David Zelenka – marketing strategy, not gut feeling

Man in an office explaining something to colleagues – David Zelenka

Marketing runs on gut feeling more often than we admit

A color gets picked because someone likes it. A channel gets added because competitors have one. The target audience is “women 25–45,” and nobody ever checked. When something fails, another channel gets added.

Without an answer to this, every campaign is a guess. And guessing costs money – just never on a single invoice.

How I do it differently

3 steps, no surprises

Each step is a separate decision. You can stop after the first one and you owe me nothing.

Initial consultation

30 minutes online. We go over where you are and where it hurts. You leave with a summary and a suggested next step – even if that step is “nothing for now.”

Diagnosis

60–90 minutes in depth. 5 questions every business needs to be able to answer. Usually the problem turns out to be somewhere other than expected.

Plan

A document you can actually work with: what to start, what to stop, and what to do differently. Plus what to measure – and what can't be measured.

Sound familiar?

If at least 2 of these ring true, we'll get along. The industry doesn't matter – online stores, services, and manufacturing, B2B as well as B2C.

The problemWhat I'll do about it

01You spend serious money on marketing, and when someone asks “what's actually working?” you don't have an answer you'd accept yourself.

We'll go through what can be measured and what can't. For the rest, I'll tell you what to base decisions on when the numbers aren't there.

02You have 3 vendors, and each one shows you that its channel works. But when you look at the whole picture, something doesn't add up.

I'll put the channels into one picture that shows what feeds into what – and what gets counted twice.

03Your last big decision was made in a meeting where people voted on which option they liked better.

You get 5 questions every business needs to be able to answer. Decisions are then made against them, not against taste.

04You keep adding things. You can't remember the last time you stopped doing something.

Part of the plan is a list of things you'll stop doing. It's usually the cheapest improvement there is.

Who it's not for: If you expect someone to guarantee numbers, or marketing to rescue a product that doesn't work – I'll tell you at the first meeting. Not after 3 months of work you've paid for. When not to call me

How it works

I don't promise numbers. I promise a system.

Working out what needs to be done is possible. Guaranteeing the result isn't – and anyone who does is lying.

Some things can't be measured.

Brand and SEO reach places your analytics will never show. That doesn't mean the effect isn't there. I'll tell you when it's fine to simply trust something.
