Numbers matter when they change a decision
Impressions, clicks, visits, enquiries, conversions and costs are signals, not conclusions. Nexus connects the available signals to the objective the company is pursuing.
Sources that add evidence, not dependencies
Search Console may add search data; Matomo, site behaviour; ad platforms, campaign outcomes; Ahrefs or Semrush, external context. If a source is not connected, Nexus does not invent it.
From report to next experiment
A decline may require investigation before any change. Growth may justify a follow-up experiment. Nexus should propose the most useful check rather than react automatically to every variation.
