A guide for M&A firms on picking an agency that builds direct deal flow, respects NDAs, and keeps bankers and CPAs sending referrals.
Why a generalist agency struggles with M&A deal flow
Most law firm marketing is built around a client finding the firm directly and calling. M&A work has historically run the other way: investment bankers, business brokers, CPAs, and wealth managers hand off legal work to counsel they already trust, which is a referral engine entirely outside your firm's control from one quarter to the next. An agency that only knows how to run ads has no plan for the referral half of your pipeline, and a firm that relies on referrals alone has no plan for the quarters when the phone from those sources goes quiet.
The second thing generalists get wrong is confidentiality. A business owner exploring a sale is often keeping it secret from employees and customers, and live deals sit under NDA that limits what a firm can show publicly. An agency used to publishing client names and dollar figures as proof of results simply cannot do that here, and one that tries risks a professional-conduct problem, not just an awkward page.
Third, deal size matters more in this niche than almost any other legal category. A firm built around $1 million to $500 million transactions gets very different inquiries than a firm chasing every small business sale in town, and an agency that cannot tell a $150,000 asset sale from a real platform acquisition will fill your intake with calls that eat partner time without ever becoming the engagement you actually want.
The first qualifying question to ask any agency
Ask this on the first call: 'How would you build direct search and ad channels that bring owners and buyers to us without depending on a banker remembering our name?' The answer shows whether an agency actually understands that referrals, while valuable, cannot be the whole strategy.
A good answer talks about ranking for searches like 'attorney to sell my business' and explaining deal mechanics, letters of intent, due diligence, reps and warranties, escrow, and earnouts, in plain language a first-time seller can follow. If the agency only wants to talk about a generic 'corporate law' page, they have not thought about how a first-time seller actually evaluates a firm.
Also ask how they would keep your firm visible to the bankers, brokers, and CPAs who send you deals today. An online reputation strong enough for a referral source to check before sending their client your way is a distinct piece of work from a paid search campaign, and an agency should be able to describe both.
Which channels actually produce signed engagement letters
Google Ads built around sell-side and buy-side searches, things like 'business acquisition lawyer near me' and 'letter of intent review attorney', reach owners and buyers at the exact moment they are ready to talk, with every call tracked back to the keyword that produced it. This channel works fastest when an exclusivity period or a financing contingency puts a real clock on the deal.
SEO and deal-process content do the quiet work that referrals cannot replace. An owner who has never sold a business before searches for basic explanations of the process long before they call anyone, and content that ranks for those searches while explaining the mechanics builds trust before the first conversation even happens. That same content is often what a banker points a client toward when making a referral.
AI search visibility is becoming part of how both owners and referral sources vet a firm, so being the name an assistant surfaces when someone asks who handles business sales in your market matters more each year. Finally, follow-up email keeps your firm in front of bankers, brokers, CPAs, and past clients between deals, so your name is still top of mind the next time one of them has a seller ready to move.
The real numbers: deal timing, not seasonality
M&A work does not run on a yearly season the way a retail business does. What actually drives timing is a sale process clock, an exclusivity window, a financing contingency, or a retirement-age owner finally deciding to explore an exit. A firm that responds slowly to any of those moments loses the engagement to whichever firm called back first, regardless of who is actually better at the work.
The number that matters most here is cost per qualified inquiry, not raw lead volume. A significant share of inbound calls in this niche are for deals too small to be worth partner time, so screening for deal size and seller intent protects the pipeline as much as the ad budget does. An agency that only reports total leads without separating real platform-sized deals from small asset sales is not giving you a useful number.
Ask how an agency would track a call all the way from first contact through a signed engagement letter, including whether it came from a referral source or direct search. Without that tracking tied to actual deal size, you cannot tell whether last quarter's marketing spend brought in the engagements you actually wanted.
Red flags and the ownership questions that protect your firm
Watch for any agency that wants to publicize deal details, name clients, or reference specific transaction terms as proof of results. Confidentiality obligations and professional-conduct rules make that a real risk, not just bad form, and a firm doing that work correctly should never suggest it.
Ask plainly who owns your website, your ad accounts, and your client and inquiry data. If an agency builds your site on a platform you cannot leave or runs your ad accounts under a login only they control, walking away later means losing everything you built. Every asset should sit in your firm's name.
Also watch for a generalist package that markets your firm the same way it would market a personal injury practice, with no distinction between sell-side, buy-side, and general outside counsel work. A specialist agency will build separate content and campaigns for each of those, because the searches, the language, and the referral sources behind them are genuinely different.
Six questions to ask before you sign with an agency
Ask these in order and compare answers side by side. One: how would you build direct search traffic without replacing our referral relationships? Two: how would you explain LOIs, due diligence, and reps and warranties to a first-time seller in plain language? Three: how do you screen deal size before an inquiry reaches a partner? Four: how do you respect NDA and confidentiality obligations in the content you write? Five: do we own our website, ad accounts, and data, and what happens to them if we part ways? Six: how would you build our reputation with the bankers and CPAs who refer us clients?
Specific answers to all six tell you whether an agency has actually worked with deal counsel before.
