What Publer Can't Do on Facebook: Groups, Extraction & Viral Research

Publer is a great-value creation-and-scheduling tool — this isn't a hit piece. But there's a wide gap between "cheaply designs and schedules your Facebook Page posts" and "grows your Facebook," and that gap is a specific list of things Publer structurally cannot do. If you're evaluating whether Publer covers your Facebook growth needs, this is the honest checklist: every major growth capability, whether Publer can do it, and what fills the gaps. We build FaceBot, so factor that in — but the "can't" items aren't opinions, they're consequences of Publer publishing through Meta's API instead of acting as a real user. A rich, cheap feature set and Facebook growth capability are different things.

Quick Comparison at a Glance#

Notice the pattern: everything Publer can't do is a group or organic-reach capability; what it excels at is affordably creating and scheduling Page content. That's the API boundary — no feature count changes it.

Why the Gap Exists#

Publer connects to Facebook through Meta's Graph API via a developer app. The API decides what any connected tool may do — on Facebook, it permits Page publishing and reading your own analytics, but little else for third parties. Critically, Meta closed third-party Group posting through the API in 2024. So the gap isn't Publer being under-built or too cheap; it's Publer (correctly) staying inside the API's walls. FaceBot operates outside those walls by acting through your real browser session — the same actions you'd take by hand — which is why it can do the "can't" list.

The Facebook Growth Capabilities Publer Lacks#

1. Posting to Facebook groups#

The big one. Groups are where free organic reach lives, and Publer can't post to them. FaceBot's Group Auto Poster posts across many groups from your session — see the group posting guide. If a tool can't reach groups, it can't drive organic Facebook growth, full stop.

2. Discovering relevant groups#

You can't grow in groups you haven't found. Publer has no group discovery. FaceBot's Bulk Group Finder surfaces relevant groups by keyword so you build a target list of hundreds.

3. Joining groups at scale#

Building a reach network means joining many groups safely. Publer offers nothing here; FaceBot's Auto Group Joiner handles it at a paced, human-like rate.

4. Audience research and extraction#

Publer helps you create content but can't research the audiences you're trying to reach. FaceBot's Group Members Extractor supports audience research from public signals — for understanding a niche, not harvesting private contacts (which isn't possible anyway).

5. Viral content research#

To know what to post, study what works. Publer can't see into the groups you're targeting. FaceBot's Group Viral Finder surfaces the top-performing posts in any group so you model the winning format.

6. Commenting across groups#

Engagement drives reach and familiarity. Publer can't run genuine commenting activity across groups; a real-browser tool can, as part of an organic presence.

7. Claiming and managing owned groups#

Owning a group is a durable audience asset. Publer has no group-admin tooling. FaceBot includes tools to claim admin-less groups and moderate groups you run — a growth surface entirely outside Publer's scope.

8. Acting as a real user#

Underlying all of it: Publer is a developer app; FaceBot acts as you. That architectural difference is why one is confined to Pages and the other reaches the whole organic surface.

What Publer Does Well (Being Fair)#

To keep this honest, Publer genuinely beats FaceBot at what it's for: an affordable built-in design editor, watermarks, bulk upload, analytics, a generous free tier, and easy multi-network scheduling — a lot of value for a low price. If your priority is creating and scheduling content affordably, Publer is excellent and FaceBot isn't trying to replace it. The capability gap runs both ways — it just happens that everything Facebook-growth-specific lands on FaceBot's side.

How the Gap Plays Out: Great Content, No Audience#

Picture a creator who loves Publer: they design a month of polished, on-brand posts in the built-in editor and schedule them across their Pages — and each reaches ~3% of a few thousand followers, so the beautiful content is seen by almost no one and the audience stays flat. Now the same creator adds FaceBot: they find 200 relevant groups with Bulk Group Finder, join them, research what performs with Group Viral Finder, and post that same polished content across them with Group Auto Poster — reaching tens of thousands of new engaged members and gaining real followers. Same content, opposite outcome, because one workflow could reach groups and the other structurally couldn't. That's the capability gap made concrete: Publer makes the content; only a group-capable tool gives it an audience.

Can Publer Add These Features Later?#

No — and understanding why saves you planning around a future that won't arrive. These capabilities live outside Meta's API, and Publer is an API-based creation/scheduling tool by design. Meta closed third-party Group posting via the API in 2024 and shows no sign of reopening it; group discovery, joining, and cross-group research were never third-party API features. For Publer to do the "can't" list, it would have to stop being an API tool and become a real-browser automation tool — a completely different, heavier product. So the gap is permanent, not a pending update. Plan around what each tool actually is.

Which Should You Choose?#

• Need the group-growth loop (discovery, joining, posting, research)? → FaceBot; Publer can't do any of it.
• Need affordable content creation and scheduling? → Publer.
• Need both? → Publer to create, FaceBot for the reach that gives your content an audience.

Our Verdict#

Publer is excellent at affordably creating and scheduling content, and unable to grow a Facebook audience — not through any fault, but because the API confines it to Pages while growth lives in groups. If your checklist includes posting to groups, finding and joining them, researching audiences, or surfacing viral content, Publer checks none of those boxes and FaceBot checks all of them. Match the tool to the list — and since both are cheap, using Publer to create while adding FaceBot for growth is an easy, low-cost setup.

Frequently Asked Questions#

1. Can Publer post to Facebook groups?#

No. Meta restricted third-party Group posting through the API in 2024, so Publer is limited to Facebook Pages. FaceBot posts to groups because it acts as you in your own browser rather than through a developer API.

2. Can Publer extract Facebook group members or UIDs?#

No — API-based tools like Publer don't offer audience extraction. FaceBot's Group Members Extractor supports audience research from public signals (for understanding a niche, not harvesting private contacts, which Facebook doesn't expose to anyone).

3. Does Publer have a viral content finder for Facebook?#

No. Publer helps you create and schedule your own content but can't research top-performing posts inside the groups you're targeting. FaceBot's Group Viral Finder does exactly that so you model what works.

4. Can Publer help me find and join Facebook groups?#

No — it creates and schedules content for accounts you connect; it has no group discovery or joining. FaceBot's Bulk Group Finder and Auto Group Joiner build your group network, the foundation of group reach.

5. What can FaceBot do that Publer can't?#

Post to groups, discover and auto-join them, extract audience data for research, find viral group content, comment across groups, and claim/manage owned groups — plus act as a real user rather than a developer app. All outside Publer's API scope.

6. What does Publer do better than FaceBot?#

An affordable built-in design editor, watermarks, bulk upload, analytics, a generous free tier, and multi-network scheduling. For affordably creating and scheduling content, Publer is excellent and stronger.

7. Why can't Publer just add group posting?#

Because it publishes through Meta's Graph API, and Meta closed third-party Group posting via the API in 2024. It's not a feature Publer can toggle on — the capability requires acting as a real user, a different architecture than a creation/scheduling tool.

8. Do I need both Publer and FaceBot?#

If you want affordable content creation and Facebook growth, yes — Publer to create and schedule, FaceBot for the group-growth capabilities Publer lacks. Both are cheap enough that pairing them is easy.

Conclusion#

The line between Publer and FaceBot is the line between what Meta's API allows and what a real user can do. Publer affordably creates and schedules Page content; it cannot post to groups, find or join them, research audiences, or surface viral content — the entire toolkit of organic Facebook growth. If those capabilities are on your list, only a real-browser tool checks them — and since both tools are cheap, using Publer to create while adding FaceBot for growth covers everything.
