Content campaigns hit a wall on empty markup
Generative search and answer engines still retrieve documents. Pages with one giant div, no heading outline, unlabeled fields, and no document language are harder for assistive tech and for extractors alike.
Shipping more AI-written articles does not fix a homepage input that only has a placeholder, or an h1 that skips to h3. Those are AHQ-A11Y and SEO outline problems on the same HTML.
Overlaps that are worth one backlog
One clear h1 and consecutive headings — outline for users and for section extraction. Meaningful link text instead of “click here” — usable out of context and better anchors. lang on html — pronunciation for screen readers and language hints for machines. Captions tracks and alt attributes — media understanding beyond CSS.
AuditHQ keeps accessibility in its own Lab group so you can prioritize WCAG-shaped fails without mixing them into Best practices security rows — but the remediation still lands in the same deploy as SEO fixes.
What not to confuse with AI Overviews hacks
Google’s guidance still favors crawlable, authoritative HTML over special AI-only files. Accessibility work is that crawlable HTML — not a substitute for topical depth, and not a reason to invent mention schemes.
Use the AI-ready score for agent reachability (bots, Markdown mirrors, llms.txt). Use AHQ-A11Y for human-and-machine structure. Use SEO panels for indexability. Three lenses, one site.
