The Real Reason LinkedIn Ads Fail with Cody Duke
June 25, 2026
In the autopsy behind failed LinkedIn ad campaigns, one mistake shows up early - the campaign structure is weak. In this episode of LinkedIn AdWise, host Justin Rowe sits down with Cody Duke to unpack where LinkedIn budgets actually get wasted, why placement settings matter more than most teams realize, and how marketers can stop building strategies around only what they can track. Cody also shares why enterprise and federal marketing require a different playbook - one that’s built around mental availability, sales alignment, and knowing how the business you’re targeting actually buys services and products.
B2B marketers love to pin the blame on LinkedIn Ads, saying they’re too expensive. But in many cases, the real issue is not the cost of the platform. It is the way campaigns are planned, structured, measured, and connected to the business.
In this episode of LinkedIn AdWise, host Justin Rowe sits down with Cody Duke for a practical conversation on how LinkedIn budgets get wasted and what marketers should audit before they blame the channel.
What You'll Learn:
- Why LinkedIn Ads are often poorly structured
- Why placement settings should be one of the first things marketers audit
- How Audience Network can quietly drain LinkedIn budgets
- Why “peanut buttering” budget across too many campaigns weakens performance
- Why marketers should work big to small before touching ad-level optimization
- How to think about attribution without letting dashboards dictate the whole strategy
- How paid media can support sales, partnerships, and the wider business instead of acting like a standalone channel
Tune in for a practical conversation on fixing the structural problems behind LinkedIn ad performance before assuming the channel is the problem.

Episode Highlights
15:58 Attribution Should Support The Story, Not BE The Story
Cody and Justin talk about why B2B marketers need better attribution, but also need to be mindful about how they use it. LinkedIn often plays a role across a longer buying journey, especially when buyers do not click immediately. The goal is not to claim that LinkedIn closed the deal autonomously, but rather show where LinkedIn helped create awareness, influence accounts and directly support sales activity.
20:04 The Problem With Building Strategy Only Around What You Can Track
Justin points out a trap many smart companies fall into: they build marketing strategies based only on what they can prove in the dashboard. While that sounds responsible, it can lead to weak marketing. If teams only do what is easy to track, they may ignore wider, but equally important results such as brand awareness, trust and credibility. Cody suggests that the better approach is to build a strong strategy first, then figure out what can be measured.

22:44 Why Placement Settings Should Be The First Audit
Cody explains that one of the first things he checks in any LinkedIn account is whether spend is actually staying on LinkedIn or being pushed into Audience Network. If a campaign is meant to reach people on LinkedIn but most of the budget is being spent elsewhere, the campaign is already working against itself. Before marketers test new creative, change bids or rewrite copy, they need to make sure the money is going where they intended it to go.
24:34 The Structural Waste Hiding Inside LinkedIn Campaigns
Cody shares his “big to small” approach to campaign audits: instead of starting with small optimization tweaks, he looks at the bigger structure first. This would include the strategy, number of campaigns, how the budget is spread, audience size and whether the campaign setup matches the actual goal. A common mistake is spreading a limited budget across too many campaigns and then wondering why nothing has enough volume to work.
