What image SEO issues does CrawlBeacon detect?

It checks for missing alt text, lazy-loading opportunities, markup details, and image signals that affect accessibility, crawlability, and search visibility.

Why is alt text important for SEO?

Alt text helps search engines understand image context and helps screen reader users understand visual content, so it supports both accessibility and image search performance.
