Banners Guide

Learn how to create and manage ad creatives (banners), configure banner types, set targeting rules, and optimize banner performance.

What is a Banner?

A banner is an individual ad creative that is displayed to users. Banners can be images, HTML, text, or video. Each banner belongs to a campaign and can have its own targeting rules and delivery limitations.

Cogniad supports multiple banner types:

Image Banners

Standard image banners in formats like JPEG, PNG, GIF, or WebP. Most common banner type, suitable for display advertising.

HTML Banners

Custom HTML code that can include JavaScript, CSS, and interactive elements. Provides maximum flexibility for creative design.

Text Banners

Simple text-based ads with title, description, and click URL. Lightweight and fast-loading.

Video Banners

Video ads with VAST support. Can be hosted externally or uploaded to Cogniad.

Creating Banners

Create a banner using the API:

javascript 
// Image banner
const formData = new FormData();
formData.append('campaign_id', 'camp_123');
formData.append('name', 'Summer Sale Banner');
formData.append('type', 'image');
formData.append('width', '728');
formData.append('height', '90');
formData.append('file', imageFile);
formData.append('click_url', 'https://example.com/summer-sale');
formData.append('alt_text', 'Summer Sale - 50% Off');

const banner = await fetch('https://api.cogniad.com/v1/banners', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${access_token}`
  },
  body: formData
});

const bannerData = await banner.json();

Banner Dimensions

Common banner sizes (in pixels):

  • 728x90: Leaderboard
  • 300x250: Medium Rectangle
  • 320x50: Mobile Banner
  • 160x600: Wide Skyscraper

Banners can have their own targeting rules in addition to campaign-level targeting. Banner targeting rules are combined with campaign rules using AND logic.
