Would either page satisfy the same reader
Imagine a reader arriving with one specific question. If switching languages sends that reader to a different answer, the destination is a related article rather than a substitute for the page they opened.
Google describes the purpose of hreflang in terms of content variations:
these pages are localized variations of the same content.
Google: Tell Google about localized versions of your page
Use that scope as the starting point, then compare the proposed pair with a short editorial record:
| Comparison | Evidence to record |
|---|---|
| Reader task | The question each page answers and the decision the reader can make afterward |
| Main answer | Where each page gives the answer, including its essential steps or criteria |
| Essential information | The facts and supporting material needed to complete that task |
| Scope | Conditions or exclusions that affect whether the other page is a usable alternative |
Identical headings and paragraph order are unnecessary for this check. Different examples can still support the same answer. Matching titles, however, cannot compensate for a missing central explanation. Read the main content of both pages before approving a pair.
Three possible outcomes for a proposed pair
The following categories are editorial criteria for deciding what to connect. The examples are hypothetical. They are not categories that Google says it automatically assigns to pages.
Genuine language versions
A Chinese installation guide and an English installation guide for the same hypothetical device both explain how to connect it and complete its initial setup. Both retain the main steps and limitations, although the wording and examples differ. They are candidates for an alternate-language relationship because either page can complete the same reader task.
Partially localized versions
One guide retains the same central answer but replaces an example or supporting reference for its audience. It may still be a valid alternative. Check what the adaptation changes: if the other page loses an essential step or answers only one subsection, hold the pairing until it offers an equivalent answer.
Google's examples include pages whose main content stays in one language while navigation or footers are translated, and similar content with small regional variations in a single language. These examples do not by themselves establish whether a guide with replaced examples or references is an equivalent alternative. For that pair, the editorial question remains whether the main answer and essential information survive the adaptation.
Independent topics
A Chinese returns-policy FAQ and an English installation guide for the same hypothetical device cover different tasks. One explains return conditions; the other explains setup. Keep them separate. Pairing them would describe a content relationship that the articles do not offer.
Check annotations only after the pair qualifies
For a valid set of alternatives, Google's guidelines require each language version to identify itself and the other versions. They also require complete URLs and reciprocal references; Google says tags between two pages will be ignored if the pages do not point to each other.
| Check | What should be present |
|---|---|
| Qualified destinations | Every listed page passed the content comparison |
| Self-reference | The Chinese page lists its own URL; the English page lists its own URL |
| Other versions | Each page lists the valid alternatives in the set |
| Return relationship | Every proposed pair points in both directions |
| Complete addresses | Each destination includes its full URL, including the http:// or https:// scheme |
| Language codes | Each annotation uses a supported code for its intended version |
For a hypothetical two-page set, use this sequence:
- Write down both complete URLs and the corresponding language codes.
- Check the delivered Chinese-page annotations for both its own URL and the English destination.
- Open the English page and confirm its self-reference and return reference to the Chinese page.
Inspect what the pages actually deliver. A publishing spreadsheet that merely says the pair exists cannot confirm the annotations are present.
Give independent articles accurate reading links
When there is no equivalent article, an ordinary link can still help a reader explore a related subject. Label it with the destination's actual topic. Avoid a generic “English version” label if that page answers another question.
Keep related reading separate from the list of language alternatives. For example, choosing a GEO team across languages and markets and resolving a Chinese–English meaning dispute address different editorial decisions. Neither becomes this article's alternate merely because it concerns bilingual content. For the handoff itself, see Chinese review and English copy revisions.
Revisit the relationship when an article's central answer changes. If the other page no longer serves the same task, reassess the pairing before carrying its annotations forward. An unpaired article is a valid editorial outcome. The hreflang annotation describes language alternatives; it does not promise indexing, ranking or citation in an AI answer.
