Summary
Website accessibility is crucial for e-commerce success. A study of 50 top sites found low correlation between ranking and accessibility, with contrast errors being the most common issue.
Area of Science:
- Digital Business
- Web Accessibility
- E-commerce Technology
Background:
- Website accessibility significantly impacts e-commerce success.
- Many e-commerce platforms fail to meet accessibility standards.
- Evaluating accessibility is vital for digital business performance.
Purpose of the Study:
- To assess the web accessibility of top-ranked e-commerce websites.
- To identify common accessibility barriers in the e-commerce sector.
- To determine the relationship between website ranking and accessibility.
Main Methods:
- An automatic review method based on a modified Website Accessibility Conformance Evaluation Methodology (WCAG-EM) 1.0 was applied.
- The Web Accessibility Evaluation Tool (WAVE) with a Google Chrome extension was utilized for evaluation.
- Fifty top-ranked e-commerce sites were analyzed.
Main Results:
- A low positive correlation (0.329) was found between e-commerce website ranking and accessibility barriers.
- Contrast errors were the most prevalent accessibility barrier identified.
- The 'perceivable' accessibility principle was the most neglected, affecting 83.1% of sites.
Conclusions:
- E-commerce websites require significant improvements in accessibility, particularly regarding contrast.
- Top-ranking sites still exhibit substantial accessibility issues, impacting user experience.
- Future research should focus on AI-driven tools for automated accessibility barrier identification.
