Losing reach — reach down from Day 0. Distribution problem. Fix hooks and cadence first.
Plateau — reach flat. The format has stopped surprising the algorithm. Change the format, not the frequency.
Reaching, not converting — reach climbing, followers flat. Content lands, the profile doesn't close. Fix bio, pinned posts and CTAs.
Building — reach up steadily. On track. Keep the calendar and keep testing formats.
Progressive overload — interactions growing faster than reach. The audience is acting, not just watching. This is the one you scale.
