> dclid is Google's **display-and-video click identifier** — the DoubleClick / Display & Video 360 (DV360) analog of gclid. Where gclid is for Search Ads, dclid is for display-network and YouTube video ads.

## What dclid actually identifies

Google's Display & Video 360 (formerly DoubleClick Campaign Manager — the “dc” in dclid) runs the display-banner and YouTube-pre-roll side of Google's ad business. Where Search Ads use gclid, DV360 uses dclid: same role (tie the click to the impression, campaign, ad creative), different ad network.

DoubleClick was acquired by Google in 2008 and folded into the Marketing Platform; dclid has carried the “dc” prefix from that era forward.

## Where you'll see it

On display banners served via Google's Display Network, on pre-roll ads served on YouTube and DV360's video supply, and on outbound clicks from those surfaces. Often shows up *alongside* gclid on links that pass through multiple Google ad systems.

## How LinkClean removes it

Default-on in the ads catalog. Same pipeline as gclid, gbraid, wbraid, msclkid, fbclid.

## Example

Looks like this in a URL: `https://example.com/landing?dclid=CKjK8q-abcde12345fghij&utm_source=display&utm_campaign=spring`

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

## Frequently asked

**Why is dclid sometimes alongside gclid?**

When a click passes through more than one Google ad system (e.g. a Display Network banner that's also tied to a Search campaign), both ad networks tag the URL. Both belong to the same advertiser's Google Ads account but feed different attribution reports.

**Is dclid still in use after the DoubleClick rebrand?**

Yes. Display & Video 360 (DV360) inherited the dclid scheme from DoubleClick Campaign Manager. The brand changed; the URL parameter didn't.

**Does dclid carry per-user identity?**

Less than gclid did pre-iOS-14. Today it's largely aggregated for attribution — but still ad-tracking metadata you don't need to forward.
