Video advertising has become one of the most effective ways for brands to connect with their target audience.
Most of us spend a good part of our day watching videos and because of that, video ads have a unique way of capturing attention, telling a story, and turning interest into action.
From our experience, the real difference-maker is not just using video, but choosing the right type of video ad for what you want to achieve. Not all video ads are created equal.
Some are better for getting your brand noticed, while others work best when the goal is to drive clicks, leads, or sales. Understanding how each format works helps you use video more intentionally and get better results.
Below are eight common types of video ads, how they work, and when it makes sense to use each one.
1. Pre-Roll Ads
Pre-roll ads are video ads that play before the main video content starts. These are commonly seen on YouTube and other video platforms.
They usually last between 5 to 30 seconds. Some are skippable after a few seconds, while others must be watched fully before the content plays.
Best use cases:
- Brand awareness
- Product launches
- Short, attention-grabbing messages.
Why it works:
Viewers are most attentive before their chosen video begins. This makes pre-roll ads effective for introducing a brand or message quickly. However, the first few seconds matter most, especially for skippable ads.
2. Mid-Roll Ads
Mid-roll ads appear during a video, similar to a commercial break on TV. These are common in longer videos such as tutorials, interviews, or live streams.
Because viewers are already engaged with the content, mid-roll ads often have higher completion rates than pre-roll ads.
Best use cases:
- Longer campaigns
- Story-driven ads
- Products that need brief explanation.
Why it works:
Viewers are less likely to leave mid-video, especially if they want to finish watching. This gives brands more time to deliver a message, as long as the ad does not feel too disruptive.

3. Post-Roll Ads
Post-roll ads play after the main video content ends. These ads are less intrusive but also tend to have lower engagement.
They work best when paired with a clear call to action.
Best use cases:
- Retargeting
- Calls to action like sign-ups or website visits
- Reinforcing brand messages.
Why it works:
Viewers who stay until the end are often more interested and attentive. Post-roll ads can gently guide them toward the next step without interrupting their experience.

In-Stream Ads
In-stream ads are video ads that play within video content across platforms, including YouTube, websites, and apps. This category includes pre-roll, mid-roll, and post-roll ads.
They can be skippable or non-skippable, depending on the platform and ad format.
Best use cases:
- Broad reach campaigns
- Awareness and consideration stages
- Retargeting viewers.
Why it works:
In-stream ads allow brands to reach users while they are already in a video-watching mindset. This increases message recall, especially when the ad matches the viewer’s interests.

YouTube Bumper Ads
YouTube bumper ads are short, non-skippable ads that last up to six seconds. They are designed for quick exposure rather than detailed messaging.
These ads work well as part of a larger campaign.
Best use cases:
- Brand recall
- Product reminders
- Supporting longer video ads.
Why it works:
Their short length forces brands to focus on one clear message. Studies show that bumper ads are effective at increasing brand awareness when used consistently.
Google Ads Video Ads
Google video ads allow advertisers to place video content across YouTube and Google’s partner network. These ads can appear in search results, on websites, or before and during videos.
Advertisers can target audiences based on interests, behavior, search intent, and demographics.
Best use cases:
- Performance-driven campaigns
- Lead generation
- Conversion-focused ads
Why it works:
Google Ads offers strong targeting and measurement tools. Brands can track views, click-through rates, conversions, and audience behavior, making optimization easier over time.
In-Feed Video Ads (Social Media)
In-feed video ads appear naturally within social media feeds on platforms like Facebook, Instagram, TikTok, and LinkedIn. These ads often blend with organic content and autoplay as users scroll.
Best use cases:
- Social engagement
- Mobile-first audiences
- Short, visually appealing content
Why it works:
In-feed ads feel less like traditional ads and more like native content. When done well, they encourage likes, comments, shares, and clicks without disrupting the user experience.

Native Ads
Native video ads match the look, feel, and placement of the platform where they appear. They are often embedded within articles, recommended content sections, or publisher websites.
The goal is to provide value rather than feel promotional.
Best use cases:
- Content marketing
- Thought leadership
- Trust-building campaigns
Why it works:
Native ads are less intrusive and often receive higher engagement. Since they align with surrounding content, users are more likely to watch and interact with them.

Native video ads generate higher engagement, with completion rates of 50% or more. They also produce better brand lift, with increases of up to 82%, and greater purchase intent, with increases of 18% or more.”

How to Choose the Right Video Ad Type for Your Goals
Choosing the right video ad format really comes down to being clear about your goal.
Audience behavior matters just as much. If your audience spends most of their time scrolling social feeds, short in-feed or bumper-style videos make sense. If they are actively watching longer content, in-stream or mid-roll ads give you more space to explain and connect.
For performance-focused campaigns, we usually lean toward Google video ads because the targeting and measurement are clearer.
No strategy gets it right on the first try. Testing different formats and paying attention to results like watch time, click-through rates, and conversions is what really sharpens your approach over time.
