You wrote the headline. You picked the image. You argued with yourself about the offer for two days. Then you put money behind it, and Meta attached a comment section to the bottom of your work and handed the pen to everyone who scrolled past.
That comment section is not a side effect of advertising on Meta. It is part of the ad. It sits inside the same bordered box, in the same feed, under the same brand name, and the person deciding whether to trust you reads it in the same breath as your copy. Most owners we talk to have never once opened it.
The Second Headline You Did Not Write
There is a reason a stranger's sentence carries more weight than yours, and it is not fair, but it is very human. Your copy is paid for. Everybody knows it. The comment underneath is not, or at least it does not appear to be, and that is enough for a reader to treat it as the more honest of the two.
So the sentence "does this actually work or is it another scam" does not land as one person's opinion. It lands as the verdict of the crowd, sitting directly beneath your claim, unanswered. And an unanswered question in public reads as a question you could not answer.
The flip side is the part worth getting excited about. A real customer replying "used these guys in March, they showed up when they said they would" is doing work your budget cannot buy, in a place where your budget put it. That is the whole opportunity here. You are already paying to get eyeballs onto that box. What those eyeballs find at the bottom of it is one of the few things left that costs nothing.
Nobody Can Find the Comments
Here is the practical reason this gets ignored, and it is not laziness. The controls are buried.
Meta's own documentation states that for most advertisers, anyone who can see your Facebook, Instagram or Threads ad can react to it or comment on it. Comments are on by default. But to actually see them, the path in Ads Manager runs like this: open the Ads tab, find your ad, click Edit below the ad name, look at the column on the left, click the three dots to the right of your ad name, choose More options, and then, depending on your objective and where the ad is running, you may see Manage Facebook comments, Manage Instagram comments, or Manage Threads replies.
Six steps, and the last one says "may see." That is not a surface anyone stumbles onto. If you have never found it, the tool is doing that, not you.
The practical fix is to stop treating it as something to go and check and start treating it as something that comes to you. Those same conversations show up in your Facebook and Instagram notifications. For most small businesses that is the realistic system: not a daily audit, just noticing.
You Can Reply on Facebook. On Instagram You Can Only Hide.
This next part surprises people, and it changes what you can promise yourself you will do.
Inside that comment management pop-up, the actions are not the same across platforms. On Facebook you can like comments and reply to them. On Facebook, Instagram and Threads you can hide a comment or report it. Read that again, because the gap is the whole point: replying and liking are listed for Facebook. On Instagram and Threads, from that surface, your options are to make it disappear or to escalate it.
If your plan was "I will just answer the objections as they come in," that plan works on Facebook. On Instagram it needs a different route, through the Instagram app or your connected professional account, and it needs somebody who actually has access to it.
If You Run Ads as Your Page, Your Instagram Comments Are Not Yours
This is the one that catches small businesses hardest, and I have never seen it written down anywhere an owner would find it.
Meta's documentation is explicit: you cannot manage comments on Instagram if you have not connected an Instagram profile, meaning you are running ads using your Facebook Page identity. The same applies to Threads replies without a Threads profile.
Sit with what that means. Plenty of local businesses set up Meta ads through their Facebook Page, tick the box that puts the ad on Instagram too because more placements sounds like more reach, and never connect an Instagram account because they do not really use Instagram. Their ads then run on Instagram, collect comments on Instagram, and those comments are not manageable by the person paying for them.
If you are running Instagram placements, connect the Instagram account. It takes minutes and it is the difference between owning the conversation under your ad and not being in the room.
Hide Is Not Delete
These two get used interchangeably in conversation and they do very different things.
Hiding a comment makes it visible only to the person who wrote it. From their side nothing happened. Their comment is still sitting there, they have not been censored, and there is no fight to pick. From everyone else's side it is gone. Meta's own guidance is to review your hidden comments periodically and decide whether to keep them hidden, unhide them or delete them.
Deleting removes the comment completely, and people notice. Someone who typed something rude will shrug. Someone who typed a genuine complaint and watched it vanish will type it again somewhere with a bigger audience.
The rule that holds up: hide the noise, answer the criticism. A specific, fixable complaint deserves a reply, in public, where the next hundred readers can see that a real person responded. Save hiding for what is genuinely abusive, off-topic or spam, and reach for delete rarely.
The Scam Replies Are the Real Leak
Ask a local business owner what actually happens in their ad comments and you will not hear about criticism. You will hear about the fake accounts.
The pattern is familiar: an ad for a service gets a reply from an account using a lookalike name, telling people to message a different number for a better price. That is not a public relations problem. That is somebody standing next to your paid reach, intercepting the customers you just bought.
Meta has an automation tool for this called Moderation Assist. It is documented as a tool for creators managing a Page or profile in Professional Mode, and the documentation confirms it applies to your Page, your profile, or ads that you run. You set criteria and a virtual moderator hides matching comments automatically.
What it can hide based on the person commenting: someone with no profile picture, someone with no friends or followers, an account less than a week old, someone who has had at least three comments reported, deleted or hidden by an admin in the past thirty days, and accounts that may be using a fake identity.
What it can hide based on the comment itself: anything containing a link, a link to a specific site, an image, a video, custom keywords, or profanity.
Look at that first list against the scam pattern. No photo, no friends, account created last Tuesday. Those filters were built for exactly this.
Two limits worth knowing before you rely on it. It only hides comments made after you create the criteria, so setting it up does not clean out what is already there. And you need to be switched into your Page or main profile to use it. One more useful detail: custom keywords catch variations, so adding a word also catches the spaced-out, punctuated and misspelled versions people use to slip past filters.
Set the Filter Once, at the Page
The proactive controls are not per-ad, and that is good news for anyone dreading another recurring task.
Meta's guidance is clear that blocked words and the profanity filter are set at the Page level and extend to ads published from that Page. Turn on the profanity filter once and it covers everything you run. Add a blocked word list once and the same applies. Emojis are supported and treated like a text character, which matters more than it sounds, because a certain category of comment is mostly emojis.
This is a fifteen minute job you do a single time. It will not catch a well-written complaint, and it should not. It catches the sludge.
The Reply Is Ad Copy You Are Not Paying For
Every published best practice Meta lists starts from the same place: address comments directly, both negative and positive, to show the brand is listening. That sounds soft until you think about who is actually reading.
The person who left the comment is one reader. The people who will read your reply and never type anything are the hundred behind them. When someone asks "how much is this roughly" and you answer with a real range, you have not answered one person. You have answered every silent reader with the same question, in public, using words a stranger will believe more readily than the same sentence in your ad copy.
This is the closest thing to free performance improvement in the whole account. It costs a few minutes and it lifts the credibility of an ad you are already paying to distribute. If you are running Meta campaigns and you are looking for something to improve this week that does not require new creative, a new budget or a new Meta ads strategy, this is it.
Reuse the Post and the Comments Come With It
There is a mechanic here that turns comment management from housekeeping into something that compounds.
When you move a winning ad into another campaign, using the existing post rather than uploading the creative fresh keeps the likes, comments and shares it has already earned. We have written about this before as a delivery matter, in Meta Won't Give Your New Ad a Fair Shot. The comment angle is the other half of it.
An ad that has run for months carries a comment thread. If you have been answering questions in it, that thread is a growing body of public proof that travels with the creative into every new campaign. It gets better with age.
And it carries the bad ones too. The complaint you left sitting there in June rides along into your September campaign, still unanswered, still the first thing a careful reader sees. The compounding runs in both directions, which is the real argument for dealing with things when they appear.
Partnership Ads Play by Different Rules
If you run partnership ads, the ones where you put budget behind a creator's post, the permissions are not what you would assume.
Meta's documentation says creators and advertisers can hide, delete or add comments on partnership ads through Ads Manager, and then adds a specific limitation: only creators can delete comments on partnership ads. Advertisers cannot. You can hide, and you can add a comment of your own, but deleting stays with the creator.
That is worth settling before the campaign runs rather than during it. If you are paying to amplify someone else's post, agree upfront who is watching the comments and who acts. We covered the wider version of this arrangement in You Don't Need an Influencer. You Need Permission, and comment control belongs in that same conversation.
What to Do This Week
None of this needs a project. It needs about twenty minutes and then occasional attention.
Turn on the profanity filter at your Page and add a short blocked word list, remembering it covers every ad you run from that Page. If you are buying Instagram placements, connect your Instagram account so the comments there are actually yours to manage. Open one live ad through Ads Manager and look at what is sitting under it, because there is a decent chance you have never seen it. Answer anything that is a real question. Hide the junk. Leave the criticism visible and reply to it like a person.
Then let your notifications do the work. You do not need a daily audit. You need to stop being the last to know what is written under your own advertising.
We run Meta campaigns for small businesses all day, and the comment section is one of the first places we look when an account is spending fine and converting badly. If you would rather hand that over and get back to running the business, we are happy to take it. If you would rather do it yourself, everything above is the whole method, and it works.
