Shopify SoldOut URL Miner: Export sold-out Shopify product URLs in seconds

I built this after running into the same problem during Shopify SEO audits: sold-out product pages are easy to miss at scale. A store can have hundreds or thousands of products, and manually checking which pages have no available variants is slow and boring. But those pages matter for SEO, UX, crawl cleanup, internal linking, and restock or redirect decisions. So I turned the workflow into a small Chrome extension. It scans public Shopify collection data, checks variant availability, finds products where all variants are sold out, and lets you export the URLs to CSV. This is still a simple MVP, so I’d love feedback from Shopify SEOs, e-commerce teams, and technical SEO people. What should I add next?
