Law firm marketing agency vs in-house: which fits?
Hire in-house when you've got enough marketing work to fill a real job and someone to manage it. Use an agency when you don't. Most firms under about fifteen lawyers have five hours of work a week spread across six different skills, which is the shape an agency fits.
You're choosing between a person and a team, and the money is closer than it looks. A full-time marketer costs a salary plus payroll taxes, benefits, software licences, and the hours you spend managing them. An agency costs a monthly fee. When you compare a law firm marketing agency vs an in-house hire, the interesting part isn't which is cheaper — it's what each one is actually good at.
The short answer
Hire in-house when you have enough marketing work to fill a real job, and someone to manage it. Use an agency when you don't.
Most firms under about fifteen lawyers don't have forty hours a week of marketing. They have five, spread across six different skills — writing, design, ads, SEO, reporting, and chasing the website developer. That's the shape an agency fits.
What in-house genuinely wins at
Say this part properly, because it's real and most agency posts skip it.
They're in the building. A marketer who sits near you hears the cases you're excited about, notices when a client says something quotable, and catches the thing you'd never think to put in a brief. No agency gets that by osmosis.
Speed on small things. "Can you change the headline on that page" takes thirty seconds if the person is down the hall and a day if it goes through an account manager.
They learn your practice. After a year, a good in-house marketer knows your practice areas well enough to write about them without a briefing. That's genuinely valuable and it compounds.
Nothing is shared. Their whole week is yours. An agency splits its attention across clients by design.
If you can afford one, can keep them busy, and have someone who will actually manage them, in-house is a good answer. Plenty of firms should take it.
What an agency wins at
Breadth. Marketing isn't one skill. The person who writes well is rarely the person who runs ads well, who is rarely the person who fixes your site speed. One hire gets you one of those and a beginner's grasp of the rest.
No hiring risk. If the hire doesn't work out you've lost months and a salary. If an agency doesn't work out you cancel.
It scales down. Slow quarter, or you took on a big case and want to pause? You can't put a salary on hold.
You don't have to manage it. This is the one firms underrate. An in-house marketer without direction produces activity, not cases. Someone has to set priorities, review work, and decide what gets cut — and in a small firm that someone is a partner who bills by the hour.
Agency or in-house: the question that actually decides it
Not cost. Two things:
1. Is there forty hours a week of work? Write down what you'd actually want done in a month. For a small firm, the list often looks like this:
- Four blog posts about your practice areas
- Ad management in Google and Meta
- Review chasing after every case
- A few page updates on the firm website
- A monthly marketing report
Be honest about the hours. If it's ten, you're hiring someone to be underused, and underused people either leave or invent work.
2. Who's managing them? If the answer is "they'll manage themselves," that's not an answer. A marketer with no brief will pick the work that's most visible, which is usually social media, which is usually not what signs cases.
Managing also costs money, because it is partner time. Here is example math. Say a partner bills $300 an hour and spends 2 hours a week directing an in-house marketer:
Example numbers only. Use your own billing rate and your own honest guess at the hours. That amount sits on top of the salary.
If you can answer both, hire. If you can't, an agency is doing the managing for you, and that's most of what you're paying for.
Agency vs in-house, side by side
Here is everything above in one place.
| In-house marketer | Marketing agency | |
|---|---|---|
| What you pay | Salary, payroll taxes, benefits, software, and partner hours to manage | A monthly fee |
| Skills | One person, usually strong in one skill | A team across writing, design, ads, SEO and reporting |
| Knowledge of your firm | Grows every month; hears about cases first-hand | Only what you tell them |
| Speed on small changes | Minutes, if they are down the hall | Often a day, through an account manager |
| Who manages the work | Someone at your firm, often a partner | The agency |
| If it doesn't work out | Months and a salary lost | You cancel |
| Slow quarter | The salary stays the same | You can scale down or pause |
| Best fit | Forty hours a week of work and a clear manager | A few hours a week spread across many skills |
One rule applies either way. Law firm advertising has to follow your state bar's rules. Most states base theirs on ABA Model Rule 7.1[1] on false or misleading claims. An in-house hire or an agency writing your ads needs to know them, and you still sign off on the final copy.
The third option
There's a version nobody sells you, because there's no money in it: do the basics yourself and buy nothing.
Ask every client for a review. Answer the phone. Keep the website accurate. A solo practice with a steady referral base can run on that for years, and plenty do. It costs you an hour a week and no money at all.
It stops working when you want growth on a schedule rather than whenever it happens. But if you're not there yet, be honest that you're not there yet.

What most firms actually end up doing
A version of both. Someone inside the firm — often an office manager or a paralegal with an interest — owns the parts that need firm knowledge: which cases to talk about, what sounds right, chasing reviews. Everything technical sits outside.
That works well and it's cheaper than either pure option. The failure mode is when nobody owns the inside half, and the agency is left guessing what the firm actually does.
Where we fit
We're the outside half. The website, on-page SEO, the review funnel, missed call text back and follow-up run without anyone at the firm remembering them. What we can't do is know which cases you want more of — you tell us that once, and it shapes everything after.
Then it's monthly. What came in, what it cost, what to keep and what to cut — and refine it again next month. If you hire in-house later, the system stays and they inherit it rather than starting over. The full picture for legal is on the law firm digital marketing page.
Questions firms ask about agency vs in-house
What is the difference between in-house and agency marketing?
In-house is one employee who works only for you. An agency is a team that splits its time across clients. In-house gives you control and firm knowledge; an agency gives you a wider set of skills and no hiring risk.
What are the drawbacks of in-house marketing?
One person can't be good at writing, design, ads and technical SEO all at once. You carry the hiring risk if it doesn't work out, you can't scale the cost down in a slow quarter, and somebody at the firm has to manage them.
Is in-house better than an agency for a law firm?
It's better when you have enough work to fill a real job and someone to direct it. Most firms under about fifteen lawyers have five hours of marketing a week spread across six skills, which is the shape an agency fits.
How much does a law firm marketing agency cost compared to hiring?
Compare total cost, not headline cost. A hire is salary plus payroll taxes, benefits, software and the partner hours spent managing them. An agency is a monthly fee. Ask both for the number in writing before you compare.
Can I do both?
Most law firms end up with a mix of agency and in-house. Someone inside owns the parts needing firm knowledge — which cases to talk about, what sounds right, chasing reviews — and everything technical sits outside. It fails when nobody owns the inside half.
