Question 1

What is hreflang?

Accepted Answer

hreflang is an HTML attribute that tells search engines which language and regional version of a page to show to users. It prevents duplicate content issues across language versions.

Question 2

What is x-default?

Accepted Answer

x-default tells search engines which page to show when no other language/region matches. It's typically your default or language-selector page.

Question 3

What is bidirectional hreflang?

Accepted Answer

Each page with hreflang must link to ALL alternate versions, and each alternate must link back. If Page A links to Page B with hreflang='en', Page B must also link back to Page A. This is called reciprocity.

Question 4

How many hreflang tags do I need?

Accepted Answer

You need one hreflang tag per language/region variant, plus one for x-default. Each page must include ALL variants including a self-referencing tag.
