I have a multilingual static website; the pages of each language live in specific sub-folders such as / en, / es, / fr, etc.
What should I think about in terms of SEO for this index page?
- Should I add hreflang attributes pointing to the index page in the language-specific subfolders?
- What should I add as x-default? One of the language-specific index pages, or the "language detection" page itself (which has no actual content ..)
- Should I add a robots meta tag?
