TV advertising remains one of the most powerful tools in a marketer’s arsenal. Whether you’re promoting a product, service, or show, a perfectly placed spot can drive real results. But here’s the catch: even the best creative and most strategic media plans can fall apart due to one small—but critical—breakdown in trafficking.

We see it happen all the time: a brilliant campaign derailed by a minor oversight. And once a spot doesn’t run as intended? You’re left playing catch-up, missing impressions, losing momentum, and wasting spend.

So, let’s break it down. Here are the top five reasons TV spots run incorrectly—and how to avoid them before they cost you time and money.

1. ISCI Confusion: When One Letter Makes All the Difference

TV spots are identified by ISCI codes, and these codes are often very similar. When you’re managing multiple versions across different regions or creative iterations, it’s all too easy to accidentally assign or upload the wrong one. Even a single digit off can result in the wrong ad airing—or nothing airing at all.

How to prevent it:
Use a clear and consistent naming convention, and double-check everything before distribution. Better yet, work with a trafficking partner who flags inconsistencies before they become problems.

2. Version Overload: So Many Spots, So Many Specs

Need a 29.5-second version for one network, a 28.7-second cut for another, and a tagged local version for a regional affiliate? You’re not alone. With versioning becoming more complex, it’s easy for one incorrect file to slip through or get rejected entirely.

How to prevent it:
Build a centralized version management system and assign clear approvals before release. And remember: precise specs matter. A spot that’s off by even 0.2 seconds can be rejected.

3. Creative Doesn’t Match the Media Plan

You’ve invested in a creative arc—bookends, rotations, local messaging. But if the media buy isn’t synced to the creative strategy (or vice versa), the wrong spot can end up in the wrong slot. And the story you planned to tell? It never quite comes together.

How to prevent it:
Align your trafficking and media teams early—and make traffic part of your strategy, not an afterthought. Seamless execution depends on collaboration.

4. Rushed or Missed QC

Deadlines are tight. Maybe someone skips a final QC, or assumes the file is good to go. But a simple error—a typo in the slate, bad audio, or an outdated super—can send your spot straight to the reject pile, or worse, to air with your brand looking sloppy.

How to prevent it:
Build in time for quality control, every time. Automated checks help, but nothing replaces trained human eyes.

5. Human Error Happens

It could be a missed email, a forgotten version, or sending out last month’s file. We’re all human, and mistakes happen, but in a high-stakes, high-visibility channel like TV, even one small error can have a big ripple effect.

How to prevent it:
Set up systems that catch errors before they go live. Partner with a trafficking team that specializes in spotting red flags before they cost you air time.
