Markets emits one hreflang tag for every market and language pair, including irrelevant ones. Google indexes these alternates, dilutes the hreflang signal across the catalog, and may serve the wrong version to international visitors. Hreflang Cleaner replaces them with a matrix you control: you check the pairs that make SEO sense, the app injects exactly those tags into the head of every storefront page. Daily bulk sync and storefront health check keep everything in sync.

• One tag per market × language pair — you choose, the app delivers
• Full page coverage — product, collection, cart, search, policies
• Test mode with zero SEO impact — preview before you publish
• Built for large catalogs — tested up to 200,000+ resources
• Daily health check — automatic alert if duplicates appear
