Can you turn off comments on Facebook ads?
Mostly, no. Facebook’s setting for who can comment on a Page post is not available once the post is an ad or boosted. You can hide comments on an ad, and your Page’s profanity filter and blocked words do apply to your ads — but the comment box stays open.

Meta’s own tools
What Facebook lets you do on an ad
-
Hide comments from Ads Manager
Open the Ads tab, edit the ad, click … next to its name, then More options → Manage Facebook comments (or Manage Instagram comments). On Facebook you can like, reply, hide or report a comment; on Instagram, hide or report. Meta’s steps
-
Turn on the profanity filter
From your Page: Settings & privacy → Settings → Followers and public content, then Hide posts and comments with profanity. Meta says filters set at Page level extend to your ads. The word list behind it is Meta’s and is not published. Meta’s steps
-
Add blocked words
On the same screen, Hide comments containing certain words from your Page. Up to 1,000 words, phrases or emoji, and Facebook also hides common variations of them — misspellings, numbers for letters. Matching comments are hidden, not deleted. Meta’s steps
-
On Instagram ads, use Hidden Words
In the app: Menu → How others can interact with you → Hidden words. Meta says these extend to your ads too. Meta’s steps
What does not reach your ads
Moderation Assist — Facebook’s rules for comments from brand-new accounts, accounts with no profile photo, links and the like — does not hide comments on any ads you run (Meta). And the who can comment setting on a Page post stops being available once that post is an ad or boosted (Meta).
What about an off switch? In October 2024 Meta started testing comment controls in Ads Manager, under an ad set’s placement inventory filter, with a limited number of businesses. We could not find that option on any current Meta help page. If your ad set shows it, it is the only real way to close comments on an ad.
Instagram posts and Reels can have commenting turned off from their options menu (Meta). Meta does not document whether that survives boosting the post, so test it on one post before relying on it.
Why it matters more on ads
Hiding beats switching comments off
A scam link under an ad you are paying to show is someone else collecting your traffic at your expense — and the better the ad performs, the more it collects.
The same thread is where buyers ask about sizes, shipping and price. Closing comments, where you can, silences those too. Hiding what breaks your rules keeps the questions up and the spam out of sight: a hidden comment stays visible to the person who wrote it and their friends, and to no one else.
Where the native tools stop
Enough for one ad, not for a campaign
For one Page running one ad, Meta’s tools are enough and you should not pay anyone for this.

How CommentDefender handles ad comments
Connect the Page
Sign in with Facebook and pick the Pages your ads run from. The Instagram professional account linked to a Page comes with it. No ad account access is needed.
Set rules per Page
Links, emails and phone numbers, your keyword lists, and a whitelist that overrules them. Try the rules on a real comment before you sign up.
Matches are hidden in seconds
Every new comment on your posts and ads is checked as it arrives, and every hide is logged with the rule that caused it.
Before you sign up
Two things this does not do
It does not turn comments off either. It hides the comments that break your rules and leaves your buyers’ questions where they are.
It does not clean up comments already on your ads. Moderation starts at the moment you connect a Page.
