This is the part of the tracking which is the less possible to standardize as it really depends of many aspects specific to your projects.

Typically, we recommend to leave the data-bx-narrative-group-by with it’s default value ‘id’, unless you are able to define the nature of the value in a clear name.

For example, if you are tracking as value the url of an image (because you do not have any better name/value to provide), then you can set the value of the data-bx-narrative-group-by with “src” or “url” to indicate what it is.

For the value of the data-bx-item-id istelf, we recommend to put a value which is descriptive and easy to read and to use as a group and to only put the specific value as a parameter (with the exception of a price which should be set as the numerical value of the price directly).

For example, for such a case:

we recomend a tracking like :

orange|date=17.02.22

So that you will have easily the reports on all the cases “orange” together and, only for advanced analysis can you go in the decoding and mining of the displayed date.

data-bx-variant-uuid

Typically do not set. Only if you have another tracking system and you would like to inform us of the unique identifier used in the other tracking system
