and global. LinkClean also removes `wt_zmc`, listed beside it. Mapp's SDK does not mention that one, so this page does not explain it. AdGuard's filter strips `wt_mc` as well.

## Example

Looks like this in a URL: `https://example.com/sale?wt_mc=email.newsletter.nov2020.thursday&cat=shoes`

After LinkClean: `https://example.com/sale?cat=shoes`

## Frequently asked

**Who adds wt_mc to a link?**

The company that sent it, when it measures campaigns with Mapp Intelligence (formerly Webtrekk). The value is the media code its marketing team chose.

**Is wt_mc safe to remove?**

Yes. It is read by analytics to file the visit under a campaign. The page does not need it.

**Is wt_mc like utm_campaign?**

It does a similar job for a different analytics product, packed into a single value instead of several tags.
