How should you show certifications?
As text with the certifier's name and a link to their directory, not just a badge image.
'USDA Organic,' 'Non-GMO Project Verified' and 'Certified Gluten-Free (GFCO)' are facts assistants can check. A logo in the footer isn't readable. Link to your listing in the certifier's database if there is one.
Do this
- List every certification and its certifying body.
- Add them as text on product pages and in Product schema where it fits.
- Link to the certifier's public listing.
