I write the question after to search through the forum so I didn't find anything related.
I don't really know how to use the tag to avoid duplicate content issues on the next case:
- 5 different sites with the same content, same language but different domains and for different countries:
Should I use Hreflang in this case? As far I know hreflang is for same domain with different languages but it is also for this case?
Thank you and I hope someone can clarify it!
