There are two options available to configure refresh for your ad units:
Time-based refresh
Event-based refresh
Time-based ad refresh
This is configured in the ad unit settings and is used to get a new impression for an already initialized Sulvo tag based on time. Time-based ad refresh is configured in Inventory under the ad settings and is set to a 30-second refresh but can be configured for different timeintervals per ad unit.
Time-based ad refresh is very nuanced functionality that has many variables which can both help or hurt earnings. One of the biggest variables for ad refresh is ensuring that the visitor actually has the unit in-focus, and is in front of the window when the refresh happens. Without this, a refreshed ad could have very low performance and will drive down the ad placement value over time. Ensuring that the user is active on the page is, of course, complicated and requires much more than just having the tab open. Sulvo's time-based ad refresh functionality ensures that the ad is in-focus before refreshing.
Event-based ad refresh
To refresh a Sulvo unit from a click, route change, or infinite-scroll insert, call:
demandSupply.surge.refreshAd("example.com_300x250")
The argument is the root id (data-ad on the tag).
This does not stop the auto-refresh timer.
If the tag is in the DOM but has not displayed yet, refreshAd displays it.
googletag.pubads().refresh() is not this API. Fusion and other wrappers still cannot hop Sulvo units through GPT.
To refresh every currently displayed Sulvo unit all at once, use:
demandSupply.surge.refreshAllAds()
What should I configure?
Sulvo cannot give advice about the use of these features as results can vary greatly based on many factors and specific use case. Due to these variables, we have not enabled ad refresh by default and always recommend testing on each site for the best results.
This feature does not apply to interstitials, site-entry units, or focused display units.
