Dynamic Keyword Insertion (DKI) must follow Google Ads character limits:
Character Limits for Ad Components with DKI:
✅ Headline 1, 2, 3: 30 characters max
✅ Description 1 & 2: 90 characters max
✅ Path Fields (Display URL): 15 characters per path
How DKI Affects Character Limits:
If the dynamically inserted keyword exceeds the character limit, Google will default to the fallback text (e.g., {KeyWord:Shoes}).
The longest keyword in the ad group should fit within the limits to prevent truncation.
