Do YouTube comments affect brand safety?
Part of YouTube brand safety
The short answer
YouTube comments affect brand safety indirectly. Google's suitability settings judge the main video, and YouTube's advertiser friendly guidelines list the video, thumbnail, title, description and tags, not comments. Comments still sit on the same watch page, fall under YouTube's harassment, spam and child safety rules, and show how a creator manages the audience.
Key takeaways
- Comments are outside the parts of a video that YouTube's advertiser friendly guidelines evaluate, so a monetized video can carry a hostile comment section.
- YouTube turns comments off on made for kids videos and may disable them on compliant videos that depict children or are uploaded by minors.
- What a buyer sees under a video has already been filtered by the creator's moderation settings, so the visible thread is a sample, not the full picture.
- No Google Ads control on the content suitability page targets comments; the buyer's lever is excluding the video or the channel.
Do YouTube comments count when YouTube decides which videos earn ads?
Not directly. YouTube's advertiser friendly content guidelines (opens in a new tab) state that its policies "apply to all portions of your content (video, Short, or live stream, thumbnail, title, description, and tags)." Comments are absent from that list, and the guideline text does not mention them when checked in October 2026. A video can therefore keep full ad earnings while the thread beneath it fills with insults, scam links or arguments the brand would never sponsor.
The advertiser's settings follow the same logic. Google's content suitability page (opens in a new tab) says that "Content suitability settings apply to the main video on the YouTube watch page," and the page did not contain the word comment when checked in October 2026.
Definition
- Comment health
- A working term for how a YouTube channel's comment sections look over several recent videos: whether abuse, spam and off-topic fights stay up, whether the creator replies and moderates, and whether comments are on, paused or off for a stated reason.
Comments matter for a different reason. YouTube's harassment policy (opens in a new tab) "applies to videos, video descriptions, comments, live streams, and any other YouTube product or feature," and the spam policy (opens in a new tab) names comments in its scope too. When an audience keeps breaking those rules and the creator does nothing, the thread says something about the channel that the video does not.
When does YouTube disable comments on videos?
Comments can be off for reasons that say nothing about risk, so a buyer should know the platform's own rules before reading anything into a closed thread. YouTube's page on choosing comment settings (opens in a new tab) states that "Comments are turned off on videos designated as made for kids," and that creators cannot change comment settings on private videos or through a supervised account.
| Situation | What YouTube says | What it tells a buyer |
|---|---|---|
| Video or channel set as made for kids | Comments are turned off; the creator cannot change it | A labeling fact; read the made for kids status |
| Compliant video that depicts children or is uploaded by a minor | Features, comments among them, may be disabled at channel and content level | YouTube judged the content worth protecting |
| Private video | Comment settings cannot be changed | Not inventory a plan would buy |
| Creator turned comments off | Viewers cannot comment on the video | A choice: care on a sensitive video, or avoidance of criticism |
| Creator paused comments | Existing comments stay; no new ones until turned back on | A short term response worth asking about |
The child safety rule has a history. In a February 28, 2019 post (opens in a new tab), YouTube said that "Over the past week, we disabled comments from tens of millions of videos that could be subject to predatory behavior." The few channels allowed to keep comments "will be required to actively moderate their comments, beyond just using our moderation tools." The current child safety policy (opens in a new tab) says YouTube "may also apply stricter display standards to comments, posts, and live chat messages" on such content.
What does a public comment section hide from a reviewer?
The thread a buyer reads has already passed through the creator's filters. YouTube's page on comment settings (opens in a new tab) describes moderation levels from None to Basic, Strict and Hold all, plus lists of hidden users, approved users and blocked words. Its spam page (opens in a new tab) says YouTube detects spam "based on the text of a comment, or by the behavior from a particular commenter," holding such comments for up to 60 days.
| Tool | What it does | Effect on what a buyer sees |
|---|---|---|
| Basic or Strict moderation | Holds potentially inappropriate comments, Strict holding a broader range | Abuse may be missing because it was held, not because it was never written |
| Hold all | Holds all comments until the creator approves them | A clean thread shows the creator's choices, not the audience |
| Blocked words | Holds matching comments, for up to 60 days | Recurring slurs or scam phrases can be caught before they appear |
| Hidden users | Hides a user's comments across all of the channel's videos | Repeat offenders may be invisible to outsiders |
| Who can comment | Limits comments to subscribers and members, with a minimum subscription time | Fewer drive by comments; a smaller, more loyal sample |
So a heavily moderated channel looks calmer than its audience is, which is what a brand wants: the creator is doing the work. Abuse that stays visible despite those tools is the stronger signal, because either the tools are off or nobody reviews what they hold. Outsiders cannot see held comments; the YouTube Data API's commentThreads list method (opens in a new tab) says its moderationStatus filter "can only be used in a properly authorized request."
How can comment health inform a YouTube channel review?
Use comments as one input in the channel review, after the videos themselves have been judged. The channel vetting guide covers ownership, labels and video sampling; the steps below add a comment read to the same sample, so the extra work stays small.
A comment read for one candidate channel
- Use the videos already sampled. Read comments under the same recent uploads chosen for the content review.
- Sort by newest as well as top. Top comments show what the audience rewards; newest show what moderation has not caught yet.
- Look for the creator. Replies or a pinned comment that sets ground rules show an owner who is present.
- Note repeats. The same link, phrase or account across several videos points to spam nobody clears.
- Record the comment status per video. On, paused or off, with the reason where visible, such as a made for kids label.
- Write one dated line of evidence. Quote the pattern, not a single comment.
Keep the weight proportionate. Rowdy but harmless comments under videos that fit the brief do not remove a channel. Threats, doxxing or sexualized remarks under videos of young people do, because YouTube's own policies prohibit them.
What comment signals suggest a risky YouTube channel?
Comment signals worth a closer look before approving a channel
- Threats, personal information about named people or dehumanizing insults stay visible across more than one video.
- The creator's pinned comment or video urges viewers to go after a named person, the brigading the harassment policy describes.
- Identical promotional messages or scam links repeat under several uploads.
- Comments under videos that feature children dwell on their appearance.
- Comment status changes across the channel with no explanation, such as new uploads closed after a public dispute.
| Pattern | Strength as a signal | Limitation |
|---|---|---|
| Harassment or doxxing left up | Strong: policy breaking behavior tolerated | May reflect one viral video |
| Repeated spam and scam links | Moderate: nobody clears the thread | Spam reaches large channels regardless of content |
| Heated debate about the topic | Weak: normal on news, sport and politics | Easy to mistake engagement for risk |
| Comments off | Neutral until explained | May be a YouTube rule or editorial care |
A low comment count beside very high views belongs with the inflated engagement checks in the fake views guide. A weak signal alone should lead to a look at more videos, not to an exclusion.
Can advertisers control whether their ads appear near YouTube comments?
Not as a separate setting. When checked in October 2026, Google's content suitability page described inventory types, content type exclusions, excluded placements, themes and keywords, all judging the video rather than the discussion under it, and said "we can't guarantee that all related content will be excluded." A buyer has two levers: the video and the channel.
Google's page on excluding webpages and videos (opens in a new tab) lets advertisers exclude a placement by video ID at the campaign, ad group or account level, which fits one upload whose thread went bad. A channel wide pattern belongs on a list, covered in the channel exclusion list guide. Neither step moderates comments; both take the brand's money off the page.
What does a comment read look like on a real YouTube plan?
Fictional example
An acoustic guitar maker in Kentucky
A fictional acoustic guitar maker based in Kentucky runs a YouTube plan for buyers in Louisville and Lexington, on guitar lesson, gear review and bluegrass performance channels. The brief avoids harassment and spam heavy environments.
A lesson channel with strong videos has comments off on all of its recent uploads. Its videos show a family duo in which a child plays, and several carry the made for kids label. The planner records that comments are off under YouTube's rule and flags the channel for the client's made for kids decision, not for its comments.
A gear review channel fits the brief, but the newest comments under three recent uploads carry the same scam link and attacks on a rival reviewer, with no reply from the creator. The planner excludes those three videos by video ID, notes the pattern with the date, and schedules a second read before the next flight.

Frequently asked questions
Can a buyer see comments a creator is holding for review?
No. Held comments are not public, and the YouTube Data API's comment thread method says its moderation status filter can only be used in a properly authorized request. A buyer reads only what the filters let through, so abuse that survives moderation carries more weight than a quiet thread.
Does a pinned comment count toward a video's ad eligibility?
YouTube's advertiser friendly guidelines apply to the video, thumbnail, title, description and tags, and comments are not on that list. A pinned comment still sits under the video and falls under the Community Guidelines, so a pinned link or attack belongs in the channel review notes.
Are live chat messages judged the same way as comments?
YouTube's harassment policy covers comments and live streams, and its child safety policy says YouTube may apply stricter display standards to comments, posts and live chat on content that depicts children. For live inventory, read a past stream's replay chat where YouTube shows it.
Should a brand ask sponsored creators to moderate comments?
It is a reasonable term to agree in writing for a sponsored video, because the brand's name is in the video itself. The creator controls settings such as Hold all or blocked words, so the agreement can name the setting and who reviews held comments during the flight.
