The most common mistakes in marketing (That we don’t talk about enough)

I’ve seen marketing teams with big budgets and brilliant strategies fall flat—not because they lacked resources, but because they fell into avoidable traps.
The funny thing? These mistakes aren’t made by junior teams. They happen at every level, from startups to enterprise giants.

Here are the mistakes I keep seeing (and honestly, I’ve made some of these myself):

1. Confusing Activity with Impact

It’s easy to feel productive when campaigns are running, content is going out, and dashboards are lighting up with metrics.

But are those activities moving the needle?

I’ve been in meetings where the slide deck was full of impressive numbers—website visits up, social engagement through the roof, MQLs growing. Yet, when we asked the simple question: “How did this affect revenue or pipeline velocity?”—silence.

The trap: Measuring what’s easy instead of what matters.
The fix: Shift the focus from “What did we do?” to “What did it achieve?” Marketing is not about activity; it’s about outcomes.

2. Treating Brand and Demand as Separate Silos

I’ve seen teams split into “brand people” and “demand people,” as if these are opposing forces.

They’re not.

Great brands fuel demand, and smart demand strategies strengthen the brand.
Brand creates the emotional connection; demand captures it. You can’t scale efficiently if you treat them like separate functions.

Imagine pouring water into a bucket full of holes. That’s demand without brand.
Now imagine having a pristine bucket but never turning on the tap. That’s brand without demand.

The fix: Integrate both. A strong brand reduces acquisition costs. A strong demand engine keeps the brand alive in the buyer’s mind. It’s a loop, not a line.

3. Chasing Every Channel, Mastering None

The fear of missing out is real in marketing.

“We should be on LinkedIn.”
“What about podcasts?”
“Let’s start a webinar series!”
“Why aren’t we on TikTok yet?”

I’ve seen teams stretch themselves so thin that they end up with mediocre performance across the board. Every channel demands a unique approach—you can’t copy-paste content and expect results.

The fix: Focus. Identify where your audience actually engages and double down. It’s better to dominate a few channels than to have a weak presence everywhere.

4. Ignoring the Buying Journey

Many campaigns are designed around funnels, not around how real people buy.

Newsflash: No one wakes up thinking, “I’m in the consideration stage today!”

Here’s the reality:

  • Buying decisions take time.
  • They involve multiple stakeholders.
  • And most of that journey happens without your brand in the room.

We’ve all seen this mistake:

  • A prospect downloads an eBook.
  • Within hours, they get an email: “Let’s book a demo!”
  • Prospect ghosts.

Why? Because the marketing didn’t respect the actual buying journey.

In real life, buying decisions (especially high-ticket ones) are messy and non-linear:

  • A mid-level manager shows interest, but the final sign-off sits with the CFO.
  • The “lead” from last quarter suddenly resurfaces six months later because their budget just got approved.
  • A potential buyer reads your content for months before ever filling out a form.

The trap: Treating every lead like they’re “sales-ready” just because they clicked a link.
The fix:

  • Map the real decision-making process: Who’s involved? What do they care about? What triggers movement?
  • Design for patience: Not every lead needs to be pushed down the funnel immediately. Sometimes, the best strategy is to stay visible, stay relevant, and let the timing play out.
  • Create content for every stage: Not just for capturing leads but for nurturing complex buying groups over long cycles.

The best marketing doesn’t rush the buyer.
It stays present while the buyer takes their own time to get ready.

5. Over-Reliance on Playbooks

Playbooks are great—until they aren’t.

What worked for one company, in one market, at one point in time, doesn’t automatically translate.

I’ve seen companies waste months trying to replicate a “proven” ABM strategy or content framework from another business, only to realize the audience, context, and timing are completely different.

The trap: Thinking there’s a universal formula for growth.
The fix: Use playbooks as inspiration, not instruction. The best marketers start with first principles: “What problem are we solving? What’s the simplest, most effective way to do it?”

The Common Thread?

It’s not about doing more.

It’s about thinking better.
More campaigns, more channels, more content won’t save a strategy built on shaky foundations.

The real competitive edge in marketing isn’t the latest tool or trend—it’s the ability to think critically, question assumptions, and focus on what truly drives growth.
