## Summary of SEO for canonical URLs and localized versions of knowledge articles

This feature enhances the search engine optimization (SEO) of knowledge articles in ServiceNow by automatically adding canonical URLs and hreflang tags.
These tags improve searchability and help search engines correctly index both the default and translated versions of knowledge articles.

## Key Features

* **Use SEO script option:** Administrators can enable SEO tags by selecting the *Use SEO script* checkbox on the Knowledge Article View \[kbarticleview\] page record.
* **Canonical URLs:** When enabled, canonical URLs are added to the article view page, ensuring search engines recognize the primary version of each article. The URL format includes the instance name and article number.
* **Hreflang tags:** Tags for translated versions of knowledge articles are included on the article view page, indicating alternate language versions to search engines. A self-referencing hreflang tag is also added for the current article's language.
* **Script includes:** ServiceNow uses specific script includes to implement these SEO tags:
  * **SPSEOHeaderTagsSNC:** Default, read-only implementation for Service Portal pages.
  * **SPSEOHeaderTags:** Extends and allows overriding the default implementation.
  * **SPSEOHeaderTagsArticleViewSNC:** Read-only override specific to the knowledge article view page.
  * **SPSEOHeaderTagsArticleView:** Extends the article view override to allow customization.

## Practical Application for ServiceNow Customers

By enabling the Use SEO script option, administrators can ensure that knowledge articles and their localized versions are properly indexed and ranked by search engines. This improves article discoverability and supports multi-language content management. For further customization, administrators can update the *SPSEOHeaderTagsArticleView* script include to add custom SEO tags tailored to organizational needs.  
Improve the searchability of knowledge articles by adding tags for canonical URLs and
hreflang tags for translated knowledge articles.

You can add the default tags for canonical URLs and hreflang tags by
selecting the Use SEO script check box on the Knowledge Article View
\[kb_article_view\] page record. For more information, see [Enable SEO for canonical URLs and
localized versions of a portal page](https://www.servicenow.com/docs/access?context=seo-sp&version=brazil&pubname=brazil-platform-user-interface&ft:locale=en-US).

When the Use SEO script option is selected:

* The canonical URLs for a knowledge article are added to the knowledge article view page.Example canonical URL: https://\<instance name\>.servicenow-com/csp?id=kb_article_view\&sysparm_article=\<article number\>

* The hreflang tags for the translated versions of a knowledge article are added to the knowledge article view page.

  Example URL with an
  hreflang tag: \<link rel="alternate" href="https://\<instance name\>.servicenow-com/csp/fr?id=kb_article_view\&sysparm_article=\<article number\>" hreflang="fr"/\>  
  Note:  
  A self-referencing hreflang URL is also added for the language of current knowledge article.

  For example, an English
  knowledge article is viewed by visiting a URL with the following
  format:

  https://\<instance name\>.servicenow-com/csp/?id=kb_article_view\&sys_kb_id=\<sys_id\>

  In
  addition to the hreflang tags added for translations, the English
  language self-referencing hreflang tag is
  added:

  \<link rel="alternate" href="https://\<instance name\>.servicenow-com/csp/?id=kb_article_view\&sys_kb_id=\<sys_id\>" hreflang="en"/\>
