hreflang x-default (2026): when you need it, what it fixes, and the simplest correct setup

Most “hreflang problems” are not hreflang problems.

They are canonicalization and duplication problems that show up as:

• wrong language ranking in the wrong country
• the “wrong” version getting indexed
• Search Console noise (duplicates, alternates, unexpected canonicals)

Start with the base model first:

• Canonical tag vs redirect
• Technical SEO audit checklist

TL;DR

Use hreflang when you have multiple URLs that represent the same page intent in different languages or regions.

Use x-default when you want a neutral fallback for users outside your targeted locales (or when you have a language selector / global landing).

If you have only one language version: you do not need hreflang.

What hreflang actually does

hreflang is not a ranking hack.

It is a routing hint to search engines:

• “This URL is the English version”
• “That URL is the Russian version”
• “If you can’t decide, use this fallback”

Google can still index all versions. You are not “noindexing” anything. You are reducing ambiguity.

What x-default means (in practice)

x-default is the “none of the above” option.

Use it when:

• you have a global homepage that is not tied to a single language
• you have a language selector page
• you run multiple country/language versions and want a stable fallback

If you force everyone into a language based on IP (hard redirects), you can create crawl and indexing problems. x-default is often the cleaner alternative.

Minimal correct setup (copy/paste mental model)

For each page intent, you need a cluster:

• en version
• ru version (or any other)
• optional x-default

Every page in the cluster must:

• reference all other pages (reciprocal)
• be canonical to itself (usually)

Example:

<link rel="alternate" hreflang="en" href="https://casinokrisa.com/start" />
<link rel="alternate" hreflang="ru" href="https://casinokrisa.ru/start" />
<link rel="alternate" hreflang="x-default" href="https://casinokrisa.com/start" />

Notes:

• x-default can point to your global .com version (common), or to a selector page.
• Do not mix: hreflang that points to URL A while canonical points to URL B (unless you know exactly why).

The 6 failure modes that break hreflang

1) No reciprocity

If EN links to RU, but RU does not link back, Google often ignores the cluster.

2) Wrong canonical

If your Russian page canonicalizes to the English page, you are telling Google:

• “RU exists” (hreflang)
• “RU is not primary” (canonical)

Pick one truth. Most of the time: self-canonical on each language version.

3) Wrong status codes

hreflang URLs must be crawlable:

• 200 OK
• not blocked by robots
• no redirect chains

If you need to move URLs, fix the redirects first:

• Page with redirect (GSC)
• Redirect error (GSC)

4) Using the wrong language codes

Use proper codes:

• en or en-US
• ru or ru-RU

Do not invent codes.

5) One page mapped to multiple unrelated intents

If your RU page is not a translation but a different page, do not connect it with hreflang.

hreflang is for “same intent, different locale”.

6) Auto-redirecting Googlebot by geo/IP

If Googlebot always gets redirected away from the page it is trying to crawl, it cannot verify the cluster.

If you must do geo logic, prefer:

• server-side rendering without hard redirects, or
• a selector page with x-default

How to validate (fast, without rituals)

Step 1: check HTML is actually present

Fetch the page source and confirm the <link rel="alternate" hreflang=...> tags exist in the HTML Googlebot sees.

Step 2: check canonicals

Each version should be canonical to itself unless you intentionally consolidate.

If you are seeing “duplicate without user-selected canonical”, fix consolidation first:

• Duplicate without user-selected canonical

Step 3: use GSC URL Inspection (one page per locale)

Inspect EN, then RU:

• is the canonical correct?
• is the page indexed?
• are there unexpected “alternate page” statuses?

If pages are crawled but not indexed, start here:

• Crawled, Not Indexed: what actually moves the needle

FAQ

Do I need x-default if I have only en and ru?

Not always. You need it if you want a stable “fallback” for users outside your main locales or if your UX relies on a selector.

Can hreflang fix ranking?

It fixes wrong-country / wrong-language exposure. It does not create authority. Think: disambiguation, not growth.

Hreflang vs canonical — which wins?

Canonical is a stronger consolidation signal. If they conflict, Google often follows canonical.

So: first decide consolidation, then add hreflang.
