Advertising policy
No advertising network is active at this time. Reserved ad placements stay entirely dormant and invisible unless and until an advertising network is actually enabled — they never show a placeholder box to ordinary visitors — and are only made visible internally, on demand, to review real layout positions before any network is wired in.
When advertising is enabled, ad placements will always be visually distinguished from editorial content, and will never influence which colours a similarity, comparison or suitability ranking surfaces.
