Short Summary Field
The short summary is the compact version of your listing.
Use one sentence that says what the product does and who it helps.
Good:
License and deliver paid WooCommerce extensions without building your own activation server.
Weak:
A powerful tool for modern businesses.
Lyrinox Market uses this field in buyer-facing product details and JSON-LD structured data. When it is empty, the platform falls back to part of the long description, but a written summary is usually cleaner.
Use the description field for the full explanation.
