2.4.9 Link Purpose (Link Only) (Level AAA)
What it requires: The stricter version of 2.4.4 — link text alone (with no surrounding context needed) has to convey its purpose.
Common failure: Same as 2.4.4’s failure, evaluated without the surrounding-context escape hatch — a “Learn more” link has to be self-explanatory entirely on its own.
Fix it: Make every link’s accessible name fully self-descriptive on its own (e.g., “Shop the Navy Canvas Backpack” rather than relying on context), which also happens to satisfy 2.4.4 automatically.
