Manage a Google Ads campaign or ad group's targeting AFTER creation: GEO, LANGUAGE and AUDIENCES. op 'add' at campaign level (default): up to 100 locations (negative: true = exclude) and/or 50 languages, OR up to 50 audiences (audiences cannot combine with geo/languages in one call — separate calls). op 'add' at ad-group level (level: 'ad_group' + ad_group_id): audiences only. AUDIENCES: pass user_list_id items (audience segments from adsap_google_list_audiences) — campaign-level TARGETING works on Search/Shopping only; campaign-level EXCLUSION (negative: true) also on Display/Performance Max; ad-group level (target or exclude) on Search/Display/Shopping. DEMAND GEN is different: pass audience_id items (Audience resources) on the AD GROUP — nothing at campaign level. Video supports no audience edits. The same user list cannot be attached at BOTH campaign and ad-group level. 'mode' ('targeting' = narrow delivery to the audiences | 'observation' = full reach, bid adjustments only) sets the audience targeting setting — combinable with the audience add or standalone; Google's default with NO mode set is TARGETING, so pass mode: 'observation' for Search/Shopping unless the user explicitly wants to narrow reach. op 'remove': remove ONE criterion by composite id "<parent_id>:<criterion_id>" (level 'campaign' → campaign criterion, 'ad_group' → ad-group criterion). Geo/language criterion ids EQUAL their constant ids (France on campaign 123 = "123:2250"); AUDIENCE criterion ids are Google-internal — capture them from the add response (created_criteria[].entity_id). Criteria are immutable: to change one, remove it and add the replacement. Always dry_run: true first. For campaign negative KEYWORDS use adsap_google_manage_keywords op 'add_negative'.
