"The algorithm just isn't showing my posts anymore" is the most common explanation creators give for a post that flopped — and it's almost always wrong, or at least incomplete. Most underperforming posts fail for one specific, fixable reason: a weak hook, a thumbnail that doesn't read at a glance, or a caption that doesn't earn the next sentence. The problem is actually diagnosing which one it was, instead of guessing.
A post can be weak in just one of these and still underperform badly — which is exactly why a generic "write a better caption" fix often doesn't help. You need to know which one actually broke.
Open Why Did This Post Fail? and upload the real image or thumbnail — not a redesigned version. The diagnosis depends on seeing exactly what your audience actually scrolled past.
Include the emojis, hashtags, and line breaks exactly as they appeared — small wording choices matter to the diagnosis.
This step is optional but changes the diagnosis meaningfully — "nobody saw it" (low reach) and "people saw it and scrolled past" (reach but no engagement) point to completely different fixes, and the AI can only tell them apart if you share the numbers.
You'll get a score across all five factors, plus one clear sentence naming the single biggest problem — not a generic checklist of everything that could theoretically be better.
You'll get a refined hook, caption, and image prompt built specifically to fix the diagnosed problem — click "Open in Image Post Generator" to carry the new hook straight into a fresh post.
Treat the diagnosis as a strong starting point, not gospel. The AI is reading the post the way a person mid-scroll would, which is genuinely useful — but it doesn't have access to your page's specific audience, posting history, or Facebook's internal distribution signals. Use it to catch the obvious, fixable problem, then apply your own judgment about your specific audience on top of it.
Run this on a handful of your underperforming posts and a pattern usually shows up fast — most creators find the same one or two factors keep coming up as the real bottleneck, which tells you exactly what to fix across every future post, not just the one you just analyzed.
Stop guessing why a post flopped.
