Source performance is broader than traffic or mention count.
The important question is not whether a source is active. It is whether the source is still producing credible, timely, high-yield evidence for your market.
Freshness
Watch recency, posting cadence, content availability, and policy changes so dead sources do not keep passing as live sources.
Coverage gaps
Identify where expected market motion is missing so the team can investigate whether the blind spot is real or the source stack is incomplete.
Phrase performance
See which themes, pains, and comparison terms are actually correlated with useful opportunities instead of generic chatter.
Weak source discipline destroys confidence slowly.
Teams usually notice the problem too late: lower queue quality, weaker stage inference, and more time spent manually checking whether the system is still telling the truth.
Kill dead weight
Retire stale channels before they waste analyst effort, inflate confidence, and crowd out sources that still carry real market pressure.
Tune the stack weekly
Source review becomes part of the operating rhythm, not an emergency cleanup after everyone notices the queue has gone soft.
Protect system trust
Operators keep using the output because the team can defend how the inputs are monitored, challenged, and improved.
The system gets sharper every review cycle.
Source Health closes the loop between market observation and system maintenance so the quality of account intelligence compounds instead of degrading over time.
Rebalanced source mix
Effort and attention move toward live, high-yield sources and away from channels that keep creating false urgency.
Early decay alerts
When a source begins to underperform or a key phrase family stops yielding, the team sees the change before it becomes expensive.
Defensible reporting
Leaders can see not just what the system found, but how healthy the source network is behind those findings.
A signal engine without source health will eventually lie to you.
Monitor the inputs with the same rigor you apply to the opportunities, and the system stays credible as your market evolves.
