Ensuring your website is properly indexed by search engines is crucial for online visibility and organic traffic. However, technical issues related to canonical tags can inadvertently prevent your pages from appearing in search results or cause duplicate content problems. Among these issues, canonical tag errors are particularly common and can significantly impact how Bing indexes your site. Understanding and correcting these errors is essential for maintaining optimal search performance and avoiding unnecessary deindexing or ranking drops.
Canonical Tag Errors That Affect Bing Indexing
Canonical tags serve as a way to inform search engines about the preferred version of a webpage when duplicate or similar content exists. Proper implementation ensures that Bing and other search engines consolidate ranking signals and avoid indexing multiple versions of the same content. However, mistakes in canonical tags can lead to indexing issues, duplicate content problems, or even deindexing. Below, we explore the most common canonical tag errors that can negatively influence Bing's indexing process.
1. Incorrect or Broken Canonical URLs
-
Absolute vs. Relative URLs: Using relative URLs in canonical tags can confuse search engines. For example,
<link rel="canonical" href="/page/">may not be interpreted correctly if the base URL isn't properly set. - Typographical Errors: Misspelled URLs, incorrect domain names, or missing slashes can cause Bing to ignore the canonical tag altogether.
- Non-Existing Pages: Pointing canonical tags to pages that return 404 errors or redirect improperly can prevent Bing from recognizing the canonical version.
Example: Suppose a canonical tag points to https://www.example.com/page, but the live page is https://www.example.com/page/. Bing might treat these as separate URLs, leading to duplicate content issues.
2. Multiple Canonical Tags on a Single Page
Having more than one canonical tag on a webpage creates ambiguity for Bing about which URL is the preferred version. Search engines may then choose the first canonical tag they encounter or ignore both, resulting in indexing confusion.
To avoid this, ensure each page contains only one canonical tag that explicitly specifies the preferred URL.
3. Canonical Tags Pointing to Irrelevant or Incorrect Pages
- Pointing canonical tags to unrelated pages or outdated URLs can cause Bing to index the wrong content.
- This often happens during site migrations or URL restructuring when canonical tags are not updated accordingly.
For example, if a product page's canonical tag points to the homepage, Bing may index the homepage instead of the specific product page, diluting SEO efforts.
4. Canonical Tags Missing or Not Implemented
Failing to implement canonical tags on pages with duplicate or similar content can result in Bing indexing multiple versions separately, leading to duplicate content issues and diluted ranking signals.
Proper canonicalization helps Bing understand which version to prioritize, consolidating link equity and improving ranking potential.
5. Using Canonical Tags on Non-Canonical Pages
- Applying canonical tags to pages that shouldn't be canonical, such as category or archive pages, can mislead Bing into ignoring valuable content.
- Ensure canonical tags are used appropriately on duplicate or similar content pages, not universally.
6. Canonical Tag Conflicts with Robots.txt or Noindex Directives
If a page has a noindex directive in robots.txt or meta tags but also contains a canonical tag pointing elsewhere, Bing may struggle to understand whether to index or exclude the page. This inconsistency can cause indexing problems or unintentional deindexing.
7. Canonical Tag Implementation on Dynamic or E-commerce Sites
- Dynamic URLs with session IDs or tracking parameters often require canonical tags to prevent duplicate content.
- Incorrect implementation, such as canonicalizing to URLs with parameters, can confuse Bing and hinder proper indexing.

Conclusion
Canonical tag errors are a common but fixable cause of indexing issues on Bing. Incorrect URLs, multiple tags, pointing to irrelevant pages, or missing implementation can all lead to duplicate content problems, reduced visibility, or even deindexing. Regular audits, correct implementation, and staying updated with best practices are key to ensuring Bing correctly understands your website’s structure. If your site has been deindexed or isn't performing as expected, addressing canonical tag issues should be a priority.
Remember, proper canonicalization not only improves your chances of being indexed but also consolidates your SEO efforts, boosting your rankings and visibility in search results. Stay vigilant, optimize your tags, and consult professionals when needed to maintain a healthy, search-engine-friendly website.
