- 
          ValueTrack parameters like {ignore}and{lpurl}can be used with Upgraded URLs to control tracking and crawling behavior.
- 
          The {ignore}parameter indicates that subsequent parts of a final URL do not change content, reducing crawl activity.
- 
          {lpurl},{lpurl+2}, and{lpurl+3}parameters are initialized with the final page URL, with varying levels of escaping.

          For Asset-based extensions, use {extensionid}instead of the deprecated{feeditemid}.
The following ValueTrack parameters can be used with Upgraded URLs:
- {ignore}: This parameter can be inserted in a final URL to indicate that the subsequent part of the URL does not alter content. You can use this parameter to reduce the amount of crawl activity on the URL.- For example, if you have a final URL like: - http://cars.example.com/sedan{ignore}?promocode=NYC123&udv={device}- This tells Google that the content of the page is determined only by - http://cars.example.com/sedanand the page need not be re-crawled for any changes in- promocode, or different instantiations of- {device}.
- {lpurl},- {lpurl+2},- {lpurl+3}: These parameters are initialized with the final page URL, escaped as per standard URL specifications. For example,- {lpurl+2}means the final URL will be escaped twice. If you need the unescaped URL, you can use- {unescapedurl}instead. This is supported only in tracking URLs.
