Is the decline in indexed pages on your French site caused by hreflang? Don’t rush to change the configuration. First check the indexing status, then review the language codes, self-referencing tags, and reciprocal annotations. hreflang mainly helps search engines match language versions and is usually not a direct cause of pages being removed from the index.
For website operators, the priority is to identify which French pages have dropped out of the index, why search engines no longer select them, and whether the issue is related to a recent site update. First distinguish changes in indexing, rankings, and search visibility to avoid making configuration changes that fail to improve the situation.
First, confirm: Have indexed pages decreased, or has French search visibility declined?
Start by checking the Page Indexing and Performance reports in Google Search Console. If clicks or impressions in France have fallen while the French pages in the index remain largely stable, first investigate rankings, changes in search demand, and whether search results are displaying pages in other languages.
If the number of indexed pages has actually decreased, filter by the French directory, subdomain, or separate domain, and use the sitemap to confirm the scope of the issue. If you use a URL-prefix property, verify its coverage to avoid mixing data from different language directories.
Do not rely solely on the number of results from a site search operator to judge changes in index coverage; these estimates are not stable. Compare indexing reports from before and after the decline with the sitemap and a list of key URLs. Record changes separately for product, category, and article pages to see which page types are affected.
For your sample, include French pages that have dropped out of the index, pages that remain indexed, and recently added pages, then find their corresponding English versions. Compare indexing status, crawl time, and canonical URL together. This often reveals common issues faster than checking language tags page by page.
Check indexing barriers first: Can the pages still be crawled and indexed?
Use the URL Inspection tool to check affected pages. Note the reported reason for non-indexing, the user-declared canonical URL, and the canonical URL selected by Google. A live test can help confirm the current access status, but passing the test does not mean the page has been added to the index.
Check whether the French URLs return a normal status, redirect incorrectly to the English homepage, or contain a noindex directive. Also investigate server errors, soft error pages, and access verification. These issues can directly affect crawling or indexing and should be addressed first.
Check whether the robots protocol blocks the French directory. For pages blocked from crawling, search engines may be unable to read hreflang tags, canonical tags, or noindex directives. Adding language annotations will not resolve an access barrier; the necessary crawling permissions must be restored first.
If the canonical tags on French product pages all point to English versions, check the site-building template carefully. For complete French pages that you want indexed independently, they should generally declare themselves as the canonical URL. Changing language annotations alone cannot resolve conflicting signals caused by cross-language canonical tags.
Do the language codes and corresponding URLs point to the right pages?
Once the basic indexing conditions are confirmed, check the language codes. Use the language code for French in general, and add a region code for separate versions targeting France or Canada. A region code must not be used on its own. Do not substitute a country name or an underscore for the required format.
<link rel="alternate" hreflang="fr" href="https://example.com/fr/product-a/">
<link rel="alternate" hreflang="en" href="https://example.com/en/product-a/">The example above applies when French and English product pages are corresponding versions of each other. Check each target URL to make sure it is complete, accessible, and points to the final page. Pay particular attention to the domain, path capitalization, and trailing slash, and make sure the tags do not still reference outdated URLs from before a migration.
Do not associate every French product page with the English homepage, and do not treat different product models as corresponding language versions. Language annotations should connect pages with corresponding content. Even if the tag format is correct, a mismatched target page does not represent the actual language relationship.
If French content switches automatically based on the browser language, make sure it has a stable, dedicated URL. When a crawler visits a French URL, it should receive French content directly. Avoid region-based detection or forced redirects that cause it to see only the English page, distorting language signals.
Are self-referencing and reciprocal annotations consistent across all versions?
Each page included in a language-version group should list itself and the other corresponding versions. A common omission is for a French page to declare the English URL but not its own. If the English page does not link back to the French version, the reciprocal relationship is incomplete.
Suppose the same product has English, French for France, and French for Canada versions. All three pages should declare a consistent set of corresponding versions, including themselves. Check by product so you do not assume the entire configuration is correct simply because tags are present in the French template.
Tags can be provided in the page head, HTTP response headers, or a sitemap. There is no need to deploy multiple methods just to increase their effect. If your system already uses multiple sources, check that their URL sets are consistent to prevent an old sitemap and a new template from sending different signals.
A default-language tag can be set as needed to identify the page to serve when no language matches. It is not a prerequisite for French pages to be indexed. Do not treat a missing default tag as the cause of the decline; prioritize fixing missing return links, incorrect URLs, and invalid language codes.
If the configuration is correct, why are French pages still not being indexed?
Language annotations help search engines understand the relationships between versions, but they cannot guarantee that every URL will be indexed. If the report shows that a page was crawled but not indexed, continue by checking whether the main content is complete and useful, and whether the French content is more than just translated menus and headings.
For export product websites, check whether product specifications, use cases, delivery information, and purchasing details have been properly localized into French. If most of the main content is still in English, or many pages contain only repetitive template text, search engines may have difficulty recognizing their independent value.
Also confirm that French navigation, category pages, and body content link to these pages, and that the sitemap lists the final URLs that can be indexed. Language tags alone do not replace normal internal links. Deep pages also need a clear discovery path.
How can you verify whether the fixes worked?
First, save a list of the affected URLs and their indexing status before making changes. Then fix the templates, redirects, or language relationships according to the cause. Before making changes in bulk, test a representative group of pages and confirm that the source code, responses, and sitemap are consistent before applying the fix to other pages.
After updating, check key URLs, request indexing again if needed, and submit the updated sitemap. Then monitor the indexing status and crawl activity of French pages, along with visibility in the target region. These metrics reflect different issues and cannot replace one another.
If you use a multilingual website-building and marketing platform such as Yiyingbao, provide the affected URLs, page templates, and test results to the technical team for investigation, and ask for a record of the updated configuration. Acceptance should be based on specific checks, including page accessibility, correct canonical tags, and complete language relationships.
Conclusion: Troubleshoot based on evidence instead of attributing every drop in index coverage to language tags
When the number of indexed pages on a French site declines, first confirm the scope of the change. Then check access status, indexing directives, and canonical URLs, before reviewing language codes, self-referencing tags, and reciprocal annotations. If these settings are all correct, continue investigating content completeness, internal links, and page value.
To determine whether language annotations are causing a problem, look for evidence of errors on affected pages and check whether search engines reread and adopt the relevant signals after the fix. Keeping a record of changes and consistently comparing the same set of URLs makes it easier to assess the results than changing all settings at once.
