In order to serve pop-up, pop-under, or floating creatives to your website, you’ll need to traffic the creatives using one of DFP’s built-in creative templates, and you’ll need to make sure your tags are set up properly to allow these creative types to serve.
Traffic a pop-up, pop-under, or floating creative in DFP
Follow the instructions for creating a creative from a template.
Set up your tags to allow pop-up, pop-under, or floating creatives to serve
In order for these creative types to serve to an ad tag, the tag needs to include the reserved key-value
dcopt=ist. This key-value does not need to be targeted during the trafficking process in DFP; it just needs to be in the tag.
When an ad tag containing
dcopt=ist calls the ad server to request an ad, it tells the ad server that it can accept both traditional creatives (creatives that serve into an ad slot on the page) and creatives that appear in a new window above or below the page.
A tag that has
dcopt=ist in it can serve two ads to one page: a traditional creative, and one pop-up, pop-under, or floating creative. In the example above, the tag could serve both a pop-under of any size and a 728x90 creative. Pop-ups, pop-unders, and interstitials do not officially have a size (example: a pop-up that is 300x250 could serve to the ad tag above).
DFP will only serve one pop-up, pop-under, or floating creative per page load.
As a best practice, we recommend always placing
dcopt=ist in the top tag on the page (and targeting that top ad slot size in DFP). You should only have
dcopt=ist in one tag per page.
For clients upgrading from DART, you no longer need to manually insert the
%i macro into your creatives; the templates will take care of that.
