Mobile ads have become more important than ever before. We use cell phones for almost everything in our lives from Facebook to emails to Google searches. Cell phones have allowed us to have access to the internet at the tip of our fingers (almost) anywhere at given anytime. Hitwise reported that ~58% of all search queries in the US are from mobile searches. This means that in this day and age one of the best ways to reach consumers is via mobile ads! Mobile ads have given marketers with new touch points to reach consumers.

IAB’s New Ad Portfolio

IAB’s New Ad Portfolio has created a guideline for the best practices for format and sizes of all ads. IAB introduces a standard ad unit and LEAN principles (Light, Encrypted, AdChoices supported, and Non-invasive) combining these to improve user experience and maximize publisher load performance.  An ad unit is defined by set aspect ratios and minimum and maximum size ranges. The aspect ratio allows ads to have flexible sizing within the set ranges based on the screen size of the device being used.

Before this, standard ads used fixed pixel ranges that did not fit on all size screens. It’s extremely ineffective to have an ad that is only partially displayed on a user’s device. LEAN principles simply imply that having lightweight files minimize upload time and properly placed, non-invasive ads create a more enjoyable user experience. It is advised to use IAB’s New Ad Portfolio whenever creating an ad.

Mobile Ad Types

Banner

Banners are the oldest, simplest form of mobile ads, which also make banners the most popular ad type. It’s simply a banner that includes text and/or graphic placed at the top or bottom of the screen. Marketers can make these ads static or animated. Often, a banners success depends on brand recognition therefore widely known brands can leverage the small space without needing additional information.

Example:

banner_ads

Best Practices for Creating Banner Ads

  • Aspect ratio: 6:1 (min: 300×50 pixels, max: 450×75 pixels)
  • Max size: 100Kb
  • Only highlight key feature(s) to avoid cluttering up the small space
  • Have a clear call-to-action
  • Simple practical designs by avoiding bright colors, too much text, and mediocre graphics.

Experts say “banner design needs a careful balance with subtle eye-catching content yet not too distracting”

Pros of Using Banner Ads:

  • Compatible on all screens
  • Executable in large volumes
  • Cheapest format to produce
  • Little time needed to utilize
  • Uncomplicated integration

Cons of Using Banner Ads:

  • Low eCPM (effective cost per mille) [eCPM = ad revenue generated ÷ number of ad impressions]
  • Low CTR (click through rate)
  • Low engagement rate
  • Banner Blindness – When users unconsciously or consciously ignore banners due to its passive nature.
  • Limited space
