Description
Erdo Image Optimizer is not just another compression tool; it is a comprehensive Image SEO & Performance Suite. While most plugins only focus on file size, we bridge the gap between performance and search engine visibility.
Our unique «Image SEO Auditor» scans your entire media library and provides a professional health score (0/6) for every single image. We help you identify and fix the most common SEO mistakes that developers often overlook, such as messy filenames, missing alt texts, and incorrect titles.
