Google Ads
- Ads began appearing inside Google AI Mode responses in the US

- YouTube channels to be auto-linked to Google Ads accounts after 30-day notice on high-confidence matches
A new help page says Google will automatically link a YouTube channel to a Google Ads account when its systems detect a high-confidence connection. Channel owners and Ads admins get 30 days' email notice to opt out; otherwise the link is created and can be removed at any time. Source
- Performance Max gained an 'Upload' tab to add video files directly, stored in a Google-managed house channel
Advertisers can upload video files inside the PMax Edit assets panel without a linked YouTube channel or Shared Library. Videos are hosted on a Google-managed house channel, so they get no YouTube Analytics, remarketing lists, metadata editing, custom thumbnails or appeals. Source
