Diagnose before reacting
A drop in reach can come from several different causes: a decline in content quality or consistency, a broader algorithm update affecting many accounts, or an account-specific issue like a policy violation. Each calls for a different response. Reacting with a broad strategy change before identifying the cause risks fixing the wrong problem.
Check whether the drop is account-specific or broader
Comparing notes with other accounts in a similar niche, or checking whether the drop coincides with a widely reported algorithm update, helps distinguish a platform-wide shift from a problem specific to this one account. The two call for different fixes.
Rule out an account-health issue specifically
A sudden, sharp, sustained reach drop is a different animal from a gradual decline. Check it against the platform's own account status and any recent guideline warnings. An account-level issue is a distinct problem from a content-strategy one, and it needs a different fix entirely.
Give any fix real time before judging it
A single post, or even a single week, is not enough evidence to judge whether an adjustment worked. Reach is noisy. Confirming a real recovery in the trend takes a few weeks of consistent posting.
