When you are creating dynamic ads, all dynamic elements will have to be assigned a reference name and index number. Below, you will find a short description of both the reference and index to clarify what they represent and how they are used in Bannerwise.
Reference corresponds with the columns or keys in your feed. Examples are imageUrl, description, and price. Because you have mapped your feed, the options to add a reference to an image element are limited to your mapping settings. Selecting a reference will align a banner element with the content of the corresponding column in your feed.
If you have multiple elements in your banner with the same reference, Index becomes important. Two dynamic elements with the same reference can never have the same index, because it will cause the banner to pull the exact same values from your feed (e.g. you will end up with two product images that are the same). This way Bannerwise helps you to select a different index for every additional banner element with the same reference.
The value Index will also correspond with the hierarchy in your campaign. Let’s say you want to retarget your audience with the products from their shopping cart and your banner will show three products. The rulings in your campaign settings will define which product is most relevant, which one is the second relevant, and so on. The Index value will correspond with these rulings: Index 1 will pull the most relevant article from the feed, Index 2 will pull the second most relevant article from the feed, etc.
Make sure that related elements all have the same index: Product A with Index 1 should be accompanied by a price with Index 1 and a name with Index 1.
