Business and corporate law firm marketing
Marketing for business and corporate law firms
Many business clients never search for a lawyer cold. They ask their banker, their accountant or another lawyer for a name, then look the firm up before they reach out. The marketing has to win both moments: the referral and the check that follows it.

The short answer
If you read one part of this page, read this.
Business law marketing works when the people who advise business owners know your firm, and when the firm looks established the moment a referred prospect checks it. For most corporate practices that means referral partners and reputation first, with paid search kept for the smaller, quick-need matters.
For one corporate client we built a referral-first plan around LinkedIn outreach and lined up six referral partners in six months, and those partners are still sending work. For a brand-new business firm we spent six months on a reputation build; now prospective clients and potential referral partners reach out on their own.
AI search and a credible website sit under both, because every referred prospect checks you before the first meeting. We work with law firms across the US and Canada, and also in Australia and the UK.
How business clients choose
They ask someone they trust, then they check you.
Sophisticated buyers rarely pick a business lawyer from an ad. They ask a banker, an accountant or another lawyer for a name, and the firm's online presence either confirms that recommendation or quietly undoes it.
- The referral comes first
A founder raising money, an owner selling a company or a finance lead with a contract dispute usually asks the advisers already at the table. Accountants and bankers often see these needs before any lawyer does, which is what makes them such useful partners.
- Then comes the check
The referred prospect searches the firm's name, reads the lawyer's LinkedIn profile and the Google Business Profile, and more and more often asks ChatGPT about the firm. A thin site or a profile with two reviews makes a strong referral look like a favor between friends.
- Two different buyers
A company that wants ongoing outside counsel compares firms over weeks and cares about who picks up when something goes wrong. A small-business owner who needs one contract reviewed this week searches Google and contacts whoever looks competent and answers.
- One client, years of work
A business client who stays brings formation, contracts, financing, disputes and, eventually, a sale. That recurring work is why one good referral partner can be worth more to a corporate practice than a month of ad clicks.
Channels that fit
Which channels fit a business law firm, and why.
We start with AI search and reputation, because every referral ends with someone checking you. Then we add referral-partner outreach, and paid search only for the matters business owners actually search for.
- AI search
When an accountant gives a client your name, the client often asks ChatGPT or Google's AI answers what they know about you. Those answers draw on your site, your Business Profile, reviews and mentions elsewhere, so a clear page for each kind of matter you handle (formation, buy-sell agreements, acquisitions, shareholder disputes) gives them something accurate to say. Our guide on how firms show up in ChatGPT explains how the tools pick.
- Reputation and the website
For a brand-new firm working across business, corporate and labor law, we spent six months on a clean presence, consistent positioning and credibility signals everywhere a prospect might look. Today prospective clients reach out unsolicited, and so do potential referral partners (the full story). A website that names the deals and disputes you handle does much of that work.
- Referral-partner outreach on LinkedIn
LinkedIn is where a corporate firm can find the bankers, accountants and other lawyers who already serve its ideal clients. For one corporate client, a referral-first strategy built on LinkedIn outreach produced six genuine referral partners in six months, with real relationships behind them, and they keep sending work.
- Local Services Ads
Google lists "Business lawyer services" and "Contract lawyer services" as Local Services Ads categories in the US. They suit the small-business owner with a quick, defined need, like a contract review or a new LLC, far more than a company choosing outside counsel. If you want them, start with getting Google Verified.
- Google search ads
Search ads fit specific, searched-for matters: a partnership dispute, a commercial lease, buying a business. Unlike Local Services Ads, you choose which matters to chase and block the rest. Our Local Services Ads vs Google Ads guide compares the two.
- Facebook and Instagram ads
Rarely the first move for a corporate practice. Business owners use these apps, but a cold ad is a weak stand-in for a banker's recommendation, so we test them only after referrals and reputation are working.
| Matter | Usually starts with | Why |
|---|---|---|
| Outside counsel for growing companies | Referral partners, reputation, AI search | Buyers ask advisers and compare firms over weeks |
| Acquisitions and business sales | Banker and accountant referrals, LinkedIn | Advisers see the deal before a lawyer does |
| Contract review, entity formation | Local Services Ads, Google search ads | Owners search with a quick, defined need |
| Partner and shareholder disputes | Google search ads, AI search | People search the problem by name, often under pressure |
Rules that shape it
Referral rules decide how you can thank the people who send work.
You can't pay a banker or an accountant for sending clients. You can trade referrals with them, as long as the arrangement isn't exclusive and each client is told about it.
- ABA Model Rule 7.2(b) bars giving anything of value for recommending a lawyer's services. The exceptions include the reasonable costs of advertising, the usual charges of a legal service plan or a qualified referral service, and nominal gifts that are neither intended nor expected as payment.
- Rule 7.2(b)(4) allows an agreement with another lawyer or a nonlawyer professional to refer clients to each other only if the agreement is not exclusive and the client is informed of its existence and nature. Minnesota's Rule 7.2(b) uses exactly this structure.
- Rule 7.3(b) bans live person-to-person solicitation for money. The exceptions include other lawyers, people with a close personal or prior professional relationship with the firm, and people who routinely use the type of legal services you offer for business purposes.
- Paying Google or LinkedIn for ads falls under reasonable advertising costs. Paying an individual per client they send does not.
For marketing, that means a referral program runs on relationships and reciprocity, not commissions. State versions differ, so check your own bar's rule before you formalize a partner arrangement. This is a plain summary for marketing planning, not legal advice.
Intake
Where business law firms lose matters after the inquiry arrives.
Business prospects are rarely in a panic, so the intake failures here are quieter: a referral that waits two days, a conflict found late, or a new matter nobody can trace back to its source.
Referrals that wait
A prospect sent by their accountant expects a quick reply, and the accountant hears about it when they don't get one. Reply the same day and, with the client's permission, let the referrer know you've connected.
Conflicts found late
Corporate matters have counterparties, and the other side may already be a client. Check every company and owner named before the first substantive conversation, not after the engagement letter goes out.
Small matters mixed in with large ones
Ads bring contract reviews and formations alongside bigger work. Two screening questions, on company size and matter type, send each inquiry to the right person and the right fee arrangement without slowing anyone down.
No record of who sent what
Track every new matter by source, down to the individual referral partner, or you can't tell which relationships deserve your time. Our follow-up and CRM work sets this up, and our guide to measuring law firm intake covers the numbers to watch.

FAQ
Questions business and corporate law lawyers ask us.
Straight answers to the questions that come up most.
Is LinkedIn worth it for a business law firm?
For finding referral partners, often yes. For one corporate client, LinkedIn outreach was the channel behind six referral partners in six months. It works when the outreach starts a real professional relationship, not when it pitches a service in the first message.
Can we pay accountants or bankers for referrals?
Not under ABA Model Rule 7.2(b) and the state rules built on it. You may trade referrals under a non-exclusive arrangement the client is told about, and give nominal thank-you gifts that aren't payment. Check your own state's version before setting anything up.
Do Local Services Ads work for business law?
For small-business matters with a quick need, they can. Google has US categories for business and contract lawyers. For outside-counsel work and deals, referrals and reputation usually carry far more weight. Our guide on what law firm marketing costs shows typical ad spend by platform, paid to Google on your own card.
How long does a reputation build take?
For one new business firm we spent six months on presence and credibility before prospective clients and partners started reaching out unsolicited. Paid search can bring inquiries sooner, but the larger corporate engagements tend to follow trust.
We're a new firm with no referral network. Where do we start?
Reputation first: a site that names what you do, a complete Business Profile and your first reviews. Then outreach to the advisers who serve the clients you want. The free Growth Guide suggests a starting point for your budget.
Do you work with business law firms in Canada?
Yes. Google doesn't list legal categories for Local Services Ads in Canada, so we lean on AI search, the website, Google search ads and referral-partner outreach. Canadian clients see the word "lawyer" everywhere.
