IxDF Certificate of Completion

[Member name] has mastered how to:

• Build and evaluate web experiences that work reliably for every user and every crawler, combining accessibility, SEO, dynamic interaction design, and usability evaluation into a unified practice.

• Structure web content with valid, semantic markup so that both search engines and assistive technologies can reliably understand and present it.

• Apply progressive enhancement so that pages work dependably for every user, regardless of browser capability, connection speed, or assistive technology.

• Improve search engine rankings through legitimate techniques that avoid search engine penalties.

• Research the terminology users actually search with, so site content and navigation match how users think rather than internal jargon.

• Measure how successfully a site helps users achieve their goals, using conversion data to identify where users abandon their journeys and to evaluate whether design changes have improved outcomes.

• Evaluate products against WCAG using complementary desktop and mobile testing methods, and judge what each method can and cannot reveal.

• Assess the legal risks of inaccessible digital products across jurisdictions, and use WCAG conformance as both prevention and legal defense.

• Design for visual, hearing, motor, and cognitive disabilities, meeting accessibility requirements that go beyond what SEO alone demands.

• Make the human and business case for accessibility by demonstrating that accessible design benefits all users, not only those with disabilities.

• Conduct accessibility audits of live websites and deliver prioritized findings with actionable recommendations.

• Design forms that prevent data entry errors and help users catch any mistakes before submission, improving completion rates and reducing abandonment.

• Build forms that are fully operable by keyboard and compatible with assistive technologies.

• Handle user input flexibly so that valid data is never rejected, and apply current WCAG-required form features that reduce user effort and errors.

• Design the feedback and error handling that asynchronous (AJAX-style) interfaces require.

• Apply perceptual psychology to design and audit dynamic updates that users actually notice.

• Ensure dynamic features fail safely and preserve expected browser navigation behavior.

• Make dynamically updating content accessible to screen reader users through WAI-ARIA.

• Conduct expert heuristic evaluations using Nielsen's 10 usability heuristics, uncovering usability problems quickly and cost-effectively without recruiting users.

• Benchmark designs against structured criteria to track improvement over time, compare against competitors, and demonstrate the business value of UX to stakeholders.

• Plan and run paper prototyping sessions to validate novel design concepts early, before development resources are committed.

• Plan, moderate, and report on usability tests that produce trustworthy, actionable findings, choosing between moderated and unmoderated approaches and scaling participant numbers appropriately.
