See every featureAltGuard solves the tedious task of manually writing alt text for product images. Without alt text, search engines can't read your images and screen readers cannot navigate your store. AltGuard silently runs in the background. Whenever you add or update a product, our AI analyzes the images and writes accurate alt text. You can also run bulk backfills to update your entire catalog in minutes.
Many Shopify merchants miss out on Google Shopping because structured product data is missing. Image to SEO Fields analyzes your product images with AI and automatically generates optimized titles, descriptions, color, pattern, target audience, and Google product category. You review every suggestion, edit if needed, and decide what gets applied. Output available in English or German.
