Sentinel

Sentinel tracks which ads actually drive purchases using first-party pixel attribution instead of platform-reported numbers. The app installs a lightweight pixel on your store and matches ad clicks to real Shopify orders, showing you true ROAS, CPA, and revenue by campaign, ad set, and ad. Get accurate ad attribution across Meta, Google, TikTok, and Amazon with server-side Conversion API support for Meta and Google Enhanced Conversions. The app includes AI-powered creative fatigue detection that tells you when to rotate ads, plus multi-touch attribution models like linear, time-decay, and position-based tracking to understand your customer journey better.
