Description
Spillmark is an online analytics and experimentation tool designed specifically for Amazon sellers utilizing Meta ads. This platform integrates data from Amazon Seller Central, Amazon Ads, Meta, and optionally Shopify, allowing users to assess their sales, expenses, fees, advertising costs, and overall channel profitability through various connections and report imports. Sellers have the capability to create and execute geographic holdout tests, which involve pausing Meta ads in designated areas to compare Amazon sales and evaluate the incremental impact of their advertising efforts. The findings are presented with uncertainty ranges and detailed explanations of the methodologies employed, complemented by dashboards, notifications, and documentation of test designs. Access to connected accounts is strictly read-only, ensuring that the product does not modify any campaigns without the seller's consent. Additionally, Spillmark offers an MCP server and REST API for integration with assistants and scripts, enhancing its usability. Currently, brand-level measurement and tailored recommendations are in a private beta phase. The platform's Starter package allows for one active holdout test and provides alerts, while the Growth package offers unlimited tests, live account connections when applicable, and customized Amazon PPC tests, catering to the evolving needs of sellers as they scale their operations. Through innovative features and user-friendly design, Spillmark aims to enhance the marketing strategies of Amazon sellers.
Description
Stella is a platform designed for marketing measurement, providing marketers with robust, scientifically validated insights into which advertisements, campaigns, and media channels effectively contribute to increased revenue. The platform is equipped with three primary tools: Incrementality Testing, Always-On Incrementality, and Media Mix Modeling (MMM). Through Incrementality Testing, Stella conducts geo-holdout studies, also known as inverse holdouts, to evaluate performance differences between test and control areas, effectively isolating the causal effects of advertisements as opposed to relying solely on attribution methods. This tool simplifies complex statistical processes, including causal inference and confidence intervals, allowing users to understand the potential outcomes without a specific campaign, thus uncovering the genuine “lift” attributed to each advertisement. Furthermore, its Media Mix Modeling feature employs a unique Bayesian approach to dissect historical marketing expenditures and various external influences, such as seasonality and promotional events, to assess the contribution of each channel to overall sales effectively. By leveraging these advanced methodologies, Stella empowers marketers to make informed decisions based on accurate data analysis.
