Ad reach counts distinct people or system-distinguished users exposed to advertising during a defined period. Google may use statistical models to account for the same person across devices.[1] Reach differs from impressions: repeat exposure does not create another newly reached person.
State the platform, period and identity basis. Do not simply add channel reach because audiences overlap. Reaching prospective new buyers also serves a different purpose from repeating a message to interested visitors. Reach alone establishes neither attention, purchase intent nor incremental sales.
