Chrome extension for Facebook groupsPost to every Facebook group.
Post to every Facebook group.
Sound like a person in each one.
A bulk Facebook group poster built around reach rather than speed. One template goes in. Different wording, a different photo and a different rhythm come out for every group you belong to, so your posts keep getting shown.

Why this matters
Facebook rarely deletes bulk posts. It stops showing them.
Meta describes its own approach as remove, reduce, inform. Content that breaks a rule gets removed. Everything that merely looks like spam gets reduced: the post stays on your profile, it stays in the group, it looks completely normal to you, and it is shown to a fraction of the people it would otherwise reach. Nothing tells you it happened, which is why people call it a shadowban.
That is the whole problem with bulk posting. Hitting forty groups is worthless if thirty-five of those posts are throttled on arrival. Every setting in Serious Poster exists to keep you out of that bucket, and the full guide to Facebook shadowbans covers how to tell whether you are already in it.
The same text in every group
Near-identical copy across many groups is the cheapest possible thing to detect, and the most common reason a campaign quietly stops being shown.
Spintax plus a pool of separate posts, so no two groups get the same wording.
Posting faster than a person could
Twelve groups in four minutes is not a rhythm a human hand produces. A fixed interval between posts is even easier to spot than a fast one.
Randomised gaps, bursts with long breaks, and posting hours you set.
An outbound link in the post body
Posts that send people off Facebook are consistently shown to fewer of a group than posts that keep them on it.
The post goes up clean and the link follows as the first comment.
The same photo attached every time
Images are fingerprinted. Forty posts carrying one identical file group themselves together whether or not the text varies.
Media sets, with each post drawing its own attachment at random.
Arriving and posting instantly
A real visit scrolls, pauses and produces keystrokes. A page that loads and submits a finished post in the same second did not have a person behind it.
Dwell time, feed scrolling, and text typed character by character.
Members hiding or reporting you
Negative feedback is weighted heavily, and hitting the same group over and over is the fastest way to earn it.
A per-group cooldown and daily caps, so you are never the person flooding a feed.
None of this is a guarantee, and anyone selling you one is lying. It is the removal of the specific things that are known to cost you reach.
One plate, every colour
Write a post once and mark the parts that should vary. Every send picks its own combination, so no two groups get the same wording. How to write spintax that reads like a person.

Hey everyone, just listed a clean 2 bed in Riverside. DM me if you want details.
Three steps, then it runs itself
- 1
Install the extension
It posts through the Facebook session you are already signed in to. No password, no API key, nothing to get approved.
- 2
Build a template
Post texts, first comments, media sets, your groups, and how carefully it should pace itself. Save it once and reuse it.
- 3
Press start, walk away
Close the popup. It keeps running in the background, survives a browser restart, and tells you when it is finished.
The one that matters most
Your link goes in the first comment
A link in the body of a group post sends people off Facebook, and posts that do that are shown to fewer of the group. Serious Poster puts the post up clean, waits a randomised minute or two, then leaves the link as the first comment underneath. On its own this usually does more for you than every other setting combined.
Media sets
Drop photos and video into sets. Each post draws its own attachment, so a campaign never ships forty copies of the same image.
Human pacing
Dwells on the page, scrolls the feed, types character by character, then waits a randomised few minutes. No fixed interval anywhere in the run.
Templates that stick
Everything saves together, including your timing settings. Load it next week and it is exactly how you left it.
It stops when told
The moment a block, checkpoint or rate warning appears, the run halts and says so. Pushing through a warning is how a one-day limit becomes permanent.

Straight answers
Will this get my Facebook account banned?
Nothing can promise that, and anyone who does is selling you something. What it does is remove the patterns that get reach reduced: identical text, fixed intervals, instant posting, links in the post body, and running through the night. Start slow, use warmup on a new account, and leave the safety stop on.
Do you need my Facebook password?
No. It works inside the browser you are already signed in to. We never see your credentials and there is nothing to enter.
How would I know if my reach is already reduced?
Usually you cannot know directly, and that is rather the point of it. The tell is a post that looks completely normal on your own screen while getting a fraction of the views, reactions or replies that the same kind of post used to get in that group.
What if Facebook changes their layout?
The extension carries fallback selectors and we ship updates through the Web Store. If posting does break, it stops and tells you rather than quietly doing nothing.
Can I run more than one Facebook account?
Yes. It follows whichever Facebook account that browser profile is signed in to, so use a separate Chrome profile per account.
How many Facebook groups can I post to at once?
As many as you belong to, though the useful answer is fewer than that. The tool paces a run across hours rather than minutes, holds a cooldown per group and respects a daily cap you set, because thirty groups at full reach beats sixty groups at a fifth of it.
