About AI Facebook Ads & Bulk Group Poster - Serious Poster

Serious Poster publishes to the Facebook groups you already belong to, from one saved campaign, the way a person would. Spaced out, worded differently every time, and never twelve groups in ninety seconds. Free for 500 posts a month, no card required. If you promote anything in groups, you already know both ways this goes wrong. Do it by hand and it eats your week. Twenty groups is twenty tabs, twenty pastes, twenty re-uploads of the same three photos, and by group eleven you are pasting the identical caption because you stopped caring somewhere around group six. Do it with a traditional bulk tool and something worse happens. The same text lands in twenty communities inside two minutes, always at the same interval, always with the link in the body. Admins see it. Members report it. Facebook notices the pattern long before a human does, and the reach on every one of those posts quietly goes to nothing. You are still posting. Nobody is still reading. This exists for the second problem. It is an automated tool whose entire design goal is to not behave like one. WHAT IT ACTUALLY DOES Publishes to as many communities as you want from one saved campaign Randomizes the gap between each send, so the interval never forms a pattern Rewrites the text every time using spintax, so no two are identical Puts your link in the first comment instead of the body, which is the single biggest thing you can do for reach Rotates through media sets so the same photo does not follow you everywhere Types the text out character by character in the real composer Waits on the page before starting, and scrolls the feed while it waits Works in bursts with long breaks, the way a person picks up their phone a few times a day Sleeps outside your active hours, because nobody posts 47 times at 4am Never touches the same group twice inside a cooldown window you set Stops the entire run the moment a block, checkpoint, or rate warning appears PUT THE LINK IN THE FIRST COMMENT If you take one idea from this listing, take this one. A link in the body suppresses reach almost everywhere. Facebook would rather keep people on its platform, and admins have been trained by years of spam to remove anything with an outbound URL in it. You are competing at a disadvantage before anyone reads a word. Serious Poster publishes the body clean, waits a randomized 45 to 120 seconds, then drops the link as the first comment underneath. Same link. Same audience. None of the penalty. This one setting is routinely worth more than everything else in the extension combined. It is on by default. PACING YOU CAN SEE AND CHANGE Every timing control has a real number behind it, and the editor tells you why the default is what it is. Nothing is a black box marked "safe mode." Delay between sends. Randomized between a floor and a ceiling you set, defaulting to 3 to 8 minutes. A fixed interval is a fingerprint. A range is not. Dwell before composing. 8 to 25 seconds on the page before the composer is touched. Arriving and submitting in the same second is the clearest bot tell there is. Scroll while dwelling. Costs nothing, and produces the scroll and viewport events a real visit produces. Human typing. Character by character at a words-per-minute you choose, defaulting to 55. Text that materializes all at once never generated a keystroke. Typing produces the events the composer is actually built to receive. There is a paste mode if you would rather have the speed. Session bursts. Five sends, then a 20 to 60 minute break. People do a few and put the phone down. They do not work a queue for four straight hours. Active hours. 8am to 10pm local by default. Outside the window the runner simply waits. Cooldown. 24 hours by default. Even if a group sits in two campaigns, it will not get hit twice. Shuffle. The order changes every run, so your sequence is not itself a signature. Warmup mode. For a new or recently restricted account, ramps the daily cap up gradually instead of going to full volume on day one. A brand new account behaving like an established one is how accounts get limited. Stop on warning. On by default, and the most important safety setting in the list. The run halts on the first block, checkpoint, or rate notice. Pushing through a warning is how a temporary limit becomes a permanent one. SPINTAX, SO NO TWO ARE ALIKE Write it once. Get hundreds. {Hey|Hi|Morning} everyone, {just wanted to share|thought I would post} something. Every send gets a different roll. Nest it as deep as you like, use an empty option like {great||fantastic} to mean "sometimes nothing at all," and escape a literal brace with a backslash when you need one. The editor previews real variants as you type, counts how many distinct versions your text can produce, and flags syntax errors before you ever start a run. Same engine for bodies and first comments. MEDIA SETS Upload your photos once and gather them into sets. A campaign draws a randomized number of attachments from the sets you pick, so the same image is not stapled to everything you send this month. Media is uploaded from the dashboard and handed to the composer at run time as a real file attachment, exactly as if you had dragged it in yourself. THE AI SIDE (OPTIONAL) The writer and the spinner are free and unmetered on any signed-in account: describe what you are promoting, or paste something you already like, and get it back with spintax woven in. It kills the blank page. It is not a replacement for knowing your audience, so edit everything it hands you. The paid studio goes further. It researches your market and returns named audience segments, writes the ad copy and the first comment for each, and renders an image with the exact words the copy asked for. It is metered because it costs real money per generation, and plenty of people never need it. IT RUNS AS YOU, NOT AS AN APP Serious Poster drives the browser tab you are already logged into. That decision has consequences worth understan…
