Inbound-link authority cohort

Four source pages are equivalent. Every source links to the same shared target and to one unique control.

The shared page accumulates four independent internal inlinks; each control receives only one. Fetch timing and repetition can therefore be compared without changing target depth.

• Authority source 1One shared and one unique outbound target.
• Authority source 2One shared and one unique outbound target.
• Authority source 3One shared and one unique outbound target.
• Authority source 4One shared and one unique outbound target.
