Announced a few days ago, advertisers in AdWords can now insert order IDs into conversion tags, which will automatically filter out duplicate conversions from the same device (for example, if a customer books something and then returns to or refreshes the confirmation page). This means that conversion data will be more accurate and you can make better decisions to aid the performance of your campaigns.
Before you get going with the order IDs, there are a few things you need to check:
- Conversion tracking needs to be set up for your website. This seems rather obvious, but you will need to have created a conversion action and added the conversion tag to your website, or else you won’t have anything to use the order IDs on!
- You need to have unique order IDs for your transactions. The order IDs can have numbers, letters, dashes and spaces with a limit of 64 characters – they must be unique for each order. You need to be careful not to include any info that could be used to identify a customer, though.
- You need to have the ability to edit code on your site. You or your web developer will need to edit the conversion tracking tag.
The instructions for adding the code to your conversion tracking tag are available here.
