BEST MOBILE AD SIZES IN 2019: FIND OUT WHICH BANNER UNITS (STANDARD, SMALL & GOOGLE OPTIMIZED)

With an estimated 5 billion mobile users on the planet, engagement with mobile devices is higher than ever and continuously growing. People of all ages, generations, and genders are using their devices wherever they go, some for even for hours per day. These users get bombarded by messages, news events, and social media on a daily basis – all very distracting. This increases the need for mobile ads to be attention-grabbing, placed in optimal digital spots for maximum viewability while utilizing the best banner sizes for maximum revenue generation for publishers and successful campaign management for advertisers.

THE 300×250 AD UNIT GOOGLE UPDATE

In 2017 Google changed their mobile ad types policies and removed restrictions placed 300×250 units above the fold. After rigorous testing, Google determined that these 300×250 ads can be implemented above the fold in a way that does not annoy or distract users.

This change is excellent news for publishers as it gives them a chance to earn better CPMs (cost per thousand impressions). Since the 300×250 unit is a high performing ad unit, being able to place it above the fold leads to good viewability and a high potential for user engagement.

MORE MOBILE AD UNIT SIZES TO CONSIDER

Larger advertising formats (e.g., mobile interstitial ad sizes) have been proven to be better at capturing the user’s attention and paying the best CPM rates, but publishers should be careful with intrusive ad formats in 2019 on both mobile and desktop versions of their sites. Effective February 15, 2018, Google will update it’s Chrome browser with a built-in ad blocking tool in agreement with the Coalition For Better Ads standards and will stop showing all ads on sites that have been in “Failing” status for more than 30 days.

Be sure to read our Google Chrome Adblock Policy Update 2018 post to find out how to check if your mobile ads comply and to fix any potential issues. There’s a non-stop search for creative ways to deliver ads on mobile, thus the birth of these large ad formats which up to now, continues to grow. In a recent study from Adpiler, 300×250 mobile ad size was found to be the most popular ad size. 34% of all ad impressions is this medium rectangle.
