Why it matters
Channels increasingly use structured attributes for filtering and shopping experience. product_detail extends the standard field set, letting you encode product-specific specs that influence search relevance for niche queries.
Structured key-value attributes that extend beyond the standard field set. Camera megapixels, fabric blend percentages, screen refresh rates, supplement ingredients — all the product-specific specs that don't fit standard fields but matter for relevance and structured-data results.
The structured format section_name:attribute_name:attribute_value gives the data shape for downstream consumption. Up to 100 entries per item; in practice, 10-20 covers most categories well.
The 2026 strategic angle: AI shopping assistants (Google's AI Overviews, ChatGPT Shopping, Perplexity Shop) consume product_detail extensively for structured answers. "What's the battery life of X?" gets answered from product_detail entries when present. Items with rich product_detail get cited; items without don't.
