In PrestaShop, Hreflang tags and canonical tags are used to help search engines understand the relationship between different versions of a page on a website.
Hreflang tags are used to indicate to search engines which language a page is written in, and to indicate the relationship between different language versions of the same page. This is particularly useful for e-commerce websites that have pages in multiple languages.
Canonical tags, on the other hand, are used to indicate to search engines which version of a page is the preferred or “canonical” version. This can be useful in situations where a website has multiple pages with very similar or duplicate content.
In PrestaShop, both Hreflang tags and canonical tags can be set up in the back office of the store, through the SEO and URL settings.
PrestaShop also allows users to set up different Hreflang tags and Canonical tags for different languages, which is particularly useful for multilingual e-commerce sites.
In summary, Hreflang tags and canonical tags are used in PrestaShop to help search engines understand the relationship between different languages and versions of a page and to indicate the preferred version of a page, which is useful for multilingual e-commerce sites.
