Field facts

Path: app.content.genre, dooh.content.genre, site.content.genre
Object: Content
Type: string
Requirement: Optional
Added: OpenRTB 2.4
Spec section: 3.2.16

How it is used

Because the value is free text, sellers spell genres differently and buyers struggle to target on it. The structured pair Content.genres and Content.gtax was added in 2.6-202501 for that reason. Content.genre is not deprecated, and sellers can send both while partners migrate.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "app": {
    "content": {
      "genre": "documentary"
    }
  }
}

Common mistakes

Packing several genres into one comma-separated string. Send the main genre here and the full set as IDs in Content.genres.
