Why alt text matters for AI search
Alt text isn't just for accessibility anymore. It's a key signal that AI engines use to understand and recommend your content.
AI Engines Read Alt Text
When ChatGPT, Gemini, or Perplexity crawl your site, they use alt text to understand your images. Good alt text = better AI understanding = more mentions.
SEO Ranking Factor
Google still uses alt text as a ranking signal for image search and page relevance. Optimized alt text improves both traditional and AI search visibility.
Accessibility First
Screen readers rely on alt text to describe images to visually impaired users. Good alt text is good UX, and search engines reward it.
Context for AI Crawlers
GPTBot, ClaudeBot, and PerplexityBot all read alt text. Descriptive alt text gives them context about your brand and products.
