What does Google say about SEO? /
International SEO encompasses critical practices for optimizing website visibility across multilingual audiences and geographic markets. This category compiles Google's official statements regarding the technical implementation of international search optimization, including the proper use of hreflang tags to signal language and regional variants, domain architecture choices (ccTLD, subdomains, subdirectories), and geographic targeting strategies through Search Console. Google's guidance on these topics is crucial for avoiding critical mistakes such as duplicate content issues between language versions, indexation problems with alternate pages, or confusion in geographic targeting signals. SEO professionals must understand official recommendations concerning content translation versus localization, management of geolocation signals (IP address, local links, hosting), and correct implementation of hreflang annotations through HTML markup, XML sitemaps, or HTTP headers. These authoritative statements enable practitioners to develop international strategies aligned with Google's expectations and maximize organic presence across multiple markets simultaneously. Understanding Google's evolving position on international SEO helps prevent costly errors and ensures efficient crawl budget allocation across global site versions.

★★★ Merging two websites: Why doesn’t Google treat this like a standard migration?
Merging two websites into one is not a standard site migration. It involves creating a new site that combines two existing versions, which requires Google to re-crawl numerous pages. The outcome and p...

★★★ How Does Google Actually Determine the Canonical URL of Your Pages?
John Mueller provided on Twitter a list of criteria that Google takes into account to define what the canonical URL of a page is (and therefore its "canonicalization"): redirects, internal links, exte...

★★★ Should You Index Automatically Translated Content Without Human Review?
Gary Illyes indicated on Twitter that the official recommendation was not to index content that would be translated automatically (with software/algorithm like GPT-3) without subsequent human review. ...

★★ Should you really implement hreflang on every page of a multilingual website?
It is perfectly acceptable to use hreflang only on certain pages (e.g., home, about) and not to use it on other pages of the same site (e.g., localized but untranslated blogs). Hreflang applies on a p...

★★ Why does Google make it impossible to use Search Console Insights without Analytics?
Google Search Console Insights combines data from Google Analytics and Search Console to provide a simplified view. Both data sources are required for the tool to function since it integrates informat...

★★★ Is the rel=canonical really mandatory on all AMP pages, even standalone ones?
For paired AMPs (classic page + AMP), the canonical is required. For standalone AMPs (no classic version), the page must canonicalize to itself. This rule is independent of hreflang and translations....
John Mueller Aug 21, 2020
★★★ Is Google really merging your multilingual pages into a single canonical URL?
When a site has identical content pages targeting different countries (e.g., French Canada vs. France), Google may group (fold) them into a single canonical version in the index. In Search Console, on...
John Mueller Aug 21, 2020
★★ Should you really implement hreflang across an entire multilingual site?
Hreflang can be used selectively: only on certain pages (homepage, key pages) without needing to implement it site-wide. It’s a page-level annotation, not a global requirement....
John Mueller Aug 21, 2020
★★★ Why does Google only index one language when your site switches through JavaScript?
If the site's language is managed solely by JavaScript/cookies (same URL for all languages), Google can only index one language version because Googlebot does not follow language switchers or use cook...

★★★ Is cross-domain duplicate content really harmless for your SEO?
Having the same content in the same language across multiple domains (e.g., English content on .com and .pl) is not penalized. Google simply chooses a canonical URL. If the content differs slightly (l...

★★ Why does Google sometimes ignore your canonical tag to serve a different URL?
Even if a URL is set as canonical, Google may display a different regional variant based on the user's location. For example, between a German version (.de) and an Austrian version (.at) with the same...
Martin Splitt Aug 13, 2020
★★ Is Google really tolerant of hreflang errors that mismatch language and content?
If a Japanese page (e.g., /jp) declares in its hreflang x-default or hreflang that it is in English while the content is in Japanese, this creates an inconsistency. Although this needs to be corrected...
John Mueller Aug 11, 2020
★★★ Does Googlebot really ignore your multilingual site's accept-language header?
Googlebot almost never crawls with a defined accept-language header, or sometimes uses 'en' (English). If a site serves different content based on the user's accept-language header, Google will only s...
John Mueller Aug 11, 2020
★★★ Does Googlebot really send an accept-language header during crawling?
Googlebot almost never crawls with an accept-language header, or uses English, or sends no language at all. If a site serves content based on this header, Google will only see the English version (or ...
John Mueller Aug 11, 2020
★★ Why does Google choose a canonical URL in the wrong language for your multilingual content?
If Google selects a canonical page in a different language (e.g., Portuguese chosen instead of Japanese), when the pages are indeed in distinct languages, the issue likely stems from poor server confi...
John Mueller Aug 11, 2020
★★★ Can Google really tell the difference between your multilingual pages, or is it at risk of mistakenly canonicalizing them?
Google typically does not confuse pages in different languages (Japanese vs Portuguese, for example) and does not consider them duplicates to be canonicalized together. Translated content is considere...
John Mueller Aug 11, 2020
★★★ Should you really keep each hreflang page self-canonical?
Pages linked by hreflang must be self-canonical (each version points to itself as canonical). If all versions canonicalize to a single page, Google will follow this directive, index only this unique p...
John Mueller Aug 04, 2020
★★★ How does Google really differentiate between two sites in the same language but targeting different countries?
For Google to treat pages separately by country (same language), clear local signals are needed: different currencies, local phone numbers, local physical addresses. These elements allow algorithms to...
John Mueller Aug 04, 2020
★★ Is it really necessary to use hreflang for a multilingual website?
For versions in truly different languages (English, Spanish, German), hreflang is often not required because users search in their language and Google naturally displays the correct version. Hreflang ...
John Mueller Aug 04, 2020
★★ Why is Search Console showing the wrong URL for Hreflang and Canonical?
When Google groups similar hreflang pages by selecting a unique canonical, it still displays the correct localized version in search results (e.g., Swiss URL for Switzerland). Search Console shows dat...
