Plain-language definition
What is display banners advertising?
Display banners are visual ad units placed inside a page or application layout. They are familiar and scalable, but effective delivery still depends on creative dimensions, placement context, viewability, frequency and transparent supply paths.
Delivery path
From opportunity to measurable outcome.
The exact services differ by format, but every useful implementation keeps eligibility, delivery and evidence connected.
Measurement
Metrics that explain more than volume.
Counted ad deliveries
Opportunity to be seen
Clicks ÷ impressions
Revenue normalized per thousand impressions
Operator guide
What clients should understand before launch.
What the user sees
A rectangular creative appears inside the surrounding page or application. Common units include leaderboards, medium rectangles and mobile banners, with responsive or HTML5 variants adapting to available space.
How delivery works
The placement sends context such as size, environment and publisher identity. Eligible campaigns or bidders respond, the winning creative is returned and impression, viewability and click events are recorded.
Creative requirements
Dimensions, file weight, destination URL, animation behavior, fallback assets and secure delivery must match the placement contract. A visually strong banner that cannot render quickly still loses value.
Operator watchouts
Hidden placements, excessive refresh, domain or app misrepresentation, poor viewability and uncontrolled frequency can inflate delivery without producing useful attention.
Frequently asked
Questions about display banners.
There is no universal best size. Use the sizes supported by the target inventory and prepare responsive or multiple creative variants without sacrificing load performance.
CPM is a buying price per thousand impressions. eCPM normalizes actual spend or revenue so performance across different pricing models can be compared.
Not necessarily. An impression records delivery; viewability adds evidence that enough of the creative entered the visible viewport for a defined period.
