If your campaign is not scaling sufficiently, it is recommended to review your line item's targeting parameters to ensure they are not overly restrictive. To identify this, follow the following steps:
- Select your campaign from the campaign list home page 
- Click to Edit Campaign 
- Select the line item > click on the Targeting tile > click on Daily at the top right which will reveal Daily Reach and Daily Ad Opportunities - For definition of Reach and Ad opportunities, see here. 
 
- Insufficient daily ad opportunities due to targeting limitations trigger a caution sign, indicating limited scale and potential delivery challenges for your line item. 
- Check your targeting to ensure it is not too restrictive: - Audience - Geotargeting: avoid zip code & city targeting if possible. 
 
- Inventory - Contextual & Behavioral Targeting: Recommended to apply Contextual and Behavioral targeting on separate line items to minimize scale issues. 
- Brand Safety: Apply the Standard brand safety level to cover basic needs without overly restricting delivery. 
- Site Lists: Ensure a minimum of 100 websites in your site list for sufficient inventory to deliver your campaign. 
- Website Tier: Apply either Select or Reach tier targeting for a balanced mix of premium inventory and scale to meet your campaign needs. 
- Website Category: Optimize daily ad opportunities by using Teads Contextual targeting, which targets relevant articles instead of entire sites, based on the content taxonomy provided by IAB. 
 
- Device: To maximize scale, it is recommended to run campaigns on cross-device and/or mobile platforms. Excluding mobile devices from your line item will significantly limit the available inventory, as approximately 80% of our inventory is mobile. 
- Operating systems & Browsers: Targeting specific operating systems and/or browsers, such as Google Chrome or macOS, can significantly limit scale. It is advisable to use this targeting only for performance optimization purposes.
