Ever wish you could run ads directly to members of a Facebook group? Here’s the deal-you actually can. The quick answer: Post your video on your Facebook business page, share it into the group, and then retarget everyone who watched it. Boom-you’re advertising to group members without needing their emails.

Why This Works

Facebook doesn’t let you directly target people just because they’re in a group. But here’s the loophole:

When you share your business page post into a group, members who watch that video get tracked by Meta.
That watch data creates a custom audience you can retarget with ads.
You now have a way to stay in front of a very specific audience-without needing their contact info.

This is one of the most creative ways to reach niche communities on Facebook while staying compliant.

Step 1: Post Your Video on Your Facebook Business Page

Start by publishing the video you want to use on your Facebook business page (not your personal profile).

Why? Because you’ll need that content tied to your business page so Meta Ads Manager can track engagement and views.

Pro tip: Keep your video short, engaging, and valuable. Think educational tips, market updates, or client stories that resonate with your group’s audience.

Step 2: Share the Video Into the Facebook Group

Next, click share and post that same video into the group.

⚠️ Important:

Follow the group’s rules-some don’t allow self-promotion.
Frame your video as valuable content, not a sales pitch.
Encourage conversation in the comments to boost engagement.

The more members who watch it, the larger your retargeting audience will be.

Step 3: Build a Retargeting Audience

Now head over to Meta Business Suite (Ads Manager) and set up a custom audience:

Go to Audiences → Create Audience → Custom Audience.
Choose Video Views as the source.
Select the video you posted on your business page.
Decide how much of the video they need to watch (3 seconds, 15 seconds, 25%, etc.).
Save your audience.

That’s it-you now have a warm audience of Facebook group members who engaged with your content.

Step 4: Run Your Retargeting Ad

Now create a retargeting ad campaign using that custom audience. Ideas for realtors:

Share a free buyer or seller guide.
Promote your next open house.
Invite them to your educational webinar or local event.
Highlight a new listing.

Since these people already watched your content, they’re more likely to click and engage.

Why Realtors Should Use This Hack

This strategy is a goldmine for real estate professionals because:

Groups = niche communities. First-time buyers, investors, neighborhood associations-whatever your focus is, there’s a group for it.
Zero email list required. You don’t need contact info to stay in front of them.
High trust factor. You’re showing up inside a community where people already feel connected.
Low-cost leads. Retargeting audiences are cheaper than running broad ads.

Example in Action

Let’s say you’re in a local neighborhood Facebook group. You share a video on “Top 3 Things to Know Before Selling Your Home in [Neighborhood].”

Group members watch it. Then, you retarget them with an ad offering your free seller’s guide or inviting them to a neighborhood open house.

Instead of cold outreach, you’re staying in front of people who are already interested.
