Is a marketing agency worth it, and when it plainly is not

What a marketing agency actually does all month

The service names hide the work, so it is worth saying plainly what the hours go on. Almost every agency retainer is some combination of five activities, and knowing which ones you are buying is most of the argument about whether the price is fair.

• Buying and managing media. Setting up campaigns, watching what they return, moving budget between the parts that work and the parts that do not.
• Producing creative. Writing the advertisements, making the images and video, and replacing them when they stop working, which they do.
• Making pages and content. Landing pages, articles, product descriptions and whatever else the campaign needs somewhere to send people.
• Measurement. Making the tracking honest, then reporting what happened in a form that survives a hard question from the person paying.
• Deciding what to do next. This is the smallest part by hours and the largest part by consequence, and it is the one most likely to be done by whoever sold you the engagement rather than whoever works on it.

An agency that cannot tell you the split between those five for your account has not planned your account. Ask for it as hours or as a rough percentage of the retainer, and ask again in month three, when the answer often turns out to have changed.

The arithmetic that decides it

Worth it is not a feeling. It is a break-even you can calculate on the back of an envelope, and doing so takes about four minutes.

Add the retainer and the media budget together. That is what leaves your account each month. Now take the gross profit on one new customer, across the whole time they stay with you rather than on their first order. Divide the first number by the second. The result is how many extra customers a month the arrangement has to produce before you have gained nothing and lost nothing.

Compare that number to what you win now. If the agency has to roughly double your monthly new business simply to break even, you are not buying growth, you are buying a bet. That can still be the right decision, but it should be made knowingly rather than discovered in month five.

Three situations where an agency is not worth it

These are the cases where the answer is no regardless of which agency you pick, and an agency willing to say so is telling you something useful about how they work.

The first is an offer that has never sold. Advertising finds out what a market thinks of your proposition, quickly and at full price. If nobody has bought it yet without paid promotion, buying an audience is an expensive way to receive an answer that ten direct conversations would have given you for nothing.

The second is margin that cannot carry the cost of acquisition in your category. This is arithmetic, not execution. If the gross profit on a customer is smaller than what it costs to win one where you compete, no amount of optimisation closes that gap, and the honest move is to change the offer, the price or the category rather than the agency.

The third is a business with nobody free to answer the enquiries. Marketing creates obligations to reply. A business that is already slow to reply will become visibly slow to reply, and will conclude that the leads were poor. The cheapest improvement available to most businesses is not more enquiries. It is answering the ones already arriving faster than the competitor did.

What actually makes it worth it

When an agency does pay for itself, it is rarely because of one clever idea. It is because a working process arrives already built. Somebody has structured an account before, has seen what a fortnight of bad data looks like, and knows which of the twenty possible causes to check first.

The second thing you are buying is range. One competent marketing hire covers perhaps two of the five activities above properly. An agency covers all five at some level of quality, which is why the comparison against a single salary is usually the wrong comparison. We set that out in full in an agency, an in house team, or neither.

The third is consistency, which sounds dull and decides most outcomes. Marketing that happens every week beats better marketing that happens whenever somebody has an afternoon free, and an outside party with an invoice attached is one of the more reliable ways to make a thing happen every week.

How long before you can tell

Long enough for the difference between one version and another to be distinguishable from noise, which is a question of volume rather than of calendar months. An account producing many enquiries a week can be read quickly. An account producing a handful cannot be read at all in the same period, and reading it anyway produces confident conclusions that never repeat.

What you can judge early is process rather than results. In the first month, did they fix the measurement before optimising anything? Did the first report state what is uncertain as well as what improved? Did anybody name a thing that went wrong before you noticed it? Those are readable in weeks and they predict the rest better than an early good month does.

The part that survives the last invoice

Here is the question the worth-it argument usually skips. On the day the arrangement ends, what do you still have?

With hours, the answer is an account, some creative and a gap where a process used to be. That is not a criticism of agencies; it is the nature of buying time. It is also why the same monthly figure can be worth very different amounts depending on what it leaves behind.

The repeatable half of that work does not have to be rented. Reporting, the reconciliation between platform numbers and your own records, the first version of every creative variation, the reply that goes to an enquiry within a minute at any hour: all of it can be built once and left running in your own accounts, with a person keeping the judgement. That is a different purchase from a retainer, it is not automatically the better one, and the honest comparison is in renting the output against owning the system.

What survives the last invoice, in one company's case

The final question above deserves a specific answer rather than a principle, so here is one. Wobble builds inside the client's own accounts, so on the day an arrangement ends the account structure, the creative, the audience definitions and the automations are still there, under logins the client already holds. Published alongside that is the work itself: investor leads at $19.79 for Massive Capital, 89 conversions in ninety days at $1.54 a click for Zavcom, 3.97 million lifetime impressions for Palm Berries at twenty cents average cost per click. Twenty five engagements across six countries, worked from Karachi and billed month to month.

Ali owns marketing and sales at Wobble and Haad owns growth and client solutions. Between the four co-founders the routes into this company run through medicine, chartered accountancy, media, military school and businesses that had to make payroll rather than through an agency graduate scheme. Whether that reads as a recommendation is yours to decide. What it changes in practice is that the break-even arithmetic above tends to be the first conversation rather than a slide near the end of one.

The three activities inside a retainer that carry real risk all stop for a person. Changes to spend, anything published in the client's name and any reply to a public complaint wait for human approval, and where an automation meets a case it was not built for it hands it to a person instead of posting something plausible. An agency that lets a system publish unsupervised is not being efficient. It is moving the consequence onto the client while keeping the fee.

And the honest version of the three conditions. Where the offer does not yet sell to anybody, an agency multiplies a problem that was never marketing. Where the margin does not survive the fee, the arithmetic settles it before any meeting happens. Where somebody inside the business has the hours and the interest, keeping it in-house is usually better, because the person who cares most about the account is the one whose income depends on it. Saying that costs a supplier work, which is precisely why it is worth reading from one.

Common questions

Is a marketing agency worth it?

It is worth it when you already have an offer that sells, margin that survives the fee, and nobody inside the business with the hours to run the channel properly. Take the retainer plus the media budget, divide by the gross profit on one customer across their whole relationship with you, and look at how many extra customers a month that implies. If the number is close to doubling your current new business, you are buying a bet rather than growth.

Is it worth it to hire a marketing agency instead of doing it myself?

Doing it yourself wins when the work is narrow, your market is small and you can genuinely give it the same hours every week for a year. An agency wins on range, because one person covers perhaps two of the five activities in a retainer properly and an agency covers all five at some standard. The usual failure of the do it yourself route is not skill, it is that it stops happening in month three.

What exactly do marketing agencies do?

Five things in some combination: buy and manage media, produce creative, make pages and content, keep the measurement honest, and decide what to do next. Deciding is the smallest part by hours and the largest by consequence. Ask any agency for the split across those five for your specific account, because an agency that cannot give you one has not planned your account.

When is a marketing agency not worth it?

When the offer has never sold without paid promotion, when the gross profit per customer is smaller than what winning one costs in your category, or when nobody in the business is free to answer the enquiries that arrive. The third is the most common and the cheapest to fix, and fixing it improves every channel you already have rather than only the new one.

How long before I can tell whether an agency is working?

Results become readable when enough conversions have accumulated for one version to be distinguishable from another, which depends on volume rather than on the calendar. Process is readable much sooner. In the first month, look at whether they fixed the measurement before optimising anything, and whether the first report named what is uncertain rather than only what improved.

What is the 3-3-3 rule in marketing?

The 3-3-3 rule in marketing has no single agreed version, which is worth knowing before somebody quotes it at you with confidence. The label gets attached to a posting cadence, to a follow-up sequence and to how long a visitor spends deciding whether to stay on a page. Ask whoever used it which one they mean. A phrase that means three different things is a mnemonic rather than a method, and none of its versions tells you whether to hire anyone.
