AI Alt Text Writing: Making Images Accessible and SEO-Friendly

Alt text (alternative text) describes images for screen readers and search engines. It's both an accessibility requirement and an SEO opportunity. AI makes writing descriptive, keyword-aware alt text scalable across thousands of images.

Why Alt Text Matters

Accessibility: Screen readers rely on alt text to describe images to visually impaired users. Good alt text is an accessibility obligation.

Image SEO: Alt text is the primary way Google understands image content. Well-written alt text helps images rank in Google Image Search.

Content context: Alt text reinforces the topical relevance of your page content, supporting overall page rankings.

AI Alt Text Best Practices

Be descriptive: Describe what's in the image, not just what it represents. 'Bar chart showing SEO traffic growth from 10K to 50K monthly visits over 12 months' beats 'traffic chart.'

Include keywords naturally: If the image relates to your target keyword, include it naturally without keyword stuffing.

Keep it concise: 125 characters or fewer for most images. Longer descriptions should use the longdesc attribute.

Skip decorative images: Purely decorative images should have empty alt attributes (alt="").
