Overview
- Social media marketing for law firms produces signed cases in some practice areas and almost none in others, and the difference comes down to whether people decide to hire you before they need you or after.
- Personal injury and criminal defense get most of their social value from short video that builds recognition ahead of the emergency, while estate planning and business law get theirs from long form credibility and referral relationships.
- Facebook still outperforms Instagram for estate planning and family law because of who’s on it, and LinkedIn is the only platform worth serious effort for B2B and referral driven practices.
- Running one platform well beats running five badly by a wide margin, and the bar advertising rules mean your posts and your paid ads both count as attorney advertising.
A criminal defense firm I know posts one 45 second vertical video a week explaining something specific, like what happens at a bond hearing in their county. No dancing, no trends, shot on a phone in the office. They sign three to five cases a month from people who say they’d seen the videos before they got arrested. That’s social media marketing for law firms working exactly the way it’s supposed to.
An estate planning firm doing the same thing on the same platform would get nothing. The mechanism is completely different, and that’s the part most advice skips.
The rule that decides which platform is worth your time
People hire a PI or criminal defense lawyer in an emergency. They’re not browsing. They’re searching, and they’re searching now. So social can’t capture that moment, it can only pre load it, which means recognition. They saw your face forty times over a year, and when the emergency hits, you’re the name they think of before they open Google.
Estate planning, business law, and most family law work differently. Nobody’s ever in an emergency about a revocable trust. The decision is slow, it’s often prompted by someone else (an accountant, a financial advisor, a friend), and it rewards credibility and trust built over time. That’s a different content type and often a different platform entirely.
Get that backwards and you’ll spend a year making content that can’t possibly work.
Practice area by practice area
Personal injury
Short vertical video, and mostly paid amplification rather than organic reach. The goal is name recognition in a defined geography, not engagement. Facebook and Instagram Reels, targeted tightly to your service area.
What works: explaining the things people get wrong right after a wreck, what the insurance adjuster’s call really is, what your fee actually covers. What doesn’t: case result posts, which mostly attract other lawyers and run straight into advertising rules.
Honestly, for most PI firms under $5M, social is the fourth thing to fund, well behind search. Our personal injury lawyer marketing page lays out the order.
Criminal defense
The best social fit of any practice area, and the most underused. Your prospects are researching in fear at 2am, often on a phone, often for someone else. Short video that explains process, plainly, with no judgment, converts unusually well.
TikTok and Instagram Reels both work here because the audience skews younger. Post consistently for six months before you judge it. This pairs well with search intent work, and what people Google right after getting arrested is a good source of topics. Broader strategy sits on our criminal defense marketing page.
Estate planning and elder law
Facebook, and it isn’t close. The platform’s core user base is the demographic making estate planning decisions, and Facebook’s targeting still lets you reach people in your county by age. Instagram and TikTok are a waste of your hours here.
What works: longer posts, local group participation where it’s permitted, and event promotion for seminars or webinars. Paid Facebook to fill a seminar seat is one of the few genuinely reliable paid social plays in legal, and the math holds up when the seminar actually converts. See estate planning marketing for how that fits with everything else.
Family law and divorce
Mixed. Facebook works for the reach, but family law prospects are private about their situation and won’t like, comment, or share anything that tells their network what’s happening. So engagement metrics will look terrible while the content still does its job.
Write for the lurker. Useful, calm, no drama, no “ready to fight for you” energy. Measure by direct traffic and branded search, not by likes. More at family law marketing.
Business law, employment, and anything B2B
LinkedIn, and only LinkedIn. Your prospects and, more importantly, your referral sources are there. One thoughtful post a week from the attorney’s personal profile beats anything the firm page will ever do. Firm pages on LinkedIn get almost no reach and always have.
This is the one place where social reliably produces real matters directly rather than through recognition. Details in LinkedIn marketing for attorneys.
The platforms most firms should drop
X, for nearly every firm. The legal audience there is other lawyers.
YouTube as a primary channel, unless you’ll commit to weekly video for two years. It’s excellent when you do. Most firms quit at video nine.
Pinterest, Threads, and whatever launched last quarter. If someone’s pitching you on a new platform, the answer is no until your one good platform is running.
Firm-branded Instagram accounts that post office birthdays and holiday graphics. That’s not marketing, it’s a chore with a login.
The bar advertising rules, in plain terms
Your state bar treats your social posts as attorney advertising. Not just your paid ads. The organic post too, and in most states the profile bio counts as well.
The constraints that come up most:
Case results need context. A post about a seven figure verdict generally requires a disclaimer explaining that results depend on the facts of each case, and some states want specific language. Check your own rules before you post the number.
Testimonials are restricted in many states, and in some they’re prohibited outright for certain claims. A client posting a review on your Google profile is different from you reposting it as an ad. The repost is advertising.
No claims of specialization unless you’re certified in that specialty by an approved body. “Expert in personal injury” in your bio is a problem in a lot of states.
Comments are part of the ad. Answering a specific question in a comment thread can create the appearance of an attorney client relationship or of giving legal advice. Keep answers general and move the conversation to a call.
Targeted paid social aimed at people likely to need a lawyer right now can run into direct solicitation rules in some jurisdictions. This is the one to actually ask your bar about before you run it.
I’m deliberately not citing rule numbers here because they vary by state and they change. Pull your own state’s advertising rules and read them once. It takes an hour and it’s the cheapest insurance available.
One platform, done properly
Here’s the part most firms resist. Pick one platform, post to it consistently for six months, and ignore the rest. Five accounts posting twice a month each produces nothing anywhere. One account posting twice a week builds something.
Consistency beats production value by a wide margin. A phone camera, decent audio, and a real answer to a real question will outperform a $3,000 video shoot you make once and never repeat. Budget wise, most small firms should spend $0 to $500 a month on social production and put the rest into search. If you’re running paid social, $500 to $2,000 a month is enough to learn whether it works in your market.
And measure it correctly. Social almost never gets last click credit, because the person sees your video in March and searches your firm name in July. Watch branded search volume in Google Search Console and ask every intake “how did you hear about us.” If branded searches are climbing, it’s working, whatever the engagement numbers say.
