Banner Ads
Standard display advertising format using static or animated images in fixed placements.
Definition
Banner ads are standardized display advertising units that appear in designated spaces on websites and apps. They follow IAB-specified dimensions and can include static images, animated GIFs, or HTML5 animations. While traditional in format, modern banner ads incorporate responsive design, dynamic creative optimization, and sophisticated targeting to maintain effectiveness in an evolving digital landscape.

Responsive banner ads that adapt to different screen sizes
Frequently asked questions
Common questions about Banner Ads, answered.
What are banner ads?
Banner ads are image-based display ads — static or lightly animated — placed in defined slots on websites and apps, typically sold and served programmatically. They're one of the oldest digital ad formats, used mainly for awareness, retargeting, and driving clicks to a destination. Standard sizes (like the leaderboard and medium rectangle) let them slot into publisher inventory across the web.
What are standard banner ad sizes?
Common IAB standard sizes include the leaderboard (728×90), medium rectangle (300×250), large rectangle (336×280), wide skyscraper (160×600), and mobile leaderboard (320×50), among others. The medium rectangle and leaderboard are among the most widely supported. Producing a banner set across several standard sizes maximizes the inventory it can fill across publishers and devices.
What is banner blindness?
Banner blindness is the well-documented tendency of users to consciously or unconsciously ignore banner-style ads, having learned where ads sit on a page. It's why standard banners often see low click-through rates and why creative must work hard — clear value, strong visual hierarchy, and a crisp CTA — to overcome the instinct to skip past them. It's also part of why native and rich-media formats emerged.
Are banner ads still effective?
They remain useful for low-cost reach, retargeting, and reinforcing awareness, especially programmatically at scale — but they carry low engagement due to banner blindness and are easy to ignore. They're rarely a primary direct-response driver today. Used as part of a mix (retargeting warm audiences, maintaining presence) rather than the main conversion engine, banners still earn their place; as a standalone strategy they underdeliver.
Banner ads vs native ads — which should I use?
Banner ads are distinct, easily-recognized blocks — cheap and scalable but subject to banner blindness. Native ads match the surrounding content's format, earning more attention and engagement but requiring content that fits the context and clear paid labeling. Use banners for inexpensive reach and retargeting; use native when engagement and blending into the feed matter. Many programs run both for different goals.
