# Link retargeting

> Build retargeting audiences from any link — even links to sites you don't own — with a consent-first interstitial.

Link retargeting lets you fire your ad platforms' pixels when someone clicks a TrackRev link, so
you can build retargeting audiences **even from links to sites you don't control** — a podcast
page, a marketplace listing, a press article. Clicks pass through a brief consent interstitial
that fires your pixels only after the visitor agrees, then continues to the destination.

## How it works

<Steps>
  <Step title="Configure your pixel IDs once">
    Go to **Configuration → Integrations → 6 · Retargeting pixels** and add the IDs for the ad
    platforms you use (see [supported providers](#supported-providers)).
  </Step>

  <Step title="Enable retargeting on a link">
    When creating a campaign, expand **+ Add retargeting pixels** and tick *"Enable link
    retargeting for this campaign"*.
  </Step>

  <Step title="Clicks pass through a consent interstitial">
    A real human clicking the link sees a short *"Taking you to {destination}"* screen with
    **Allow & continue** and **Continue without** buttons. On allow, your pixels fire and the
    visitor continues. On decline, nothing fires and they continue immediately.
  </Step>
</Steps>

## Supported providers

| Provider             | ID format                   | Where to find it                              |
| -------------------- | --------------------------- | --------------------------------------------- |
| **Meta Pixel**       | `1234567890123456` (digits) | Events Manager → Data sources → your pixel ID |
| **Google Ads**       | `AW-123456789`              | Google Ads → Tools → Google tag               |
| **LinkedIn Insight** | `1234567` (partner ID)      | Campaign Manager → Analyze → Insight Tag      |

<Note>
  You enter **IDs only** — TrackRev injects each platform's official loader for you and validates
  the ID format, so no arbitrary markup ever reaches the interstitial.
</Note>

## Consent behaviour

* A visitor's choice is remembered for **180 days**. Once someone allows, returning clicks fire
  pixels automatically (a quick spinner, then continue); once someone declines, they're never
  interrupted again.
* Bots, link-preview crawlers and visitors with JavaScript disabled always pass straight through
  and never fire a pixel.
* If you haven't configured any pixel IDs, retargeting-enabled links simply pass through with
  nothing to fire.

<Tip>
  Retargeting is ideal for links you share to **destinations you can't add a pixel to**. For your
  own site, the [TrackRev pixel](/getting-started/install-pixel) already tracks everything —
  retargeting just adds your ad platforms' audiences on top.
