链接名称
为何重要
A link with no text, alt text or aria-label has no accessible name. Screen readers read out the raw URL or nothing, and search engines lose the anchor-text signal (WCAG 2.4.4).
如何修复
- Add descriptive link text.
- For linked images or icons, add alt text to the image or an aria-label to the link.
使用以下工具检查
- Link Analyzer – List every internal and external link on a page with anchor text and rel attributes.
