Where this fits: accessibility in SEO
Why data table missing caption hurts your rankings
Table captions help all users (including screen reader users) understand the purpose and context of the table before navigating its contents. Without a caption, users must examine the data to determine what the table is about. This is recommended under WCAG 2.1 (Success Criterion 1.3.1).
This is a low-severity issue: a polish item. Fix it in batches during scheduled maintenance; the win is cumulative quality, not a step change.
How to fix it
Add a <caption> element as the first child of the <table> element with a brief description of the table's content and purpose.
