Can you turn off comments on Facebook ads? For most advertisers, no

For most advertisers, no: Meta Ads Manager has no documented switch that turns comments off on a Facebook ad. As of September 17, 2026, Meta has been testing a comment control "available to a limited number of businesses" since October 2024, and its help pages still describe comment moderation rather than an off switch; if your account has the control, third parties place it in the ad set's placement settings.

Below: what Meta itself says and where to look in your own account, why comments are on by design, the one real off switch, the Page filters that reach your ads, hiding on the ad itself, what an off switch would have cost me, and the rule that keeps an ad clean with comments on.

What Meta actually says

Meta's announcement from Advertising Week, October 2024, read September 17, 2026: "Today, we're announcing that we're testing a new control that allows businesses to turn off the comments on their Facebook and Instagram ads. We understand this functionality can be important for brands when running sensitive campaigns or during periods of heightened sensitivity. Comment controls are currently available to a limited number of businesses, and we will continue to test and iterate on this functionality and its availability."

Nearly two years on, the help pages have not caught up with the announcement. Meta's page on managing ad comments, read September 17, 2026, describes hiding, reporting and the Page filters and never mentions turning comments off. Its two pages on the inventory filter, read the same day, do not contain the word "comment".

What the ranking pages add is unsourced but consistent: two moderation vendors, writing in late 2025 and mid 2026, place the control in the ad set editor under Placements and Inventory filter, as Comment controls with two options, Public and No One, and both say most accounts do not see it. That is where to look. I have asked for the check on my own ad accounts, and the screen, with or without the control, goes here when it is in.

Why there is no switch for most accounts

Comments on ads are the design, not an oversight. Meta's ad-comments page: "For most advertisers, anyone who can see your Facebook, Instagram or Threads ad can react to it or comment on it. Comment moderation is designed to help you manage comments on your ads and moderate discussions about your brand, product or service."

Its best-practices page for ad comments, read September 5, 2026, says the same from the other side: "Comments are a way people connect, debate and discuss on Facebook. As brands, you can moderate comments on ads that appear on Facebook." Everything Meta documents for an advertiser is a way to moderate, and the rest of this page is those ways.

Turn comments off on a boosted post

The one off switch that exists on Facebook belongs to a post, not an ad. A Page post carries its own comment setting, and a boost promotes that post with the setting it has; turn commenting off on the post first and the boosted version keeps it. The per-post audience menu that limiting comments on Facebook describes is the same idea one step short of off.

Two limits. An ad built in Ads Manager from scratch has no Page post to switch, and a boosted post with comments off has none of the questions either, which is the cost the section below counts.

The Page's filters that extend to ads

Meta's best-practices page: "You can proactively moderate comments by blocking words or applying a profanity filter. When these features are enabled, comments containing these keywords or profanity are hidden. These features are set at the Page level and extend to ads from the Page." The word list takes up to 1,000 keywords, emojis included, and the same page recommends it: "Use the Page comment moderation tool for Inbox to block posts or comments containing specific words. Emojis are supported and treated like a text character."

Moderation Assist is the third filter, and Facebook's page for it says its criteria hide comments "on your Page, profile or ads that you run". What Moderation Assist hides and leaves has every criterion; the ones that matter under an ad are the link, the keywords and the empty-account rows.

The trick the vendors suggest, blocking every common word so that nothing gets through, works and hides your customers with the spam; a list that catches "price" catches "what's the price?".

Hide or delete comments on the ad itself

For what the filters miss, Ads Manager reaches the ad's comments directly. Meta's page, read September 17, 2026: open Ads Manager, find the ad on the Ads tab, click the three dots beside its name, choose More options and then "Manage Facebook comments". "A pop up will open, showing your ad with people's reactions and comments or replies", and on any of them you "select ... to the right of any comments or replies you consider inappropriate to Hide comment or Report comment".

One note from Meta's partnership-ads page, read September 17, 2026, for anyone running creator ads: "At this time, only creators can delete comments on partnership ads. Advertisers cannot delete comments on partnership ads."

What turning comments off would cost

Here is the count from my own Facebook ads, September 1 to 17, 2026, taken on September 17: 576 comments arrived under ads, 489 were removed, and 114 are still visible. A random sample of the visible ones reads like this: "Can you guys implement Meta API cloud", "Hola, tiene lectura OCR para códigos QR?", "Who has tried this app?", "Is this true?", a request for details in Arabic, "Great", "Nice", "Hi".

An off switch would have removed the 489 and the 114 together. The 489 were spam a rule removed anyway; the 114 are the prospects asking whether the product does what the ad says, in four languages, under the ad that reached them. That is the whole case against the switch, and it does not depend on any claim about reach.

A rule instead of a switch

CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts. Its rules run on the ad's comments as they arrive, so the link, the gambling paste and the "DM me" go before a prospect reads them and the question stays, and one control decides whether the rules apply to ads, posts or both; ads only, posts only or both is the guide.

Facebook ads and Instagram ads

Facebook's cells come from Meta's help text (read between September 5 and 17, 2026); Instagram's are a summary until its own article.

Common questions

Can you turn off comments on Facebook ads?

Not with a documented switch, as of September 17, 2026. Meta's ad-comments help page says "anyone who can see your Facebook, Instagram or Threads ad can react to it or comment on it", and its October 2024 announcement describes a comment control "available to a limited number of businesses". If your ad set's Placements section shows Comment controls, your account is one of them.

Can you turn off comments on a boosted post?

Yes, on the post. Turn commenting off on the Page post first, then boost it; the boost carries the post's comment setting. An ad built in Ads Manager from scratch has no Page post to switch.

Does turning off comments hurt ad delivery?

Meta's help pages say nothing about delivery either way and no figure of mine bears on it, so the question stays open here. What can be counted is what an off switch silences: under my ads in September 2026, 114 visible comments, most of them questions and short praise.

How do I keep spam off my ad comments without turning them off?

Turn on the Page's profanity filter and word list, which extend to ads, add Moderation Assist's criteria, and let a rule that reads the comment hide or delete the rest as it lands. CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts.
