"The algorithm changed" gets blamed for a lot of flopped posts, but most of what currently drives (or kills) reach on Facebook is fairly consistent and well documented — it's just not a single switch. Here's what's actually shaping distribution right now, and where PostPix's tools line up with it.
Where this lines up with PostPix: the Carousel Post Generator plays directly into the feed-depth signal — a well-built carousel gives people a reason to keep swiping, which is exactly the kind of engagement currently rewarded. The Policy Checker catches engagement-bait phrasing before you publish. And Why Did This Post Fail? diagnoses the hook and curiosity factors that decide whether someone engages at all in the first two seconds.
A caution on specifics: exact thresholds and weightings (how many words a comment needs, precise retention percentages) aren't something Meta publishes in detail, and figures circulating online for these are often unverified. Treat the directional signals above — what clearly helps, what clearly hurts — as the reliable part, and be skeptical of anyone quoting precise internal numbers.
None of this rewards gaming the system — it rewards posts people genuinely stop for. That's the same goal PostPix's tools are built around: a stronger hook, a cleaner caption, and a format that holds attention.
Build a post designed to hold attention.
