40% of One Agency’s YouTube Budget Went to Music Videos. Nobody Knew

By Rich Knopke, Head of Sales, Nomology

We recently audited an agency’s in-house YouTube campaign for a travel client spending $50,000 a month. Forty percent of the budget, or $20,000 a month, was going to music content.

The agency had no idea.

Nobody had planned it that way. The client strategy didn’t call for it, and performance data hadn’t demonstrated that music was where the budget worked hardest. Over the course of a six-month campaign, the spend had accumulated there, one automated decision at a time, while the campaign continued hitting its delivery benchmarks.

That’s the quiet risk with YouTube. Buying YouTube and maximizing YouTube are two different things, and the gap between them rarely shows up in a standard performance report.

Why the gap matters more than ever

YouTube continues to command a growing share of viewers’ attention and advertisers’ consideration. According to Nielsen’s July 2026 Gauge report, YouTube accounted for a record 14.2% of all U.S. TV viewing that month, with viewing time up 6% from June.

At the same time, AI is changing how people discover and consume content, while privacy changes are creating new challenges for audience identification, targeting and measurement across the Open Web. As the advertising landscape shifts, YouTube becomes an increasingly important part of the media mix.

But greater investment in the platform makes it even more important to understand where the money is going and what it’s accomplishing. As automated buying handles more of the execution, agencies need the visibility and expertise to evaluate those decisions rather than simply accept the results.

And for independent agencies, the people who would catch these issues are often wearing multiple hats. Q4 campaigns are live, 2027 planning is underway and YouTube is one line in a much broader media plan. Even experienced in-house teams have limited time to give every platform the attention it deserves.

This isn’t an isolated finding. Of the 50 audits we’ve conducted this year through our Media DNA auditing tool, 48 uncovered some form of placement concentration or inefficiency that wasn’t an intentional part of the strategy. Across campaigns we’ve reviewed, we typically find 20–30% of YouTube spend going toward low-impact or misaligned placements, including instances of heavy concentration in music or news content.

What our audit revealed

Placement concentration wasn’t the only issue. The campaign ran almost entirely on non-skippable ad formats, limiting opportunities to understand how different audiences chose to engage with the advertiser’s message.

A more diversified format mix, including skippable TrueView ads, could provide additional engagement signals and audience insights to inform targeting and optimization.

The point isn’t that music is inherently the wrong place to spend. For some brands, it may be exactly the right choice. The point is that nobody at the agency could explain why the money was going there, whether that allocation made sense for the client or what opportunities the campaign might be missing elsewhere.

After reviewing the findings, the agency brought in Nomology to help refine its audience strategy, targeting, optimization and overall approach to YouTube.

While the campaign is still in its early stages, we’ve already reduced the share of spend going to music by 98%. By incorporating skippable ad formats, where viewers can choose whether to watch a 30-second ad through to completion, the agency is also gaining greater insight into who is watching its ads and how different audiences engage.

Early optimization has identified several behavioral audience segments performing better than those in the agency’s previous non-skippable campaign, including Family Movie and TV Fans, Arts and Entertainment Aficionados, Foodies and Nightlife Enthusiasts. These initial findings are helping the team understand which audiences are responding and where to focus future optimization.

4 questions to ask before deciding whether to manage YouTube in-house or bring in an expert

The audit raises a broader question for agencies: how do you know whether your current approach to YouTube is working as well as it could, and whether your internal team has the visibility, tools and time to make the most of it?

These four questions are a good place to start.

1. Audit where your budget is going.

Deep dive into where the budget is going. If one category accounts for a significant share of spend, ask whether that concentration was intentional. A large allocation isn’t automatically a problem, but nobody should be surprised by it.

2. Compare planned audiences with actual delivery.

Put the audience in your brief next to the audiences your campaign is reaching. Where do they align, and where do they differ? YouTube can provide valuable insights into both your campaign and your consumers, but only if you’re looking at the data and using it to inform decisions.

3. Examine your format mix.

Different ad formats offer different opportunities to learn. Non-skippable ads can deliver reach and completed views, but because viewers can’t skip them, completion alone tells you little about their willingness to engage with the message. Skippable formats can provide additional signals about viewer engagement and help inform audience optimization.

4. Ask what changed last month, and why.

Every meaningful optimization should have a rationale someone can explain. What changed, what prompted the decision and what did the team learn? If nobody can answer those questions, it’s time to look more closely at how the campaign is being managed.

When in-house works

Plenty of agencies run YouTube well on their own. The ones that do tend to have clear ownership of the channel, people who understand its targeting and buying options and a regular process for reviewing placements and acting on performance insights.

They also recognize that YouTube requires its own expertise. It’s not simply a matter of applying search tactics to video, pressing the easy button on Performance Max or launching a campaign and assuming the platform will take care of the rest.

Concentration isn’t always a mistake, either. A deliberate investment in a particular content category can be a smart strategy. What matters is that someone made the choice, understands why and continues to evaluate whether it’s working.

For agencies that don’t have the capacity or specialized expertise to do all of this in-house, the answer isn’t necessarily to build another team. It’s about finding the right balance between what agencies do in-house and where external expertise and technology can help them get more out of the platform.

Beyond delivery: is your YouTube strategy working hard enough?

YouTube has become too important to treat as just another line in the media plan. As viewing continues to grow and more advertising investment flows to the platform, agencies need to be confident that their approach to buying, targeting and optimizing YouTube is delivering the best possible results for their clients.

Hitting delivery benchmarks is a starting point, not proof that a campaign is working as hard as it could. Understanding where the budget is going, whether placements align with the strategy and how performance insights are informing optimization can reveal opportunities that standard reporting may miss.

For independent agencies in particular, having the right expertise and technology in place can make a meaningful difference without requiring more from already stretched internal teams.

If you haven’t taken a closer look at how your YouTube campaigns are being delivered and optimized, now is a good time to do so. Nomology’s Media DNA audit provides an independent look at campaign delivery, placements, targeting and efficiency, helping agencies identify opportunities to get more out of their YouTube investment.

Because YouTube is too important to leave its performance to assumptions.
