# Best Tag Management Systems - Page 4

*By [Alanna Iwuh](https://research.g2.com/insights/author/alanna-iwuh)*


A tag is a short piece of Javascript code that is embedded on web pages, mobile applications, and other relevant digital channels to collect first-party user data. Tag management systems simplify and unify the management and maintenance of tags across all digital properties. This is important because the collected data from those tags equips companies with insight to drive better customer experience. With tag management systems, marketers can consolidate and standardize the process of updating tags (streamlining any digital marketing campaigns) and reduce dependence on their IT or development teams. Furthermore, tag management software encourages agility. These solutions provide containers through which marketers can easily add, edit, or remove tags at will. Tag management systems can vary in functionality, with the most advanced versions offering customization and data management.

To qualify for inclusion in the Tag Management category, a product must:

- Collect, and then centralize, user data
- Offer a simple interface for users both familiar and unfamiliar with code
- Provide a library or catalog of tags
- Deliver tag-testing capabilities or integrate with [A/B testing solutions](https://www.g2.com/categories/a-b-testing)
- Track and monitor user engagement and other user behaviors
