Hreflang issue

[pujarichestsoft]

Is this correct to use the homepage as a default value in a service page HrefLang?

<link rel="alternate" hreflang="x-default" href="https://abc.com/" />
<link rel="alternate" href="https://abc.com/fr/category/service/" hreflang="fr" />
<link rel="alternate" href="https://abc.com/category/service/" hreflang="en" />


Pls help me understand this.

Hreflang issues are almost always caused by a mismatch in either the declaration or the return tags between pages.

You need to meticulously check three things:
- Ensure every language page correctly points to itself and all corresponding alternative language pages using the canonical tag and hreflang tag.
- Verify the two-letter language code (lang-code) and country code (lang-country) are correct (e.g., en-US, es-ES).
- Confirm that all returning pages contain the exact same set of hreflang tags, forming a perfect circular reference loop back to the primary domain.
