Advertise in Facebook Groups
Facebook ads cannot run inside groups. The only way into a group’s feed is a sponsored post arranged with its admin. Harbor makes that a marketplace: 5,600+ vetted Facebook Groups and Pages, verified admins, negotiated placements, and payment held securely with Stripe, our payment partner, until the post is live and approved.
Why groups beat the feed
A group is an audience that chose to be there. A 40,000-member private parenting group is not 40,000 impressions; it is a room with rules, a moderator members trust, and product conversations happening daily. A recommendation posted by the admin lands as advice, not advertising.
How it works on Harbor
Search by audience, not by page name. Harbor returns groups with honest numbers: real member counts, engagement where measured, and a starting rate. Agree terms in the Deal Room, fund the deal, and the admin posts to their own group. Proof, approval, release.
What a placement looks like
A pinned post, an announcement, a review thread, a launch giveaway. Formats are agreed per deal; the admin always controls what runs in their group.

Direct answers
Can brands advertise inside Facebook Groups?
Not with ads. Facebook's ad system does not place ads inside groups. The way in is a sponsored post arranged with the group's admin. Harbor is the marketplace for exactly that: it lists vetted groups, verifies the admin, and holds payment until the post is delivered and approved.
How much does it cost to sponsor a community post?
Rates are set by each community's admin, shown as "from $X" on listings, and negotiated in the Deal Room. The brand pays a 5% fee on top of the agreed price, with the exact figures shown to both sides before anyone commits.
How do I know a community is real?
Harbor checks. Ownership Verified means the person genuinely controls the community. Audience Verified means a Harbor review confirmed the audience. A count is marked (verified) only where Harbor has confirmed it, and a badge renders only when its underlying check is true.
