# Static vs Dynamic

**Static:** Once Saved, the segment will stay the same unless manually edited. This means that once you save an audience it will not auto-update.&#x20;

**Dynamic:** Once Saved, the segment will continue to update in order to meet the parameters of the segment. All automations must use Dynamic segments in order to work properly.&#x20;

For example: If you set up a segment of users who visited in the last 7 days, each day people who visited 8 days ago will leave the segment and people who visited 1 day ago will enter the segment.&#x20;
