A useful standard
What every story should make clear
SearchEngineAnswer is an independent publication. Stories should help a reader understand what changed, what the evidence supports, and what to do next.
The reader job is explicit
A story should answer a focused question or support a concrete decision rather than merely announce a topic.
Sources remain inspectable
Material facts stay close to current primary documentation, reproducible evidence, or clearly attributed reporting.
Updates retain context
Meaningful changes, uncertainty, corrections, and publication dates remain visible so readers can judge freshness.
