Problems with hreflang in products with combinations

[Alternativo]

Good day

We have carried out an SEO audit of the site and we are having problems with the products with combinations, as it indicates that they do not have self-referential hreflang tags.

Can you help us solve this?

Thank you

Hi,
Ensure that the getProductLink method is generating the full URL with the correct language code and combination parameters. If your products with combinations have unique URLs, each combination should have its own self-referential hreflang tag.

Now, Inside the product template, you need to ensure that the hreflang tags are properly generated for each language and each combination of the product. Here's how you can add a self-referential hreflang tag:
{foreach from=$languages item=language}
<link rel="alternate" hreflang="{$language.iso_code}" href="{$link->getProductLink($product.id_product, null, null, null, $language.id_lang)}" />
{/foreach}

Hi, thank you for your answer. Could you specify in which page we should put this code exactly?
