Introduction to media search and recommendations Stay organized with collections Save and categorize content based on your preferences.

This page introduces and describes the capabilities of Agent Search for media. The page also provides links to more information, tutorials and checklists, to get you started with Agent Search for media.

Agent Search includes two capabilities specific for the media industry:

• Media recommendations. Get recommendations for media content such as videos, news, and music. With media recommendations, audiences can discover more personalized content, like what to watch or read next, with Google-quality results customized using optimization objectives.

• Media search. Get Google-quality search results with advanced query and document understanding designed for media content.

Key features of media apps

There are many similarities between media apps and custom apps in Agent Search. Here are some key features of media apps:

• Media apps require user events. You upload user events to personalize recommendations and rank search results for your audience.

• Media apps require media metadata to conform to a predefined schema or to use a custom schema that contains a minimum set of key properties.

  • Predefined schema. This lets recommendations and search ranking use Google-defined, media-specific fields such as content ratings, aggregated ratings, persons, and production year to help generate results based on media engagement.

  • Custom schema. The custom schema gives you more flexibility than the predefined schema. However, your schema fields must map to the following required key properties: title, category, uri, media_available_time, and media_duration. The category property must be an array of strings, and the other four properties are strings.

    In addition to the required key properties, Google recommends that you map as many other schema fields as possible to the suggested key properties. The suggested key properties represent similar media metadata to that in the predefined schemafor example, content ratings, aggregated ratings, persons, and production year.

• Media recommendations apps offer you a choice of recommendation type. Media recommendations apps let you choose what kind of recommendation to generate, such as recommending other content that users might like, similar items, or the most popular items.

• Media recommendations apps offer you a choice of optimization objectives. For example, you can decide whether to optimize recommendations for click-through-rate to increase the number of interactions with content or for conversion rate to increase the consumption of content.

The following table outlines some functional differences between media and custom data stores.
