Assess marketing agencies and freelancers properly. Know what to look for and red flags to avoid.
You've decided you need help with your marketing. Smart move—but here's the uncomfortable truth: hiring the wrong person or agency will cost you far more than their fee. You'll lose time, budget, and momentum whilst they experiment with your business. The average micro-business wastes £3,000-£8,000 on marketing help that delivers nothing measurable.
This article gives you the objective framework to shift the burden of proof onto the vendor. You'll learn exactly what to demand, which red flags to spot immediately, and how to structure accountability from day one. No more impressive pitch decks that lead nowhere. No more "trust the process" when there's no process to trust.
What You'll Have When Done:
A completed evaluation checklist focusing on critical red flags and measurable outcomes you can use in your first interview.
Time Needed: 15 minutes
Difficulty: Confident
Prerequisites:
The Win: Walk into any pitch meeting with objective criteria that immediately separate serious professionals from time-wasters.

Before You Start:
Make sure you've completed these steps:
Why This Matters: Without clear evaluation criteria, you'll make emotional decisions based on who you "like" rather than who can actually deliver results.
Ready to vet their claims? Before interviewing anyone, run a NetNav audit. It gives you an independent, objective baseline of your site health, so you know exactly where you stand before any new help starts making claims about 'fixing' things you didn't even know were broken.
Step 1: Define Your Single Non-Negotiable Outcome
Write down one specific, measurable business result. Not "better SEO" or "more social media engagement"—those are activities, not outcomes.
Examples:
This becomes your filter for everything else.
Step 2: Review Proposals Against That Outcome Only
Read their proposal. If it doesn't explicitly explain how their work connects to your specific outcome, discard it.
If they're selling you "TikTok strategy" but your outcome is "more B2B leads from manufacturing directors", there's a disconnect. They should explain the connection, not expect you to trust it exists.
Step 3: Identify Your 5 Critical Red Flags
Mark these as automatic disqualifiers:

Step 4: Demand Specific Proof
Ask: "Show me three projects similar to mine where you achieved measurable results."

Step 5: Complete Your Evaluation Matrix
Use this template to score each potential provider:

This section walks you through building a comprehensive evaluation system that protects you from the most common hiring mistakes.
The first mistake micro-businesses make is hiring for a channel ("we need someone to do Facebook ads") rather than for an outcome ("we need to reduce our cost per customer").
Start with your business goal, not the marketing tactic.
Your mandate should answer: "What business problem am I solving?"
Examples:
The provider should then propose how they'll achieve that outcome. If they immediately jump to tactics without understanding your goal, that's red flag #1.
Connect this to your numbers: Before any conversation, calculate your cost per lead. If you're currently paying £50 per lead and they're proposing work that costs £2,000/month, you need 40 additional leads just to break even. Does their proposal make that realistic?
Every provider you interview must pass all three tests. Miss one, and you're taking unnecessary risk.
"We've worked with hundreds of businesses" means nothing. You need specific, relevant proof.
What to ask:
What good proof looks like:
[MEDIA:SCREENSHOT:proof-of-work-template]
Example of Required Performance Report Snapshot
Look for:
Red flag: They only show you big brand logos or "increased traffic by 300%" without baseline numbers. A 300% increase from 10 visitors to 40 visitors is meaningless.
Portfolio review tip: If they show you landing pages or content, evaluate them using the same principles you'd use for your own work. Are the CTAs clear? Would you click them? See our guide on writing effective CTAs for what to look for.
This is where you separate professionals from chancers. A real expert can explain their system.
What to ask:
What good process looks like:
Demand they document simple processes just like you should for your own business. If they can't explain their process clearly, they don't have one—they're winging it.
Red flag: "We'll figure it out as we go" or "every client is different so we don't have a standard process." Adaptation is fine; having no system is not.
How they price tells you how they think about value.
Three pricing models:
What to insist on:
Example structure:
Connect pricing back to your cost per customer. If they're charging £3,000 and your average customer value is £500, you need at least 6 new customers just to break even. Make sure their proposal makes that realistic.
A good agency will immediately identify foundational issues, but you shouldn't pay them their high hourly rate to find the low-hanging fruit. Use NetNav to quickly identify technical SEO gaps or website speed issues. This ensures your budget goes towards strategic execution and complex problem-solving, not basic cleanup.
These should end the conversation immediately:
1. Guaranteed rankings or specific results
What they should say instead: "Based on similar projects, realistic expectations are X, and we'll know within 30 days if we're on track."
2. Proprietary tools or platforms you can't access
Red flag phrases:
3. Vague reporting or "trust the process" language
Specific reporting looks like:
Vague reporting sounds like:
4. Pressure to sign immediately
Professional providers are usually booked 2-4 weeks out. If they're pushing you to sign today, ask why they're not busy.
5. No clear contract or exit terms
Every engagement needs:
Positive indicators:
The contract protects both parties, but it especially protects you from scope creep and underperformance.
Scope of work:
Performance expectations:
Ownership and access:
Exit terms:

Sample KPIs by Engagement Type (SEO, Ads, Copywriting)
Even with external help, some things should stay under your control:
Keep in-house:
Can outsource:
See our full guide on what to keep in-house vs outsource for detailed decision criteria.
This is your safety net. Most problems reveal themselves within 30 days.
Before work starts, agree on:
Example 30-day checkpoints:
For SEO work:
For paid advertising:
For content/copywriting:
Recommended payment structure:
If the 30-day checkpoint isn't met:
This structure ensures you're never more than 30 days and one payment into a relationship that isn't working.
You've Completed the Full Framework When:
Validation Check: Show your evaluation framework to another business owner. Can they use it to interview their own providers? If yes, it's robust enough.
🎉 Completed? You've defined your hiring criteria and avoided the major pitfalls. You're ready for Outsourcing: How to Write a Brief for a Freelancer.

Common Problems and Fixes
Problem: "They had an impressive pitch deck and great testimonials, but I'm not seeing results."
Why this happens: You focused on presentation rather than proof. Testimonials are curated; anyone can make a nice slide deck.
Fix: Go back to the Three P's. Demand specific, quantifiable proof from similar projects. If they can't provide it, walk away regardless of how polished their pitch is. Insist that 80% of your discussion focuses on their specific process and proof (the "How" and "What happened previously"), not their vision or philosophy.
Problem: "They're selling me on TikTok/Instagram/[channel], but I'm not sure it connects to my actual business goal."
Why this happens: They're selling what they do, not what you need. Many providers specialise in a channel and try to fit every client into it.
Fix: Clearly state your business goal (e.g., "increase qualified leads by 15%") and demand they explain exactly how their proposed channel achieves that specific goal. If they can't draw a direct line from their tactic to your outcome, they're guessing. Being sold a channel instead of a strategy aligned with your business goal is a major red flag.
Problem: "The price seems reasonable, but I don't know if I'm getting value."
Why this happens: You're comparing hourly rates or monthly fees without connecting them to business outcomes.
Fix: Structure payment around clear milestones and defined deliverables, not just hourly rates or time passed. Calculate what result you need to justify the cost (if they charge £2,000/month and your profit per customer is £400, you need 5 new customers per month just to break even). If their proposal doesn't make that realistic, the price isn't reasonable regardless of the hourly rate. Focus on value and accountability, not just cost.
