The honest answer first: Facebook does not give Pages a simple off switch for comments on every post. What it gives you is a set of narrower controls — limiting who can comment on public posts, keyword filtering, and hiding or deleting individual comments. Groups are the exception: group admins can turn off commenting on a specific group post.
What Facebook lets you control
- Limit who can comment on a public post, for example to profiles and Pages you mention.
- Filter comments containing words you block, using the Page's keyword moderation settings.
- Hide or delete individual comments manually on any post or ad.
- Ban or restrict people who repeatedly break your rules.
- In groups, turn off commenting on an individual post entirely.
The exact menus move around between the Facebook app, Page settings, and Meta Business Suite, so as of this writing the reliable approach is to open the post's audience or comment controls directly, or search the Page settings for moderation options rather than memorizing a path.
Limiting the comment audience
On public posts, Facebook lets the author restrict the comment audience. Setting it to profiles and Pages you mention effectively silences comments from everyone else, which is the closest a Page gets to turning comments off on a normal post. The trade-off: it silences your fans and buyers too.
What turning comments off costs you
- Comments are an engagement signal; removing them entirely tends to suppress distribution.
- Buyers cannot ask the pre-purchase questions that other buyers read.
- Objections do not disappear — they move somewhere you cannot answer them.
- Comments on ads cannot be turned off at all, so paid campaigns still need moderation.
The alternative: keep comments on, hide the bad ones
Most teams that want comments 'off' actually want the spam, abuse, and pile-ons gone. Hiding does that without killing the conversation: a hidden comment stays visible to its author, so arguments rarely escalate, and everyone else sees a clean thread. At scale that means auto-hide rules for links, contact details, profanity, and negativity, plus an optional hide-everything mode where new comments wait for approval during sensitive launches.
When switching comments off is right
There are legitimate cases: memorial posts, active legal situations, or announcements where any discussion invites harm. For those, limit the comment audience on the post and monitor what still lands. For everything else, a hide-first moderation posture keeps the reach and loses the noise.
