To make your work easier, the site list has filters and supports bulk actions:
To display only the sites you need, click and select filters by name, type, status, strategy, or other parameters.
To go to bulk actions, select the desired sites. A context menu with available actions opens:
Stop impressions: Stop impressions for all ad units on the selected sites.
Start impressions: Restart ad impressions on the site.
Tip
Bulk actions are applied only to sites listed on your current page. To process more sites at once, scroll to the bottom of the list and set the number of lines displayed per page to 100.
