The reason for this is straightforward. Video ads are more engaging than static advertisements, so they tend to have higher CTRs and are more effective in driving conversions. Additionally, they allow advertisers to deliver more valuable information to their audiences. Short product demonstrations, “how to” instructions, customer testimonials — this and other content can be created in the format of video ads, helping advertisers show their expertise and gain trust. 

In this guide to digital video advertising, we will go through diverse video ad types and explore channels for launching such campaigns.

Types Of Video Ads To Pay Attention To

Firstly, let’s take a look at different types of video advertisements that are popular among both marketers and publishers.

Instream Ads

Example of the Instream Video Ad Format

Instream ads play within the already existing video content — most likely, you saw them on YouTube. They can be shown before the main video starts playing (pre-roll), during the video (middle-roll), and at the end of the clip (post-roll). Such ads can be skippable and non-skippable, but regardless of the selected option, more and more advertisers prioritize short video ads. According to Statista, spending on short-form videos is forecasted to reach almost $99.5 billion in 2024. 

Outstream Ads

Example of the Outstream Video Ad Format

Outstream ads appear within non-video environments. For instance, advertisements can be shown within the editorial content (between the paragraphs), and this format is especially popular on websites that have a lot of text: articles, studies, and so on. Alternatively,  ads can appear in the corner of the page and follow users while scrolling. Originally, outstream ads were available only for mobile devices, but now they can be seen on desktops, too.

Rewarded Ads

Example of the Rewarded Video Ad Format

Rewarded ads often become a part of the in-app content, and their concept is simple. A user opts in for an ad, watches a non-skippable clip, and gets a reward. This can be, for instance, virtual currency, extra life (in mobile games), or anything else app developers can offer within their product. Rewarded videos have high completion rates and are especially helpful for driving app installations. At the same time, web rewarded video ads are also entering the stage, becoming a more universal marketing tool. 

Interstitial Ads

Example of the Interstitial Video Ad Format

Interstitial videos are ads completely covering the screen of an app or a website. Usually shown during transitions between the parts of the main content (for example, game levels), they can often be skipped after some time. This way, they are less intrusive but rather effective in terms of driving engagement, which is beneficial both for publishers and advertisers. 

Channels For Launching Video Campaigns

Video advertisements are not an innovation in 2024, but their ecosystem is evolving continuously. With the growing popularity of streaming services, both advertisers and publishers get new opportunities. 

It is important to choose the relevant video distribution channels to get positive results for all sides of the media trading process: advertisers, publishers, and ad exchanges, or ad networks.

FAST TV, standing for free ad-supported streaming TV, works in a rather similar way as traditional TV, but over the Internet. The content is available for free, but users have to watch ads to access it. There are a lot of FAST streaming services offering both on-demand content and live channels, and many users prefer watching videos exactly in this way. For instance, in 2023, 57% of viewers favored FAST platforms (in the US). The reason for this is obvious — the content of FAST apps is free, while paid streaming services tend to increase their fees. 


The term CTV (connected TV) refers not only to smart TVs with Internet connection but also to other devices like gaming consoles or adapters (e.g. Roku). However, the video ads themselves are still shown on the TV screen and delivered via a streaming service or app. Adopting CTV advertising can be beneficial for marketers, as the number of CTV users keeps growing. For example, among millennials in the US, this number is expected to exceed $62.5 million by 2025. And in 2023, 88% of households (again, in the US) owned at least one Internet-connected TV device. One more fact to mention here is that CTV ad spending in video advertising is forecasted to reach almost $34.5 billion in 2024.

While CTV devices are devices connected to the Internet, OTT (over-the-top) is the method of delivering streaming content (for instance, services like Netflix or Amazon Prime Video). Thus, OTT content can be watched not only on connected TVs, but also on smartphones, laptops, and other devices. Therefore, OTT advertising is more flexible, although its meaning is pretty similar to CTV — delivering ads via streaming services.

What Should You Do As An Ad Exchange Owner?

Being an owner of an ad exchange implies ensuring efficiency for your SSP (a type of programmatic software for publishers to facilitate sales of their advertising impressions) and DSP (a type of programmatic software that allows an advertiser to buy advertising with the help of automation) partners — this is your way to drive stable media trading income. You need to provide publishers and advertisers with a diversity of ad formats and channels. At the same time, it is crucial to match DSP and SSP partners correctly, to guarantee relevant traffic.

Building such functionalities from scratch is usually expensive and time-consuming, but there is an alternative. The SmartHub white-label ad exchange is already equipped with online video advertising functionality.
