loadAd

loadAd is a method used in digital advertising software development kits (SDKs) to initiate the retrieval of advertisement content from an ad server or demand source. It is commonly used in mobile apps and web environments to fetch formats such as banners, interstitials, native ads, or rewarded videos.

The loadAd process is typically asynchronous. A caller provides information about the desired ad (such as an ad unit identifier or placement and optional targeting data), and the SDK makes a network request to an ad server. If a suitable ad is found, the ad content is returned and prepared for display; if no ad is available or another error occurs, the call returns an error or a no-fill response.

Commonly, loadAd involves several parameters or settings, including an ad unit ID, an ad request with targeting and context data, and a callback or listener to handle success or failure. Some implementations separate concerns into an ad loader object and a separate ad object that represents the loaded creative. The exact API varies by platform, but the general pattern is to request an ad, wait for a response, and then render the ad when ready.

Usage patterns include preloading ads in advance of user interaction, refreshing ads at appropriate intervals, and integrating with mediation layers that select ads from multiple networks. Developers must handle errors such as network failures, invalid ad unit IDs, or no-fill situations, and consider privacy and consent requirements when collecting targeting data.

Example (pseudo-code):

loadAd(adUnitId, adRequest, onAdLoaded, onAdFailedToLoad)
