Question 1

What happens if I miss the self-referencing hreflang tag?

Accepted Answer

If you omit the self-referencing tag, the entire hreflang cluster for that specific page will fail validation. The bidirectional rule requires that every page listed in the cluster must contain the exact same set of tags, including a tag pointing to itself. Without it, search engines view the network as incomplete and will ignore the directives, leading to potential duplicate content issues and incorrect regional ranking.

Question 2

Can I use hreflang to target specific cities or states?

Accepted Answer

No, hreflang relies exclusively on ISO 3166-1 alpha-2 codes, which only recognize sovereign nations and specific independent territories. You cannot use hreflang to target "New York" versus "California," nor can you target "London" versus "Manchester." If you need to target sub-national regions, you must rely on traditional local SEO tactics, such as localized on-page content, Google Business Profiles, and local backlinks.

Question 3

Does Bing support hreflang tags?

Accepted Answer

No, Bing officially does not support the hreflang attribute. Bing's crawler relies on the content-language meta tag, the lang attribute within the <html> tag, top-level domains (ccTLDs), and the physical server location to determine the language and region of a page. To optimize for both Google and Bing, webmasters must implement hreflang alongside these traditional HTML language declarations.

Question 4

Do I need an hreflang tag for every language in the world?

Accepted Answer

You only need to generate hreflang tags for the specific languages and regions that you actively support with localized content. If you only have an English page and a Spanish page, you only need two tags (plus an optional x-default). You do not need to create tags for languages you do not have translated content for; the x-default tag will catch all other global users and direct them to your primary fallback page.

Question 5

Should I use XML sitemaps or HTML head tags for hreflang?

Accepted Answer

For small websites with fewer than 5 languages and under 1,000 total pages, HTML head tags are perfectly acceptable and easier to implement. However, for enterprise e-commerce sites, large publishers, or any site exceeding 10,000 pages with complex regional matrices, XML sitemaps are the definitive best practice. XML sitemaps keep the HTML code clean, improve page load speeds, and centralize the management of complex bidirectional links into a single database output.
