Slop”），程序化广告中还混入用于欺诈的机器人流量。DoubleVerify拉美区域副总裁Armando Rodriguez表示，数字生态越复杂，媒体质量对保障每次曝光产生价值、保护投资和维护品牌信任就越关键。\n\n在巴西，已认识到验证工具重要性的品牌发现，复杂无效流量（SIVT）违规率下降了57%。但拉丁美洲在品牌适宜性方面表现低于预期，违规率达6.9%，高于全球基准；未受保护的广告系列出现在不当内容旁的概率约为使用安全工具者的三倍。\n\n报告称，巴西营销人员清楚问题规模：39%表示经过验证的品牌适宜性控制能让他们在AI平台投放时更有安全感，41%重视广告展示位置的透明报告。更先进的广告主正转向从 campaign 初期就纳入媒体质量的模式，整合竞价前控制、持续测量和优化。DoubleVerify企业销售高级总监Gustavo Dallaqua表示，巴西正处于关键成熟阶段，品牌日益认识到AI可提升效率，但需配套控制和测量。\n\n报告还提到一个全球饮料品牌案例：该品牌使用DV Authentic Brand Suitability解决方案进行竞价前评估，实现133%的投资回报率，随后在所有数字媒体采购中采用该方案。DoubleVerify企业销售总监Sue Ellen Durães表示，使用媒体质量保护机制的广告系列在多项指标上表现明显更好，目标不仅是避开特定内容，更是让营销人员更好地控制投资去向。","why_it_matters":null,"cbi_observation":null,"direction_tag":"巴西","primary_category":"科技平台","secondary_topics":["科技","行业趋势"],"content_level":"编辑整理","event_type":"行业报告","audience_tags":[],"event_location":null,"verification_status":"unverified","published_at":"2026-11-02T11:01:03.484Z","display_date":"2026-11-02","source_published_at":null,"source_url":"https://www.meioemensagem.com.br/patrocinado/doubleverify/o-impacto-da-ia-nos-investimentos-de-midia-no-brasil-e-no-mundo","source_name":"Meio
