Parameter: `ttclid` · Category: Ad-click identifiers · Vendor: TikTok Ads

> ttclid is TikTok Ads' per-click identifier — added to outbound links from TikTok ads to credit ad spend. Forwarding it carries TikTok's attribution token into someone else's browser. Strip it.

## What ttclid does

When you click a link inside TikTok or an outbound TikTok Ad, TikTok appends ?ttclid=<opaque token> to the destination URL. The token ties that click back to the ad impression, the advertiser, and (where TikTok still has a cookie / IDFA) your TikTok identity.

On the destination, the TikTok Pixel (or the server-side Events API) reads ttclid and reports the click back to TikTok for conversion attribution. Same architecture as Meta Pixel + fbclid.

## Plus _ttp

TikTok also drops a _ttp parameter alongside ttclid in some flows — it mirrors a cookie the TikTok Pixel reads to bridge browsers that don't accept third-party cookies. LinkClean strips _ttp too.

## How LinkClean removes it

ttclid and _ttp both ship default-on in LinkClean's ads catalog. Same pipeline as fbclid, gclid, msclkid, yclid — vendor-specific tokens with no legitimate non-tracking use anywhere on the web.

## Example

Looks like this in a URL: `https://example.com/product?ttclid=E.C.P.aabbccddeeff112233445566778899`

After LinkClean: `https://example.com/product`

## Frequently asked

**Does removing ttclid break the link?**

No. The destination page never reads it — only the TikTok Pixel does, and that's TikTok's bookkeeping, not yours.

**Is ttclid personal data?**

It can be joined back to your TikTok session on TikTok's side, so for them, yes — they know which click it was. The URL itself doesn't name you.

**What about _ttp?**

_ttp is TikTok's cookie-mirroring URL parameter — it carries the Pixel's first-party cookie ID across browsers that block third-party cookies. LinkClean strips it too.
