6 YouTube ad formats to consider

Before we dive into YouTube video ad specs, it’s important to understand the different YouTube ad formats out there. Each YouTube ad format has unique benefits to different businesses, so let’s talk about them all!

1. Display ads

Display ads on YouTube are only available for desktop advertising. You can use images or animations in display ads, and they appear to the right of a video.

Use display ads if:

  • You want to boost brand awareness
  • You advertise to an audience that uses primarily desktops
  • You don’t need sound to adequately advertise your product (you can use sound, but it’ll only pay when a user clicks.)

2. Overlay ads

YouTube overlay ads are the ones that show up in the bottom 20% of your video. They appear like a banner, and you can use videos or images and text to advertise your product.

Use overlay ads if:

  • You want to boost brand awareness

You can also choose to launch a companion display ad with your overlay ad.

3. Skippable video ads

YouTube video ads, whether they’re skippable or non-skippable, are like a commercial, and they appear at the beginning, end, or in the middle of a video.

Skippable video ads are just what they sound like — commercials that users can skip if they choose after watching five seconds.

Use skippable video ads if:

  • You want to boost brand awareness
  • You want to show off your product or service with a video

4. Non-skippable video ads

Non-skippable video ads are the same format as skippable ones — they appear as a commercial at some point in a video.

The difference? Users have to watch the entire thing before continuing to watch their selected video.

Use non-skippable video ads if:

  • You want to boost brand awareness
  • You want to show off your product or service with a video

Keep in mind that non-skippable ads could cause users to become frustrated and abandon the video altogether.

5. Bumper ads

Bumper ads are short video ads that play before, during, or after a video. These ads are meant to be short and sweet and are six seconds or less.

Use bumper ads if:

  • You want to boost brand awareness

6. Sponsored cards

Sponsored cards are ads that appear over top of a video while it’s playing. They appear to the right side of a video, and you can use them to advertise products or services that you talk about in your video.

Use sponsored cards if:

  • You talk about numerous products in your video
  • Your main goal of the video is to sell products
  • You want to make it easy for users to purchase products you talk about

Why is it important to follow YouTube video ad specs?

Now that we’ve provided you with the specs for each YouTube ad format, you might be wondering why it’s important to follow them in the first place.

When you fail to follow YouTube ad specs, you could render your ads ineffective — making your YouTube ad campaign a waste of your marketing budget.

Here are a few issues that could occur if you don’t follow YouTube ad specs properly:

  • Your text could be cut off
  • Your images could appear grainy or blurry
  • Your visuals could become skewed
  • Your video ads might not play properly
  • Your video could be cut off
  • Your audience won’t see the best version of your advertisement
  • You might turn users off to your products and services, or business as a whole

Overall, an unprofessional ad that isn’t aesthetically pleasing can cause users to lose trust in your business. Lost trust means fewer sales, so it’s important to create that trust in as many ways as possible — and one of them is to create beautiful ads by following YouTube ad specs for each format.
