hi how to add self-referencing hreflang tag to href lang module
bcz This SEO error show on my website
No self-referencing hreflang tag
This is the most common issue in this section. We found out that if a website has a conflict within a page source code, in 96% of cases, the page doesn’t contain a self-referencing hreflang in its set of hreflang attributes. That means that those attributes may be ignored or interpreted incorrectly.
To fix this mistake, make sure to include the page’s URL and language code in your set of hreflang attributes.
