About AltMaster: AI Alt Text SEO

AltMaster writes image alt text for your entire catalog with AI that actually reads each image, or a rule-based alt text template built from vendor, title, SKU, and tags if you'd rather skip AI entirely. Run bulk alt text across store images at once. Rename image filenames so both your alt text and image filenames work for product image optimisation, not just one of them. Follow WCAG alt text guidelines.
