What format should source identifiers use?
Match Booster requires email and other PII to be in a raw, unhashed format. Hightouch then normalizes it—for example, by lowercasing, removing spaces, etc.—to ensure it matches data in our identity graph.
How should I store multiple identifiers of the same type for one user?
The best way to model multiple identifiers of the same type is to consolidate all values in a single row, and to capture multiple entries as an array. If you have just one value per identifier, a string is appropriate.
For example:
| First Name | Phone | uuid | |
|---|---|---|---|
| Tyler | “tyler@work.com” | [”555-123-4567” , “999-555-1234”] | 1 |
| Amina | [”amina@work.com”, “amina@gmail.com”] | ”555-567-8309” | 2 |
Hightouch formats the data to match the requirements of ad platform APIs.
When does enrichment take place? Does Hightouch store a copy of my data?
After you configure match boosting for a model, Hightouch runs a comparison of your selected identifiers against our identity graph and looks for exact matches. Hightouch uses a hashed version of your model's primary key to keep track of and access matched rows. Hightouch never stores any of your proprietary data.
How long does model enrichment take?
Once you've configured your boosted model and selected which identifiers to use for enrichment, you can expect enrichment to take a couple of hours and up to one day. This is true for both the first and subsequent enrichments.
How often do my boosted models refresh?
You can choose how frequently your boosted models are refreshed. By default, after the first enrichment cycle, Hightouch refreshes boosted models every 14 days.
How can I know the last time my boosted model has been refreshed?
You can find the following information in the Match boosting tab of any boosted model's configuration:
- Enrichment Schedule
- Last enrichment
- Next enrichment
Is there a way to manually refresh my boosting?
Yes. Click Save and run enrichment from the Match boosting tab in model configuration.
Should I map the original identifiers I used for enriching my model?
Yes. For example, if you selected email and phone as identifiers for model enrichment, you should also include them in sync configuration.
Hightouch enriches identifier columns you select with additional boosted values.
Why do my match rates appear lower with Match Booster?
Upon the initial sync to an advertising platform, match rates can take up to 48 hours to stabilize depending on the platform. Allow enough time for results to calculate.
Why is Snapchat reporting greater than 100% match?
Snapchat is unconventional in the way it reports match rate. If you send multiple identifiers for the same user, Snapchat initially reports separate matches, which can lead to a greater than 100% match rate. Later, Snapchat deduplicates and resolves multiple matches down to a single user. Check back in a day or two to see the stabilized match rate.
