Most business owners figure out that an agency was the wrong choice around month three.
By that point, the contract is active, the budget is gone, and the results are either missing or don’t relate to what matters for the business. The relationship ends, sometimes on good terms and sometimes not, and the search begins again.
The frustrating part is that most of the signs were there before the contract was signed. They just weren't easy to recognize at the time.
I run a marketing agency, so I’ve seen this from the inside. I know what works and what doesn’t.
Here’s an honest look at what to watch for before you sign, and what it should feel like to work with a good agency.
When you meet with a potential agency for the first time, it should feel like a focused conversation, not a formal presentation.
If an agency starts by showing off their awards, team size, and client list before asking anything about your business, that’s a red flag. It means they already have a solution in mind without first understanding your needs.
Effective marketing is tailored to each business. For example, a strategy that works for a SPA in Limassol won’t work for an immigration consultancy in London. Before an agency can recommend channels, budgets, or expected results, they need to learn about your product, your clients, your sales process, your past efforts, and where things have gone wrong before.
If these topics don’t come up in your first meeting, the agency’s strategy will likely be generic. And generic strategies usually only deliver average results.
A good first call is filled with questions from the agency. You should leave feeling truly understood, not just pitched to.
Red flag 2: There are no KPIs in the contract
This is the clearest early sign that an agency is not ready to take responsibility for their work.
A contract that lists services like "we will manage your Meta ads, post three times per week on Instagram, produce a monthly report" only describes what the agency will do. It does not explain what results those actions should achieve.
Before you sign, ask the agency what specific metrics they will commit to in the contract. Also, find out what success should look like at 30, 60, and 90 days.
If an agency cannot or will not answer this question clearly, they do not plan to be measured by results. They are offering you their time and effort, not their outcomes.
This is important for both accountability and clarity. Agreeing on KPIs before work starts gives everyone a clear idea of what is working and what is not. Without these measures, disagreements about performance are bound to happen, and there is no clear way to settle them.
A good contract includes a separate list of specific, measurable KPIs that both sides agree on before the first campaign starts. Instead of vague goals like "increase awareness," it should have clear numbers such as cost per lead, ROAS, or the number of qualified enquiries per month.
Red flag 3: They guarantee results without conditions
At first, this might seem surprising. Aren't guarantees supposed to be a good thing?
It really depends on what the guarantee actually covers and what conditions come with it.
If a guarantee says "we guarantee you'll see results" but doesn't explain what results, under which conditions, or in what timeframe, it's not really a guarantee. It's just a sales tactic. When agencies don't clearly define success, they can always point to some metric that improved.
On the other hand, a guarantee that doesn't include any conditions about client behavior is financially risky. Agencies that offer these guarantees either aren't serious or haven't considered what happens if several clients delay sending materials and miss campaign deadlines at the same time.
A real guarantee clearly states what is being promised, how it will be measured, what the client needs to do for it to count, and what happens if the promise isn't met.
A good guarantee includes a specific KPI, a clear way to activate it, clear client responsibilities, and a stated consequence if targets are missed, like offering one month of free service, limited to one time.
Red flag 4: Their reports focus on reach, impressions, and engagement
Before you sign with any agency, ask them for a sample report. How they organize that report will show you a lot about how they approach their work.
If a report starts with reach, impressions, follower growth, and engagement rate, it is measuring activity and visibility, not business results. These numbers have some value, but they are not what business owners need to make decisions. Impressions do not pay the bills.
The most important metrics are the ones that link marketing to revenue. These include cost per lead, cost per acquisition, return on ad spend, revenue from specific campaigns, and how these numbers change each month.
If an agency has never had a client request these metrics, they probably will not include them by default. Agencies that are confident in their results will highlight these numbers up front.
Recently, we've seen the report from the social media agency which was working on a flower shop. They only showed how they changed the Instagram profile visuals. No CPL, no budget, no numbers related to business.
A good report starts with three to five key business metrics. Reach and engagement can be found in an appendix if you want to see them, but they should not be the main proof that things are working.
Red flag 5: The person selling the work is not the person doing it
This is more common in larger agencies than in smaller ones, so it’s something you should be aware of before you sign.
In many agencies, senior strategists or founders handle new business, give the pitch, and present the plan. After you sign the contract, your account might be passed to a junior team. Sometimes, this could be someone with only eighteen months of experience who is also managing eight other clients.
This is not a problem if the agency is upfront about it. The real issue is when you are convinced to sign by someone whose expertise and strategic thinking you will rarely, if ever, interact with again.
Before you sign, ask clearly: Who will manage my account day to day? Who will I talk to each week? Who is in charge of strategy? If these are not the people you’ve already met, ask to meet them before you commit.
What good looks like: the person. Ideally, the person leading the strategy should be easy to reach, join regular check-ins, and take responsibility for the results.
Red flag 6: They cannot show you a case study with real numbers
It’s easy to gather awards, testimonials, and client logos. Getting real, verified results is much harder.
If an agency has truly delivered measurable results, they can show you exactly what happened in a real project, using specific numbers. For example, instead of saying "we increased traffic significantly," they might say "we reduced cost per lead from €85 to €34 over 90 days for a wellness studio in London."
Being specific is important because it shows three things: the agency tracks results carefully, the client trusted them enough to share the numbers publicly, and the results are real, not just general trends.
If a case study does not include clear metrics, or if the agency cannot provide them when asked, it probably means the results were not tracked or were not worth sharing.
A strong agency will have at least two or three published case studies with clear before-and-after numbers.
Red flag 7: There is a long lock-in with no performance exit clause
A 12-month contract that does not allow for early exit based on performance mainly protects the agency, not the client.
Minimum terms exist for good reasons. Meaningful marketing results take time, and a 30-day relationship does not give any agency enough time to build and optimise a campaign properly. For most channels, three months is a reasonable minimum.
However, a contract that makes you keep paying for 12 months even if results are not showing, and gives you no way to exit if agreed KPIs are missed, puts all the risk on the client. This is not a partnership; it is simply a purchase order.
A fair contract has a minimum term of 90 days, a clear review point, agreed KPIs, and an exit option if those KPIs are not met within the set period and it is not the client's fault.
The question to ask before every agency conversation
One question stands out above the rest:
What exact metric will you commit to, and what will you do if you don’t meet it?
If an agency gives a clear and confident answer, naming a metric, a timeframe, and a consequence, they show a level of accountability that most others lack. If they dodge the question, add too many conditions, or focus only on activity metrics, that tells you something important too.
The goal isn’t just to find an agency that makes promises. You want one whose promises are clear and specific enough to matter.
A note on price
Choosing the cheapest agency usually isn’t your biggest risk. More often, the real problem comes from hiring a mid-range agency that charges professional fees but delivers poor results for several months before things fall apart.
Price shouldn’t be your main concern. What matters most is how specific an agency can be. If an agency can clearly explain what they will deliver, under what conditions, how they will measure success, and what happens if they fall short, they are worth more than a cheaper agency that can’t answer these questions.

What should I look for when hiring a marketing agency? Focus on three main things: KPIs that are written into the contract before any work starts, reports based on business results instead of just activities, and case studies with real numbers you can check. These signs reveal more about an agency than any presentation or list of clients.
What are the biggest red flags when evaluating a marketing agency? Watch out for these: no clear KPIs in the contract, reports that focus on impressions and reach instead of cost per lead or revenue, no case studies with real numbers, and contracts that lock you in for a year without a way out if results aren’t delivered.
Is a marketing agency guarantee worth anything? Only if it’s specific. A real guarantee spells out exactly which metric is promised, how it’s measured, what you need to do as the client, and what happens if the goal isn’t met. A vague promise of results is just a sales pitch, not a real commitment.
How long should a marketing agency contract be? Three months is usually a good minimum for most marketing channels. This gives enough time to set up, launch, and start improving results. Longer contracts can make sense if the work is bigger, but they should include a review and a way to leave if performance isn’t there. A year-long contract with no performance terms puts all the risk on you.
Should I ask to see case studies before hiring a marketing agency? Yes, and don’t just look at the logos. Ask for case studies with clear before-and-after numbers, the client’s name, and details about what was done and why. If a case study only says things like "significantly improved results" without numbers, it doesn’t tell you much. Agencies that are proud of their work will share real details.
What questions should I ask a marketing agency before signing? Ask these key questions: What KPIs will you put in the contract? Who will manage my account every day? Can I see a case study with real numbers from a business like mine? What happens if targets aren’t met? How and how often will you report on performance?
How do I know if a marketing agency’s pricing is fair? Don’t judge by price alone. Instead, look at what’s included, what the agency promises, and what happens if they don’t deliver. An agency that charges more but commits to clear KPIs and performance terms can end up costing less than a cheaper agency that gets no results after several months.
