automatic assignment of rel="nofollow" and rel=""noopener noreferrer nofollow"

[rachana_patel]

when I am editing a kb article 

• all > knowledge >. select any KB article > edit 

• inside article body section 

  toggle it to HTML view 

  and paste this link 

  <p><a href="https://sahilife.service-now.com">https://sahilife.service-now.com</a></p>

  update article .

  open article like any user would view it.

• right click and inspect it.
• hover on the above link inside inspect element
• you see rel="nofollow" is added on that link automicatally.

why does this happen? how come this automatically appends on to our html code? what is the funcationality behind it.

@rachana_patel,

The nofollow value for the rel link attribute is used to signal to search engines that they shouldn’t follow these links and therefore shouldn’t pass any link authority to the link target. Google in particular may, however, choose to ignore this and follow the link and/or pass on link authority.

rel="nofollow" is automatically added by ServiceNow.

To my understanding this attribute nofollow value for the rel link attribute is used to signal to search engines that they shouldn’t follow these links and therefore shouldn’t pass any link authority to the link target. Google in particular may, however, choose to ignore this and follow the link and/or pass on link authority.

I tried the below

1. Added the HREF code from your original post and rel="nofollow" was automatically added.

2. I gave the below HTML code in the KB Article and even in this case rel="nofollow" was automatically added.
<p><a href="/incident_list.do">Incident List</a></p>

Even though the link only redirects to the current ServiceNow incidents list page the attribute is automatically added.

@rachana_patel 

rel="nofollow" may have been added by HTML Sanitizer. There's a system property that enforces sanitization on translated_html fields.

You can refer to this page to know more - https://docs.servicenow.com/en-US/bundle/utah-platform-security/page/administer/security/reference/c...
