Why Alt Text Matters for SEO and Accessibility
Alt text (alternative text) describes images for users who cannot see them, including those using screen readers and search engine crawlers. While not a direct ranking factor, descriptive alt text helps search engines understand image content and can improve image search rankings.
Best practices include being descriptive but concise (under 125 characters), avoiding keyword stuffing, and ensuring the alt text provides value if the image fails to load. Use natural language and focus on the image's purpose and content.
