4.6 Agentic readiness (Lever 9) ✦HighInferred
Primary content absent from accessibility tree
If the main content does not appear in the accessibility tree, often due to custom widgets or canvas rendering, agents and screen readers cannot reach it at all.
What it is
Core content not exposed to AT/agents.
Why it matters
Agents (and assistive tech) can’t perceive it.
How to fix it
Use semantic HTML so content is exposed.
How to find it on your site
- Check that the primary content is present in the accessibility tree.
- Identify content rendered in ways that bypass semantics.
- Re-implement it with accessible, semantic markup.
- Verify the content is now exposed.
Cross-reference to ranking and citation factors
Primary content missing from the tree is invisible to agents and assistive tech. Exposing it is essential for agentic readiness.
Impact
Medium for agents/a11y. Inferred.
