‍What are Youtube Ad Specs?

Youtube ad specs are guidelines for creating ads on Youtube which include its format, resolution, size, length, aspect ratio and other aspects. These technical requirements ensure your ad is approved by Youtube and seen by its’s viewers.

Besides passing Youtube's strict guidelines, complying with these specs can also do the following:

Ensures your ad is presentable and polished for your viewers.
Helps to optimise your ad to generate leads and increase conversions.
Lets you analyse your ad's performance once it’s up and running.
Protects your brand's reputation as ads comply with Youtube regulations.

Youtube Skippable Video Ads

Skippable ads run before, during or after a video plays, making users almost always want to hit the 'skip ad' button! But don't let that detract you as an advertiser, skippable ads provide a tonne of leads if done properly.

This ad format lets viewers skip ads after 5 seconds, enabling them to go straight to the content. They're also cost-effective and target audiences based on an advertiser's preferred demographics, interests, and more.

Skippable Video Ads Specs

Video file format: Windows Media, AVI, ASF, Quicktime, MP4 or MPEG

Resolution: 640 pixels by 360 pixels

Aspect ratio: 16:9 or 4:3. We recommend 16:9 due to the growing trend of Youtube viewers transitioning to CTVs.

Min to max video length: at least 12 seconds. However there is no time limit.

Max file size: 1GB

Frame rate: 60fps

Video duration: 12 seconds to 3 minutes

Youtube companion image specs:

Skippable Ads Best Practises

Create a strong hook to immediately lure your target audience in. Your goal is to keep them watching even after 5 seconds.
Showcase your product or service's best attributes early in the video.
Stay within 30 seconds unless your ad involves storytelling elements that require a longer duration. Otherwise, viewers may quickly experience ad fatigue.

Youtube Non-skippable Video Ads

Non-skippable videos show up at the start of a video. These ad types are generally shorter as they're mandatory viewing, stopping viewers from leaving the video midway. In some cases, a video can host up to two ads.

Non-skippable ads are more cost effective than skippable ads and cannot be avoided. This means you can focus less on a compelling hook and more on the story's narrative.

Non-skippable Video Ad Specs

File type: AVI, ASF, Windows Media, Quicktime, MP4 or MPEG

Resolution: 640 pixels by 360 pixels or 480 pixels by 360 pixels recommended

Max file size: 1GB

Video length: 15 or 20 seconds for non-skippable; 20 seconds for long non-skippable

Video Duration: 15 or 20 seconds

Non-skippable Video Ad Best Practises

Unlike skippable ads, a strong hook isn't necessary here. Focus on the main content itself, like how your product solves a problem.
Keep it simple - your ad may be unavoidable but it shouldn't be a drag to watch.
Use easily understandable messaging and visuals - your audience must grasp the plot within 15-20 seconds.
‍

Youtube Bumper Ads

A Bumper ad is a non-skippable ad that shows at the end of a video, lasting a maximum of 6 seconds. Because of its short duration, your creative messaging has to be short and sweet. So, instead of trying to fit all product/service benefits, focus on the most compelling points and a call-to-action.

These ads are perfect for product launches or company's trying to improve their outreach. They also perform very well on mobile devices and are sold on a CPM (Cost per mille) basis, making them ideal for maximising impressions and brand awareness.

Bumper Ads Best Practises

As mentioned, use compelling visuals and copy. You want to make a statement within those 6 seconds.
Have one key message - don't try to cram too much in!
Keep the CTA straightforward - your audience shouldn't think about what to do next.
Keep your brand in focus by including a logo or product name.

Youtube Display Ads

Youtube display ads are either static or animated images that appear on a screen’s top right hand side, above your suggestions list. However, they can also be displayed below a user's youtube player on larger screens i.e. a connected TV.

Display ads can be compared to Single image ads on Facebook. Advertisers display one image along with a catchy headline, some copy and a clear CTA (call-to-action) button. The primary difference, however, is that Youtube viewers can watch videos uninterrupted while the display ad shows up.

Display Ads Best Practises

Experiment with animated static ads. Use motion, colour, transitions and other visuals to draw attention, albeit subtly.
Don't be disruptive by using overly flashy visuals.
Include a captivating headline that's highly engaging.

Youtube Overlay ad

An overlay ad is displayed as a semi-transparent banner at the bottom of a video. Users can click on its image or text box to be redirected off the website.

Overlay ads work because they don't detract from the main video. They're also positioned in the most visible area of a user's screen, and while small, their placement increases the chances of click throughs. And even if users don't click, it's visibility helps to at least gain impressions, boosting brand recognition.

However, the primary reason why it's the most used Youtube ad is because it's free. Yes, you heard that right! Your budget won’t be a factor in creating an overlay ad, and if you're feeling creative, go ahead and design one yourself!

Overlay Ad Best Practises

Ensure your brand is the star of the ad! Even if they don't click, you still want viewers to remember your brand.
Use an image that complements the video's topic. For example, if the video is about weightlifting, featuring premium protein powders for sale works.
Refrain on flashy visuals which can disrupt the video watching experience.

Trueview Video Discovery Ads

Video Discovery ads appear at the top of YouTube search results when users search for something related to the advertiser.

This ad type includes a video thumbnail image, a headline and short description, giving the viewer a preview of what's next when they click. They're also cost-effective as you don't pay for impressions - you only pay when a user clicks on your ad.

Video Discovery Ads Best Practises

As your video's thumbnail is the first to pop up on the search results page, make sure it's visually appealing and relevant to entice new viewers.
Optimise your description by including relevant keywords and keeping headlines under 25 characters and descriptions under 90 characters.
Feature tight shots and keep your core topic in the middle of the thumbnail.
Write copy that will make potential leads want to convert i.e. “Learn how to make the best mac and cheese in 2023”.
Use catchy visuals, such as logos or slogans to lure your target audience.‍

Youtube Sponsored Cards

A Sponsored card appears on a Youtube video, and is typically related to what the viewer is watching. It's ideal for advertisers to naturally plug products and services without trying to shoehorn them in. For example, a social media marketing tutorial video could use a Sponsored card featuring the latest social media tools.

When clicked, sponsored cards take viewers directly to the advertiser's landing page. Ads can be viewed on mobile and desktop devices, coming with additional features such as teaser text, headline, images and CTA buttons. Teaser texts are especially effective as you're already highly engaged with viewers at this point.

Youtube sponsored cards — Youtube Sponsored Card

Precise Targeting: Users watch videos based on their interests. With Youtube ads, you can target your audience based on their demographics, location, interests, and search history. Thus, your viewers will more likely be interested in your product or service.

Brand Recognition: Ad formats, like Overlay ads and Bumper ads, give a perfect opportunity to increase brand visibility on Youtube. Even if viewers don't click on your ads, its appearance will increase brand recognition.

Easily position your ads in the right places: Instead of advertising a random product on any video, use the Discovery ad and Sponsored Card ad formats to strategically place your ads in the right places. This ensures that they reach viewers who are actually interested in your product or service.
