# Extending Analytics

Data collection is essential to the Umbraco Engage Analytics feature. When a visitor requests a page on your website, the web request is analyzed for relevant information, which is then stored in the database.

However, there may be times when the data collected is not entirely accurate, or you might have additional data to complement the Umbraco Engage dataset. In the following articles, we will explain how to replace specific **extractors** that obtain particular pieces of information from a request.
