The Proposal Lists Six Services. The Seller Uses Almost None of Them.
Part 4 of a series on what the marketing industry's own numbers say about buying growth.
A proposal sits on a firm owner’s desk with six line items: SEO, paid search, social media management, content, email, directory management. Each line carries a monthly figure, and together they describe a growth engine. The same week, across town, the agency that sent it holds its own new-business meeting. None of the six line items is in the room. The pipeline under discussion runs on referrals from past clients, a partner firm that sends work, and a conference talk the founder gave in the spring. The renewal will take ten minutes to sign.
The number doing the work in that signature is the menu itself. The implied claim under every line item is that these services are what produces clients, and the proof on offer is that a company in the business of growth chose to sell them. The signature is being applied to the menu’s claim about causation.
Here is what the menu actually measures. Two things, in the same cell. The first is what the agency’s labor base can produce: the deliverables its headcount was hired to ship. The second is what produces clients. The menu reports the first and is silent on the second. There is one document in the file that reports the second, and it is the one the firm owner never sees: the seller’s own marketing budget.
The industry surveyed itself on that document, and the comparison can be run line by line.
SEO is sold as the core retainer, with standard guidance steering 45 percent of a law firm’s digital budget toward it as the highest-return channel, per the LEXGRO aggregation. In SparkToro’s survey of 376 agency owners, it is absent from the top drivers of the agencies’ own new business.
Paid search is sold as the fast lever, at legal click costs running $80 to $200 and an average of 13.4 leads to convert one client, per National Law Review and Martindale-Nolo figures. It is essentially absent from the sellers’ own acquisition stack, and the paid formats agencies do buy for themselves, networking events and industry awards, sit at the bottom of their own effectiveness rankings.
Social media management is sold as a standard line item. In the same survey, 20 percent of agencies say social media is no part of their own marketing at all, and the platforms dropped down their rankings as a source of business. The exception proves the shape: among agencies that do use social, 73 percent name LinkedIn most effective, and what works there is the founder writing under their own name, which is a different product from managed multi-platform posting.
Outbound lead generation is sold as intake campaigns and cold outreach programs. 59 percent of agencies have run it on themselves. 9 percent call it very effective. 33 percent call it not effective at all.
Content is the partial exception, and the honest version of this essay says so. Agencies genuinely use it. What they use is founder authority content and conference speaking that feeds the referral engine, produced by the founders themselves, since 79 percent of agencies have no one dedicated to their own marketing and 70 percent have no full-time salesperson. Volume content built for rankings, the version on the proposal, is a different product wearing the same name.
And the document has a bottom line. Asked what actually produces their new business, the sellers answer: referrals from past clients first by a wide margin, referrals from partner firms at 15 percent, founder content, and event speaking, which climbed from sixth to fourth in a year. In the broadest survey of the field, 93 percent of firms in the business of selling growth call their own growth engine weak. The engine that runs the category is relationships and reputation. The engine on the proposal is the six line items.
Read the seller’s allocation as what it is: the honest survey. An agency answering a questionnaire is describing itself; an agency spending its own money is revealing what it believes produces clients, at its own price, with its own margin at stake. What they buy for themselves is the belief. What they sell is the capacity.
The counterweight, because the honest claim is narrower than the satisfying one. The gap is incidence, not hypocrisy. Agencies buy against their own binding constraint, and for a referral-run professional service that constraint is relationships and reputation, so their budget goes there. A firm whose binding constraint is genuinely retail demand, high-volume consumer work in a market of strangers, may rationally buy tactics the seller does not buy for itself. The gap does not convict any line item. It convicts the menu’s claim to universality: the assumption, priced into the signature, that what the catalog contains is what any firm’s growth requires. That assumption is exactly what a binding-constraint read exists to test, and the sellers have never run one on themselves.
The reader can’t see the agency’s books, so the mirror can’t be checked directly. One question substitutes for it, asked before the renewal: which of these line items do you buy for yourselves, at your own price, and what did each one return. A shop that made its own allocation on evidence can answer in numbers, and the numbers will be interesting whatever they show. A shop that can’t answer is selling capacity in a growth costume, which is the same finding Part 2 reached from the other side of the table.
The two documents now have names. The proposal is the labor panel read out loud: what the headcount can ship, priced by the month. The seller’s own budget is the demand panel kept private: what the seller believes produces clients, priced with its own money. The series opened on the gap between those panels, and this is the gap completed. Before the next renewal, the number that prices any line item against the firm’s own economics is the one this series has been circling: contribution per owner hour. The Growth Intelligence Scorecard computes it in about four minutes, from your own figures, in ranges, from memory, and names the binding constraint. Free, at growthprolegal.com.
Next week, Part 5, the last in the series, written to the other side of the table: the agency owner, whose books show what the obligation to perform marketing costs.
This issue is an economic diagnosis of a firm as a business. It is not legal advice and not the practice of law. It works from published industry data stated in ranges, is not a reconciliation, and is not accounting advice or a substitute for the firm’s accountant. It is not a valuation and not investment advice.
