What is a Marketing Consultant, and why should you hire one?

Hiring a marketing consultant can feel like a leap of faith—will they actually make a difference, or will they just throw generic advice at you? If you’ve ever wondered whether it’s worth it, you’re not alone. Many business owners hesitate, but those who hire the right consultant often see real growth, better positioning, and more streamlined marketing efforts.

As a marketing consultant and fractional marketing manager, I’ve helped businesses like yours cut through the noise and focus on what actually works. Here’s what a marketing consultant does, why businesses hire them, and how they can transform your marketing strategy.

What does a marketing consultant actually do?

A marketing consultant helps businesses figure out what’s working, what’s not, and how to attract more customers. They create a strategy tailored to your brand, analyze data, and adjust campaigns to get better results. Some consultants stop at strategy, but others (like me) also handle execution—acting as a Fractional Marketing Manager to oversee implementation, manage teams, and ensure long-term success.

Unlike big agencies with standard solutions, consultants offer hands-on, customized guidance. Whether you need to revamp your website, improve your messaging, or finally crack paid ads, they provide direct, customized advice.

A Reddit discussion on why businesses hire marketing consultants highlighted that many companies struggle to develop a structured, well-researched marketing strategy. They either lack experience or spend too much time on trial and error, leading to wasted budgets. This aligns with research showing that companies with a documented marketing strategy are 313% more likely to report success than those without one (HubSpot).

Why do businesses hire marketing consultants?

From reading real stories from business owners, it’s clear that hiring a marketing consultant often comes down to three things:

✅ They don’t have time to do everything themselves

One of the biggest reasons businesses bring in a consultant is that marketing takes time—time they’d rather spend running their company. A marketing consultant helps cut through the noise and focus on what actually works.

✅ Their growth has stalled

Many businesses reach a point where their DIY marketing stops working. Maybe Facebook ads that once brought leads are suddenly burning cash. Or sales have gone down, and they don’t know why. A consultant brings an outsider’s perspective and experience from other industries to spot blind spots and new opportunities.

✅ They can’t afford a full-time CMO

A full-time marketing hire—especially someone with experience—can be expensive. A marketing consultant gives you access to high-level expertise without the long-term salary commitment. Some businesses even keep consultants on an ongoing basis as a Fractional Marketing Manager, where they act as a part-time CMO, managing teams and driving results over months or years.

In fact, companies that outsource marketing efforts often see a 25-30% reduction in costs compared to maintaining an in-house team (HubSpot).

Common myths about hiring a marketing consultant

🚫 “They just give advice and leave”

Not always. While some consultants focus only on strategy, others (like me) also execute the plan—whether that means running campaigns, managing your team, or optimizing your website.

🚫 “I can just Google everything” or “I can do everything with AI”

Sure, you can Google anything, but the real challenge is knowing what’s worth doing. A marketing consultant helps you skip trial and error, saving you money and time. AI can help automate tasks, but strategy and creative decision-making still require human input and expertise.

🚫 “Marketing is just social media”

Marketing isn’t just posting on Instagram. It’s understanding who your customers are, how they buy, and what messages actually convert them—across ads, emails, SEO, branding, and more. A marketing strategist helps connect the dots.

Is hiring a consultant worth it?

If you’re spending money on marketing but not seeing results, the right consultant can change that. They help businesses avoid costly mistakes, refine their messaging, and build marketing systems that work long-term.
