Conversational attributes gained technical names, file-format examples and a TSV feed template

Merchant Center expanded the documentation for its optional conversational attributes, adding the technical attribute name and per-format examples for each one and publishing a TSV template merchants can use to submit them. The attributes are designed to help AI systems and conversational shopping agents understand product nuances that the core product data specification does not cover.

• Attributes now documented with technical names and file-format examples include document_link, question_and_answer, popularity_rank and variant_option.
• The attributes are optional and complement, rather than replace, the primary Merchant Center product data specification.
• Google's help pages are undated; PPC News Feed reported the documentation expansion on 2026-09-16, credited to Hana Kobzová.
