This article is for IT support at schools using Connect for Chrome on student devices.
You can use Content Modification to block potentially harmful or distracting features like comments or recommended videos from resources like YouTube, both in the classroom and outside of school hours. Unlike traditional content filtering, which blocks a set of websites or keywords, Content Modification provides a more dynamic approach to policy creation, allowing you to customize what elements of a webpage students can see.
Note
School Manager Content Filtering block policies and Classwize block rules override Content Modifications. For example, if a Content Filtering policy blocks YouTube access, School Manager won’t apply your Content Modification policy to YouTube content.
Important
This feature is intended for use with the Linewize Connect for Chrome extension only. If your school has a School Manager physical appliance, On School Manager Network Filtering must be enabled for Connect for Chrome to perform Content Modification.
School Manager currently allows you to create six types of Content Modification Policies.
| Type | Description |
| Block Embedded Games |
Remove embedded iFrames from websites categorized under the Blogging category. Students can access a games website in this category but no game will load on the page, leaving a blank area where the game would be. |
| Hide Reddit Login |
Hide Reddit from showing “Log In”, thereby blocking Log In / Sign Up functionality. Stop students going to https://reddit.com/login , results in a blank page. |
|
Remove YouTube Comments |
Stop YouTube from showing comments. Stop students from being able to comment on YouTube videos. |
| Remove YouTube Description | Stop YouTube from showing video descriptions under videos. |
| Remove YouTube Recommended Videos | Stop YouTube from showing recommended videos on its homepage and in the ‘Up next’ section.
Note This policy type does not impact YouTube's auto-play feature or the display of video ads. |
| Remove YouTube Search | Stop YouTube from showing the search bar. |
Prerequisites
To use Content Modification, you will need to ensure Connect for Chrome is enabled on students’ devices.
Create a Content Modification Policy
- In School Manager, select Filtering > Content Modification.
- Select Create Policy or edit an existing policy.
- Name your policy.
- Set the Type of your policy to one of the available content modifications:
- Block Embedded Games
- Hide Reddit Login
- Remove YouTube Comments
- Remove YouTube Description
- Remove YouTube Recommended Videos
- Remove YouTube Search
- Use Criteria to set who the policy will apply to.
Warning
Selecting multiple criteria in a Policy requires the first criteria AND all other criteria to be true before the policy applies. For example, If you select a Group and Network criteria for a policy, the policy would only apply to users who are both in the selected group and on the IP subnet.
- Select Save Policy.

Who can see the Content Modification item in the left window? One of my admins does not. What rights do you need to see / configure this?
Also with Classwise there is the Locked rule and the unlocked rule. I suspect this is locked and cannot be overridden. Correct?
Also you might want to explain what some rules do more. It does seem to stop autoplay of the next video which is a good thing. Does this do anything else? Commercials?
Nice job on giving us more tools.
Thanks for your feedback, Mike! We're glad it's a useful tool for you. We'll also get right on updating the article with answers to your questions and expanding on what the rules do. But in the mean time:
Users with a role that gives them access to filtering (Owner/Global Admin, Filtering / Reporting Administrator, Filtering Administrator and Cloud Only Filter Administrator) should be able to see and use Content Modifications. However, they will need to enable it in the Feature Lab first. If they've got the right role and have enabled Content Modifications the Feature Lab but still don't have access, please contact our support team so they can find out what's going on.
Yes, Locked policies (rules) will override other rules, including any Classwize rule.
What does the "Block Embedded Games" entry actually do in the Content Modification rule? I think we need more details on what that actually does to make an informed decision. Does this go after the games on Google Sites or? Thanks!
Hi Ed Leader, thanks for your comment! An article update is coming soon, but for now, the Block Embedded Games content modification rule removes embedded iFrames from all websites categorized under the Blogging signature, which includes Google Sites. Students can access the site, but no games will load on the page, leaving a blank area where the game would be.
