9. App details
Long-form descriptionAltGuard
AltGuard 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. Keep your store compliant with accessibility standards and boost Google image search rankings easily.
Smart SEO AI & Image Optimizer
Smart SEO covers classic SEO and the new AI search era in one app. AI writes your meta tags, alt text, and product descriptions, and helps you optimize images, page speed, structured data, and broken links. Improve indexing with IndexNow automation, noindex tags, and sitemap control. AEO & GEO tools take you beyond Google: LLM Catalog helps AI assistants discover and recommend your products, while the MCP server lets AI agents analyze your store's visibility and deliver invaluable insights.
