In modern digital marketing, success depends not only on strong creativity and a clear message. The outcome of a campaign is often shaped by how carefully the technical requirements of advertising platforms are followed. Ignoring these guidelines frequently leads to launch delays: materials fail moderation, require revisions, consume additional time and budget, and ultimately cause the team to lose opportunities in a fast-paced, competitive environment.

Each advertising platform operates according to its own rules, with specific formats, limitations, and technical parameters that must be considered during campaign preparation. This is especially true for systems like Meta Ads, Google Display & Video 360 (DV360), and direct placements. When creatives do not meet platform requirements, it can not only delay the launch but also degrade the quality of ad delivery — ultimately affecting conversions and the overall return on advertising investment.

General Recommendations for All Platforms

Before diving into the specific requirements of each advertising platform, it’s important to consider several universal principles. These guidelines help streamline the preparation process, reduce technical errors, and maintain consistent creative quality across all placements.

Basic Rules for Preparing Materials

1. A clear understanding of formats and sizes. Always check the latest technical requirements before starting work. Platforms update their standards regularly, and outdated information can easily disrupt a launch.
2. Optimal file quality. Maintain a balance between file size and visual clarity. Files that are too large slow down ad loading, while excessive compression makes creatives look unpolished.
3. Brand guideline compliance. Technical adjustments should not compromise visual identity. Adapt materials to platform requirements while preserving the key elements of the brand.
4. Correct file formats. Use JPG and PNG for static images, MP4 and MOV for video, and GIF for animations.
5. Responsive design. Ensure your creatives display correctly across different devices and placements.

Common Mistakes and How to Avoid Them

Advertising materials are most often rejected due to the following issues:

• Excessive file size. Check platform limits before uploading and optimize your files to ensure fast loading and avoid delays.
• Incorrect aspect ratio. Use templates and recommended dimensions for each placement — this ensures proper display of your creatives.
• Low resolution. Make sure images and videos are clear enough, especially for large or adaptive placements.
• Too much text. Monitor the amount of text in your creatives. For Meta, this remains a significant factor in moderation.
• Content policy violations. Always review the platform’s rules regarding prohibited topics, formats, and sensitive content to prevent rejections during moderation.

The Importance of Backup Content for Different Platforms

Having backup creatives is a reliable safeguard against delays, extra costs, and stressful last-minute revisions if your primary materials are rejected. Even minor changes in platform policies or technical limitations can halt a campaign launch.

It is recommended to:

• Prepare multiple versions of creatives with different text-to-image ratios. This is especially useful on platforms where text limitations affect delivery or moderation.
• Have static banner versions available. If animations or videos are restricted, disallowed, or load too slowly, a static banner can quickly resolve the issue.
• Develop alternative key messages. If the main message fails moderation, you can immediately replace it with a compliant version without delaying the launch.
• Create adaptations for various formats and sizes. The same idea may work in feeds, Stories, banner grids, or native placements — but each has its own technical constraints. Ready-made adaptations significantly speed up the process.

Meta Ads: Technical Requirements

Meta Ads (formerly Facebook Ads) is known for having some of the strictest technical requirements, especially when it comes to balancing text and visual elements within creatives. To avoid rejections and ensure proper ad delivery, it is essential to follow the core specifications.

General Image Requirements for Feed Ads

• File formats: JPG or PNG
• File size: up to 30 MB
• Aspect ratio: recommended 1.91:1 (e.g., 1200 × 628 pixels)
• Minimum resolution: 1080 × 1080 pixels
• Text on images: no more than 20% of the image area — this reduces the risk of delivery limitations or reduced reach

Video Requirements for Feed Ads

• File formats: MP4, MOV, or GIF
• Duration: ideally 15–30 seconds for the news feed; up to 15 seconds for Stories
• Aspect ratios: 16:9, 1:1, or 9:16 depending on placement
• File size: up to 4 GB
• Resolution: minimum 720p
• Audio: bitrate of 128 kbps or higher

Placement Specifics for Stories

• Recommended aspect ratio: 9:16
• Optimal size: 1080 × 1920 pixels
• Safe area: the central 80% of the frame — this section remains unobstructed by interface elements
• Video duration: up to 1 minute

Google Ads: Effective Banner Sizes

There is no single “best” banner size in Google Ads, but in practice, the formats 300 × 250 and 728 × 90 tend to perform the best.

To achieve the widest possible reach, it’s important to prepare multiple banner variations in different — preferably compact — sizes. This ensures compatibility with most ad placements across websites and prevents missed impressions due to format mismatches.

Effective and Popular Sizes for Desktop

• Medium rectangle: 300 × 250
• Large rectangle: 336 × 280
• Leaderboard: 728 × 90 — typically placed at the top of the page
• Half-page / large skyscraper: 300 × 600

Effective and Popular Sizes for Mobile Devices

• Medium rectangle: 300 × 250
• Large rectangle: 336 × 280
• Mobile leaderboard: 320 × 50
• Large mobile banner: 320 × 100
• Square: 250 × 250
• Small square: 200 × 200

Performance Max

Performance Max is a Google Ads campaign type that provides access to all Google advertising channels within a single campaign. It complements keyword-based search campaigns and helps increase conversions by utilizing every available Google placement.

For Performance Max, it is important to follow these technical requirements:

• Allowed file formats: JPG or PNG
• Maximum file size: up to 5120 KB
• Safe area: place all key visual elements within the central 80% of the image — this zone will not be cropped during automatic creative adjustments across different placements

For a fully structured Performance Max campaign, you need to prepare several types of images:

• Horizontal images with a 1.91:1 aspect ratio — 4 versions, 1200 × 628 pixels
• Square images with a 1:1 aspect ratio — 4 versions, 1200 × 1200 pixels
• Vertical images with a 4:5 aspect ratio — 2 versions, 960 × 1200 pixels

If an image has a different aspect ratio, Google Ads provides built-in cropping tools, allowing you to adjust it directly within the interface.

In addition to the main images, you also need to prepare logos for the campaign:

• Square logo (1:1) — 1200 × 1200 pixels
• Horizontal logo (4:1) — 1200 × 300 pixels

You can upload up to 5 versions for each logo type.

For the best results, use high-quality, sharp images that clearly represent the product or service. Avoid excessive text and keep essential elements within the safe area to prevent cropping. Logos should be clean, clear, and easily recognizable.

Video Requirements

For Performance Max campaigns, it is recommended to use up to 5 video assets. If you don’t have your own videos, the system will automatically generate them based on your uploaded images and banners. Key requirements and recommendations:

• Video duration: over 10 seconds
• Maximum number of videos: 5
• Recommended formats: include at least one square, one horizontal, and one vertical video to ensure proper display across all Google placements

More detailed technical requirements for video ads can be found in the Google Ads Help Center.

DV360: Creative Material Preparation Guidelines

Google Display & Video 360 (DV360) is a powerful programmatic platform that offers a wide range of advertising formats. Each format comes with its own technical specifications, so it’s important to account for platform requirements during the creative preparation stage.

Standard Display Banners

• File formats: JPG, PNG, GIF
• Most common sizes: 300 × 250, 336 × 280, 728 × 90, 300 × 600, 320 × 100
• Maximum file size: 150 KB
• Animation: up to 30 seconds, with a frame rate of no more than 5 fps

Rich Media Banners

• Format: HTML5
• Maximum initial load size: 200 KB
• Maximum expanded size: up to 4 MB
• Maximum video duration within the banner: 30 seconds

More details about banner specifications in DV360:

DV360 also supports YouTube placements, which include dedicated formats with their own technical requirements, such as Non-skippable and Efficient Reach.

YouTube Non-Skippable Ads

For this video ad format, the video must first be uploaded to your YouTube channel, and then provided in the campaign as a link to the YouTube video. There is no need to send or upload the video file itself.

Video requirements:

• Duration: 6 to 20 seconds
• Orientation: primarily horizontal — this ensures proper display across most devices
• Additionally: to increase the player size on mobile devices, it is recommended (though not mandatory) to prepare a separate vertical version of the video

Companion Banner

This is an additional element displayed in the top-right corner on desktop. You can replace it with your own creative if desired. If no banner is uploaded, Google will automatically generate one based on the content of your YouTube channel.

Banner requirements:

• Size: 300 × 60
• File formats: JPG, GIF, PNG
• Maximum file size: up to 150 KB
• GIF animation: frame rate below 5 fps

YouTube Efficient Reach

Efficient Reach campaigns are optimized to deliver the widest possible reach within the target audience at the lowest achievable cost per impression. For this reason, it is crucial to ensure that all technical video parameters are correct, allowing the algorithm to scale delivery effectively across different devices and placements.

Video

The upload process is the same as for Non-skippable ads: the video is uploaded to your YouTube channel, and a link to the video is provided in the campaign — there is no need to send or upload the video file itself.

Video requirements:

• Duration: must match the specifications indicated in the corresponding line of the media plan
• Orientation: horizontal — to ensure proper display across all device types
• Additionally: to increase the player size on mobile devices, it is recommended (though not required) to prepare a separate vertical version of the video

Companion Banner

The companion banner appears in the top-right corner on desktop and complements the main video. You can replace it with your own creative, and if no banner is uploaded, Google will automatically generate one based on your YouTube channel’s content.

The banner requirements are the same as for the companion banner used in the YouTube Non-skippable format.

Direct Placements on Media Platforms

Direct placements on media platforms offer broader opportunities for using non-standard formats and special integrations. At the same time, they require a more customized approach: technical requirements can vary significantly from platform to platform, so creatives are often prepared specifically for the chosen website or ad placement.

Specifics of Working with Direct Placements

Unlike programmatic platforms, direct placements often require direct communication with the platform’s technical specialists. This allows you to receive more detailed recommendations on creative optimization, but it also demands more time for coordination and approvals.

Variety of Formats and Sizes

Each media platform may offer its own, sometimes unique, advertising formats. The most common include:

• Non-standard banners: interactive, expandable, pop-up, and other dynamic formats
• Special integrations: page takeovers, custom widgets, and other tailored solutions
• Native formats: branded articles, sponsored content, and editorial materials featuring integrated brand messaging

Working with Different Direct Platforms

When working with direct placements, it’s important to follow several essential practices:

• Request up-to-date technical specifications directly from the platform’s representatives — requirements can vary and are frequently updated.
• Submit materials in advance to allow time for possible adjustments or clarifications.
• Test creatives across different devices and browsers to avoid display issues.
• Agree on the schedule for updating and replacing creatives throughout the campaign to ensure technical changes don’t disrupt its workflow.

Step-by-Step Material Review Before Submission

1. Checking Dimensions and Formats
   • Do the creatives match the recommended sizes for the selected placements?
   • Is the correct file format used?
   • Does the file size stay within the maximum limit?
2. Quality Assurance
   • Is the image resolution sufficient?
   • Are fonts and colors displayed correctly?
   • Is the animation or video speed properly optimized?
3. Content Review
   • Does the text comply with platform restrictions?
   • Does the creative avoid any prohibited elements?
   • Are calls-to-action and logos placed correctly?
4. Technical Validation
   • Are UTM tags properly implemented for tracking?
   • Do all links and buttons work correctly?

What to Do If Your Materials Don’t Meet the Requirements

If creatives fail a technical check or get rejected, it’s important to act quickly. The most effective steps include:

• Make adjustments promptly. Ensure your team can edit materials quickly so the campaign launch is not delayed.
• Use backup options. Temporarily replace the main creatives with alternative versions you’ve prepared in advance.
• Consult with the platform’s technical specialists. They can often propose optimal solutions or point out the exact reasons for rejection.
• Reconsider your placement strategy. If the restrictions are too strict or the format is unsuitable, it may be worth exploring other advertising platforms or placement types.

Tools for Creative Optimization

To streamline the preparation process and speed up creative production, you can use the following tools:

• Adobe Creative Cloud — a professional suite for creating and thoroughly editing visual materials.
• Canva — quick creative development using ready-made templates without the need for complex software.
• Google Web Designer — a convenient tool for building HTML5 banners.
• TinyPNG / TinyJPG — image compression tools that reduce file size without noticeable quality loss.

Summary of Key Technical Requirements

Meeting technical requirements is not a formality — it is one of the key factors that determine the effectiveness of advertising campaigns. Well-prepared creatives help avoid delays, ensure proper ad delivery, and directly influence the return on advertising investment.

Regardless of the platform, advertising materials should meet the following criteria:

• optimal file size while maintaining high quality;
• correct aspect ratios and resolution for each format;
• consistent display across different devices;
• compliance with text and content restrictions;
• full alignment with the platform’s technical standards.

When planning a campaign, it is important to allocate sufficient time for:

FAQ

How much time should be allocated for preparing materials that meet all technical requirements?

The minimum recommended timeframe is 5–7 business days, but for complex formats and non-standard placements, it’s best to plan up to 14 days.

How do technical requirements vary depending on the type of placement?

Technical requirements depend not only on the platform but also on the buying method. For example, in programmatic (DV360), tracking pixel support, strict file size limits, and adherence to IAB standards are important. In Meta Ads, the focus is on adaptability and compliance with content policies. Direct placements often have individual specifications — non-standard sizes, unique integrations, or formatting requirements.

What are the most common reasons for ad rejection on Meta Ads?

Most materials are rejected due to exceeding the text limit on images (more than 20%), using prohibited content categories, or a mismatch between the ad offer and the landing page.

How should adaptive banners be prepared for different screen sizes?

Follow the “keep the most important elements in the center” principle, ensure text readability on smaller screens, and test display performance across different devices.

Can the same creatives be used for Meta Ads and DV360?

It’s possible, but adaptation is usually required to meet the specific requirements of each platform, especially regarding sizes and text limitations.
