AD STRENGTH & CREATIVE STUDY: DATA & LEARNINGS FROM 1M+ ADS
This study of over 1 million Google Ads looks at the correlation between Ad Strength and performance, the impact of pinning, and the importance of text formatting. Ads tend to perform best with ‘average' Ad Strength, suggesting it's not something worth optimizing for. Responsive Search Ads and Demand Gen ads both have 40%+ better ROAS when using sentence case text instead of title case. Pinning assets has a negligible impact, while maxing out ad copy character counts tends to hurt performance.
