The question, “Can you turn off commenting on Facebook ads?” is appearing more frequently as businesses seek to maintain a clean and low-risk interaction environment. Inappropriate comments, spam, or misinformation can all affect communication effectiveness, making the need for control increasingly evident. During campaign construction, many entities review their operational procedures and ask themselves, “Can you turn off commenting on Facebook ads?” to preserve message consistency and protect brand reputation. The content below will provide clear and easy-to-apply methods for handling this.
When to consider turning off comments on ads
The decision to turn off comments should not be based solely on intuition but must stem from clear factors related to information security and campaign stability. When an ad starts to attract significant interaction, the quality of the comments directly impacts brand perception and viewer behavior. Therefore, monitoring for abnormal signs is necessary to determine when intervention is needed.

Signs that comments are having a negative impact
Comments containing aggressive content, spreading misinformation, or spam are clear indicators that the ad is facing issues with interaction control. When the frequency of these comments increases rapidly and appears in a chain, a crowd effect can form, attracting more negative opinions.
This disrupts the ad’s information flow and significantly reduces viewer trust. Furthermore, if comments continuously focus on sensitive issues or generate tense user debates, the ad easily loses its ability to guide the original message.
At this stage, turning off comments or switching to automatic filtering is a way to minimize impact and prevent bad content from spreading.
Industries prone to risk with public comments
Certain highly sensitive industries often face risks when allowing public comments. The healthcare, supplements, or health-related products industries are often heavily questioned about safety and effectiveness. This leads to many challenging or suspicious comments, some of which are purely speculative.
The finance industry faces a similar situation when viewers may share negative experiences or misunderstand policies, affecting credibility.
New technology products, especially devices with complex features, are easily debated by users regarding quality and technical faults. In industries like retail or cosmetics, ad spam comments or irrelevant links also appear frequently.
Identifying these characteristics helps advertisers build a tighter comment control strategy, limiting negative impact from the campaign’s initial stages.
Methods for controlling comments within the Facebook ads system
Controlling comments on Facebook ads requires a clear process to maintain display quality and limit risks from unwanted interactions. Each brand has a different tolerance level for negative comments, spam, or misleading content.

The operation of turning off comments in Ads Manager
Turning off comments is the method used when the campaign aims for a clear conversion objective and does not prioritize public interaction. In Ads Manager, the advertiser can adjust the interaction mode within the settings of each ad.
When the comment mode is locked, the system stops displaying the comment input box for users. This approach eliminates the risk of spam or inappropriate discussions appearing while the ad is running.
However, businesses need to consider this, as turning off comments also means reducing the opportunity to generate social proof signals that boost credibility.
Manual comment control
Manual control is suitable when the volume of comments is not too large and the operations team has sufficient time to monitor. This method focuses on reviewing and processing comments after they have appeared.
On a phone, the administrator can press and hold the comment to be hidden and select the hide action. This is especially convenient when the operations team is monitoring on a mobile device and needs to process quickly. On a computer, a similar operation is performed by hovering over the comment, selecting the options icon, and proceeding to hide. Hidden comments are still visible to the commenter themselves, but will no longer appear to the majority of followers.
For posts that are not part of an ad campaign, the administrator can restrict who is allowed to comment through the public post settings in the account management section. This does not completely disable commenting, but narrows the scope of who can reply. When selective interaction needs to be maintained, this is a suitable solution to optimize the ad’s display quality.
Using third-party tools
Third-party tools help automate comment control, especially when the number of campaigns is large or multiple accounts are running concurrently. These platforms often provide capabilities for keyword filtering, content tagging, detecting abnormal behavior, and sending real-time alerts.
Additionally, they support the centralization of comments from multiple ads into one interface for easier processing by the operations team. When high-scale management is required, integrating external tools can significantly reduce manual workload and minimize human errors. However, businesses need to choose a reputable platform and ensure compatibility with the Facebook API to avoid synchronization errors.
Adjusting roles and permissions to maintain control
The permission structure plays a crucial role in comment control, especially with large teams or when multiple vendors are involved. Establishing appropriate roles helps prevent incorrect editing permissions or accidentally deleting important data. The administrator should allocate permissions by task; for example, the comment moderator is allowed to hide but not allowed to edit the ad. This clear separation helps ensure all operations are tightly controlled, preventing unqualified accounts from performing sensitive tasks. When there are personnel changes or new units join the operation, the permissions need to be reviewed to prevent risks.
Setting up automated filters for sensitive phrases

Automated filters are a preventative control option, operating before comments appear publicly. The advertiser can list phrases related to spam, malicious content, or conflict-prone words and add them to the filter list.
When a comment contains these phrases, the system will automatically hide it to avoid impacting other viewers. The filtering mechanism creates an extra layer of protection for campaigns with high brand risk or those that frequently encounter negative comments.
For high effectiveness, the keyword list needs to be updated periodically, based on new variations that users might create. When the filtering system is set up correctly, businesses can reduce the manual control workload and maintain a more stable feedback environment.
Step 1: Go to the Page settings
In the Page interface, select Settings. Here you will see options related to privacy, control, and content.
Step 2: Access the Page moderation section
In the left-hand list, select Page Moderation. This is where you can input the list of keywords you want Facebook to filter automatically.
Step 3: Enter the list of phrases to block
Fill in the keywords or phrases that, when they appear in a comment, the system will automatically hide. You can add multiple words at once and update them whenever needed. The list should include:
- Offensive language
- Sales spam
- Competitor brand names, if a restriction is needed
- Variations of the same word to prevent slipping through the filter
Step 4: Activate the high moderation filter
In addition to the manually entered keyword list, Facebook has a High Moderation Filter option. When this mode is enabled, the system automatically detects and hides comments that the algorithm deems sensitive. This is an additional layer of protection alongside the self-established list.
Step 5: Monitor and update periodically
The keyword list needs to be checked and expanded over time. Users may create new variations or use evasive words, so updating helps prevent unwanted content from being missed. A review should take place once a month or once per campaign phase to ensure effectiveness.
Frequently Asked Questions
Why, despite sufficient filtering, is bad data still entering the target group?
The learning system is based on real behavior, not a fixed checklist. If a new user exhibits behavior closely resembling the target group, they can still be pulled in.
There is no 100% benchmark, but generally, when volatility decreases, CTR stabilizes, CPA gradually lowers, and the conversion chart no longer jumps wildly hour-to-hour, that is a sign that the data has smoothed out.
