Free Guide to Enabling YouTube Video Comments

Understanding YouTube Comment Settings and Basic Features

YouTube offers creators several ways to manage comments on their videos. Comments are one of the most important features on the platform, with over 500 hours of video content uploaded to YouTube every minute. Understanding how to enable comments is a fundamental step for anyone who wants to build community engagement on their channel.

When you upload a video to YouTube, comments are typically enabled by default. This means viewers can leave feedback, ask questions, and interact with your content immediately after the video goes live. However, there are situations where comments may be disabled—either automatically by YouTube's systems or intentionally by the creator. Knowing how to re-enable them puts you in control of your video's discussion space.

YouTube distinguishes between different comment settings. You can allow all comments, hold comments for review before they appear publicly, or disable comments entirely. Each setting serves different purposes depending on your channel's goals and the content you create. For example, YouTube reported in 2023 that channels with active comment sections see 30% higher viewer retention rates compared to channels with disabled comments.

The comment feature works across all YouTube platforms—the main website, YouTube Mobile, YouTube TV, and YouTube Studio. This means once you enable comments on a video, they'll be visible and functional regardless of how viewers access the content. Comments can include text, links, and mentions of other users, making them a rich communication tool.

Practical takeaway: Check each video's comment settings individually, as enabling comments on one video doesn't automatically enable them on all your videos. You'll need to adjust settings for each piece of content based on your moderation preferences.

Step-by-Step Process for Enabling Comments on Existing Videos

To enable comments on videos you've already uploaded, you'll start by logging into YouTube Studio. This is YouTube's creator management platform where you control all aspects of your channel and videos. Go to YouTube.com, click your profile icon in the top right corner, and select "Create a video" or "YouTube Studio" from the dropdown menu. Once in YouTube Studio, click "Content" in the left menu to see your video library.

Find the video where you want to enable comments. You can search by title or scroll through your uploads. Click on the video thumbnail to open its details page. On this page, you'll see several tabs including "Details," "Advanced settings," and "Comments." Click on the "Comments" tab to access comment-specific settings for that video.

In the Comments section, you'll see a toggle button next to "Allow comments." If this toggle is currently off (grayed out), click it to turn it on. The toggle will turn blue when comments are enabled. You may also see options to choose your comment moderation level. YouTube offers three moderation settings: "Approve all comments and responses" (where you review every comment before it appears), "Likely spam and comments with links will be held for review" (the default setting that filters obvious spam), or "Hold potentially inappropriate comments for review" (a more permissive setting).

After you've selected your preferred settings, YouTube automatically saves your changes. You don't need to click a separate "Save" button. The changes take effect immediately, and viewers will be able to see and post comments on your video within seconds. If you've chosen to review comments before they appear, you'll receive notifications when new comments are awaiting your approval.

Practical takeaway: Start with the default moderation setting ("Likely spam and comments with links will be held for review") which provides a good balance between community engagement and spam prevention without requiring you to manually review every single comment.

Managing Comment Moderation and Filtering Options

Once comments are enabled, YouTube provides tools to manage the quality and nature of discussions on your videos. The platform uses machine learning algorithms to identify potential spam, harassment, and inappropriate content. According to YouTube's transparency reports, automated systems remove approximately 99.1% of spam and abuse before anyone reports it, though creators also have manual control options.

You can create a list of blocked words, phrases, or channels. This is especially useful if you manage a channel aimed at younger audiences or if you want to prevent discussion of specific topics. To set up these filters, go to YouTube Studio, click "Settings," then "Community," and then "Block words." Enter words or phrases you want filtered, and YouTube will hold comments containing those terms for review. You can separate multiple items with commas. This feature is case-insensitive, so "BadWord," "badword," and "BADWORD" will all be caught by the same filter.

You also have the option to automatically hold comments from new users for review. This setting requires you to manually approve comments from viewers who haven't previously had approved comments on your channel. While this creates more work for you, it can significantly reduce harassment and spam for popular channels. Channels with 10,000 or more subscribers might particularly benefit from this approach, as they often attract more spam-related activity.

Another useful feature is comment pinning. When you pin a comment, it appears at the top of the comments section, even if it's not the newest or most liked comment. Many creators pin comments that answer frequently asked questions, provide important clarifications, or highlight interesting viewer responses. You can pin up to five comments per video.

Practical takeaway: Use YouTube's built-in filtering tools rather than disabling comments entirely. Research shows that channels with active, well-moderated comment sections build stronger communities and see better audience retention than channels where comments are turned off.

Enabling Comments on New Videos and Default Settings

When you upload a brand new video to YouTube, comments are enabled by default unless you've changed your channel-wide default settings. However, understanding how to confirm these settings ensures you don't accidentally upload a video with comments disabled. This is particularly important if you've previously disabled comments on certain videos and want to ensure new uploads have different settings.

When uploading a new video, you'll reach the "Details" page where you can add your title, description, and thumbnail. Below this information, there's a section labeled "Visibility" with options for Public, Unlisted, or Private. Below that, you'll often see a "Comments" section. You can set your comment moderation preference right at upload time, choosing between your three moderation options before the video is published.

To set a channel-wide default for comment moderation, go to YouTube Studio, click "Settings," then "Community," and look for "Default comment setting for new uploads." This setting applies to all videos you upload from that point forward, though you can still change individual video settings after upload. Most creators choose the default spam-filtering option, which balances openness with protection.

There are specific situations where you might want to disable comments on new uploads. Educational content creators, channels posting sensitive topics, or channels experiencing harassment sometimes disable comments and instead direct conversation to other platforms like Discord or Reddit. YouTube's data shows that approximately 8% of creators regularly disable comments on some or all of their content, though this number is declining as communities become more sophisticated at moderation.

Practical takeaway: Set your preferred default comment setting in your channel settings, then verify the setting on each important video before publishing to make sure it matches your intentions for that specific piece of content.

Responding to Comments and Building Community Engagement

Enabling comments is only the first step—responding to them creates real community engagement. Channels that respond to a significant portion of comments see 20-30% higher engagement rates in subsequent videos. YouTube provides several tools to make comment management easier and more organized.

When you respond to a comment, you have options for how that response appears. A regular reply appears as a nested comment directly under the original comment. You can also use the @mention feature to tag other users in your response—typing "@username" alerts that user to your response and makes it easier for them to see it in their notifications. If you want to highlight a comment as important, you can "heart" it, which places a small heart icon next to the comment and makes it visually stand out to other viewers.

YouTube Studio provides a dedicated comments interface where you can review all comments across your channel, filter by video, sort by date or popularity, and manage moderation in bulk. This is more efficient than reviewing comments on individual video pages, especially for channels with hundreds of videos and thousands of comments. You can approve, delete, or report comments directly from this interface without visiting each video.

Building community norms through your own responses shapes how people interact on your channel. Creators who respond thoughtfully to genuine questions, acknowledge helpful comments from viewers
