hostAge-Sandbox
New domains and new hosts initially receive less trust credit from Google — not because they are penalized, but because there is no behavioral history yet from which Google could draw conclusions.
What it measures
New domains and new hosts initially receive less trust credit from Google — not because they are penalized, but because there is no behavioral history yet from which Google could draw conclusions. This 'sandbox effect' describes passive damping, not an active penalty. As the host ages and builds a positive usage history, the damping fades.
Derived from
The age of the host (hostAge) — how long the domain or host has been known and active.
Metric detail
hostAge = age of the host; young hosts receive less trust credit — passive damping, not an active deduction. [B field, C sandbox effect]
Why this attribution
Only Trust (indirect) — the missing trust credit is the only E-E-A-T connection. No bearing on Expertise, Experience or Authority.
Strategic consequence
Domain migrations or new sub-domain launches must account for an initial ramp-up period. Strategically: set up new domains early to start the clock — even if the full content launch follows later. Patience is the only strategy.
