context 7 means Unknown
The seller does not know the content context.
When to send it
Send 7 when the seller cannot tell what the user is doing, such as an ad call from a generic SDK placement with no content metadata.
Most buyers treat 7 the same as an absent Content.context. Leaving the field out says the same thing, but 7 makes the lack of knowledge explicit. It is confused with 6, as described there.
Example
{
"app": {
"content": {
"context": 7
}
}
}Fields that carry it
