To block competitor comments on Facebook ads, list the rival names and pitch phrases you want gone, hide what is already under your ads, ban repeat offenders, and load the list into your Page's blocked words. Then add moderation that reads intent for the pitches a word list misses, and review what got hidden every week.
Competitor comments cost you twice: you pay to put the ad in front of a shopper, and a rival uses your comment section to pitch the person you paid to reach. The steps below start with Meta's own tools. Menus move often, so check each step against the Meta help pages linked along the way.
Step 1: Build a competitor watchlist before you touch any settings
Every filter you set later is only as good as the terms behind it. Start a spreadsheet with these columns of competitor identifiers:
Brand names and product names
Founder and spokesperson names
Domains and short links
Social handles
Workarounds rivals use to dodge filters, such as a domain written out with dot com
Next, open the comment sections of your five highest-spending ads and read them. Copy real examples into a second tab and tag the pattern: link drop, switch-to-us pitch, discount code, fake customer review, or fake complaint. Patterns matter more than names. A rival who never writes their brand name but posts DM me for a better deal will slip past a name list, and you will want those phrases captured too.
Then decide your policy before you start clicking. You have three tools: hide, delete, and ban. Write down which one applies to which behavior. A reasonable default is hide for promotional competitor comments, delete for scams and explicit spam, and ban for repeat offenders.
Draw one line clearly. A competitor promoting themselves is not the same as a genuine customer asking how your product compares to a named rival. The first is ad-space hijacking. The second is a buying question from someone comparing options, and it should usually be answered, not removed. Put this distinction in your written policy so anyone moderating for you applies it the same way.
Step 2: Confirm your access and find the ad comments
You can only act on comments if your access allows it. Meta's comment moderation tools for Pages require Facebook access to the Page, so check that you have it. If you work through an agency or a business portfolio, confirm that access is granted on the Page itself, not only on the ad account.
Then find where ad comments live. As of October 2026, Meta's guide to managing comments on your ads gives this route in Ads Manager:
Open the Ads tab, find the ad, and click Edit below its name.
In the left column, select the three dots next to the ad name, then More options.
Choose Manage Facebook comments. A pop-up shows the ad with its comments, where you can reply to, hide, or report each one.
Meta says the same tools are also available from your Facebook notifications. Ads can also run on Page posts created in Ads Manager that never appear on your Page's timeline, often called dark posts, and Meta notes that people can still like and comment on them when they appear as ads. The post never shows on your Page, which is exactly why nobody on your team notices what is happening there.
The mistake to avoid: checking only your organic feed and concluding everything is clean. Open the comments for every active ad, not just the creative you think of as the main one. A rival only needs one thread that nobody checks.
Turning comments off is a blunter option, covered in how to turn off comments on Facebook. Even where it is possible for an ad, it removes social proof along with the competitor noise, so this guide sticks to selective control.
Step 3: Hide or delete the competitor comments already there
Before you remove anything, screenshot each offending comment and log the profile name, the ad it appeared under, and the date. That evidence helps if you later report a repeat offender or a fake-review campaign.
Now choose the action. Meta's help page on hiding Page comments describes how the two options behave:
Hide: the comment stays visible to the person who wrote it and their friends, and is hidden for everyone else, including the shoppers your ad reaches. Its replies are hidden with it.
Delete: the comment is removed from the post. Its author may notice it is gone and post it again.
Make hiding your default for competitor promotion. It takes the pitch away from the people you paid to reach, and Meta notes that hiding can help prevent more unwanted comments. Reserve deletion for explicit spam, phishing links, and scams, where you want no trace left under your ad, and where a repost is easy to handle with a ban in the next step.
Work in order of spend. Start with the ad that is consuming the most budget, because the most people see its comments, then move down the list. Within each thread, check replies as well as top-level comments. A rival can tuck a pitch into a reply under a genuine customer question, right where your future buyer is looking for the answer. Hide that reply on its own rather than the question above it, since hiding a comment also hides its replies.
If a comment is from a real customer who names a rival, leave it and reply instead. Your policy from Step 1 covers this. Removing honest comparison questions makes an ad look curated, and the shopper who asked walks away without an answer.
Step 4: Ban repeat offenders from your Page
Hiding clears the comment. Banning deals with the profile behind it. Meta's own best practices for comment moderation on ads say to ban people who continually publish spam on your Page, so when a profile shows up on several ads or posts a second pitch after you hid the first, ban it.
In current Page settings the control is called blocking. As of October 2026, Meta's guide to blocking someone from your Page lists these routes on a computer:
Page settings: Settings & privacy, then Settings, then Blocking
Your Page's list of followers
The commenter's photo on one of your Page's posts
Meta says a blocked profile can no longer see your posts on your timeline, tag your Page, invite it to events or groups, or start a conversation with it.
The limitation is just as important. Rivals can open new accounts or ask a colleague to do the commenting. When you block a profile, Meta lets you also ban new profiles the person may create, but it notes that it may not be able to detect all new accounts. A ban will not stop a determined rival on its own, which is why Steps 5 and 6 exist.
Report the worst of it. Meta's best practices say to report comments or people you believe could violate its Community Standards, and the menu that hides an ad comment in Ads Manager also offers Report comment. Impersonation of your brand or staff, scam or phishing links, and harassment of your customers are the cases most worth reporting. Log each report with the date. Do not argue with the competitor in the thread, since a public reply only draws more attention to the pitch.
Step 5: Block competitor comments on Facebook ads with keyword filters
Manual cleanup only fixes what you have already seen. Native filters hide new comments automatically. Facebook lets a Page hide comments that contain words you choose, and a profanity filter hides the words and phrases the community most often reports as offensive. Meta's ad comment guide says these filters are set at the Page level and extend to ads from the Page. A hidden comment stays visible to the person who wrote it and their friends.
As of October 2026, you can block up to 1,000 keywords, including phrases and emoji, under your Page's Settings in Followers and public content. Meta also hides common variations automatically, such as misspellings, plurals, abbreviations, and words written with numbers or symbols, so you do not need to type every spelling yourself. For a fuller walkthrough, see our guide to the profanity filter and blocked words.
Load your watchlist from Step 1: competitor brand and product names, domains in the forms people actually write them, and pitch phrases such as use my code and DM me for.
Then watch what still gets through. Rivals adapt, and a word list only knows the words you gave it. After a week, look at the comments that slipped past and add the wording they actually used, such as a domain written out with dot com.
The main risk is going too broad. If you block a generic word, or your own category name, you will hide legitimate customer questions without noticing. Suppose you sell running shoes and block the word cheaper. You will hide shoppers asking whether a cheaper model exists, which are exactly the comments you want to answer. Start with a short, specific list, then review what gets hidden after a week and prune anything catching real customers.
Know where word lists stop. A blocked-word list hides any comment that contains a word on it, so a pitch that uses none of those words, such as message me for a better deal, goes straight through. It also cannot tell a rival's pitch from a customer's honest question when both contain the same competitor name, so both get hidden. That gap is where automation helps.
Step 6: Automate moderation so it works around the clock
Manual review breaks for a simple reason: ads do not stop at 6 p.m. Campaigns run overnight and across time zones, and a competitor pitch posted at 2 a.m. can sit under a paid ad for hours in front of the people you are paying to reach. Keyword filters run around the clock, but they cannot read intent.
An AI moderator closes that gap by classifying each comment instead of matching words. Exerta's comment moderation reads what each comment means, hides the spam and pitches that hurt the ad, and answers the genuine questions under your Facebook ads. A pitch worded in a way no keyword list anticipated can still be hidden, and a customer who names a competitor while asking a real question can get a reply instead of a hide. Exerta is a Meta Business Partner built on the official APIs, not scrapers.
If you are comparing options, several other providers moderate comments on paid and organic posts, Facebook included: NapoleonCat, BrandBastion, Respondology, and CommentGuard. Evaluate them on the same criteria. Does it moderate comments on ads, including dark posts, as well as organic posts? Does it decide by intent or only by keywords? Can you set different actions for competitors, spam, and scams? Is there a review queue and a log of what was hidden? Check each vendor's own site for current features and pricing, and test it on a live ad if you can.
Whatever you choose, keep a human review queue for edge cases. The customer who writes that they are comparing you with a named rival and asks a real question should reach a person or a considered reply, not a silent hide.
Step 7: Monitor results and tune your rules
A filter set that works in week one will drift as rivals change tactics. Put a 10-minute review on the calendar every week and do three things: scan the hidden comments for false positives, add any new competitor terms or pitch phrases you spot, and open the comment threads of any ads you launched that week. On a Page post, Meta lets you sort comments by Hidden by This Page to see what you hid along with what the profanity filter and your blocked words caught, then unhide anything that should stay.
Measure against your own account instead of industry averages. Useful signals include the share of comments on your ads that were removed or hidden, how long genuine questions wait for a reply, and click-through rate and cost per purchase on top ads, compared across the weeks before and after cleanup. Treat any change in cost per purchase carefully, since creative fatigue, seasonality, and budget shifts also move it. Compare similar periods and change one thing at a time where you can.
Before a new creative starts spending, add any rival names or phrases specific to that product to your list, and put a first-day comment check on your launch checklist.
Finally, use the cleaner threads to sell. Genuine questions about price, sizing, shipping, or how you compare are buying signals. Answer them in the thread, where the next shopper reading the ad can see the answer too.
FAQ
What is the difference between hiding and deleting a competitor comment?
Hiding keeps the comment visible to the person who wrote it and their friends, and hides it from everyone else, including the shoppers your ad reaches. Deleting removes it from the post entirely, so its author may notice and post it again. Hide competitor promotion by default and keep deletion for scams and explicit spam.
Should I remove a comment that just mentions a competitor by name?
Not if it is a genuine customer asking how you compare. That is a buying question and deserves a reply, not a hide. Reserve removal for comments that are actually promoting the rival, such as switch-to-us pitches or discount codes for another brand.
Can banning a competitor's profile stop them for good?
No. Meta says a profile blocked from your Page can no longer see your timeline posts, tag your Page, or start a conversation with it. You can extend the ban to new profiles they create, but Meta may not detect them all, so pair bans with keyword filters and a weekly review.
Do Facebook's native keyword filters catch everything?
No. A blocked-word list hides comments containing your terms and the common variations Meta detects, but a pitch that avoids those words gets through. It also cannot tell a rival's pitch from a customer's honest question when both use the same competitor name. That gap is where a moderation tool that reads intent helps.
How often should I update my competitor watchlist?
Weekly is reasonable for an active ad account. Rivals change their wording to dodge filters, so a short recurring review, scanning what got hidden and adding new phrases, keeps the list effective without taking much time. Also update it the day you launch new creative or notice a new rival advertising to your audience.
