If you’re spending real money on paid media and you’re not happy with your results, you’ve probably thought about making a change. The question most people ask is: should I hire a different agency, or should I hire a consultant? They’re not the same thing. And the difference matters more than most people realize. After spending 15 years inside big agencies including MediaCom, Starcom and more while managing multimillion-dollar accounts and leading teams across paid search and paid social, I left to build Zeller Media as a consultancy. Not because agencies are inherently bad. Because the agency model has structural problems that most clients never see until they’ve already wasted a year and a significant chunk of budget. Here’s the honest breakdown of how each model works, when each makes sense, and why the distinction matters for your business.
How Agencies Actually Work
The typical agency structure looks like this: you talk to a salesperson during the pitch. After you sign, you get handed to an account manager. The account manager coordinates between you and the “media team” — which is usually a mix of junior buyers, analysts, and maybe a strategist who oversees multiple accounts. Your actual campaigns are being managed by someone you’ve never met, who is juggling 8 to 15 other clients simultaneously. This isn’t cynicism. This is how agencies are built. They scale by adding clients, not by adding senior talent for each client. The economics of the agency model require leverage — a small number of experienced people supervising a large number of junior people doing the execution. For very large brands with $500K+ monthly budgets and complex multi-channel needs, this model can work. You need the headcount. You need the layers of specialization. You need media planners, creative teams, analytics departments, and platform specialists working in concert. But for mid-market businesses spending $10K to $100K per month on ads? The agency model often means you’re paying for the overhead of that structure while getting managed by the least experienced person on the team.
Most agency clients don’t realize that the person who sold them is not the person managing them.
How a Paid Media Consultant Works
A paid media consultant is the operator. No layers. No handoffs. No account manager who needs to “check with the team.” When you hire a consultant, the person you talk to in the sales conversation is the same person inside your Google Ads account adjusting bids, pulling search query reports, reviewing creative performance, pacing budget, and flagging issues before they become problems. The consultant model trades breadth for depth. You don’t get a 30-person team. You get one senior operator who knows the platforms deeply, has direct accountability for results, and communicates with you without filtering through three layers of project management. At Zeller Media, that’s exactly how it works. I’m inside client accounts every day. I build the dashboards. I run the strategy calls. I do the optimization work. Every recommendation comes from the person who actually sees the data — not someone interpreting a summary from someone else. The consultant model works because accountability is direct. There’s nowhere to hide.
The Structural Problem With Most Agencies
The agency incentive structure creates a specific set of problems that most clients experience but can’t always name. First, agencies are incentivized to retain clients, not necessarily to push them. If your account is stable and the client isn’t complaining, the agency has no structural reason to rock the boat by recommending aggressive changes, testing new strategies, or challenging the status quo. Stability is good for agency retention metrics. It’s not always good for your growth. Second, the people managing your campaigns often lack the experience to make judgment calls. When a junior buyer sees a bid strategy in learning phase, they might not know whether to wait it out or intervene. When a match type is leaking budget into irrelevant searches, they might not catch it for weeks because they’re reviewing search queries on a monthly cycle instead of a weekly one. When a Performance Max campaign starts cannibalizing branded search traffic, they might not have the context to diagnose it. Third, agencies often separate strategy from execution. The strategist who builds the plan doesn’t manage the campaigns. The buyer who manages the campaigns doesn’t see the full picture. This creates communication gaps where insights get lost, context gets diluted, and decisions get made without complete information.
Agencies optimize for scalability. Consultants optimize for performance. Both are valid. But they serve different needs.
When You Should Hire an Agency
Be honest about this: some businesses genuinely need an agency. If you’re spending $500K+ per month across multiple channels and need dedicated specialists for search, social, display, video, and programmatic — an agency is probably the right call. If you need integrated creative production alongside media buying, you need more headcount than one person can provide. If you’re a large organization with complex approval processes and multiple stakeholders, the agency’s project management infrastructure has value. The key is hiring a good agency. Look for one where the people managing your account have real experience, where strategy and execution aren’t siloed, and where reporting focuses on business outcomes, not vanity metrics. They exist. They’re just not the majority.
When You Should Hire a Consultant
A consultant is the right choice when you need senior-level expertise without the overhead. That typically looks like mid-market businesses spending $10K to $150K per month on ads across paid search and paid social. Businesses that have been burned by agencies and want direct accountability. Startups that need a fractional CMO-level operator who can build the system from scratch. Companies where the founder or marketing lead wants to talk directly to the person doing the work. The consultant model also works well for audits. If you’re not sure whether your current setup is working, you don’t need a full agency engagement. You need someone to open the account, tell you the truth, and give you a plan. That’s a consultant’s job.
If you want polished presentations, hire an agency. If you want growth, hire an operator.
What to Ask Before You Hire Either
Whether you’re evaluating an agency or a consultant, ask these questions: Who will actually be inside my ad account on a daily basis? What is their experience level? How do you handle budget pacing, and how often is it reviewed? Do you pull search query reports, and how frequently? How do you evaluate bid strategy performance? What does your monthly reporting include, and does it connect ad spend to actual business outcomes? How do you handle tracking audits and conversion validation? What’s your approach to creative testing and refresh cycles? The answers will tell you everything you need to know. If the responses are vague or generic, keep looking. If they’re specific, operational, and demonstrate that someone is actually inside the platform doing the work, you’ve probably found a good fit.
Why I Built Zeller Media as a Consultancy
I spent 15 years in the agency world. I saw how the sausage gets made. I saw brilliant strategists hand off plans to junior buyers who didn’t understand them. I saw clients pay premium retainers for management that amounted to monthly screenshots and a 30-minute call. I saw accounts degrade slowly because nobody was doing the foundational work — the search query reporting, the pacing discipline, the tracking audits — that separates real management from maintenance. I built Zeller Media to be the opposite of that. One operator. Direct accountability. Hands-on management. Custom dashboards built around the numbers that actually matter. Candid calls where I tell you what’s performing, what’s not, what I’m changing, and why. 35+ brands across finance, healthcare, real estate, ecommerce, hospitality, and more. Same obsession with results every time. If you’re tired of layers and want someone who’ll actually tell you the truth about your ad accounts, let’s talk.
The best consultant is the one who makes you wonder why you ever hired an agency.
