Vertical Playbooks

How each kind of business gets found and chosen, on its own terms.

The rules of visibility change by trade. A med-spa is named for a treatment; a plumber for a neighbourhood and a fast answer; a law firm for a practice area, inside advertising rules. This line reads each vertical on its own terms: how its buyers actually search, what earns their trust, and where the independent still wins.

Attorney Advertising and AI Answers: What Rule 7.1 Permits and What Search Visibility Requires

A synthesized answer that summarizes a firm's practice areas is a communication about a lawyer's services, and it can carry the same "reasonable factual foundation" exposure a billboard does. A reading of Rule 7.1 and the 2024 FTC review rule against the surfaces where legal buyers now decide.

One Verifiable Identity: Why Your Bar Profile Is the Record an AI Engine Actually Trusts

An engine deciding who to cite needs to resolve a firm to one confident, licensed entity. Fragmented name, address, phone and bar-number data across a firm site, its Google Business Profile, and the legal directories actively works against that, and so does schema built to a markup type Schema.org has since deprecated.

The Practice-Area Page Beats the Generalist Homepage: What Legal Search Actually Rewards

Specificity, not breadth, is what both classic local search and generative-engine citation reward. A single page built around one matter and one county consistently reads as more relevant than a homepage listing nine practice areas, to a person and to a model.

The Response Chasm: Why Law Firms Lose the Clients Their Marketing Already Won

For a meaningful share of firms, the constraining problem is not visibility, it is what happens in the minutes after a ready client makes contact. A field test found most firms fail a simple response test, and the case for why that matters is one of the most established findings in lead-response research.

Why Three Out of Four Legal Searches Now End in an AI Answer, Not a Click

Legal is one of the most AI-Overview-exposed search categories measured. The mechanism that follows, a summary present, then a sharp drop in clicks to any result, is independently confirmed outside legal specifically. Being ranked is necessary but no longer sufficient.

Anyone Can Legally Prepare Your Taxes: What the PTIN System Actually Verifies (and Doesn't)

Tax-return preparation is largely unregulated at the federal level. Unenrolled preparers filed more individual returns than CPAs and enrolled agents combined in the most recent public breakdown, and ghost preparers are a recurring, IRS-named fraud warning. The credential most buyers never check is the one that matters most.

The Sprint and the Marathon: Why Tax Season and Bookkeeping Need Two Different Visibility Plans

Search demand for tax preparation swings up to 7.4x seasonally while bookkeeping and advisory demand stays essentially flat all year. Running one undifferentiated marketing motion for both means overspending on one and starting the other too late.

Why 57% of People Find Their Accountant Through a Friend, and What That Means for Everyone Else

Accounting is one of the most referral-dominated, least-advertised-into professional categories measured. That leaves most firms with no review system at all, a widening gap against the growing share of buyers who now check reviews and ask AI for a recommendation first.

Accounting and Tax: The Credence Gap AI Hasn't Closed

Tax and accounting clients cannot verify the work they are buying, so they lean on reputation and credentials instead of price, and even fast-growing AI adoption for filing has not closed that trust gap.

Fitness and Wellness: How Members Actually Find a Gym in a Record Year
