How to Know If Your Marketing Agency Is Any Good — The Commercial Test Most Businesses Skip

I am going to give you a test that will tell you more about a marketing agency in thirty seconds than a two hour pitch ever will. Ready? Ask them this: how does what you do make me money or save me money?

That is it. That is the entire test. If they cannot answer that clearly, immediately and specifically, you have learned everything you need to know. Because every business decision ultimately comes down to one of those two outcomes. You either increase revenue or you reduce cost. Everything else is decoration.

And yet somehow the marketing industry has built an entire ecosystem around avoiding that question. Brand awareness. Engagement rates. Impressions. Share of voice. All perfectly valid metrics in the right context but absolutely useless as primary measures of whether your agency is actually any good.

Think about how you evaluate every other supplier your business uses. Your accountant saves you money on tax or they do not. Your solicitor protects you from liability or they do not. Your logistics provider delivers on time and on budget or they do not. Nobody sits in a meeting with their freight company saying "well the brand awareness of our deliveries has really improved this quarter." You would be sectioned.

But we accept exactly that from marketing agencies. We accept beautifully presented reports full of graphs going up and to the right that somehow never connect to the number that actually matters, which is what went into the bank account and what came out.

So here is how to actually apply the money test. When an agency pitches you, strip away everything they show you and ask three questions. What will this cost me per month? What measurable outcome will it produce? How long before I see it? If they cannot give you straight answers to all three, they are not a commercial partner. They are a cost centre pretending to be an investment.

This is going to sound like an odd tangent but stay with me because it is genuinely one of the most useful things I have learned in thirty years of doing business internationally.

When Chinese businesses evaluate a potential partner or supplier, they do not care about your website. They do not care about your case studies. They do not care about your logo or your office or your team photos. What they want to know is very simple. Are you known in the industry? Do people vouch for you? What is your credit rating? Can you actually deliver?

That is it. Reputation, solvency and capability. The fundamentals.

Compare that to how most British businesses choose a marketing agency. They look at the website. They check the portfolio. They read some case studies that the agency obviously curated to look impressive. They might check a few Google reviews. They sit through a pitch where everything is polished and professional and designed to impress. And then they sign a twelve month contract based largely on vibes.

Nobody checks Companies House. Nobody looks at the agency's actual financial health. Nobody asks around the industry to find out what the agency is genuinely like to work with when the cameras are off. Nobody asks the hard question of whether this agency has ever been taken to court by a client or whether their staff turnover is through the roof, which tells you more about an agency's internal culture than any About page ever will.

The Chinese approach is not more sophisticated. It is more practical. It strips away the performance and looks at the fundamentals that actually predict whether a business relationship will work. And Western businesses would do well to steal that approach wholesale.

Here is a question that will make agency owners uncomfortable. If your marketing agency went bust next month, what would happen to your campaigns, your data and your website?

It is not a hypothetical. Agencies go under all the time. The marketing industry has a failure rate that would make restaurant owners wince. And when an agency folds, clients often discover that their Google Ads account was managed under the agency's master account, that their social media was posted from the agency's tools, that their website is hosted on the agency's infrastructure and that their content was created by freelancers who were never paid and now own the intellectual property.

Checking an agency's financial health is not paranoia. It is basic due diligence. Companies House is free. A credit check costs a few quid. If an agency has been trading for less than two years, has minimal assets and is running on retained earnings from a handful of clients, you need to understand that risk before you hand them your marketing budget.

This is not about only working with big agencies. Some of the best agencies in the UK are small. But financially stable small is very different from one bad month away from insolvency small.

Google reviews tell you what clients think. Industry standing tells you what peers think. Both matter but they measure different things.

A marketing agency can have fifty five star Google reviews and still be regarded within the industry as average. Reviews are retrospective and they are biased toward clients who had a good experience or a terrible one. They do not tell you whether the agency is keeping up with changes in the industry, whether their team has genuine expertise or whether they are just recycling the same playbook from 2019.

Industry standing means something different. It means are they contributing to the conversation? Are they publishing original thinking or just repackaging what everyone else says? Do other agencies respect them or dismiss them? Are they invited to speak at events because they have something to say or because they sponsored a table?

When you are evaluating an agency, look beyond the reviews. Look at what they publish. Look at whether their content demonstrates actual expertise or just repeats conventional wisdom in a slightly different font. Look at whether their leadership is visible in the industry or hiding behind a brand name.

If your agency is reporting monthly, their report should answer five questions clearly. If it does not, ask them why.

First, how much did we spend? Not the agency fee. The total cost including ad spend, tools, production and any additional costs. The real number.

Second, what did we get for it? Not impressions or reach. Leads, enquiries, sales, bookings. The actions that connect to revenue.

Third, what did each of those outcomes cost? Cost per lead, cost per acquisition, cost per sale. The efficiency metric.

Fourth, how does that compare to last month and last quarter? The trend matters more than any single month's number.

Fifth, what are we doing next month to improve those numbers? If the answer is "more of the same" every month, your agency has stopped thinking.

If your current agency cannot or will not report in these terms, that tells you everything about where their priorities lie. An agency focused on making you money will naturally measure the things that connect to money. An agency focused on looking busy will measure the things that make them look busy.

If you are currently working with an agency, apply the money test to your next monthly report. Can you draw a clear line from what you are paying to what you are getting? If not, that is a conversation you need to have.

If you are looking for an agency, do the due diligence that Chinese businesses would do. Check their financials. Ask around the industry. Talk to former clients, not just the ones the agency hand picks for references. Look at their body of work over time, not just the highlight reel.

And if you are not sure where to start, book a call with us. Not because we are the right agency for everyone. We are not. But because we will give you an honest assessment of what you actually need, even if the answer is "not us." That is what commercially focused agencies do. They solve problems rather than sell services.
