With Boltive's blocking solution offering many different block types (ex: malicious, category, custom) and refresh options for other vendor blocks (ex: HAI, DV, etc.), it's possible that one ad slot will see several blocks in a row. The Default Fallback Tag option allows for the ad slot to not be empty in the event an ad is blocked and refreshed multiple times.
How It Works
After any Boltive block with the standard integration, we are able to refresh the slot via the GPT refreshSlot mechanism (for a refresher, more information can be found HERE)
An ad can be blocked 3 times total in a row, with the standard block/refresh pattern happening twice. On the third block in a row, the ad slot will remain blank until the standard page refresh (20-30 sec).
By supplying Boltive with a Default Fallback Tag, in the event there are three
blocks in a row, rather than having the ad slot be blank the default tag will serve
How To Enable
Send Boltive a tag that is compatible to support various sizes. When we set the Default Fallback Tag, we will replace %%WIDTH%% and %%HEIGHT%% with the ad iframe’s size.
