This document provides guidance on how to choose a tag management system by outlining 8 key questions to ask potential vendors. It explains that tag management systems help address issues like website crashes, slow page loads, data leakage, slow deployment of new technologies, and privacy violations caused by improperly managed website tags. The 8 questions cover whether the vendor's solution can accommodate current and future tag needs, works with any third party technologies, has proven real-world implementations, integrates with marketing attribution platforms, is financially stable, minimizes additional vendors, provides strong customer service, and addresses privacy regulations. Choosing a vendor that satisfactorily answers all the questions can help companies maximize the benefits of tag management.
