Before troubleshooting, think about\nwhether the Google-selected canonical makes more sense than your preferred canonical URL for\nyour users coming from Google Search.\n\n\nThere are various reasons why the selected canonical URL differs from the canonical URL you'd\nprefer to see in Search. The most common issues are:\n\n| Common canonicalization issues ||\n|-------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Language variants without localized annotations ----------------------------------------------- | If you have multiple websites that serve substantially the same content localized to different users around the world, be sure to [follow our guidelines for localized sites](/search/docs/specialty/international). For example, if you have different sites for your English-speaking users in the United States, United Kingdom, and Australia respectively, but the content is the same, adding `hreflang` annotations to your pages can help the right pages surface for users in different regions. |\n| Incorrect canonical elements ---------------------------- | Some content management systems (CMS) or CMS plugins can make incorrect use of canonicalization techniques to point to undesired URLs. Check your HTML with your browser's developer tools to see if so. If your site is indicating an unexpected canonical URL preference, perhaps through incorrect use of `rel=\"canonical\"` or a `3xx` redirect, contact your CMS provider and report this error to them. |\n| Misconfigured servers --------------------- | Some hosting misconfigurations may cause unexpected cross-domain URL selection. For example: - A server may be misconfigured to return content from `example.com` in response to a request for a URL on `other.example` - Two unrelated web servers may return identical [`soft 404` pages](/search/docs/crawling-indexing/http-network-errors#soft-404-errors) that Google fails to identify as error pages. If you notice this is the case, get in touch with your hosting provider. |\n| Malicious hacking ----------------- | Some attacks on websites introduce code that returns an HTTP [`3xx` redirect](/search/docs/crawling-indexing/301-redirects) or inserts a cross-domain `rel=\"canonical\"` `link` annotation into the HTML `\u003chead\u003e` or HTTP header, usually pointing to a URL hosting malicious or spammy content. In these cases, our algorithms may choose the malicious or spammy URL instead of the URL on the [compromised website](https://web.dev/articles/hacked). |\n| Syndicated content ------------------ | The canonical link element is not recommended for those who want to avoid duplication by syndication partners, because the pages are often very different. The most effective solution is for partners to block indexing of your content. For more, see [Avoid article duplication in Google News](https://support.google.com/news/publisher-center/answer/9606800), which also has advice about blocking syndicated content from Google Search. |\n| A copycat website ----------------- | In rare situations, our algorithm may select a URL from an external site that is hosting your content without your permission. If you believe that another site is duplicating your content in violation of copyright law, you may contact the site's host to request removal. In addition, you can request that Google remove the infringing page from our search results by [filing a request under the Digital Millennium Copyright Act](https://support.google.com/legal/answer/1120734). |\n\n\nKeep in mind that if a canonical URL is in a Search Console property that you don't own, you won't\nbe able to see any of the traffic for your duplicate page."]]
