Video Ad ROI: 40% of Marketers Struggle in 2026

Despite a projected 12% growth in US digital video ad spend to reach $75 billion in 2026, a significant 40% of marketers still struggle to accurately measure the return on investment (ROI) for their video campaigns. This inability to connect video spend directly to business outcomes creates a substantial blind spot for budget allocation and strategic planning. How can marketers move beyond vanity metrics and truly understand their video advertising impact?

The Disconnect: 40% of Marketers Struggle with Video ROI

The sheer volume of investment in video advertising suggests a belief in its power, yet the persistent struggle to measure its ROI, as highlighted by a recent eMarketer report, is a fundamental problem. This isn’t just about understanding clicks or views. It’s about connecting video exposure to tangible business results, whether that’s a sale, a lead, or a specific brand action. Many marketers are still too focused on top-of-funnel metrics like impressions and video completion rates. While these provide some indication of engagement, they don’t tell the whole story of how video contributes to the bottom line. The challenge lies in attributing specific conversions to video touchpoints, especially in a complex, multi-channel customer journey. Without a clear line of sight, budgets can be misallocated, and effective campaigns might be undervalued, while underperforming ones continue to consume resources.

Attribution Models: Moving Beyond Last-Click

A recent IAB report indicates that only 25% of advertisers use advanced attribution models for video campaigns, with a majority still relying on last-click or first-click models. This oversimplification misrepresents video’s role, particularly its strength in driving awareness and consideration earlier in the buying cycle. Video often acts as a powerful introducer or persuader, influencing decisions long before the final conversion click. Consider a consumer who sees a compelling video ad for a product, researches it later, and then converts through a search ad. A last-click model would credit the search ad entirely, ignoring the foundational impact of the video. Marketers need to adopt models like linear, time decay, or position-based attribution that distribute credit across multiple touchpoints. Even better, data-driven attribution models, available in platforms like Google Ads and Meta Business Help Center, use machine learning to assign credit based on actual user behavior, providing a more nuanced understanding of video’s contribution. This shift is not merely academic. It directly impacts how much budget video receives and what kind of creative is prioritized.

The Power of Incremental Lift: 15% of Ad Spend Wasted Without It

A Nielsen study from last year suggested that up to 15% of ad spend across all channels, including video, could be wasted due to a lack of understanding of incremental lift. This means marketers are often paying for conversions that would have happened anyway, even without the video ad. Measuring incremental lift involves isolating the true impact of a video campaign by comparing the behavior of an exposed group to a control group that did not see the ad. This requires careful experimental design, such as geo-testing or holdout groups. For example, running a video campaign in Atlanta’s Midtown district while holding out a similar demographic in Buckhead, then comparing sales data, can reveal the true incremental impact. Without this kind of rigorous testing, marketers are essentially guessing at the actual value video brings. It’s a more complex approach than simply looking at post-campaign metrics, but it provides the most accurate picture of ROI. My experience tells me that many companies avoid this because it takes more upfront planning and a willingness to “sacrifice” a small portion of their audience for the sake of data, but the insights gained are invaluable for future campaigns. This approach aligns with the need for better Programmatic Video ROI to avoid wasted spend.

Beyond Clicks and Views: Engagement Metrics that Matter

While traditional metrics like views and clicks are easily accessible, they often fail to capture the qualitative impact of video. A Statista report on video ad spend by format highlighted the growing investment in interactive video, yet many measurement strategies haven’t caught up. We need to look at metrics that indicate deeper engagement and intent. This includes tracking interactions within the video itself, such as clicks on in-video calls to action, time spent on specific product segments within a longer video, or even post-view survey responses. Analyzing qualitative data, like comments on social video ads, can also provide rich insights into brand perception and message resonance. For instance, if a video for a new software product consistently generates questions about a specific feature, that’s a strong signal of interest that a simple view count would miss. Tools that offer heatmaps for video engagement, showing where viewers pause, rewind, or drop off, are far more useful than a generic completion rate. These granular insights allow for iterative improvements to creative and targeting, directly impacting future campaign effectiveness.

The Conventional Wisdom I Disagree With: “Short-form video is always better for ROI.”

There’s a pervasive belief that shorter video ads inherently deliver better ROI because they have higher completion rates and are less likely to be skipped. While short-form video certainly has its place, particularly for awareness and quick calls to action on platforms like YouTube Shorts or TikTok for Business, equating brevity with superior ROI across the board is a misguided oversimplification. For complex products or services, a longer, more detailed video can be far more effective in educating potential customers and building trust. The key isn’t length. It’s relevance and engagement. A 60-second explainer video that genuinely answers a customer’s questions and demonstrates value will likely generate higher quality leads and better conversions than a flashy 15-second spot that leaves them confused. The “attention span is shrinking” narrative often pushes marketers to create content that is too superficial to truly persuade. We should be optimizing for effective attention, not just minimal attention. The ROI lies in providing enough information to move the viewer further down the funnel, whatever length that requires. Testing different video lengths for specific campaign goals and audience segments is the only way to truly determine which format delivers the best return.

To truly master video ROI, marketers must move beyond surface-level metrics and embrace sophisticated attribution, incremental lift measurement, and a deeper understanding of engagement. This strategic shift ensures every dollar spent on video contributes meaningfully to business growth, not just to view counts.
