Which HTML tag is commonly used to indicate the preferred version of a page when multiple language variants exist?

• A. Robots.txt
• B. H1 tag
• C. Rel=canonical tag
• D. Meta description tag

Answer: (C)

Indicating the chosen version of a page when you have multiple variants is about telling search engines which URL should be treated as the primary one. The canonical tag does exactly that: it points to a single canonical URL, consolidating signals so that the preferred page is indexed and ranked rather than splitting credit across duplicates. This is especially important when you have duplicate or near-duplicate content across language variants, since it helps avoid confusing search engines and potential ranking penalties. The other options don’t signal a preferred page. Robots.txt controls which pages crawlers access or index; the H1 tag is used for the main page heading and has no bearing on which version is the primary one; the meta description tag influences how a page appears in search results but doesn’t designate a canonical version.
