Marketing Audit Checklist: Everything UK SMBs Need to Review Their Agency
Marketing Agency Accountability Checklist
Most business owners never evaluate their agency relationship systematically. They react to problems as they emerge, address individual concerns in isolation, and never step back to assess whether the relationship as a whole is delivering value.
This checklist changes that.
What follows is quite complex framework for evaluating your marketing agency at every stage of the relationship: before you sign, during the engagement, at quarterly intervals, and when preparing to transition. Each section provides specific items to verify, questions to ask, and red flags to watch for.
Use this checklist to conduct your own accountability audit. Work through each section methodically. Document your findings. Where you identify gaps, address them directly with your agency.
The best time to use this checklist is before you notice problems. The second-best time is now.
Pre-Engagement Checklist
Before you sign any agency contract, complete this evaluation. Every item you skip becomes a potential problem later.
Proposal Evaluation
Before committing, ensure you understand exactly what you’re buying:
- [ ] Specific deliverables defined – The proposal lists concrete outputs, not just activities. “12 blog posts per month” not “content marketing.”
- [ ] Measurable goals stated – Success criteria are defined in terms you can verify. Specific lead targets, conversion rates, or revenue outcomes.
- [ ] Timeline provided – Clear milestones for when you should expect to see results, with realistic timeframes.
- [ ] Team identified – The proposal names the specific people who will work on your account, with their qualifications.
- [ ] Pricing breakdown clear – You understand exactly what each pound pays for: management fees, media spend, production costs, technology fees.
Contract Review Items
Demand a sample contract early in discussions, before you’re emotionally invested. Have your agreement reviewed by a solicitor familiar with marketing services. Pay particular attention to:
- [ ] Termination clauses and notice periods – How much notice is required? Is 30 days acceptable, or are you locked into 90+ days?
- [ ] Intellectual property ownership – Insist on full ownership of deliverables upon payment. You should own the work you’ve paid for.
- [ ] Data ownership and access rights – The contract should explicitly state that all data belongs to you.
- [ ] Auto-renewal provisions – Is there any auto-renewal in this contract, and if so, how and when must you notify them to prevent it?
- [ ] Scope definitions – Demand specificity in quantities and deliverables. Vague terms like “SEO optimisation” create disputes later.
- [ ] Limitation of liability – Negotiate for higher caps tied to insurance limits, not minimal fee-based caps.
Learn more about contract red flags to watch for.
Direct Questions to Ask
Before signing, ask these direct questions and get answers in writing:
- [ ] “If we’re dissatisfied, exactly how much notice must we give to terminate?”
- [ ] “Will we maintain administrative access to all platforms and data?”
- [ ] “Is there any auto-renewal in this contract, and if so, how and when must we notify you to prevent it?”
- [ ] “Who specifically will be working on our account day-to-day?”
- [ ] “Can you provide references from clients in similar industries?”
- [ ] “What happens to our data and accounts if we end the relationship?”
Red Flag Indicators
Walk away if you encounter any of these (and check the full list of marketing agency warning signs for a deeper breakdown):
- [ ] Agency won’t provide sample contract before detailed discussions
- [ ] Vague answers to direct questions about deliverables or costs
- [ ] Pressure to sign quickly (“This rate is only available this week”)
- [ ] Unwillingness to name specific team members
- [ ] Refusal to discuss termination terms
- [ ] No clear explanation of how success will be measured
Monthly Accountability Checklist
Use this checklist every month to verify your agency is delivering value. Don’t wait for quarterly reviews to identify problems.
Performance Review
Every monthly report should answer these questions:
- [ ] Revenue metrics reported? – Can you trace marketing activity to actual business outcomes: leads, sales, revenue?
- [ ] Cost metrics clear? – Do you know your true cost per lead, cost per acquisition, and return on ad spend?
- [ ] Conversion data provided? – Are you seeing the full funnel: impressions to clicks to enquiries to customers?
- [ ] Comparison to goals? – Is performance measured against the targets agreed at the start of the engagement?
- [ ] Trend direction clear? – Is performance improving, declining, or flat? Over what timeframe?
If your reports focus heavily on impressions, reach, and engagement without connecting to business outcomes, that’s a problem. Learn more about vanity metrics vs business metrics.
Activity Verification
Verify that your agency is actually doing the work:
- [ ] Optimisations documented? – Can they show you specific changes made to campaigns this month?
- [ ] Tests running? – Are they actively testing ad variations, audiences, or landing pages?
- [ ] Strategy updates explained? – Have they adapted strategy based on performance data?
- [ ] Change history available? – Can you see actual platform change logs, not just summaries?
If campaigns haven’t changed substantially in months, you may be paying for management that isn’t happening. Learn more about autopilot campaigns.
Communication Quality
Evaluate how well your agency communicates:
- [ ] Regular updates received? – Are you hearing from them proactively, not just when you chase?
- [ ] Questions answered promptly? – When you ask questions, do you get clear, specific responses?
- [ ] Proactive recommendations? – Are they suggesting improvements, or just executing existing plans?
- [ ] Accessible contacts? – Can you reach the people actually working on your account?
Access and Transparency
Verify you have the access you’re entitled to:
- [ ] Platform access available? – Do you have admin access to all advertising and analytics platforms?
- [ ] Reporting accuracy verifiable? – Can you check the numbers they report against platform data?
- [ ] Costs transparent? – Do you know exactly where every pound of your budget goes?
- [ ] Data exportable? – Can you download your data in standard formats whenever you want?
If your agency restricts access to your own accounts, that’s a serious red flag. Learn more about why agencies restrict admin access.

Quarterly Deep Dive Checklist
Every quarter, step back from monthly details and evaluate the relationship as a whole.
ROI Assessment
- [ ] Total investment calculated – Add up all agency fees, media spend, and related costs for the quarter.
- [ ] Revenue attributed – What revenue can you reasonably attribute to marketing activities?
- [ ] ROI calculated – Is the return on your marketing investment positive? By how much?
- [ ] Trend analysis – Is ROI improving quarter over quarter, or declining?
- [ ] Benchmark comparison – How does your ROI compare to industry benchmarks or your own historical performance?
If you can’t calculate ROI because you don’t have the data, that’s itself a significant problem.
Strategy Alignment Review
- [ ] Goals still relevant? – Have your business objectives changed? Does the marketing strategy still align?
- [ ] Market conditions considered? – Has the competitive landscape shifted? Is the strategy adapting?
- [ ] Opportunities identified? – Is the agency proactively identifying new opportunities, or just maintaining the status quo?
- [ ] Lessons applied? – Are insights from the past quarter being applied to improve future performance?
Fee and Value Assessment
Request a complete breakdown of where every pound of your budget goes:
- [ ] Actual media spend (with platform verification)
- [ ] Agency management fees
- [ ] Production costs
- [ ] Technology/software fees
- [ ] Any other charges
Compare the value received against the fees paid. Is the relationship delivering fair value?
Team Assessment
Confirm who is actually working on your account and their qualifications:
- [ ] Request CVs/LinkedIn profiles of all team members (LinkedIn is a safer option)
- [ ] Ask for time allocation (how many hours each person dedicates to your account)
- [ ] Verify if work is being outsourced/white-labeled
- [ ] Confirm continuity – Are the same people working on your account, or has there been turnover?
Learn more about the bait-and-switch problem.
Contract Status Review
- [ ] Contract end date identified – When does your current agreement expire?
- [ ] Notice period calculated – When must you give notice if you want to leave?
- [ ] Auto-renewal date marked – If applicable, when is the window for preventing auto-renewal?
- [ ] Exit costs understood – What would it cost to leave the relationship today?
Calendar the critical dates for cancellation windows. Scheduling an email to yourself works like a charm. Do it immediately, otherwise you’ll forget.
Relationship Health Check
- [ ] Trust level – Do you trust what your agency tells you?
- [ ] Responsiveness – Do they respond promptly and thoroughly to your questions?
- [ ] Proactivity – Do they bring you ideas and opportunities, or wait for instructions?
- [ ] Alignment – Do you feel they’re working for your success, or just collecting fees?
Be honest with yourself. If the relationship doesn’t feel right, investigate why.

Transition Checklist
If you’ve decided to change agencies or bring marketing in-house, use this checklist to ensure a clean transition.
Data Export
Before giving notice, secure your data:
- [ ] Export Google Analytics data – Download all historical data in standard formats.
- [ ] Export advertising account data – You can export the whole Google Ads account and re-import it on your own with Google Ads Power Editor.
- [ ] Download audience data – Custom audiences, remarketing lists, lookalike audiences.
- [ ] Save conversion tracking setup – Document all pixel configurations and tracking code.
- [ ] Export CRM data – All lead and customer data generated through marketing activities.
Don’t wait until after you’ve given notice. Export data now while you still have full access.
Asset Transfer
Ensure you retain ownership of all assets:
- [ ] Creative files – All design files, ad creative, video assets in editable formats.
- [ ] Website access – Admin credentials for any websites or landing pages.
- [ ] Email templates – All email marketing templates and automation workflows.
- [ ] Content library – All blog posts, guides, and content assets.
- [ ] Brand assets – Any logos, brand guidelines, or visual assets created.
Account Access
Verify you control all relevant accounts:
- [ ] Google Analytics – You should be the account owner, not a user on agency’s account.
- [ ] Google Ads – Account should be in your name with you as admin. Use Google’s manage access settings to verify your access level.
- [ ] Meta Business Manager – You should own the Business Manager, not the agency.
- [ ] All social media accounts – Verify you have admin access to all profiles.
- [ ] Any other advertising platforms – LinkedIn, Twitter, programmatic platforms, etc.
If accounts are in the agency’s name, negotiate transfer before giving notice. This is much harder after the relationship ends.
Documentation
Request complete documentation for handover:
- [ ] Strategy documents – Current strategy, rationale, and planned activities.
- [ ] Campaign structure – How campaigns are organised and why.
- [ ] Test history – What’s been tested, what worked, what didn’t.
- [ ] Audience insights – What they’ve learned about your target audience.
- [ ] Vendor relationships – Any third-party relationships they manage on your behalf.
Transition Timeline
- [ ] Notice period confirmed – Verify exact requirements per your contract.
- [ ] Handover period negotiated – Request reasonable transition support.
- [ ] New provider identified – Have your next solution ready before giving notice.
- [ ] Parallel running period planned – If possible, overlap old and new providers briefly.
Consider negotiating an early exit if performance is poor. Sometimes agencies will release you rather than risk reputational damage.
Put This Checklist to Work
A checklist only creates value when you use it. Here’s how to start:
This week: Complete the Monthly Accountability section for your current agency. Note any items you can’t verify or questions you can’t answer.
This month: Schedule a quarterly deep dive, even if it’s not technically the quarter end. Complete the full quarterly assessment.
Before any new engagement: Work through the Pre-Engagement checklist completely before signing anything.
If you complete this checklist and find significant gaps, that’s not failure. That’s awareness. Now you can address those gaps systematically rather than discovering them during a crisis.
The agencies that deliver value welcome accountability. They’re confident in their work and happy to demonstrate results. If your agency resists the transparency this checklist requires, that resistance itself is an answer.
