Open new ad placements on the page that weren't part of the original layout, or upgrade the creative that runs in the slots you already have. New placements add revenue surface area through formats like interstitials, exit-intent overlays, page-grabbers, takeovers, mastheads, anchor and sticky units, and in-article video players. Rich media upgrades swap a static unit for an expandable, video-enabled or interactive one in the same slot: same inventory count, higher value per impression, lower UX disruption. Common vendors: Kargo (Spotlight), GumGum (Hangtime, Skins, in-image, in-screen), Celtra, Clipcentric, Wunderkind (Exit Intent Modal), Perion/Undertone (Page Grabber), Concert, Lupon Media (sticky), Exitbee, Display.io (Interscroller), Primis (in-article video player), Google Ad Manager (Web Interstitial). Tradeoffs: incremental revenue, but higher UX cost for new placements, Google policy exposure (especially for interrupting formats), and ops complexity. Frequency capping, exit triggers, and creative QA are essential.

Before scaling interstitials, compare exposed visitors against a holdout on revenue per session, dismissal rate, bounce rate and session depth.
