- Optimizely Feature Experimentation

You can schedule changes to an existing [flag](docId\:eH-UMm_rOn_GdGDGLV6__) or [rule](docId:-yq2-thNRv7-SgwCXpG90), such as:

- Turn a flag [on or off](docId\:F8tdFPnxECabBXsQkBqDt).
- [Play or pause](docId\:F8tdFPnxECabBXsQkBqDt) a rule.
- Update the percentage of traffic included in a rule.
- Update the targeted [audience](docId\:UDBvr5a8WHNkyOqzPhOr9).

**Note**

If you intend to change the traffic's ramp percentage after running the experiment, you will need to implement a user profile service before starting the experiment.

For information, see [Ensure consistent user bucketing](docId:0mbVhcaiWJm6M96ZohwI-).
