# Tags
Use tags to organize and manage your [feature flags](/feature-management-experimentation/new-to-fme/get-started/create-a-feature-flag.md), [segments](/feature-management-experimentation/use-fme/feature-management/targeting/segments.md), [metrics](/feature-management-experimentation/new-to-fme/get-started/create-a-metric.md), and [experiments](/feature-management-experimentation/new-to-fme/get-started/create-an-experiment.md) in Harness FME. Tags can represent a particular team or feature release, e.g., *reporting team*, *front end*, or *geo search release*.
Harness recommends creating tags that are specific to your workflow. For example:
| Category | Description | Example tags |
| ------------------------------ | ----------------------------------------------------------------------------------- | -------------------------------------------------------------- |
| By team | Identify the responsible team. | `front end`, `infrastructure`, `web`, `mobile` |
| By feature release | Group flags associated with a specific release. | `reporting`, `new permissioning`, `contact database migration` |
| By feature flag type | Categorize flags related to paywalls or whether they're permanent or temporary. | `paywall`, `permanent`, `temporary` |
| By experiment purpose or scope | Group experiments related to onboarding, checkout flows, or other test initiatives. | `onboarding`, `checkout`, `retention-test` |
### Adding tags
You can add tags to feature flags, segments, metrics, and experiments. Tag names are case sensitive, and tags are shared across projects. The process is similar across all FME objects, but the UI controls differ slightly.
Allowed characters for tag names include the following:
* Letters: `a-z`, `A-Z`
* Numbers: `0-9`
* Separators: `-`, `_`, `:`
