The article evaluates two prominent ad‑spy platforms—AdPlexity and SocialPeta—to determine which offers greater practical value for marketers seeking competitive intelligence. AdPlexity is positioned as a versatile collector of advertising assets across multiple formats (desktop, mobile, push, native, adult, carrier, e‑commerce), boasting a large database but limited analytical depth. Its pricing model charges separately for each product line, ranging from $149 to $249 per month, which can become costly when multiple modules are required. In contrast, SocialPeta presents a more comprehensive analytical framework that covers 73 global channels and over 980 million ad materials across 46 countries. It provides advanced metrics such as CPC, CPM, CTR, CPA, and audience segmentation (education level, emotional status, geographic distribution). SocialPeta’s filtering system is markedly richer, offering criteria such as carousel, playable ads, proposal type, language, theme, impression data, and interaction metrics, enabling precise targeting. Pricing for SocialPeta is not publicly listed; users must request a quote via email, suggesting a potentially tailored enterprise approach. The comparison highlights that while AdPlexity excels in breadth of ad collection, SocialPeta delivers deeper analytical capabilities and more granular filtering, making it the preferred choice for advertisers prioritizing data-driven strategy over sheer volume of ad assets.
