This article is written for Google Workspace for Education Administrators.
Introduction
The Link insertion feature in Google Editor apps such as Docs, Slides, and Sheets allows students to add external links to their schoolwork. But some students may use this feature to bypass the school’s web filter and access blocked or inappropriate content through the links, making it harder for teachers and IT administrators to control what students can access.
Google Workspace does not provide a built-in setting to restrict the insert HyperLink for students or managed accounts, so administrators need another way to manage it. Blocking websites alone may not solve the problem, as teachers may still need access to sites like YouTube. In the school deployments we support, we have seen that blocking websites alone does not close this gap.
This guide explains why link insertion is diffcult for schools to control, where the common work arounds fall short, and how Safe Doc handles it through the Google Admin Console.
Why Schools want to Disable Hyperlinks in Google Workspace
The problem starts when students use the Insert Link feature to share distracting or inappropriate links in their schoolwork. Other students can then open and share them, creating distractions during class.
K-12 IT administrators are the ones most affected, since they manage Workspace settings but have little control over the inside of a shared file. Teachers notice students getting distracted by those links but usually don't know how students got access to them.
We worked with the same concern that students are using hyperlinks in Google Docs, Sheets, and Slides to access content that the school’s web filter blocks. Some students also add links to restricted videos in Google Slides and use the link preview to view them. At the same time, schools still need websites like YouTube for teaching, so blocking those sites completely isn’t an option.
The issue is not simply that students can access external links. The bigger gap is that schools have limited control over how students use the Insert Link feature inside shared Google Workspace files. Web filters control direct access to websites, where link insertion controls what students can add through the Insert Link feature.These address different parts of the problem.
If this is left unaddressed, teachers lose time dealing with distractions during class, and IT teams end up solving the problem only after it's already happened. Students, meanwhile, keep finding new ways to reach blocked content, which makes school policies harder to enforce over time.

Existing Approaches for Schools to Prevent Link Insertion
Web filtering is a common approach. Schools use firewalls, DNS filters, or other content-filtering tools to block certain websites. But these tools do not stop students from adding links inside Google files and previewing them. That’s why some schools end up looking for a way to block hyperlinks in Google Docs, Slides, and Sheets.
Monitoring tools can show what students are doing, but they only catch problems after they happen. Most existing guides, like Groovy Post and How-To Geek, focus on removing a hyperlink in Google Docs rather than preventing students from adding external links. Removing a link after it has been added does not stop students from inserting new links. Google Workspace Admin Console does not have a native setting to disable only the "Insert Link" feature in Docs, Slides, and Sheets.
These approaches each address part of the problem, but none of them directly target the Insert Link feature itself. Web filtering manages website access, monitoring helps identify activity, and removing hyperlinks deals with links after they have already been added. The core gap remains open.
What Schools Actually Need:
- Manage the restriction centrally through the admin console.
- Apply the restriction across multiple student accounts or OUs.
- Granular control over Insert Link access
- Provide clear configuration and verification steps
Why Insert Link Feature Needs Separate Control in Google Workspace
Links can appear in Google Workspace in several ways, but each feature serves a different purpose.Insert Link allows students to add a URL to content in Google Docs, Slides, or Sheets. Link previews display a preview of the content behind a link, while file sharing controls determine who can access the file.
According to our development team, Google Workspace does not provide a separate setting to control the Insert Link feature. The available settings for link previews and file sharing control those specific features only, but they do not give administrators a setting to restrict students from adding new links in Docs, Slides, or Sheets.
“Insert Link is a specific feature within Google Workspace, so it needs to be controlled separately. Safe Doc provides a targeted way to restrict link insertion without changing the other controls in Docs, Slides, and Sheets.” - Neeraj Nanvani, Development Director of Safe Doc at xFanatical
How xFanatical Safe Doc Restricts Insert Link for Students
xFanatical Safe Doc is a browser extension designed for schools using Google Workspace. It addresses the main link-insertion concern by restricting the Insert Link feature while keeping Google Docs, Slides, Sheets, and Drawings available for regular schoolwork. Administrators can deploy Safe Doc to student accounts and configure the EnableExplore policy for the required Organizational Unit (OU), allowing the restriction to be applied to the student group that needs it.
Once the policy is applied, Safe Doc restricts the Insert Link feature in Google Docs, Slides, and Sheets, helping to prevent students from adding inappropriate, or unsafe external links. This reduces unwanted link sharing in collaborative files, and gives administrators centralized control over link insertion.

Blocking the Insert Link Feature in Google Docs
Once the policy is active, when a student types into the link search box they won’t see any results related to text or link. But Docs remain fully usable for creating or editing the document only the insert link feature is blocked.

Turning Off Link Insertion in Google Slides
The same restriction carries over to Google Slides. Once the policy is active, when a student types into the link search box they won’t see any results. Slides remain fully usable for building out a presentation, only that insert link feature is blocked.

Managing Link Insertion in Google Sheets
In Google Sheets, Safe Doc blocks the same feature at the spreadsheet level. Searching for a link, even a common term or website name, no results will be shown.

Preventing Link Insertion in Google Drawings
When a student tries to insert a link while working on a drawing, no suggestions will appear. The rest of the drawing tools, shapes, text, images, continue working without any change.

To be clear, this policy is not a replacement for the school’s web-filtering solution.It closes one specific gap that is students adding external links through the Insert Link feature. The school’s web filter continues to control access to websites, and the Block Insert Link (EnableExplore) policy works alongside it, rather than replacing it.
