Why OLV Advertising Still Matters for Brand Growth

Online video (OLV) ads appear on websites, mobile apps, and video players outside of social media and streaming TV. They give businesses another way to reach potential customers while showing their products, services, or brand in action. Advertisers can choose who sees their ads, try different video formats, and track performance to see what’s working.

Key Takeaways

• Online video advertising continues to grow. IAB estimates U.S. spending will reach $20.7 billion in 2026, a 10% increase.
• OLV gives advertisers another way to reach people as they browse websites, watch videos, or look into products and services online.
• Rather than relying on OLV alone, businesses can use it alongside connected TV (CTV), social media, display ads, and search campaigns.
• On mobile, viewers may scroll past a video in seconds. Show your brand early and include captions for anyone watching without sound.
• Keep an eye on how often people see your ads and where they’re appearing. Too much repetition or the wrong placement can waste your budget.
• Video views only tell part of the story. Look at how many people you’re reaching, how much of the video they’re watching, and whether they’re visiting your website or becoming more familiar with your brand.

Video That Works Where Your Audience Already Is

Connected TV and social video dominate most video planning meetings, and some advertisers are paying for CTV growth by cutting online video. In IAB’s 2026 research, 36% of buyers who increased their CTV spend said that some of that money would come from OLV.

So does online video still deserve a line in the plan?

Yes, with a condition. OLV spend is still growing, and it reaches people at times the TV screen can’t, like checking the news on a phone at lunch.

The condition is that it is planned on purpose rather than renewed out of habit.

Version2’s Online Video channel pairs the reach of video with the targeting and optimization of programmatic buying. The sections below cover where OLV fits, what makes the creative work, and how to tell whether it’s paying off.

What Is OLV Advertising, and How Is It Different From CTV and Social Video?

OLV ads are the videos people come across while browsing websites or watching content online. You’ll find them on news, sports, and entertainment sites, as well as platforms like YouTube. They can appear on a phone, tablet, or computer. CTV ads, on the other hand, appear on television screens through streaming services, while social video ads show up as people scroll through their feeds.

OLV catches people while they are actively browsing and researching. Each channel covers a different moment in the day.

Within OLV, in-stream ads play before, during, or after video content. Outstream ads run in places with no video player, such as the middle of an article.

A word of caution on definitions. Industry research doesn’t always draw these lines in the same place.

IABs spend reports, for example, count YouTube as social video. Before comparing budgets or benchmarks from different partners, check which definition each one uses.

Why Does OLV Still Matter When Budgets Are Shifting?

OLV spend is still rising. IAB projects U.S. online video ad spend will grow 10% to $20.7 billion in 2026, within a digital video market expected to reach $81.9 billion.

With some buyers moving OLV dollars into CTV, the better question is where OLV fits in a plan, not whether to drop it.

The 2026 IAB Digital Video Ad Spend & Strategy Report also projects that digital video will account for 61% of total U.S. TV and video ad spend this year, the first time it has surpassed 60%.

There’s a gap in that $20.7 billion figure. IAB counts web and app publishers and excludes YouTube, so under Version2’s broader definition, the channel is larger.

How much larger, the report doesn’t say, and we haven’t found a public source that breaks it out.

Growth of 10% is steady, not dramatic. For most brands, OLV’s job is to carry the brand message into the hours people spend on their phones and laptops, a job CTV can’t do from the living room.

How Does OLV Build Brand Awareness, Engagement, and Consideration?

OLV combines sight, sound, and motion with programmatic precision. A campaign can run across thousands of publisher sites and apps, narrow delivery using audience data and page context, and use a different format at each stage, with pre-roll for awareness and outstream beside related articles for consideration.

What OLV gives a brand:

• Reach across news, entertainment, sports, and specialist publishers on desktop, tablet, and mobile.
• Targeting is built on first-party customer data, third-party data inside a DSP, page context, demographics, behavior, and retargeting.
• A choice of in-stream, out-stream, skippable, non-skippable, and six-second bumper spots.
• Reporting in real time, so a campaign can be adjusted while it runs.

Targeting carries more weight with buyers than it did a year ago. In IAB’s 2026 survey of 360 video ad decision-makers, targeting became the top factor in deciding where TV and video budgets go, chosen by 49% of buyers, up from 39% in 2025.

That works in OLV’s favor, since programmatic targeting is where it is strongest.

How Does OLV Work Alongside CTV, Social Video, Display, and Search?

OLV connects the other channels. CTV earns attention on the largest screen, social video reaches people in their feeds, and OLV carries the same message to people reading and researching across the open web.

Display and search, then pick up the interest the video generates, as seen in site visits and searches for the brand name.

If your plan already leans heavily on CTV, this section matters most.

Extending CTV Reach to Mobile and Desktop

Someone who sees a brand on the TV at night may be reading a publisher’s site on their phone at 7 a.m. OLV puts the same creativity in front of them there.

Reinforcing Social Video Outside the Feed

Social video stays inside the platforms. OLV reaches the same people on the news sites, apps, and video platforms they visit outside their feeds, which broadens the audience and keeps a campaign from depending on a single platform’s algorithm.

Feeding Display Retargeting and Branded Search

People who have seen the video recognize the brand when a display ad or a search result appears later. For more on planning these handoffs between channels, see Cross-Channel Campaign Management: Connecting the Dots Across the Customer Journey.

What Makes Online Video Creative Work on Mobile?

Mobile OLV creative has a few seconds to land, and it often plays with the sound off. The brand and the main message belong at the start, captions should carry the story without audio, and the framing has to be read on a small screen.

The industry counts a video ad as viewable after two continuous seconds.

That threshold comes from the Media Rating Council’s Viewable Ad Impression Measurement Guidelines: at least 50% of the ad’s pixels must be in view for two consecutive seconds of playback. Two seconds means the viewer had a chance to see the ad.

Whether they kept watching is a separate question, answered by completion rate.

Practical guidelines for mobile OLV creative:

• Show the brand or product in the first frames.
• Add captions and on-screen text.
• Cut vertical or square versions where the inventory allows.
• Keep to one message per spot.
• End with a simple next step.

How Do Frequency Controls and Brand-Safe Placements Protect Results?

Reach without controls wastes money. Frequency caps prevent the same person from seeing an ad too often, which can start to annoy them, and brand-safety and suitability settings keep video away from content the brand would not want to appear next to.

Running OLV across multiple DSPs adds a practical step, since each DSP needs its own pixels on the advertiser’s website. Version2’s ORION pixel container deploys the third-party pixels from each DSP through a single container, so they fire on-site without separate installations.

Which Metrics Show Whether OLV Advertising Is Working?

Measure OLV in layers. Reach and frequency show how many people saw the ad and how often they saw it.

Viewability shows whether they had the chance to watch, and completion rate shows whether they did. Brand lift shows movement in awareness or consideration.

Website activity and conversions show what people did afterward.

The layers explain each other. A high completion rate with no change in site visits usually points to a creative or targeting problem.

Strong conversions on low reach can mean the campaign is mostly finding people who were going to buy anyway, which looks efficient in a report and does little for brand growth.

Frequently Asked Questions

What does OLV mean in advertising?

OLV stands for online video. It means video ads served on websites, apps, and video platforms across desktop, tablet, and mobile, including pre-roll, mid-roll, and outstream placements.

Brands use OLV to build awareness and consideration by putting their message in motion on the sites and apps people already use.

What is the difference between OLV and CTV?

CTV ads run on television screens through streaming services and smart TV devices, usually during long-form programming. OLV ads run on computers, tablets, and phones within publisher sites, apps, and video platforms.

CTV suits lean-back viewing, while OLV reaches people as they browse, so the two channels work well together.

Are YouTube ads considered OLV?

Version2 includes YouTube in online video, alongside news, entertainment, and sports publishers. Definitions vary across the industry, though, and IAB spends research counts YouTube as social video.

Check which definition a partner or report uses before comparing budgets or benchmarks to ensure the numbers line up.

What counts as a viewable video ad impression?

Under Media Rating Council guidelines, a video ad is viewable when at least 50% of its pixels are on screen for two continuous seconds of playback. That confirms the ad had a chance to be seen.

Completion rate and brand lift show whether viewers actually paid attention.

How do you measure the success of an OLV campaign?

Match the metric to the goal. Reach, frequency, and viewability measure awareness.

Video completion rate measures engagement. Brand lift studies measure consideration.

Website visits, conversions, and cost per acquisition measure action. Looking at all of them together shows where online video is pulling its weight.

How often should someone see the same online video ad?

There is no single right number. It depends on the campaign goal, the length of the creative, and how many channels carry the same message.

Falling completion rates and rising cost per result often mean viewers are tired of the ad. Capping frequency across partners keeps exposure even.

Put Online Video Back to Work

Go back to the 36% of buyers paying for CTV growth out of their OLV budgets. Some of them will be right.

If their audience lives on the TV screen, the money belongs there. The rest may discover that the people they stopped reaching on phones and laptops were the ones who would have searched for their brand next.
