Should you hire a marketing agency, build in-house, or do it yourself?

Most expert-led firms eventually face the same fork. Hire an agency, hire a marketer, or do the marketing yourself.

The comparison is usually written up as a balanced table, pros and cons in tidy columns. The table reads balanced because whoever wrote it sells one of the columns. What the tables rarely include is thresholds, meaning the numbers at which the answer changes.

You already hold those numbers. Your budget, your available hours, and the standard your name requires. This post prices each branch against them.

Price the do-it-yourself branch at your own billing rate

Start with doing it yourself, because most owners start there.

The price of this branch is your hours, at your billing rate. Orbit Media surveys well over a thousand bloggers every year. In the 2025 survey, a typical post took just under three and a half hours to produce. The same series finds the longer efforts win more often. The six-hour writers report strong results at a higher rate.

Now run your own rate against that. A consultant who bills $300 an hour is writing $1,000 blog posts, before distribution, before email, before anything social. Marketing at a useful cadence is a weekly commitment. The owner's calendar is the firm's most expensive place to fund it.

Two things about AI belong here, and they point in different directions.

Drafting has collapsed. In Orbit's data, the share of bloggers using no AI fell from 65% to 5% inside two years. A capable owner with a chatbot can now produce in an evening what once took a weekend. That change is genuine, and pretending otherwise would insult you.

Judgment did not collapse. Generic prompts produce the generic layer, the same paragraphs a chatbot hands everyone in your field. Making the output carry your experience, your cases, and your taste takes your hours again. They get spent at the exact place they were scarce.

So the branch is viable for a specific owner. One with steady weekly hours, a standard they can enforce alone, and some appetite for the work. The hours remain the price. When your pipeline stalls every time client work gets busy, this branch has answered you.

The in-house branch buys a person before it buys an outcome

Salary boards put the average marketing manager between roughly $83,000 and $105,000 a year. That is before benefits, tools, and any media budget, and it buys the average manager.

One person running strategy, writing, search, email, and social at your standard is a senior generalist. Senior generalists are scarce, they cost well above the average, and the good ones have options. Your firm is competing for them against companies with marketing departments to offer.

Hire junior instead and you have purchased a different job: managing a marketer. The direction has to come from somewhere. In a firm without a marketing leader, it comes from you. Those are the hours you were trying to buy back.

Recruiters who place these roles describe the failure pattern on repeat. The first hire gets chosen on a feeling, judged on activity, and replaced inside a year or two.

The branch pays off at volume. When the work fills a good person's week, every week, in-house wins on cost and on context. A usable threshold: when your whole marketing budget sits near one loaded salary, the hire is premature.

The agency branch has a floor, and the floor is attention

Selective shops publish minimum engagement levels, because a small account cannot be served well at their cost structure. Fall under those minimums and your inquiry routes, by default, toward the volume end of the market.

There, your fee divides across a stack of accounts. That arithmetic decides your service level before anyone opens your file. Below meaningful spend, you are nobody's priority client, whatever the proposal says.

Above the floor, the branch buys things the other branches cannot. A team across channels. Continuity when one person leaves. Depth in paid media and technical work that no single hire matches. For defined channel execution at committed spend, an agency is often the right machine.

One constant survives every spend level. An outside team's default output is the generic layer, because the generic layer is what they hold. An engagement that never asks for your time and your stories has priced generic work into the quote. No fee removes that constant, on any branch, because your experience is the one input money does not supply.

Three numbers resolve the fork

Spend first. A thin budget puts the selective end of the market out of reach. The volume end then becomes a known outcome. The branch then narrows to you plus tools, aimed at few things done well.

Hours second. A calendar that cannot hold steady weekly marketing hours ends the DIY branch, whatever the tools promise. AI multiplies the hours you give it. It does not replace them.

Standard third. A presence meant to carry a national ambition fails on junior execution, in-house or out. Taste and judgment are senior skills, and they are the expensive part on every branch.

Run all three and an established expert firm usually lands in the same place. Enough budget to be a priority somewhere. Too few spare hours for DIY at a serious cadence. A standard that requires senior hands. The remaining question is whose senior hands: an agency team, assembled freelancers, or one practitioner. That comparison has its own answer.

Whichever door you choose, the vetting is identical. Ten questions put to any provider before signing surface the engagement's structure, including mine.

Where each branch wins

Doing it yourself wins early, at low stakes, for an owner who writes well and holds the hours. Some owners keep it permanently because they like the work, and it shows in their voice. That is a legitimate ending, and cheaper than every alternative.

In-house wins on constancy. When marketing fills a good person's week all year, the hire beats a retainer. The context an employee accumulates compounds year over year.

An agency wins on team-shaped problems at committed spend. Think paid media, multi-channel execution, and jobs where continuity beats intimacy.

And every branch shares a ceiling. The marketing tops out at the depth of your own input, because nobody you hire has lived your cases. Whoever does the work, plan on supplying the raw material.

The numbers you already hold

Write down three numbers tonight. The budget you will commit for a year. The weekly hours you can hold for a year. The standard your name requires, stated as the firms you want to be mistaken for.

Price each branch against all three, the way this page did. The branch that survives is your answer, and the vetting starts after.
