Hi! I have a multilingual site with many language-country versions with content tailored to different countries and versions. I am afraid that placing all the hreflang links to the html <head> will influence the page load, LCP, TTFB and so on, so I’m looking into placing the hreflangs to the http headers.
In their documentation Google says that “This is useful for non-HTML files (like PDFs).”
[https://developers.google.com/search/docs/specialty/international/localized-versions#http](https://developers.google.com/search/docs/specialty/international/localized-versions#http)
Can I actually use it not for pdfs but for regular pages as well? Has anyone done something like this?
Thank you!
