Marketing Consultant for Small Businesses: What They Do, What They Cost and How to Choose One

By Simple Marketing teamUpdated 15 Nov 20268 min read

Hiring a marketing consultant is a big call for owners of small businesses. Get it right and you gain a growth partner who pays for themselves. Get it wrong and you lose months of budget to reports full of “impressions” and “engagement” that never turn into customers.

Below, we’ll explain what a marketing consultant for small businesses actually does, how they compare with agencies and freelancers, how they charge, and the exact questions to ask before you sign anything. We’re not writing this from the sidelines either: we’re a Kilkenny-based team voted Best Business Development & Marketing Consultants (Leinster) at the Irish Enterprise Awards, and we’ve sat on both sides of this conversation many times.

What does a marketing consultant for small businesses do?

Put simply, a marketing consultant looks at your business from the outside, works out what’s stopping growth, and gives you a clear, prioritised plan. A good small business consultant typically covers five areas:

1. Diagnosis. Reviewing your website, ad accounts, Google Business Profile, reviews, competitors and sales process to find where customers are being lost.
2. Strategy. Defining your ideal customer, your offer, the right channels and a realistic budget.
3. Implementation or oversight. Setting up or managing campaigns on Google, Meta, LinkedIn or TikTok, landing pages, tracking, email and CRM.
4. Measurement. Tracking cost per lead, cost per sale and return on ad spend, and reporting in plain English.
5. Business development. Improving how enquiries are handled and converted: follow-up speed, sales scripts, automation and reactivation of old leads.

That last one gets missed a lot. A lot of “marketing” problems are really follow-up problems. Leads come in, but nobody calls them back quickly enough. A consultant who understands sales as well as marketing will spot this early.

Marketing consultant vs agency vs freelancer: which do you need?

	Marketing consultant	Digital marketing agency	Freelancer
Best for	Strategy, direction, senior expertise	Done-for-you execution across several channels	One defined task (e.g. a logo or a set of posts)
Who does the work	The consultant, or your team/partners under their guidance	A team of specialists	One person
Strengths	Big-picture thinking, objectivity, direct access to an expert	Capacity, range of skills, continuity	Lower cost, flexibility
Watch out for	Advice without execution	Being passed to junior staff; long contracts	Gaps in skills; single point of failure
Typical engagement	Audit, project or ongoing advisory	Monthly retainer	Per task or hourly

For many Irish small businesses, the sweet spot is a consultant-led agency: one dedicated point of contact who understands your business, backed by people who can actually run the ads, build the pages and set up the automation. That’s how we work. You deal with the same person every time, not a rotating account manager.

How much does a marketing consultant for small businesses cost?

Costs vary widely with experience, scope and whether execution is included, so be wary of any guide that quotes one “average price”. What you can compare is the pricing model:

• Hourly or day rate. Good for audits, workshops or occasional advice. You pay only for time used, but costs can be hard to predict.
• Fixed project fee. Good for defined jobs such as a strategy plan, a campaign launch or a website. Scope must be clearly written.
• Monthly retainer. Good for ongoing management of ads, content or CRM. Check exactly what’s included each month.
• Percentage of ad spend. Common for paid ads management. It scales with your budget, but make sure incentives stay aligned with results, not just spend.

Whatever the model, these three rules will protect you:

1. Separate management fees from ad spend. Your ad budget should be paid to Google or Meta from your account.
2. Know what “done” looks like. Agree deliverables and KPIs (for example, cost per lead) up front.
3. Avoid long lock-ins until results are proven. Good consultants are confident enough to earn your business month to month.

Some Irish small businesses can also offset part of the cost of getting online through the Trading Online Voucher (up to €2,500, 50% co-funded) from their Local Enterprise Office. Check eligibility and get approval before committing spend. We cover this in our small business marketing guide.

10 questions to ask before hiring a marketing consultant

1. “Can you show me results for businesses like mine?” Look for specific numbers (spend, leads, revenue) rather than vague praise.
2. “How will you measure success?” The answer should be leads, sales, cost per lead or return on ad spend, not impressions.
3. “Who will actually do the work?” And who is your day-to-day contact?
4. “Will I own my ad accounts, website and data?” The answer must be yes.
5. “What happens in the first 30, 60 and 90 days?” A good consultant has a clear onboarding plan.
6. “How often will we talk, and what will reports include?”
7. “What do you need from me?” Fast approvals and lead feedback are often the difference between average and great results.
8. *“What would you not recommend for my business?”* A good consultant will happily tell you which channels to skip.
9. “How do you cut wasted ad spend?” Listen for negative keywords, exclusion audiences, location targeting and landing-page testing.
10. “What are the contract terms and notice period?”

Red flags to watch for

• Guaranteed results or “#1 on Google”. Nobody controls Google’s rankings or ad auctions. Nobody.
• No access to your own accounts. If they leave, you shouldn’t lose your campaign history.
• Vanity-metric reports. Pages of reach and followers with no mention of enquiries or sales.
• One-size-fits-all packages that ignore your area, margins and capacity.
• Long contracts before any proof of performance.
• Jargon instead of answers. If they can’t explain it simply, they may not understand it, or they don’t want you to.

What a strong first 90 days looks like

Month 1: Audit and foundations. Review accounts, competitors and tracking; fix conversion leaks on the website; agree the offer, target areas and KPIs; set up a CRM pipeline so every lead is captured.

Month 2: Launch and test. Launch focused campaigns (usually Google Search and/or Facebook and Instagram lead ads), test two or three ad angles, add instant SMS/email follow-up, and review search terms and audiences weekly.

Month 3: Optimise and scale. Shift budget to the best-performing ads and audiences, add retargeting and email to past customers, and report clearly on cost per lead and revenue.

What good consulting looks like in practice

The best proof is what clients say. A few examples from businesses we work with:

• A recruitment agency running LinkedIn and Google Ads with us generated 1,000+ potential leads in just over two months.
• A Dublin wine events company saw a 16.4x return on ad spend within the first two weeks of a Facebook campaign. The event sold out.
• A feature walls business reported being fully booked until the new year after one month of leads from paid ads.

One client put it like this: Anthony “explained everything in plain English, kept me updated throughout, and was great to bounce ideas off.” That’s the standard to look for in any consultant, us or anyone else. Read more on our testimonials page.

Is a marketing consultant worth it for small businesses?

For small businesses, a marketing consultant is worth it when the value of the extra customers they help you win is higher than their fee, and when they free up your time to run the business. It’s usually worth it if:

• You’re spending money on ads but can’t tell what’s working
• Enquiries are inconsistent month to month
• You’ve tried DIY marketing and hit a ceiling
• You’re planning to grow, launch a new service or expand to new areas

And honestly, it’s probably not the right time if you have no capacity to take on more work, or no budget to act on the advice.

FAQ about marketing consultants for small businesses

What does a small business marketing consultant do?

They assess how your business currently wins customers, identify the biggest bottleneck, and build a plan to fix it. Depending on the engagement, they may also set up and manage ads, landing pages, tracking, email and CRM, and report on leads and sales.

Is it better to hire a marketing consultant or an agency?

Hire a marketing consultant for strategy and expert direction, an agency for done-for-you execution across several channels. Many small businesses do best with a consultant-led agency: one senior contact plus specialists who carry out the work.

How much does a marketing consultant charge in Ireland?

It depends on experience and scope. Consultants usually charge an hourly or day rate, a fixed project fee, a monthly retainer, or a percentage of ad spend. Always ask for management fees and advertising spend to be quoted separately.

How do I know if a marketing consultant is good?

Ask for specific results from similar businesses, check reviews, and listen to how they define success. Good consultants talk about leads, sales and cost per customer, give you full ownership of your accounts, and explain things clearly.

How long before I see results from a marketing consultant?

Paid advertising can produce enquiries within days, but most campaigns need four to twelve weeks of testing and optimisation to become consistently profitable. SEO and content strategies usually take several months.

Can a marketing consultant work with my business remotely?

Yes. Most marketing work is managed by phone, email and online meetings. We’re based in Kilkenny and work with businesses across Ireland this way.

What does a small business digital marketing consultant do?

A small business digital marketing consultant focuses on online channels: Google Ads, Facebook and Instagram ads, your website, tracking, email and CRM. They find where online enquiries are being lost and fix the biggest gap first.

Is there a small business marketing consultant near me in Kilkenny?

Yes. Simple Marketing Business Development is a marketing consultancy based in Kilkenny, and we work with businesses across Ireland by phone, email and online meetings. You can book a free strategy session to talk through your goals.

What is the difference between a marketing consultant and a business development consultant?

A marketing consultant focuses on attracting and converting customers through channels like ads, websites and social media. A business development consultant looks wider, at sales processes, partnerships and growth opportunities. Many small businesses benefit from a partner who covers both, from first click to closed sale.
