Why Use Hreflang Tags?
If you have a multi-language store with pages on different languaes Hreflang tags tell Google and other search engine robots about these different variations. This helps Search Engine to direct users to the most relevant version of your page based on user language or region.
Enable Alternate Hreflang Tags for Magento 2 Home, CMS and Blog Pages
Enabling alternate Hreflang tags on pages is one of the greatest ways to improve Search Engine Optimization. Setting those tags you automatically attract more customers as all of them prefer to be shown or to be led to content on their native languages.
Automatical Hreflangs Tags Generation for Product and Category Pages
After the setting of alternate Hreflang tags configurations, the Hreflang module automatically generated them for catalog Product and Category pages. For the CMS pages, Blog post, and category pages you will need to set an alternative store view versions manually.
Better Store Switcher
Have you been in a situation when visiting a CMS or Blog page you tried to switch the language and were redirected to the homepage or ever seeing 404 error instead of a proper page on the other language? This is common Magento 2 behavior. Alternate Hreflang Tags module fixes this. It has algorithms under the hood that improves the store switching process.
Language And Region Codes
Having plenty of store views in languages that have different region variants ( e.g. American English, British English, Australian English; French in France and Canadian French, etc.) it is hard to differentiate between them and avoid duplicate content problems. Magento Hreflangs extension has an option that allows you to assign a certain store view to the region. I this way you will target the visitor not only by their language but the location too.
Locale Group Definition
Magento 2 Hreflangs plugin enables you to set the locale group you want the website, store or store view to be related to in case you manage multi-website Magento and don’t want the alternate tags to be interconnected between them.
