Entering the value into AHS
Once you have copied the Attribution tag from the Amazon ads/marketing portal, you may either add a brand new link to the book you want to place the tag on, or you can edit an existing link on the ad.
Note: If you edit an existing link and save it, the next person who clicks that link (i.e. from a Facebook ad) will be using the Attribution tag version of your link. That means you don’t have to republish your links everywhere. Just make the change and they will automatically start using the Attribution tags.
