Refreshing inventory updates ad content without necessarily having to refresh the entire contents of your page. You may choose to allow ads that dynamically reload to provide a better user experience or meet industry standards.
You can set a refresh rate for ad units in Ad Manager settings, and implement refreshes using GPT.
Ad inventory that refreshes is allowed to compete. However, you must declare which portions of your inventory refresh per advertising industry guidelines on refresh transparency. Adding declarations on refreshing inventory in Inventory rules lets buyers know, through the Real-Time Bidding Protocol, that they're purchasing refreshing inventory, the triggers that cause the refresh, and the minimum interval to expect between refreshes.
Failure to declare inventory that refreshes or improperly declaring it (for example, declaring the wrong trigger type or refresh interval) is a violation of Google policy, and we will notify you of any violations we detect.

A sticky ad is a persistent/fixed ad unit that stays visible while the user scrolls content on the page up or down. - Check the boxes under "Refresh triggers" to indicate that the selected inventory refreshes. You can select one or more refresh types for the same inventory, and each declaration applies to all targeted impressions.
- For each refresh trigger that you declare, specify the minimum time interval between ad refreshes. This declares to buyers that the ad content for this inventory will not refresh any faster than the interval you selected.
- Click Save.

to the right of the selection. Rules only allow you to declare that ads refresh; they do not control the behavior of ads on the page. Declaring an ad unit as refreshing in the UI doesn't implement refreshes on your inventory.
We recommend using user action or event-driven refreshes when possible as the behavior of ads on your web pages must match what you declare to publishers in Ad Manager.
