Bulk Update Keyword Research Items

Updates multiple keyword research items.

This method has no field mask and writes every field present on each entry. keyword and mainKeyword remain the only writable fields, and mainKeyword only promotes, as it does for a single item. Repeating an item ID within one call is rejected.

Validation runs across the whole request before anything is written, so a problem rejects the entire call rather than failing one entry. Every returned entry therefore reports success.

A keyword research holds at most 30 keywords, counted after the update. That limit is reached well before the request's own item limit.

This method copies AI-generated research the same way a single-item update does, so send the keywordResearchId from the response on your next write. Edits don't survive a later generation.

To update a single keyword research item, call Update Keyword Research Item.
