Google has introduced “order IDs” that can be added to conversion tracking tags. The update means that unique order IDs can be added as identifiers to conversion tags on so-called conversion pages, such as a booking confirmation page. In practice, this means that if a user refreshes or returns to their unique conversion page, Google will know that it is a duplicate conversion and will not count it as a separate conversion, thereby giving more accurate conversion metrics. Webmasters can add order IDs by amending parts of the HTML code of their AdWords conversion tracking tag on their website. Â
