hreflang="tl"

tl is a valid hreflang value for Tagalog.

Language: Tagalog (tl, ISO 639-1)

Example

<link rel="alternate" hreflang="tl" href="https://example.com/tl/" />

The code is case-insensitive for Google. The conventional spelling is a lowercase language, a title-case script and an uppercase region: tl.

Without a region, the annotation targets every Tagalog speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
