Which tag indicates the preferred version of a page to search engines?

• A. Canonical tag
• B. Meta robots tag
• C. Hreflang tag
• D. Title tag

Answer: (A)

The question is about how to tell search engines which page is the preferred version when there are duplicate or similar pages. The canonical tag is a rel="canonical" link placed in the page’s head that designates the canonical URL—the version you want to be considered the main one for ranking signals. By pointing all duplicate content to this canonical URL, you consolidate signals like links and user signals to a single page and avoid splitting those signals across multiple URLs. This helps prevent duplicate content issues and can improve how the chosen page ranks. Other tags don’t serve this purpose. The meta robots tag controls whether a page should be indexed or followed, but it doesn’t specify a preferred version. The hreflang tag indicates language or regional variants for international audiences, not which page is the canonical version. The title tag is the page’s displayed title in search results and on the site; it helps with click-throughs and relevance but does not declare a preferred URL. So using the canonical tag to declare the preferred version is the proper method for guiding search engines to treat a single URL as the main page.
