Omnitrail is an advertising attribution and optimization platform designed to help ecommerce businesses understand which marketing activity drives revenue. It brings together storefront, session, order, and advertising data to deduplicate conversions and compare actual performance with the figures reported by individual platforms. This helps teams assess return on ad spend, customer acquisition cost, and revenue across channels such as Google, Meta, TikTok, Pinterest, and email.

The platform offers server-side tracking, identity stitching, cross-channel analysis, and five attribution models: Linear, First-Click, Last-Click, Data-Driven, and AI-Powered. Users can compare models, examine customer journeys, and review campaign-level results in a shared dashboard. Omnitrail also supports budget optimization, AI-assisted advertising automation, and rolling forecasts for revenue, acquisition costs, and return on ad spend. Its integrations include ecommerce platforms such as Shopify and WooCommerce, alongside major advertising services. With one connected workflow spanning tracking, analysis, optimization, automation, and forecasting, Omnitrail aims to give marketing teams a clearer basis for allocating spend and scaling campaigns.
