TikTok gives creators four levels of comment control: who can comment, which keywords are blocked, which comments need approval, and whether comments are turned off entirely. Most users only know about the on/off switch — the granular controls are buried two or three menus deep.
This guide walks through every option, then explains why brands and agencies usually want a different strategy entirely: keep comments open, but get full visibility into them through exports and sentiment monitoring.
Method 1: Restrict who can comment (account-wide)
This is the broadest setting. It applies to every video on your account, not individual posts.
- Open TikTok and tap Profile (bottom right)
- Tap the menu icon (three lines, top right)
- Go to Settings and privacy → Privacy
- Tap Comments
- Under "Who can comment on your videos", choose:
- Everyone — default; any TikTok user can comment
- Friends — only mutual follows can comment
- No one — disables comments entirely on the account
The setting takes effect immediately on all existing and future videos.
Method 2: Disable comments on a single video
If your account is set to "Everyone" but you want to disable comments on one specific post:
- Open the video on your profile
- Tap the three dots on the right side
- Tap Privacy settings
- Toggle off Allow comments
You can also set this at upload time: when posting a new video, expand "More options" before tapping Post and toggle off "Allow comments".
Method 3: Filter comments by keyword
The most useful tool that almost no one uses. Keyword filters hide comments containing specific words before they're visible to anyone (including you, unless you check the Filtered tab).
- Profile → menu → Settings and privacy → Privacy
- Tap Comments
- Toggle on Filter keywords
- Tap Keywords and add up to 200 words/phrases (comma-separated)
Some practical keyword lists to start with:
- Scam/spam filter: dm, telegram, whatsapp, link in bio, my profile, free, giveaway scam
- Competitor mentions (for brands): names of your top 3 competitors
- Profanity: TikTok's own "Filter spam and offensive comments" toggle covers most, but you can add brand-specific terms
- Off-topic hashtags: any tag you don't want associated with your content
Method 4: Approve comments before they're visible
Comment approval mode hides all incoming comments until you manually approve each one. Best for high-stakes posts (product launches, sensitive announcements) where one viral troll could derail the conversation.
- Profile → menu → Settings and privacy → Privacy
- Tap Comments
- Toggle on Filter all comments
Pending comments appear in the Filtered tab of each video's comment panel. You'll need to review and approve each one for it to appear publicly. This is high-overhead — most creators leave it off and use keyword filtering instead.
Method 5: Filter spam and offensive comments (automatic)
TikTok's built-in spam/offensive comment filter uses ML to hide low-quality comments before they reach your video. It's on by default for most accounts, but worth verifying:
- Profile → menu → Settings and privacy → Privacy
- Tap Comments
- Confirm Filter spam and offensive comments is on
This is the lowest-effort setting and the one every account should have enabled.
Method 6: Delete or report individual comments
For comments that slipped through filters:
- Long-press the comment
- Choose Delete (removes from the thread) or Report (sends to TikTok for review)
- You can also tap "Block" to prevent the commenter from interacting with you again
Bulk delete: tap the pencil icon at the top of the comments section to enter multi-select mode, then choose up to 100 comments to delete at once.
The hidden cost of limiting comments
Before you turn comments off across your account, understand what you're giving up:
- Engagement signal loss — TikTok's algorithm weighs comment count and comment depth as a major ranking signal. Videos with active comment sections get more reach
- Audience research data — comments are the single richest signal of what your audience cares about. Disabling them blinds you to that
- Brand sentiment monitoring — you can't track sentiment shifts on locked threads
- UGC discovery — your highest-LTV customers often introduce themselves in comments. Lock the door and you'll never meet them
A 2023 study on emotion-based purchase decisions found that ~70% of purchase decisions are emotionally driven — and comments are where that emotion lives. Locking comments cuts off your read on how your content lands.
What brands and agencies do instead
Keep comments open. Filter aggressively with keywords (method 3) and TikTok's spam filter (method 5). Then export the comments regularly so you can analyze what's actually happening at scale — beyond what's visible in the in-app view.
The export-and-analyze workflow:
- Leave comments open with keyword filtering enabled
- Once a week (or after a campaign post), export comments using ZocialComment
- Run sentiment analysis on the CSV — flag negative spikes, count purchase-intent signals
- Reply to high-value comments (questions, complaints, top-of-funnel asks)
- Delete or block the ones that slipped through filters
This gives you the moderation benefits of strict filtering without losing the algorithmic boost or the audience insight. Comment sentiment analysis is far more actionable than disabling comments outright.
When you actually should disable comments
There are legitimate cases for shutting it down:
- Sensitive personal content — videos about mental health, grief, abuse where you don't want to moderate strangers' reactions
- Minors' content — TikTok automatically restricts comments on accounts under 16, but verify the setting if you manage a teen creator's account
- Crisis posts — during a PR incident, temporary comment-off can buy you time to prepare a response strategy
- Reupload originals — if you're reposting a previous video and don't want a fresh comment thread, disable comments
In every other case, filter rather than disable.
FAQ
Can I limit who replies to comments on my video?
Not directly — TikTok ties reply permissions to the same setting as top-level comments. If you allow everyone to comment, everyone can reply.
Why are some comments hidden even though I didn't filter them?
TikTok's automated spam filter (method 5) hides comments it judges low-quality or offensive. They appear in the Filtered tab of the comment panel — you can manually un-hide if it's a false positive.
Can I bulk-delete all negative comments on a video?
Not in-app. The pencil multi-select tool only handles 100 at a time and you need to manually pick each one. For bulk moderation, export the comments to CSV first, identify which ones to remove, then go back into TikTok to delete them. ZocialComment's exporter includes a sentiment score so you can sort by sentiment descending and delete the worst N comments.
Does limiting comments to "Friends" actually mean mutual follows?
Yes — TikTok defines "Friends" as accounts you follow that also follow you back. Followers who don't follow you back can't comment.
Can I see comments that I filtered with keywords?
Yes — open the comment panel on any of your videos and tap the Filtered tab at the top. You'll see hidden comments and can approve any false positives.
The right balance
Comments are signal. Disabling them is throwing away your best window into audience reaction for the price of slightly easier moderation. For brands, the answer is almost always: filter heavily, monitor systematically, and export regularly for analysis. Try profile-level analysis to see what's actually being said about your TikTok content over time.
