Picking a digital marketing agency is one of those decisions where the cost of getting it wrong is usually a lot bigger than the monthly fee. Six months of a bad fit can mean burnt ad budget, lost data, a watered-down brand and a sales pipeline that never quite shows up. So it is worth taking the time to look for the right signals before you sign anything.
Here is what we think the green flags and the red flags actually look like, written by someone who has cleaned up after a fair few of the latter.
The green flags
Transparency. A good agency will tell you exactly what they are doing in your account each month, in language you can follow. You should never feel like the work is happening behind frosted glass.
Accounts set up in your name. Your Google Ads account, your Meta Business Manager, your GA4 property, your Google Business Profile. These should all be created under your business, with you as the owner, and the agency given user access. If the agency owns the accounts, you do not own your data, your tracking history or your audience lists. The day the relationship ends, you start from zero.
Reporting that talks about revenue and leads. Not impressions, not reach, not click-through rate in isolation. Those numbers can all go up while your bank account stays flat. A good report tells you how many qualified leads came in, what they cost, and what happened to them.
Explaining the why. When the agency makes a change, they should be able to tell you why in a sentence you understand. "We paused this ad group because cost per lead was running double the others" is a good answer. "We optimised the structure" is not.
No lock-in tricks. A month-to-month arrangement, or at most a short initial term while things ramp up, is reasonable. Multi-year contracts with painful exit clauses usually exist for the agency's benefit, not yours.
Talking about your business, not just their deliverables. Before they pitch a package, the people across the table should have asked about your average sale value, your margin, your sales process, who your best customers are and what you actually want more of. If the conversation jumps straight to a price list, that is a sign.
The red flags
Guaranteed number one rankings or a guaranteed specific return. Nobody can promise either honestly. The Google algorithm changes, the auction shifts, competitors react. An agency that promises a fixed result is either making it up or planning to game it in a way that will eventually hurt you.
Refusing to give you account access. Sometimes dressed up as "we manage everything for you so you do not have to worry about it". You should always have at least read access to every account spending your money. Always.
Vague reporting. PDF reports full of charts and no commentary, screenshots that focus on the metrics that happen to look good this month, a refusal to talk about cost per lead or cost per sale. If you cannot tell from a report whether the work made you money, the report exists to obscure, not to inform.
Long lock-in contracts paired with hard cancellation terms. If the agency is confident in their work, they do not need to trap you in.
A polished salesperson at the pitch, then a junior doing the actual work. Plenty of agencies sell with their best people and deliver with their cheapest. Ask directly who will be in your account day to day, and how much experience they have.
Jargon used to hide a lack of substance. If everything is described in acronyms and you leave the meeting unsure what they will actually do, that is a deliberate choice, not a coincidence.
No proper conversion tracking. If they are happy to start spending your money before tracking is set up correctly, they are happy to optimise toward whatever signal Google happens to find, qualified or not. That gets expensive quickly.
Questions worth asking before you sign
Who will be working on my account day to day, and how much of their time will I get?
Will the ad accounts, analytics and Google Business Profile be set up in my name with me as the owner?
How do you measure whether the work is succeeding, and what does your monthly reporting actually look like?
What is the minimum term, and what happens if I want to leave?
Can you walk me through an account you have worked on and what you actually did?
Founder-led is not automatically better
We should be honest, because we are a founder-led studio and it would be too convenient to argue otherwise. Smaller is not automatically better. There are excellent larger agencies and there are average boutique ones. The real point is direct accountability. You should know who is doing your work, you should be able to talk to that person, and that person should be able to explain in plain language what is happening and why.
Whether that is a founder, a senior strategist inside a bigger team or a specialist freelancer matters less than whether the line of accountability is short and visible.
A no-obligation way to see how someone thinks
The best signal you will get from any agency is not the pitch deck. It is how they talk about your business when there is no contract on the table. That is exactly why our free audit exists. We will look at your accounts, your tracking and your site, tell you what we would change and why, and you keep that whether or not we end up working together. It is a low-stakes way to find out how a potential partner actually thinks.
