About Image Alt Setter
From the official readme · v1.4Description
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.
