This is a great app that takes care of a notoriously tricky aspect of the implementation. It does exactly what is required for implementing and managing hreflang tags. If you have any issues, support will promptly investigate and fix them. 

We are very happy with Digital Darts: Hreflang Tags and can only recommend it if you have multiple shopify stores. Thanks to Joshua for the great support

Hreflang Tags is a great app! They've made what's normally a complex setup, very easy and straightforward. The out of the box mapping by SKU saves so much time as well. Their support is very fast and helpful every time. Thank you!

We have separate stores in bi-lingual countries and stores in the same language across specific ccTLD's. This makes it hard to implement correct href lang tags in shopify. This app solves the problem. It's basically very user friendly. There were a few issues setting it up but the support was great and everything was set up correctly for us. Very happy with this solution.

Great tool, and completely necessary if you're forced to run multiple Shopify instances. We saw significant improvements in our search rankings and traffic within days of installing the app. It's easy and straightforward to use, and works reliably. No complaints!

Easy to setup & maintain - also for Non-Coders like me. Still not 100% sure if everything is working as expected though, but better than doing nothing about Hreflang Tags or having to custom develop a similar solution.

As an ecommerce store owner there is always a million and one things worry about, by installing the Multi-Store Hreflang Tags app it takes all the hassle out of doing work manually and I can be confident that my Hreflang tags are implemented correctly and following googles best practices.

This app is exactly what I needed. It's easy to set the hreflang tags, you can combine different stores and it is compatible with Shopify Markets. The support is great too. Absolutely recommendable.

We have a lot of different stores, so it is quite difficult to set up correct hreflang tags. This app helped us a lot to simplify the process of creating, managing, and ensuring correct hreflang tags at all times. The setup is very simple and the support team is great! They are constantly trying to improve the app and even implemented a new feature which we suggested. Would recommend it to everyone!
