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.

Quick Start (15 Minutes)
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.
Your 5-Step Evaluation Process
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:
- •"10 more qualified discovery calls per month"
- •"Reduce cost per lead from £45 to £30"
- •"Increase email conversion rate from 2% to 4%"
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:
- Guaranteed rankings or results – No one can guarantee Google rankings or viral content
- Vague reporting – "We'll send monthly updates" without specifying which metrics
- No contract or unclear terms – Professional services always have clear agreements
- Proprietary tools you can't access – You should own your data and be able to export it
- Pressure to sign immediately – Good providers are busy; they don't need to pressure you
Top 5 Red Flags When Interviewing Marketing Providers
Step 4: Demand Specific Proof
Ask: "Show me three projects similar to mine where you achieved measurable results."
Look for:
- •Businesses of similar size (not just big brand logos)
- •Similar industries or challenges
- •Specific numbers (not "increased traffic significantly")
- •Timeframes (results in 3 months vs 18 months matters)
Step 5: Complete Your Evaluation Matrix
Use this template to score each potential provider:
Your Marketing Help Evaluation Matrix
Rate each criterion 1-5:
- •Relevant proof of results (case studies)
- •Clear process documentation
- •Transparent pricing structure
- •Communication style and responsiveness
- •Contract terms and exit clauses
Anyone scoring below 3 on any criterion needs to address it before you proceed.

Complete Step-by-Step Guide: The 5-Point Evaluation Framework
This section walks you through building a comprehensive evaluation system that protects you from the most common hiring mistakes.
Step 1: Define the Specific Mandate (Goal vs. Channel)
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:
- •Wrong: "I need blog content"
- •Right: "I need to rank for 5 specific search terms that my ideal customers use, to generate 15 organic leads per month"
- •Wrong: "I need email marketing"
- •Right: "I need to convert 25% of my trial users into paying customers through automated email sequences"
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?
Step 2: The "Three P's" Test: Proof, Process, Price Structure
Every provider you interview must pass all three tests. Miss one, and you're taking unnecessary risk.
Proof: Demand Quantifiable Case Studies
"We've worked with hundreds of businesses" means nothing. You need specific, relevant proof.
What to ask:
- •"Show me three projects where you achieved results for businesses similar to mine."
- •"What were the specific metrics before and after?"
- •"How long did it take to achieve those results?"
- •"What didn't work, and how did you adapt?"
What good proof looks like:
Example of Required Performance Report Snapshot
Look for:
- •Specific numbers (not percentages without context)
- •Timeframes clearly stated
- •Honest discussion of challenges
- •Businesses of similar size and industry
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.
Process: Ask How They Achieve Results
This is where you separate professionals from chancers. A real expert can explain their system.
What to ask:
- •"Walk me through your process from day 1 to day 90."
- •"What do you need from me, and when?"
- •"How do you report progress, and how often?"
- •"What happens if results aren't meeting expectations at 30 days?"
What good process looks like:
- •Clear phases with specific deliverables
- •Defined decision points and approval stages
- •Regular reporting schedule (weekly or fortnightly for most projects)
- •Documented workflows they can share
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.
Price: Ensure Structure Reflects Milestones
How they price tells you how they think about value.
Three pricing models:
- Hourly: Risky for you—no incentive for efficiency
- Monthly retainer: Common, but must be tied to deliverables
- Project-based: Best for defined scope, but needs clear milestones
What to insist on:
- •Payment tied to completed milestones, not just time passed
- •Clear deliverables for each payment point
- •Performance review gates (especially at 30 days)
Example structure:
- •30% upfront for discovery and setup
- •40% at 30-day checkpoint (if minimum viable results achieved)
- •30% at project completion
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.
Step 3: Red Flags and Trust Signals
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.
Automatic Disqualifiers
These should end the conversation immediately:
1. Guaranteed rankings or specific results
- •No one can guarantee Google rankings
- •No one can guarantee content will go viral
- •Results depend partly on factors outside their control
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
- •You should own all your data
- •You should be able to export everything
- •You should be able to continue the work if you part ways
Red flag phrases:
- •"We use our proprietary system"
- •"The data lives in our platform"
- •"You'll need to stay with us to maintain access"
3. Vague reporting or "trust the process" language
Specific reporting looks like:
- •"Weekly dashboard showing leads generated, cost per lead, and conversion rate"
- •"Fortnightly calls to review performance against the 3 KPIs we agreed"
- •"Monthly written report with recommendations for next phase"
Vague reporting sounds like:
- •"We'll send updates"
- •"You'll see the results"
- •"Monthly check-ins to discuss progress"
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:
- •Defined scope of work
- •Payment terms and schedule
- •Ownership of deliverables
- •Notice period and exit process
- •What happens if results aren't achieved
Trust Signals to Look For
Positive indicators:
- •They ask detailed questions about your business before proposing solutions
- •They're honest about what they can't do or don't specialise in
- •They provide references you can actually contact
- •They explain risks and challenges, not just opportunities
- •They propose a small test project before a large commitment
Step 4: Setting the Contract and Accountability
The contract protects both parties, but it especially protects you from scope creep and underperformance.
What Must Be in Writing
Scope of work:
- •Specific deliverables (not "SEO services" but "15 optimised blog posts targeting these keywords")
- •Timeline with milestones
- •What's explicitly excluded
Performance expectations:
- •The 1-3 KPIs you're measuring
- •Minimum acceptable results at 30, 60, and 90 days
- •What happens if minimums aren't met
Ownership and access:
- •You own all content, designs, and data created
- •You retain access to all platforms and tools
- •You can export everything if the relationship ends
Exit terms:
- •Notice period (typically 30 days)
- •What you receive if you terminate early
- •No penalty fees for ending based on non-performance

What to Keep In-House vs Outsource
Even with external help, some things should stay under your control:
Keep in-house:
- •Access to core platforms (website, email, social accounts)
- •Final approval on messaging and brand decisions
- •Customer data and CRM access
- •Budget allocation decisions
Can outsource:
- •Execution of approved strategy
- •Content creation and design
- •Technical implementation
- •Reporting and analysis
See our full guide on what to keep in-house vs outsource for detailed decision criteria.
Step 5: The 30-Day Checkpoint
This is your safety net. Most problems reveal themselves within 30 days.
Set Up Your First Review
Before work starts, agree on:
- •Exactly what should be completed by day 30
- •The minimum viable result you expect to see
- •What data you'll review together
- •What happens if expectations aren't met
Example 30-day checkpoints:
For SEO work:
- •Technical audit completed and priority fixes implemented
- •5 pieces of optimised content published
- •Baseline rankings documented for target keywords
- •Clear roadmap for months 2-3
For paid advertising:
- •Account structure set up and approved
- •First £500 spent with full tracking in place
- •Cost per click and cost per lead documented
- •At least 3 ad variations tested
For content/copywriting:
- •4 pieces delivered and published
- •Engagement metrics baseline established
- •Content calendar for next 60 days approved
- •Clear process for revisions and approvals
Structure Payment Around This Milestone
Recommended payment structure:
- •20-30% upfront (covers setup and discovery)
- •30-40% at 30-day checkpoint (only if minimum results achieved)
- •30-40% at completion or monthly thereafter
If the 30-day checkpoint isn't met:
- •Pause further payment until issues are resolved
- •Require a written recovery plan with specific deadlines
- •Consider whether to continue or exit
This structure ensures you're never more than 30 days and one payment into a relationship that isn't working.
