Google Shopping Tracking Product Partition ID Uniqueness

[brett....@ignitionone.com]

Hello,

According to the Value Track documentation, {product_partition_id} is supposed to be unique. However, we are seeing the same partition id being returned for multiple campaigns/clients. 

What can we add to our tracking URL parameters to make this truly unique?

Thanks,

Brett

Just a guess, but could it be unique only within each campaign rather than world unique?

I've noticed the same partition Id being used for the parent product partition in our testing and live accounts.

If that were true then maybe a combination of campaign_id/product_partition_id would work better?

Hi Brett, David,

product_partition_id is the Id of a Criterion. In AdWords, CriterionIds are global. That is, if two criteria have the exact same other properties, they will have the same ID. They are, in fact, the same criterion.

The properties for a ProductPartition are:

• type - always PRODUCT_PARTITION for a ProductPartition
• partitionType - UNIT or SUBDIVISION
• parentCriterionId
• caseValue - a ProductDimension

The root partition of a tree has no parentCriterionId and no caseValue, so there are actually only two root partition criteria - one is a UNIT and one is a SUBDIVISION. This similarly means that the first tier ProductPartitions of a tree will always have the same parentCriterionId - the ID of the SUBDIVISION root criterion.

If you want to be able to tie a partition to a bid, for example, you need to use the AdGroupId to disambiguate. Unfortunately, there is no ValueTrack parameter for AdGroupId.

So is it safe to rely on this? 

Most of our batch jobs send some queries to work out the parentCriterionId of our partition tree. Would we be just as well hardcoding the value? (which seems to always be 18283950120)

Hi Matt, Thank you for your response. I work with Brett and we are trying to determine how we can know the uniqueness of a criterion at the time of click so that we can map back to reports upstream and tie them to the correct group/campaign. The Value Track documentation is a bit unclear as to whether the tradtional KW-target value track params are available to Shopping URLs. Specifically, I am looking for the {creative} param to be available and if that is the same kind of ID on Google's end. If it is, then this could solve our conundrum. Thanks so much.

This has been the case for criteria in general for a long time. However, it is an implementation detail and I would not be comfortable relying on it indefinitely. I'm not sure how best to advise you on the level of risk.

Hi Allison,

Yes, the general parameters should work with any campaign, so you should be able to use the {creative} template.

Cheers,

Mat
