Your website can look perfect to a human and still make very little sense to AI.
One of the more interesting shifts happening in SEO right now is the growing importance of the accessibility tree.
We usually think about websites through what we see: design, images, buttons, navigation, layout.
AI agents don't necessarily experience the page that way.
They can rely on the structured semantic layer of a website, including headings, landmarks, accessible names, roles, labels, and states to understand what a page contains and what actions are available.
And that creates a new layer of technical SEO.
A CTA might visually say “Book a Consultation”, but if it’s built as a generic with a click handler, an agent may not properly understand it as a button.
A page might have beautiful visual headings, but if they aren't represented as actual headings in the accessibility tree, the content structure becomes much harder for machines to interpret.
The same applies to:
→ generic “Learn more” links
→ unlabeled forms
→ missing image alt text
→ JavaScript content that never reaches the accessibility tree
→ incorrect heading hierarchy
→ interactive elements without clear roles or names
This is where accessibility, technical SEO, and AI search are starting to overlap.
Now we also need to ask:
Can an AI agent actually understand and navigate what we built?
That question is going to become a much bigger part of technical SEO.
