Is Your Ad Agency Failing You? 4 Questions Every Brand Must Ask in 2026

The digital advertising landscape has changed radically over the past two years, but many marketing agencies are still using an outdated playbook.

The newly released Global State of PPC 2026 Report, which surveyed 1,306 advertising professionals, exposes some uncomfortable truths about the industry. The data reveals exactly where agencies are falling short and what the top-performing teams are doing differently.

If you are paying an agency to manage your digital ads, here are the four questions you need to ask them right now to ensure you aren't wasting your budget.

1. Can you actually prove my ROI?

It might shock you to learn that the number one reason brands are unhappy with their current ad agency is a failure to properly measure ROI. A staggering 19% of clients report dissatisfaction with their agency's ability to track what actually matters.

Why is this happening? Managing PPC is getting harder, with 53% of practitioners citing less accurate conversion measurement—caused by privacy updates and cookie loss—as a primary hurdle. Many agencies are still relying on basic, outdated pixel tracking. To succeed in 2026, you need a commercial partner who moves beyond vanity metrics and makes advanced measurement (like offline conversion imports and profit tracking) a core part of their service,.

2. Are you "taming the machine," or just pushing buttons?

Google’s automated campaign type, Performance Max (PMax), is everywhere. But here is the industry's dirty little secret: 48% of PPC professionals complain about the lack of granular control with PMax, and 41% are frustrated by the "black box" lack of transparency.

If your agency simply turns on Google's automated campaigns and walks away, they aren't adding value. The best agencies don't just blindly trust the algorithm; they know how to regain control. Interestingly, classic, high-control tools like Exact Match keywords and Standard Shopping campaigns still yield some of the highest satisfaction rates among top-tier practitioners. Make sure your agency is actively steering the strategy, not just letting the platforms spend your money.

3. How are you fixing our product feed? (For E-commerce Brands)

If you are an e-commerce brand, your product feed is either your greatest asset or your silent killer. A massive 54% of practitioners managing Google Shopping cite feed errors and missing data as their absolute biggest challenge,.

AI-driven ad algorithms rely entirely on your product data to match your items with consumer queries. If your current agency is only tweaking bids and ignoring the health of your product feed, your ad spend is bleeding out,. The foundation of a profitable e-commerce campaign in 2026 is resolving feed errors and optimizing product attributes—if your agency isn't doing this, it's time to look elsewhere.

4. Why am I still paying you by the hour?

Artificial Intelligence has made ad management faster. In fact, agency teams managing over $1M a month in ad spend are now 20% more efficient than they were just two years ago. AI tools are saving practitioners up to five hours a week on repetitive tasks.

Yet, incredibly, 18% of agencies still price their ongoing management based on billable hours,. In the age of AI, hourly billing means you are paying your agency for their inefficiency,. You should be paying for outcomes, solutions, and strategy—not the amount of time it takes an agency to do a job that AI just made 20% faster.

The Bottom Line

The era of the "button-pusher" agency is over. Today, the real battle in digital advertising is fought outside the ad account: it's about business strategy, fixing data feeds, and flawless tracking.
