How to Choose a Law Firm SEO Agency

Every door has the same three letters on it

Shop for the best law firm SEO agency and you will notice something unsettling: the doors are identical. Searching "best law firm SEO company" returns ads and listicles written by the contestants, and behind them every lawyer SEO agency, every law firm marketing company, every generalist shop with a lawyers page — same three letters, same vocabulary of rankings and leads and growth, same case study carousel, same confident discovery call. The label is free — anyone can paint it on a door, and in a market with no licensing exam, roughly everyone has.

What separates one law firm SEO company from another is behind the door, and choosing an SEO agency comes down to four things: who actually does the work, what they measure, what they promise, and what happens when you leave. Those four questions organize everything that follows, from the specialization test to a full script of questions to ask before you hire an SEO agency — because vetting an SEO company is due diligence, and due diligence happens before you sign anything.

One disclosure before we start. We are a law firm SEO agency, and this is an article about how to choose one — a conflict of interest roughly the size of a highway billboard. So don't take any of it on faith. Apply every test in this article to us first, starting with who Eric St-Cyr and the team behind this agency actually are, and hold our answers to the same standard we are about to demand from everyone else.

The specialization test: do they work only with law firms?

The first sorting question is whether the agency is a legal SEO agency or a generalist agency with a legal page. A shop that ranks dentists, roofers, and restaurants can be genuinely competent at SEO and still be the wrong hire, because legal search is a different environment. Google treats legal content as YMYL — "Your Money or Your Life" — which means it holds law firm websites to a higher E-E-A-T standard than it holds a bakery. Legal advertising is regulated in ways restaurant marketing is not. And legal keywords sit in some of the most competitive markets in search, contested by firms spending five figures a month to stay there.

Niche specialization matters within legal, too. Personal injury lawyer SEO is a different sport from estate planning — different case values, different competition, different search behavior. Criminal defense marketing runs on urgency and mobile searches at 2 a.m.; family law runs on local trust signals and the map pack. An agency that pitches the same plan to a PI firm in Houston and a business lawyer in a mid-size market does not have a strategy. It has a template with your logo on it.

So ask what percentage of the agency's clients are law firms, and ask for the client list in your practice area specifically. A legal-only agency is buying you pattern recognition — it has seen your market's problem before and knows which levers moved. One caveat: specialization is necessary but not sufficient, and the niche has its share of mediocre specialists coasting on the word "lawyer" in their domain name. The antidote is knowing the work yourself — our complete guide to law firm SEO makes you a much more expensive person to fool.

Who actually does the work

The person selling you the campaign is almost never the person running it. Behind the pleasant account manager sits an org chart, and the org chart is where quality is decided. Some agencies employ their strategists, writers, and link builders in-house. Others are, functionally, a sales team with a markup: the actual SEO services for lawyers are fulfilled by offshore contractors or white-label wholesalers, and nobody in the building has read the content published under your firm's name.

Subcontracting is not a sin. Undisclosed subcontracting is. The vetting question is simple: who, by name and role, will touch my account, and which parts of the work are performed outside your company? Follow with the workload question: how many accounts does my account manager carry? An agency whose "dedicated" manager juggles forty clients has dedicated about two hours a month to you.

Content deserves its own interrogation, because content is where offshore fulfillment does the most damage. Every page an agency publishes for you is a legal communication with your name on it. Ask who writes it, what their qualifications are, and who reviews it for legal accuracy before it goes live. The right answer involves a documented review step — this is why we built our attorney-reviewed legal content writing process the way we did — and the wrong answer is any version of "our writers are very experienced" delivered without names.

Case studies: read them like opposing counsel

Every agency has proven results. The phrase is doing no work; the details either exist or they don't.

What a credible case study contains

A real case study names the practice area and the market, describes the starting condition, explains what was actually done, states the timeline, and reports outcomes in terms a managing partner cares about — qualified leads, consultations, signed cases — not just organic traffic curves. "300% increase in traffic" with no baseline, no market, and no client name is decoration, not evidence. Ask for two or three case studies in your practice area — the only proof of legal industry experience that counts — and be appropriately suspicious of a track record where every client is anonymous: some firms do request confidentiality, but all of them, every time, is a pattern.

How to verify a case study yourself

Here is the part no agency will suggest: check. Verification takes an evening and no special skills.

• Search the claimed rankings live. Open an incognito window, set your location to the client's market (or use any free rank-checking tool that lets you specify a city), and search the money terms. Either the firm is on page one or it isn't.
• Pull the traffic history. A trial account on Ahrefs or Semrush shows any domain's estimated organic traffic trend. The curve should match the story — and you can see whether growth survived after the screenshot was taken.
• Read the actual content. Visit the client's site and read three pages. Is this writing you would sign? Sloppy, generic content on the showcase client's site tells you what your site will look like.
• Skim the backlinks. The same tools show where a site's links come from. Legal directories, bar associations, local news, earned mentions — good. Link farms — walk away before someone else's black-hat tactics become Google penalties on yours.
• Call the firm. Lawyers take calls from lawyers. Five minutes with the managing partner is worth more than the entire case studies page.

References beyond the highlight reel

Then ask for client references the agency did not pre-select — two current clients not featured anywhere on its website. The client testimonials on an agency's own pages are curated by definition; references you choose are not. Ask what the first ninety days actually delivered versus what was pitched, how the agency communicated when results lagged, whether rankings turned into inquiries, and the question that summarizes the others: knowing what you know now, would you sign again?

Reporting: signed cases or a wall of green arrows

The monthly report is where you find out what an agency really thinks it sold you. Vanity metrics — impressions, raw traffic, search engine rankings for phrases with no commercial intent — make handsome monthly reports and pay no salaries. A report can glow green for a year while the phone stays silent, because ranking #1 for a question nobody asks is easy.

Transparent reporting ties the campaign to lead generation and, as soon as the data allows, to cases: qualified leads by source, consultations booked, signed clients, cost per case — the cost per acquisition and ROI figures that survive a partners' meeting. That requires call tracking and conversion tracking configured in the first month — an agency that doesn't set up attribution early is planning to be judged on traffic. Agree on the reporting cadence and communication channels up front, and insist on plain language. If you cannot explain your own SEO report to your partners, you cannot hold anyone accountable for it, which may be the point.

One structural rule: your Google Analytics, Search Console, and tracking accounts must be owned by the firm, with the agency added as a user. An agency that is the sole owner of your performance data controls the evidence in every future dispute, including the dispute about whether to fire them.

The scope checklist: what a full program includes

Law firm SEO services are not one activity; they are a bundle, and a missing component quietly becomes your problem later. A full-service program includes:

• A technical SEO audit — first. Crawlability, indexation, site speed, structural problems. An agency proposing content before anyone has audited the site is decorating a building without checking the foundation.
• Keyword research you can inspect, with search volume, difficulty, and commercial intent shown — not just a list of phrases with "lawyer" in them.
• On-page SEO across your practice area and location pages: titles, headings, internal linking, structured data, term coverage.
• Content marketing produced by people qualified to write about the law — attorney-written content where the stakes demand it, attorney-reviewed at minimum — on a stated monthly cadence.
• Link building and off-page SEO — legal directories, bar association profiles, digital PR, citations — with the sources named. "We do link building" is not an answer; it is the absence of one.
• Local SEO: Google Business Profile optimization, reviews strategy, and citation consistency, because for most firms the map pack is where the phone calls live — the mechanics are covered in our local SEO service for law firms.
• Reporting, as described above, as a deliverable in the contract rather than a courtesy.

Anything absent from this list is a second vendor you will eventually hire, plus the coordination cost of making two vendors share credit.

Guarantees: one red flag and one honest exception

The classic red flag reads: "We guarantee first-page rankings." Nobody controls Google, so anyone guaranteeing its behavior is either lying or planning to rank you for keywords so obscure that success is guaranteed and worthless in the same breath. The "don't pay until you rank" pitch is the same trick with better manners — it incentivizes the agency to chase the lowest-difficulty terms available, which are low-difficulty precisely because no client ever arrives through them. Of all the red flags in this market, guaranteed results is the oldest and the reddest; treat it as a disqualifier.

But the standard advice then concludes that no honest agency promises anything — which conveniently means agencies get to promise nothing and invoice anyway. The real distinction is between guaranteeing Google's behavior, which is impossible, and standing behind a measurable floor of your own performance, which any confident operator can do.

Ours, for the record: within 90 days, your campaign delivers at least one of the following — 20 percent growth in ranking keywords, 20 percent growth in Google Search Console clicks, or 20 percent more clients — or we keep working at no charge until we deliver. Read the structure, not the brand. It is a defined, measurable commitment with a deadline and a consequence we absorb; it promises no rankings and no specific outcome beyond that floor. Put the question to every law firm SEO company you interview: what floor do you stand behind, and what exactly happens when you miss it? Silence is also an answer.

Pricing models and the incentives inside them

How an agency charges tells you what it is optimizing for. Four pricing models dominate the market:

• Monthly retainer. The standard, and the right default — SEO is continuous work — provided the contract states what the monthly retainer buys. A retainer with vague deliverables is a subscription to hope.
• Hourly consulting. Fine for advisory work and audits; poor for execution, because it prices effort rather than outcomes and quietly rewards slowness.
• Project-based. Sensible for bounded work — an audit, a site migration, a penalty cleanup. As the ongoing model, it produces bursts of activity separated by silence, which is the opposite of how compounding channels work.
• Performance-based or pay-per-lead. Sounds like perfect alignment; usually isn't. It pushes the vendor toward shortcut tactics that produce fast, fragile wins on your domain, and it guarantees a definitional war over what counts as a "lead." The risk lands on your website; the upside lands on their invoice.

On price levels: quotes in this market appear to run from under $2,000 a month to well past $10,000, and a very cheap quote is a description of very cheap labor — usually the offshore content and rented links you will later pay to remove. We've published a full breakdown of law firm SEO pricing and an explanation of why SEO costs vary so much from firm to firm. For choosing purposes, one rule covers it: whatever the model, you should be able to see what ships each month and check it against the invoice.

Contracts: the paperwork is the honest part of the pitch

Everything in the sales deck is aspiration. The contract terms are the agency's actual opinion of the relationship, so read them the way you read the other side's draft.

Term length, checkpoints, and the way out

Six-to-twelve-month minimums are common and defensible — the work genuinely takes that long. A long-term contract with lock-in and no performance language is a different animal: revenue guaranteed to the agency whether or not anything happens for you. Negotiate performance checkpoints at 90 and 180 days with defined expectations at each, a cancellation policy in plain numbers (notice period, any early-exit fee), and a month-to-month agreement after the initial commitment. An agency confident in its work does not need a cage; it needs a runway.

Ownership of everything with your name on it

The most expensive clause in legal marketing is the hostage clause: the agency retains ownership of the website, the content, or both, often via a proprietary CMS that cannot be exported. Fire them and your web presence resets to zero. Before signing, get it in writing that the firm owns the domain, the website, all content created under the engagement, the Google Business Profile, the analytics properties, and any call-tracking numbers — on termination, without additional payment — and that domain registration and hosting sit in accounts you control. Treat website ownership, content ownership, and analytics access as the exit, negotiated at the entrance. An agency that registers your domain in its own name has taken a security deposit on your entire online identity.

Competitor exclusivity: are you funding the firm across the street?

Here is a question almost nobody asks: will the agency also work for your direct competitors? Many law firm SEO companies happily sign three PI firms in the same city — which means the strategy you pay for is being run, by the same people, against you. An agency serving multiple firms in one market is arbitrating which of its own clients wins. Ask the exclusivity policy outright, and if it is offered, define it in writing by practice area and geographic market. Expect it to be priced — genuine exclusivity costs the agency revenue, which is exactly why it means something. If the answer is "we keep client work separated internally," translate that as "no."

Bar compliance: the agency won't be the one disciplined

Every page, post, and ad an agency publishes for you is attorney advertising, and the disciplinary letter does not go to the vendor. The ABA Model Rules set the floor — Rule 7.1 prohibits false or misleading communications about a lawyer's services — and state bars layer their own legal advertising rules on top — restrictions on testimonials, specialization claims, results language, and required disclaimers that vary by jurisdiction. An agency writing "the best injury lawyer in the state" into your homepage is creating your ethics problem, not theirs.

Vet for it directly: does the agency know your state bar's advertising rules, and is there a review workflow you or your designated attorney signs off on before anything publishes? How does it handle superlatives, outcome claims, and guarantee language in your copy? The same conversation should cover white-hat SEO discipline generally — where links come from, whether content is mass-produced, what the agency thinks of tactics that risk Google penalties. An agency that hedges about its link sources is telling you the answer; it is just hoping you weren't listening.

The timeline test: 90 days, six months, twelve months

A realistic SEO timeline is itself a vetting tool, because the dishonest agencies are the ones promising speed. Page-one results in 30 days is either a miracle or a keyword nobody wants.

The first 90 days

Audit complete, technical fixes shipped, Google Business Profile rebuilt, keyword and competitive strategy documented, first content published, tracking configured. Rankings rarely move much this early — but the work should be fully visible even when results aren't. Judge activity now, outcomes later.

Six months

Target terms moving into the top 20, early map pack improvements, and the first inquiries you can attribute to organic search. If nothing has moved at all by month six, that is what the 180-day checkpoint in your contract is for.

Twelve months

Compounding: page-one presence on commercially valuable terms, a steady flow of qualified leads, and a cost per case you can put next to your pay-per-click numbers with a straight face. This is where the channel starts outrunning ads — and where the agency should be showing you the comparison unprompted.

The new question: what's their answer on AI search?

A growing share of legal research now appears to start in AI Overviews, ChatGPT, and their siblings rather than in ten blue links, and a client who asks an AI assistant "do I have a case?" may meet a law firm's content long before meeting the firm. That makes AI search visibility — generative engine optimization, GEO, answer-engine optimization, whatever label an agency prefers this quarter — a legitimate vetting criterion in 2026.

Listen for two kinds of answers. The good kind is measured and slightly boring: the agency tracks whether and where your firm is cited in AI-generated answers, and explains that earning those citations runs through fundamentals — clear entity signals, structured data, and authoritative content that a model treats as a source worth quoting. The bad kind comes in two flavors: the blank stare, and a proprietary "AI optimization package" that, on inspection, is the same deliverables renamed and surcharged. AI search is a real shift that mostly rewards the same rigorous work; an agency selling it as magic is telling you how it sells everything else.

Plan the exit before the entrance: the offboarding checklist

The single most revealing discovery-call question is "what happens when we leave?" — because a good agency has a boring answer and a bad one has a vague one. Confirm every item before you sign, and run it as a checklist when you eventually leave any agency:

• Written confirmation that the firm owns the domain, website, and all content on termination — no residual license, no buyout fee.
• A complete access inventory — CMS, hosting, DNS, Google Analytics, Search Console, Google Business Profile, call tracking — with the firm as owner or primary admin on every account.
• A full export of the website and content in a standard, portable format.
• Call-tracking numbers ported to an account you control, so years of the phone number printed on everything don't retire with the vendor.
• A record of links built and any disavow file submitted, so the next team inherits the history instead of guessing at it.
• A final handover report: work completed, work in progress, credentials transferred, and a reasonable transition window.
• Nothing in the contract permitting the agency to remove, repurpose, or resell work product after termination.
• Notice and cancellation terms you actually read before signing, back when everyone was still being charming.

Firms switching agencies should run this list against the current vendor before signing with the next one — the exit from the old engagement is part of the cost of the new one.

The discovery call script: every question to ask

Here is the whole article compressed into a script. Bring it to every discovery call, in order, and take notes on the answers — due diligence works better in writing.

• What percentage of your clients are law firms, and how many are in my practice area?
• Who will work on my account — names and roles — and how many other accounts does each of them carry?
• Is any of the work subcontracted, white-labeled, or performed offshore? Which parts?
• Who writes my content, what are their qualifications, and who reviews it for legal accuracy before it publishes under my name?
• Can I see two or three case studies from my practice area in comparable markets, with the firms named?
• Can I speak with two current clients who are not featured on your website?
• Can I see a sample keyword research deliverable, with volume, difficulty, and commercial intent?
• What did you find when you looked at my website, and how did it shape this proposal?
• Where, specifically, will my backlinks come from?
• What is in the monthly report? Can I see a real, redacted example?
• How will you track phone calls, form fills, and signed cases — and when is that set up?
• Who owns the website, content, Google Business Profile, analytics, and call-tracking numbers if we part ways?
• Do you work with my direct competitors, and will you put competitor exclusivity in writing — by practice area and market?
• What are the contract term, cancellation policy, and performance checkpoints at 90 and 180 days?
• What should I expect at 90 days, six months, and twelve months — and what happens if we get there and it hasn't?
• Do you guarantee anything? What is the measurable floor, and what do you do when you miss it?
• How do you keep my content compliant with my state bar's advertising rules?
• How do you measure and improve my visibility in AI search results?
• Walk me through your last offboarding. What did the client leave with?

Grade the manner as much as the matter. Plain language, specific answers, and visible comfort with the ownership and exit questions are the profile of an agency with nothing buried in the basement. Bristling at the script is itself a result.
