These include standard static files (JPG, PNG), simple animated files (GIF), and modern, responsive HTML5 banners (usually sent as a ZIP package). What is the maximum banner file size?CollapseExpand A very restrictive requirement is file size – whether it's a small graphic for mobile devices or a large banner for desktop, a single file cannot exceed 150 KB. This requires careful image compression. Which banner sizes should you prepare first?CollapseExpand While there are dozens of sizes available, it's best to focus on the most popular ones, which generate the most impressions. These include: 300×250 (medium rectangle), 728×90 (long banner), 160×600 (wide skyscraper), 300×600 (half-page banner), and mobile formats like 320×100. What are the main rules for animation (GIF and HTML5 banners)?CollapseExpand The animation in the banner cannot run indefinitely – its maximum duration is 30 seconds. It can loop, but must stop completely after that time. For GIFs, the animation cannot be faster than 5 frames per second (fps). What graphic design mistakes should you avoid?CollapseExpand Google will reject banners that attempt to deceive users. Elements resembling system notifications, Windows errors, or fake mouse cursors or "Close" buttons (crosses) are prohibited. The banner must have a clear border (if the background is white), a legible company logo, and a clear call to action.SummaryThe above article covers the following topics:technical requirements for remarketing banners,types of static graphic ads,types of animated ads.Related Articles Google Display Network (GDN) - how to reach customers with images?
