Ginny Marvin, the Google’s Ads product liaison officer, said:“There’s been some confusion about brand safety controls and reporting supported in PMax. Inventory type – expanded, standard, limited – allows you to quickly choose the type of content best suited to your brand on YouTube & GDN. – Content type exclusions prevent ads from showing on certain areas of video content such as live streaming or embedded YouTube video. Sensitive content categories allow you to exclude certain types of GDN content such as tragedy and conflict. – Exclude up to 1000 content keywords to prevent ads from showing on YouTube & GDN content related to those exact words.
