ValueTrack parameters dynamically pass information about the source of an ad
click into your landing page URLs. Use the following specialized parameters
when configuring tracking with Upgraded URLs.

- `{ignore}`: Insert this parameter into a final URL to indicate that the
  subsequent part of the URL does not alter page content. Use this
  parameter to help reduce redundant crawling activity on your website.

  For example, consider the following final URL:

      https://cars.example.com/sedan{ignore}?promocode=NYC123&udv={device}

  This tells Google Ads that the content of the page is determined strictly
  by `https://cars.example.com/sedan`, and the page does not need to be
  re-crawled when `promocode` changes or when `{device}` resolves to a
  different device type.
- `{lpurl}`, `{lpurl+2}`, `{lpurl+3}`: These parameters are initialized with
  the final page URL, escaped according to standard URL encoding
  specifications. For example, `{lpurl+2}` escapes the final URL twice. If
  you require the raw, unescaped URL, use `{unescapedlpurl}` instead.

  Note that these parameters are supported only in tracking templates.

> [!NOTE]
> **Note:** Feed-based extensions are deprecated and replaced by [asset-based extensions](https://developers.google.com/google-ads/api/docs/assets/overview). Instead of `{feeditemid}`, use `{extensionid}` to reference an asset-based extension.
