Compare main content and purpose
List affected URLs, their main content, status and actual usefulness. Sharing a menu does not necessarily make pages duplicates. A translated main body is not treated like a same-language copy.
| Situation | Useful question | Action to consider |
|---|---|---|
| Tracking parameters | Does the main content change? | Canonical preference and consistent links. |
| Retired old URL | Is there a true equivalent? | A targeted permanent redirect. |
| Useful filters or variants | Do they serve a distinct need? | Preserve the use and decide case by case. |
| Full translation | Is the main body translated? | Localized URL and language annotations. |
Match the action to the cause
- Group genuinely equivalent variants before changing signals. Do not automatically redirect pages serving different needs.
- If an old URL no longer serves a purpose, consider a permanent redirect to its equivalent. If variants must remain accessible, define a consistent canonical preference.
- Align internal links, sitemap and annotations, then check Google’s selected URLs. Do not block crawling while expecting an inaccessible annotation to be read.
Preserve each page’s distinct value
A similar page can remain useful if it provides distinct, verifiable information. Avoid word substitutions made only to disguise copying. Separate technical mistakes, authorized republication, content rights and production intended to manipulate search.

Decide which similar page serves which need
Two similar URLs are not automatically a technical defect to hide. Distinguish genuinely different intents, then consolidate duplicates without losing useful links, canonical signals or journeys.
- Compare target question, unique information and next action on each page.
- Choose keep, merge or redirect from user need and content value.
- Check canonical, redirects, sitemap and internal links after release.

Handle duplicate URLs according to their actual role
Fictional example: these inputs describe no customer or observed result.
Two URLs show one guide: one is retained for a campaign and the other is the editorial reference.
- Check content, internal links, canonical and the reason for retaining each URL. Distinguish distribution duplicates from genuinely different language editions.
- Align signals with the chosen reference. Do not automatically describe every duplicate as a penalty or merge different intents without review.
