Hreflang tags on just one page?

Hi there!

There are 3 things to say here:

1. Hreflangs only apply when different pages/domains are copies/translations and carry the same user intent
2. Google understands correctly ccTLD domains, making less necessary to use hreflang
3. Hreflang tag with just self-referential is worthless. Because of 1. and because it need the tag corresponding to the translation page.
   In this case, if you are apllying hreflang to 3 pages, there should be 3 tags.

Also, just for clarifying, take a look at these articles:
Multi-regional and multilingual sites - Google Search Console
International checklist - Moz Blog
Using the correct hreglang tag - Moz Blog
Guide to international website expansion - Moz Blog
Tool for checking hreflang anotations - Moz Blog

Hope it helps.
Best Luck.
