Accessibility belongs in SEO and SXO work because it improves the ability of different people to understand, navigate and use a page. Its primary purpose is equal access to content and functions. Better structure, clearer language and more reliable journeys also support search interpretation and conversion.

Use WCAG as a framework for human testing

WCAG 2.2 organizes requirements around content that is perceivable, operable, understandable and robust. Automated tools can find missing attributes and some contrast failures, but they cannot reliably judge alternative-text quality, logical focus order or whether an error message is understandable. WCAG 2.2

Begin with content structure

  • Use one descriptive main heading and a logical heading hierarchy.
  • Write link labels that remain meaningful outside the surrounding sentence.
  • Use lists and tables for their semantic purpose.
  • Declare the page language and mark genuine language changes.
  • Give informative images useful alternative text and decorative images an empty alternative.

Test complete journeys with a keyboard

Navigate the menu, filters, accordions, dialogs, forms and buttons without a mouse. Focus must remain visible, follow a logical order and never become trapped. Hover-only actions need keyboard and touch equivalents. Test at high zoom and in narrow layouts because visual reflow can change the practical order.

Make forms repairable

Associate every field with a label, explain expected formats and identify errors in words rather than color alone. After submission, announce success clearly or move focus to a useful error summary. Preserve valid entries when one field needs correction.

Treat media and motion deliberately

Provide captions, transcripts or audio description according to the medium and its purpose. Respect reduced-motion preferences, avoid unexpected autoplay and make controls reachable. An image used as a link needs alternative text that describes the destination or action.

Fix shared components first

Audit representative templates with keyboard navigation, a screen reader, zoom and mobile reflow. When a defect appears in a shared navigation, card or form component, correct the component so every page benefits. Our user-experience service can include this testing during design and redesign work.

Practical next step

Complete three essential journeys using only a keyboard at 200% zoom: find an offer, verify a proof point and make contact. Record every hesitation, invisible focus and unclear message. This short test usually gives a more actionable priority list than a single automated score.
