Google does not expose a single \u201cWCAG points\u201d lever in Search ranking, but many accessibility fixes strengthen the same UX signals Google already measures. Teams in India optimising for Hindi SERPs and US teams chasing YMYL queries both benefit when pages become faster, clearer, and more mobile-stable after accessibility remediation.
Indirect boosts you can measure
- Core Web Vitals improve when images carry proper dimensions and lazy-loading is disciplined
- Mobile usability errors drop when tap targets and font scaling issues are fixed
- Structured headings aid featured snippets the same way they aid screen readers
India + US keyword realities
Localised copy with valid lang attributes ranks better in multilingual SERPs and reduces AT confusion. Eliminating overlay interstitials for compliance often removes intrusive interstitial penalties risk while improving bounce metrics.
What not to promise stakeholders
Avoid claiming \u201cSection 508 boosts PageRank.\u201d Instead, report on engagement deltas: time on task, exit rate on checkout, voice-search satisfaction proxies. Pair SEO dashboards with accessibility defect burn-down charts to show correlation.
WCAG version strategy
Align engineering targets with WCAG 2.2 vs 2.1 guidance so marketing microsites inherit the same component library upgrades as compliance-focused domains.
