Yes, this is a common issue with Google Ad Grant accounts. Since Ad Grants are limited to non-paid, low-competition ad placements, your ads will often receive few or no impressions if your keywords are highly competitive and dominated by paying advertisers.
The $2 max CPC cap (unless using Maximize Conversions) and strict eligibility rules make it difficult for grant ads to compete in crowded spaces. To improve delivery, try switching to Maximize Conversions bidding (with proper conversion tracking in place), focus on long-tail, mission-relevant keywords, and ensure your ads and landing pages are tightly aligned to boost Quality Score.
Unfortunately, direct support is limited for Ad Grants, so the community forum is typically your best resource unless you're working with a Google-certified nonprofit partner.
