What’s new
- Share of Voice metrics: Impression share, click share, and losses due to budget or rank (Search & Shopping only)
- Asset group–level URL options: Add tracking templates and custom parameters at the asset group level
- Search themes limit increased: Up to 50 search themes per campaign
- Improved asset group imports: Eligible assets now import even if some images fail requirements
