About this plugin
Image Alt Setter is a lightweight and powerful WordPress plugin that automatically sets missing image alternative text (ALT text) across your website.
ALT text is critical for website accessibility, SEO rankings, and overall content optimization. However, many WordPress websites contain hundreds or even thousands of images without proper alternative text. Manually updating them can be time-consuming and frustrating.
This plugin solves that problem instantly.
Image Alt Setter automatically detects images that do not have alternative text and assigns the image title as the ALT text. This ensures that every image on your website has meaningful alternative text without requiring manual effort.
Perfect for bloggers, agencies, WooCommerce stores, news websites, and SEO professionals.
Why ALT Text Is Important
Alternative text is essential for:
• Improving WordPress SEO
• Helping search engines understand your images
• Increasing visibility in Google Image Search
• Enhancing website accessibility for screen readers
• Improving user experience for visually impaired visitors
• Supporting WCAG accessibility guidelines
Search engines rely heavily on ALT text to understand image context. Missing ALT attributes can negatively affect your SEO performance and accessibility score.
