To optimize the effectiveness and coverage of your next mobile advertisement campaign, which mobile ad sizes do you concentrate on?

Mobile advertisements come in all shapes and sizes, but did you know that some are more effective than others? When learning how to build a display campaign, it’s critical to distinguish between the various smartphone ad sizes and concentrate on the ones that convert the most and have the most inventory. To save you time, we’ve compiled a list of the five best mobile ad sizes to concentrate on in 2021.

5 Best Mobile Ad Sizes for 2021

320 x 50 Mobile Leaderboard

Among the most common banner formats for portable devices is the 320 x 50 Mobile Leaderboard, also known as Smartphone Banner by the Interactive Advertising Bureau (IAB). According to statistics, mobile leaderboard ads account for 12% of all international ad impressions.

The proportions of mobile leaderboard advertisements are close to those of conventional desktop banner ads, but they’ve been optimized to fit into the restricted viewport of mobile devices. Mobile leaderboards, as one of the smaller ad units available, can be useful when used as an overlay/anchor ad at the end of a web page.

300 x 250 Inline Rectangle

This 300 x 250 Inline Rectangle is one of the most relevant mobile ad sizes to plan and optimize your creativity while you’re building a campaign. Inline Rectangle advertising, often known as “Medium Rectangle” ads by the IAB, adapt well for advertisers and generate revenue for publishers, so everybody benefits.

Inline Rectangle is one of the most common ad sizes for both computers and mobile phones. According to intensive analysis, 300 x 250 ad slots could account for up to 40% of global advertising inventory. Inline rectangular advertisements may be seen on websites or as an in-app ad.

728 x 90 Leaderboard Banner

The size is 728 x 90 pixels. While the leaderboard is a banner ad format that is most often used on desktops, it does have a role in smartphone ads that publishers should be aware of. Leaderboard banners aren’t available on mobile, but they are one of the biggest banner ad units available on tablet devices.

Leaderboard ad slots account for about 25% of global show ad space, but even though you’re just reaching tablet devices, you should be able to attract a larger audience for leaderboard advertising than for any other smartphone ad format.

320 x 100 Large Mobile Banner

320 x 100 large mobile banners are one of the top 5 most popular mobile ad formats, according to many ad networks. The large mobile banner is double the size of the regular 320 x 50 mobile leaderboard banner and suits the size of smartphone screens. Advertisers now have twice as much space to deliver a persuasive message that attracts views.

Although the smaller and less invasive smartphone leaderboard format can be used as a sticky ad, overlay, or anchored ad unit, 320 x 100 advertisements are more effective when easily combined with the publisher’s material.

336 x 280 Interstitial Ads

Users see interstitial advertisements when using a website, app, or smartphone game as part of their normal browsing experience. Interstitial advertisements appear where there are gaps in the flow of content, such as among videos, stages of a video game, or when an operation is completed. They usually take up the entire screen of the user’s computer and can include interactivity to encourage user interaction.

Many platforms monetize apps with smartphone advertising. However, you must choose the right choice for your app. MediaFem is one of the most popular mobile advertising platforms in 2021. This is a big UK-based platform with more than 10 years of program monetization. Numerous websites use ad codes for visitors to read more posts or generate revenue from referral traffic on the same page.

Publishers can use the advanced analytical engine-driven platform to do A/B checking, smarter reports and personalization, which are all essential for online technological progress. For their services, publishers can choose between header bidding and the traditional One Ad Code solution. This ad network offers a variety of video, mobile, audio and native ad formats.

MediaFem does not charge commissions and follows a 70% Rev. Publisher share model and pays Net53. These numbers are distributed to all publishers, but they are not averaged, regardless of the region. With all sorts of ads suitable to your app, MediaFem is the most powerful platform to make big sums of money for advertisers and small publishers.
