However, all videos share an aspect ratio of 16:9 \/ 9:16. Keep in mind that most ad platforms can automatically resize creatives to fit the placement, so there is no need to overstress about providing all the possible sizes. Instead, focus on providing a portrait or landscape HD resolution video (1080&#215;720 \/ 720&#215;1080) and an end-card of the same size.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-style-framed\"><img loading=\"lazy\" decoding=\"async\" width=\"995\" height=\"660\" src=\"https:\/\/persona.ly\/glossary\/wp-content\/uploads\/2023\/02\/The-anatomy.png\" alt=\"mobile end-card example\" class=\"wp-image-102\" srcset=\"https:\/\/persona.ly\/glossary\/wp-content\/uploads\/2023\/02\/The-anatomy.png 995w, https:\/\/persona.ly\/glossary\/wp-content\/uploads\/2023\/02\/The-anatomy-300x199.png 300w, https:\/\/persona.ly\/glossary\/wp-content\/uploads\/2023\/02\/The-anatomy-768x509.png 768w\" sizes=\"auto, (max-width: 995px) 100vw, 995px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading is-style-tape-blue\">MRAID (Mobile Rich Media Ad Interface Definitions) ads<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">MRAID is a standard API developed by IAB for the development of interactive mobile ads using HTML5 and Javascript.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">MRAID provides a comprehensive <a href=\"https:\/\/www.iab.com\/guidelines\/mraid\/\" rel=\"noopener\" target=\"_blank\">set of guidelines<\/a> to address interoperability problems between publishers&#8217; mobile apps, ad servers, and various rich media platforms. These guidelines cover various ad interactions, such as expanding, collapsing, resizing, and closing, as well as other features such as screen size, video playback, image saving, and more.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These ads can vary to be as simple as animated banners or as complicated as resembling the gameplay mechanics of an MMORPG.<\/p>\n\n\n\n<h2 class=\"wp-block-heading is-style-tape-purple\">Playable ads<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Playable ads are interactive ad units that mimic a short gameplay or native app experience. The goal is to let the user \u201cget a taste\u201d of the app before they install it. In our practice, playable ads are one of the most efficient ways to promote an app, as they <a href=\"https:\/\/persona.ly\/blog\/2017\/03\/playable-ads-101-all-you-need-to-know-about-playable-ads\/\" rel=\"noopener\" target=\"_blank\">eliminate the app discovery phase<\/a> and allow users to familiarize themselves with an app before downloading it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Playable ads sizes:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The standard development size for interstitial or full-screen playable ads would be: 1280&#215;720 \/ 1920&#215;1080 (landscape) and 720&#215;1280 \/ 1920&#215;1080 (portrait). However, it\u2019s crucial to test the rendering on multiple screen sizes to ensure a smooth user experience.<\/p>\n\n\n\n<div class=\"video-embed\"><div style=\"padding:211.11% 0 0 0;position:relative;\"><iframe src=\"https:\/\/player.vimeo.com\/video\/485041016?h=6041999475&amp;badge=0&amp;autopause=0&amp;player_id=0&amp;app_id=58479\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;\" title=\"Game of Lust - Playable\"><\/iframe><\/div><script src=\"https:\/\/player.vimeo.com\/api\/player.js\"><\/script><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Pros:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">&#8211; High performance due to being an extremely prominent format<br>&#8211; Interactive, allowing users to get a glimpse of the app<br>&#8211; Engaging format that ensures users who download the app are actually interested<br>&#8211; Very precise measurement (every interaction counts)<br>&#8211; Testing for new demographics and social segments<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cons:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">&#8211; Expensive inventory since playables take up the entire app screen (interstitial)<br>&#8211; Difficult to effectively create and utilize<br>&#8211; Can lead to poor user experience if there\u2019s poor execution and SDK adaptation<\/p>\n\n\n\n<div class=\"wp-block-group is-style-note\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"note-title wp-block-paragraph\"><strong>Pro tip: Playable is not just for games!<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Playable ads can help brands go far beyond the standard formats. For example, you can imitate every detail of the app experience and deliver top-notch creative concepts and playable experiences for non-gaming apps. An example of the latter might be having the user dress a mannequin for a shopping app.<\/p>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading is-style-tape-purple\">Mobile dynamic ads<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The dynamic ad is a format that is generated in real-time based on the aggregated behavioral data and previous interactions with an app. This allows for a more personalized and relevant advertising experience. Dynamic ads can be used across multiple placements, stretching from the smallest possible size to full-screen (interstitial).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The main advantage of dynamic ads is their ability to precisely target and engage the audience, leading to higher conversion rates and more efficient spending.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dynamic ads specs:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dynamic ads can fit any inventory size.

Testing the creatives is a trial-and-error path. To yield the best results, a programmatic DSP responsible for the delivery should be able to take multiple steps into consideration:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1) <strong>Choose the right combination of formats.<\/strong> It\u2019s relatively rare for a user to download the app after one ad view. Following the basic AIDA (attention &#8211; interest &#8211; desire &#8211; action) model, it typically requires a few impressions to convince the user. That\u2019s why it\u2019s important to consider which ads users will initially be exposed to and which ads will help them progress in the marketing funnel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2) <strong>Consult on the <a href=\"https:\/\/persona.ly\/glossary\/performance-metrics\/app-growth-metrics-the-key-user-acquisition-metrics-to-follow\/\">right performance metrics<\/a>.<\/strong> Programmatic buying works exclusively with CPM (cost per 1000 impressions) even if the final payment model is different. It\u2019s important to track the right metrics and have access to the granular insights to identify the best performing creatives based on their actual performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3) <strong>Don\u2019t stop testing.<\/strong> Check out our article on <a href=\"https:\/\/persona.ly\/glossary\/performance-metrics\/creative-testing-multi-armed-bandit-vs-a-b-testing\/\">creative testing<\/a> to see which approach works best for your app.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this article, we will review everything you need to know about mobile creative formats and their specs, performance, and best practices.It might seem that ads come in all shapes and sizes\u2014well, that\u2019s not exactly the case with mobile programmatic.
