Hiring a legal SEO agency is mostly an exercise in pattern recognition. The good agencies say specific things in specific ways. The bad ones — the ones that will take your money for a year and produce nothing — also say specific things in specific ways. Once you know what to listen for, the evaluation isn’t hard. The hard part is making yourself slow down enough to actually listen.
The Legal SEO long-form guide lists seven questions to ask in the sales call. That’s the start. This page is the whole process — how to read the sales deck, what a real case study looks like, how to run a reference call that’s actually useful, what to push back on in the proposal and the contract, and how to structure the first ninety days so you find out whether the engagement is working before the renewal happens.
Reading the sales deck critically
The first artifact you’ll see from most agencies is a sales deck. It is the most polished thing they will ever produce for you. Treat it that way. The deck represents the agency at its absolute best — the work was done by their best people, edited by their best designer, sales-engineered by their best salesperson. If the deck has problems, the operational reality is much worse than the problems.
Three patterns in the deck tell you most of what you need to know.
Pattern one — how specific is the diagnosis of your firm? A real agency, in a real sales conversation, has already spent two or three hours looking at your site, your competitors, and the SERPs in your market before they show up. Their deck includes screenshots of your actual practice pages with specific notes. It names your top three or four competitors by name and explains where they rank. It includes specific keyword examples where you are or aren’t visible. The diagnosis is firm-specific.
A bad deck is interchangeable. The deck you got is the deck the agency shows every law firm — generic methodology slides, a “Why SEO Matters” section, an “Our Process” diagram, a few unnamed case studies. The diagnosis is “law firms in general would benefit from SEO.” The proposal is the same one they’d send any firm. The customization is in the cover slide where they typed your name.
Pattern two — what’s the work, exactly? Real agencies describe their work in specific verbs. “We will rewrite seven practice pages. We will rebuild three of your top competitor’s link sources. We will fix four citation inconsistencies we already identified. We will set up call tracking and form attribution by end of month one.” The verbs are concrete. The deliverables are bounded.
Bad decks describe work in nouns and adjectives. “Comprehensive content strategy. Holistic link acquisition. Strategic on-page optimization. Authoritative content production.” None of these are work. They’re labels. If you cannot, after reading the deck, write down on a sticky note what the agency will actually do in month one, the deck is theater.
Pattern three — what does the agency say they will measure? The page on why most law firm SEO fails covers this in detail. Short version: if the measurement framework in the deck is built around traffic, impressions, rankings, or DA, you are looking at a vendor that intends to demonstrate effort, not outcomes. If the measurement framework is built around qualified calls and signed retainers attributed to organic search, you have a vendor that intends to be judged on the thing you care about.
What a real case study looks like
Every agency claims case studies. Almost none of them are useful as evidence. The fix is to know what a real one looks like, then ask for it.
A real legal SEO case study includes, at minimum: the name of the firm (or a defensible reason it’s anonymized — and “client confidentiality” is not a defensible reason unless the firm has explicitly asked, in which case the agency should be able to produce a few that aren’t anonymized too); the practice area; the city or markets; the starting state on specific named queries with screenshots from a tool like Ahrefs or Semrush, dated; the work that was done, in plain language; the ending state on the same named queries, with dated screenshots; and the case-volume change if the firm shared that data, with appropriate context.
What’s almost always missing from agency case studies is the specifics. “We grew their organic traffic 240%” is the most common case-study line in the industry, and it’s nearly useless. Traffic from where? On what queries? Did the new traffic convert? Did the firm sign more retainers? Did the firm’s revenue go up? Without those follow-ups, “240%” could mean the agency wrote a viral blog post about a celebrity scandal that produced massive low-intent traffic and zero new cases. That’s not hypothetical — I’ve seen exactly this in three different “case studies” presented to firms I later worked with.
“We grew their traffic 240%” is the most popular case-study line in legal SEO and the most useless. Traffic from where, for what, that converted into what?
When the agency shows you a case study, ask: “Can I see the rankings screenshot at start and at twelve months on the specific queries you targeted, and can the firm in the case study get on a fifteen-minute reference call?” Watch what happens. The good agencies will produce both. The bad ones will offer one or the other, or pivot to a different case study, or say the firm prefers not to take calls. The pivot is the answer.
Reference calls — who to ask, what to ask
Reference calls are the single highest-information artifact in the entire vetting process, and most firms either skip them or do them badly. Two problems usually. First, the agency picks the references, so you get the firms that love them — which is fine, but selection-biased. Second, the questions you ask tend to be polite and surface-level, which produces polite, surface-level answers.
The fix on the first problem is to ask for references the agency would not have given you by default. Specifically: “Can you share three references — one client who’s been with you longer than two years, one who joined within the last six months, and one who left at some point and stayed civil with you?” The two-year reference tells you what long-term retention looks like. The six-month reference tells you what early-engagement experience is like. The former-client reference tells you what disengagement was like — which is critical, because half of SEO engagements end at some point, and you want to know whether the breakup is professional.
If the agency cannot or will not produce a former-client reference, that’s data. If their explanation is “we don’t have any former clients we’d be comfortable putting forward,” it means either they have a high churn rate they don’t want to expose, or they end engagements badly. Both are useful to know.
On the second problem — what to ask — here are the questions that have actually produced useful answers in reference calls I’ve sat in on. Read them in order. Don’t read them off the page; pace them through the conversation.
- “Walk me through what month one of the engagement looked like for you. What did the agency actually produce in the first thirty days?”
- “Who was your primary point of contact, and how often did you talk to the person actually doing the strategic work on your account?”
- “At what month did you see the first real, measurable change in inbound calls or signed cases — and how did you know it was the SEO work?”
- “Was there a point in the engagement where you considered firing them? What was happening at that point, and what changed?”
- “If you were starting over, would you sign the same contract again? What would you negotiate differently?”
- “What’s the one thing about working with this agency that you’ve never seen written in their marketing?”
That last question is the most valuable one. It opens a window the agency cannot have prepared the reference to close.
Reading the proposal / SOW
If the deck passed, references checked out, and you’re now staring at a proposal or statement of work, this is where the most important decisions get made. The proposal is the document that defines what the agency is actually committing to do versus what you think they’re going to do. Many engagements fail in the gap between those two things.
Read the scope section three times. Underline every verb. Then list, on a separate piece of paper, what specifically the agency will produce in months one, two, and three. If that list is mostly verbs like “manage,” “optimize,” “monitor,” or “support,” the scope is unbounded. The agency has not committed to a quantity of work. The scope is whatever it ends up being.
A good scope reads more like: “Month 1 — comprehensive audit; rewrite of practice pages X, Y, and Z; setup of call tracking and form attribution. Month 2 — rewrite of pages A, B, and C; GBP audit and cleanup; citation correction across the major legal directories. Month 3 — review-velocity program launch; build out of two new sub-practice pages; second pass on the highest-traffic page from month one.” You can hold them to that scope. You cannot hold them to “we’ll optimize your site.”
Contract clauses to push back on
The contract is the asymmetric document. Most agency contracts are written to protect the agency. That’s not unreasonable — it’s their contract — but it means the firm has to push back on specific clauses if they want a fair deal. Three clauses matter most.
Term length and auto-renewal
The industry default is twelve months with auto-renew unless cancelled with sixty or ninety days’ written notice. Push for month-to-month. If the agency cannot accept month-to-month, push for a six-month initial term with no auto-renew — meaning month seven is opt-in, not opt-out. If the agency cannot accept that either, you are dealing with an agency whose business model is built on retention through contract length, not retention through results. Decide whether that’s a deal you want.
Exit fees are a related landmine. Some contracts include early-termination fees of 50–100% of the remaining contract value. Strike them. If the agency will not strike them, you’ve learned that they don’t expect to keep you happy enough to want to stay voluntarily.
IP ownership of content
This one bites firms every year. Many agency contracts include clauses that retain the agency’s ownership of content produced during the engagement — practice page rewrites, blog posts, anything the agency wrote. If you cancel, the agency reserves the right to require you to remove their content from your site. Some go further and reserve the right to charge a one-time fee to “release” the IP.
This is unacceptable. Strike it. The content you paid the agency to produce should be yours. Push the contract toward “work product produced under this engagement is owned by the firm upon payment in full.” If the agency resists, walk. There is no defensible reason for the agency to retain ownership of work you paid for.
Conflict of interest
Add a clause if it isn’t there. Something like: “The agency agrees not to take on another law firm client in [specific practice areas] within [geographic market] for the duration of this engagement plus six months thereafter.” This protects you from the agency optimizing the search results in your market on behalf of a direct competitor. Some agencies will accept this. Some will not — they’ll say it limits their business too much. Their answer tells you something either way.
Red flags that show up in the proposal itself
Before you sign anything, scan the proposal for these specific patterns. Each one, on its own, is a flag worth pushing on. Two or more in the same document is usually a “walk.”
- Bundled services (SEO + PPC + social + web). You’re hiring a specialist or you’re hiring a generalist. Bundles are the latter dressed up as the former.
- “Up to” language on deliverables. “Up to 25 backlinks per month.” That’s a maximum, not a commitment. The actual number could be zero.
- Page-one ranking guarantees, or any guarantee tied to a specific position. No reputable SEO promises this. Anyone who does is selling something other than SEO.
- Pricing tiers with bronze/silver/gold packages. Your firm’s work is specific to your firm. Tiered packages exist to make pricing easier on the agency, not to deliver outcomes.
- Vague “consulting hours” line items. “20 consulting hours per month.” Doing what? With whom? Toward what outcome?
- Pass-through fees not itemized. Some agencies bill you for “directory submissions” or “premium tools” at marked-up rates without telling you what’s actually being paid for.
- Required minimum commitment lengths over six months. The good ones don’t need it. The ones that do are telling you their business model depends on you not being able to leave.

Structuring the first ninety days as a trial
No matter how much vetting you do, the only real test of an agency is the work itself. The smartest move is to structure the first ninety days as an explicit evaluation period — with both sides knowing it’s the evaluation period — and to define in advance what “passing” looks like.
Three things to negotiate into the start of the engagement:
A defined month-one deliverable. Not a generic “audit.” A specific, written one-page plan that names the three or four highest-leverage things to do in the next ninety days for your firm specifically. The plan is yours to keep regardless of whether the engagement continues. This forces the agency to commit a senior person to your account at the start — not after the contract is locked in.
A measurement framework, agreed in writing, before work begins. Call tracking installed. Form attribution configured. Starting baselines documented for inbound calls, form submissions, and (if you can share) signed retainers from organic search. The agency commits to reporting against these numbers monthly, not against DA or impressions or “engagement.”
A ninety-day review, with the senior strategist on the call. At month three, you sit down with the actual strategic decision-maker and review what was done, what moved, and what didn’t. If the engagement is working, you renew. If it isn’t, you have an honest conversation about whether the agency wants ninety more days to demonstrate it can move the needle, or whether you should part ways professionally.
This kind of structured trial only works if your contract is month-to-month or has a defined opt-in renewal at month four. If the contract is a twelve-month auto-renew, the ninety-day review is theater — you’re locked in regardless of how it goes. This is the structural argument for refusing the twelve-month contract.
A note on how we’d run this conversation
We’re month-to-month, no contract, no exit fees, owner-led — every part of this page is what we built our model around. The full philosophy is here, how we charge is here, and the owner story is here if you want to see who you’d actually be working with before you reach out.
If you’re in the middle of vetting agencies and want a second set of eyes on a proposal you’ve been sent, that’s a conversation I’ll have for free. No pitch attached. I’d rather you make the right call than the one that lands you with us by default.
