Google uses the metadata properties to reconcile the content in your feed with the content in Google's databases; the more metadata you provide for your content, the better Google can match the content.
Highly recommended metadata
There are properties in the documentation that are not listed as required because we understand that you might be missing this information for some content depending on how and where it is sourced. However, as we run evaluations, these fields might become required to help your feed achieve launch quality. Including these properties in the feed is highly recommended to avoid delays in the launch process.
Why are these properties highly recommended?
Google uses the metadata properties to reconcile the content in your feed with the content in Google's databases. A successful match means your title can appear in Google results. Google will not approve your feed if it has too many unsuccessful matches.
The likelihood of a successful match improves both with the completeness and accuracy of the metadata you provide. Properties such as title, description, releaseDate, cast, identifiers, EIDR values are particularly valuable for reconciliation. Though some of these properties are not documented as required, Google may still require you to supply some or all of these for the entities that are not successfully reconciled.
Collect the metadata
Do the following:
- Identify the required and highly recommended properties of your content.
- Gather and organize the metadata information in one place.
