It only has a time reference. --- ## Time categories By using time [categories](/docs/categories-and-parameters), numeric values can be imported. The data is allocated to an hour of a day. **Examples:** - Number of available products per day - Qty online orders (for quality control) - Qty offline orders - Individual target values (for calculating target achievement) | Time (YYYY-MM-DD HH) | Time category "Qty online orders" | Time category "Target orders" | | --- | --- | --- | | 2026-12-10 00 | 5,664 | 5,500 | | 2026-12-11 00 | 5,581 | 5,000 | | 2026-12-12 00 | 5,405 | 5,000 | ### Good to know Time categories are available as metrics. ### Setup & best practices - [How to set up categories](/docs/how-to-set-up-categories) - [Import individual target values and monitor their achievement](/docs/kpis-import-individual-target-values-and-monitor-their-achievement) --- ## Independent parameters Independent parameters can be used to log additional information per tracking request. They are only linked by time — not to a page, click, or visit — so tracking one does not create a visit. **Examples:** - Adserver tracking - IoT tracking - Newsletter openings in an email client The exact syntax depends on your integration method. For details, see [Tracking Integration](/docs/tracking-integration). ### Analysis Available in *Visitors > Independent Parameters* (for the data type Text). ### Setup - [How to set up custom parameters](/docs/how-to-set-up-custom-parameters)
