What’s A Reasonable SEO Budget For A Law Firm?

Every firm wants to know two things on the first call: what does this cost, and is it worth it. The first one is easier to answer than agencies make it sound. The second one depends almost entirely on whether the money is going to the right work — which most of the time, it isn’t.

I’m going to give you the real ranges, by firm size and by market. I’m going to tell you what each budget tier should reasonably produce. And then I’m going to make a claim that most of my industry would push back on: most law firms paying for SEO right now are paying too much for too little. Bigger budget isn’t always better. Sometimes it’s worse, because it gives the agency the financial cover to keep doing the wrong things at scale.

Legal SEO budget benchmarks by law firm size Four budget tiers by firm size. Firms under one million in revenue typically spend fifteen hundred to four thousand dollars per month. Firms between one and three million spend three thousand to eight thousand per month. Firms between three and ten million spend six thousand to fifteen thousand per month.

The honest ranges

Here’s what reasonable looks like, by firm size. These aren’t industry surveys — they’re what I see when I audit firms and look at their existing retainers, plus what we and the legitimate operators in this space charge.

Under $1M in annual revenue: $1,500–$4,000/month

This is the small-firm range. Solo practitioners, two-attorney shops, newer firms still building their case volume. At this size, the firm typically does not have a marketing manager — the owner is the marketing manager — and the entire SEO retainer needs to deliver work that’s defensible against the question “would I have signed this case anyway?”

What this budget should buy: a real audit at the start, focused work on three to five practice pages over the first six months, Google Business Profile management, citation cleanup, and a steady review-velocity program. Maybe one new page a month after the foundational work is done. Not 40 blog posts. Not “comprehensive content strategy.” A small number of high-leverage things done well.

If you’re a $700K firm paying $5,000 a month for SEO, you are almost certainly being upsold. The agency is using your retainer to make their account size goals work, not because $5K of work is actually being done on your firm. Push back. Get itemization. Or find someone who’ll scope it honestly.

$1M–$3M in annual revenue: $3,000–$8,000/month

This is where most of our clients land. The firm has enough revenue to invest seriously in growth, enough complexity to need real strategy, and usually multiple practice areas that each have their own SEO surface to think about.

What this budget should buy: a full practice-page audit and rewrite cadence (8 to 15 pages over the first six months), local SEO management across all office locations, ongoing review program, citation hygiene, schema implementation, and the start of a topical authority build with maybe one or two new long-form pieces per month after the foundation is solid.

At this tier, the work is enough to move the needle in a competitive market but not so much that the agency has to invent things to do. I would tell a firm in this revenue band that anything north of $8K a month is probably the agency padding the scope. There are exceptions — multi-location firms, particularly competitive markets — but the default expectation should be that this is the range.

$3M–$10M in annual revenue: $6,000–$15,000/month

Mid-market firms. Multiple attorneys, multiple practice areas, often multiple offices. Marketing leadership is in place. The firm is competing for high-value cases against other established firms, and the SEO surface is correspondingly larger.

What this budget should buy: everything from the smaller tier, plus depth — topical authority builds across multiple practice areas, sub-practice page expansion (e.g., “construction injury” as a child of “personal injury”), attorney bio optimization across the partner team, structured local SEO across each office, and a real measurement infrastructure (call tracking, CRM integration, attribution).

This is where I think most agency mills go off the rails. A firm in this band can be sold $15K a month of work easily, but a lot of it ends up being volume content that does nothing — because the agency has to justify the larger retainer. Discipline matters more here than at lower tiers. The most expensive SEO you can buy is high-volume bad work at a mid-market retainer.

$10M+ enterprise firms: $15,000+/month

Large firms. Often multi-state. The SEO surface is genuinely large — dozens of attorneys, multiple practice areas, multiple jurisdictions, sometimes hundreds of pages of existing content that needs ongoing maintenance.

At this size, a firm is often better served by a dedicated in-house SEO lead supported by an agency for specific projects, rather than turning the whole thing over to an agency that’s going to charge $25,000 a month and assign you a junior. More on that decision here.

I’ll be honest: I’m not usually the right answer at this tier. We’re a small consultancy. We can handle a mid-market firm comfortably. We are not going to scale to be a vendor of choice for a 60-attorney firm with offices in five states. If that’s you, an in-house lead plus a couple of specialist agencies — one for content, one for technical, one for local — is almost always the better operating model.

Why bigger budget often means worse outcomes

Here’s the part of this page that won’t sit well with the industry.

For most law firms in the $500K–$5M range, the marginal return on SEO spend flattens out somewhere around $6,000–$8,000 a month. After that, you’re not buying more results. You’re buying more activity. And more activity, in a discipline where most of what gets done doesn’t matter, just produces more of what doesn’t matter.

I’d rather charge a firm less and do less than charge them more and deliver theater. Theater is what most legal SEO retainers are buying right now.

Here’s how it goes wrong. A firm hears that “competitors are spending $12,000 a month.” They feel like they’re behind. They bump their budget to $10K with the assumption that more money equals more rankings. The agency now has to fill that budget. Their realistic capacity to do high-leverage strategic work for one firm is maybe $5K a month — beyond that, they have to invent activities. So you get 40 blog posts. You get a “content audit.” You get a “competitor analysis deck.” You get a guest post on a low-tier site. All of it is real labor. None of it is moving cases.

If you backed that same firm into a $5K budget, they would have gotten the high-leverage strategic work and nothing else. The result would have been better. The firm would have saved $60K a year. The agency would have been less happy.

This is why I think the question “how big a budget do I need?” is the wrong question. The right question is: “what is the smallest budget that buys the work my firm actually needs?” The answer is almost always less than the firm is currently spending or being pitched.

What each tier should actually produce

Budgets are abstractions. What you actually want to know is what the money buys in terms of outcomes. Rough expectations, by tier:

At $1,500–$4,000/month, expect the foundational work to get done over 6 to 9 months: practice page rewrites for your top three to five pages, GBP set up correctly, citations cleaned up, a working review program. Realistic outcome by month 12: meaningful ranking improvement on your most important local queries, measurable bump in inbound calls, a working foundation that doesn’t need constant maintenance.

At $3,000–$8,000/month, expect all of the above plus depth: 8–15 practice pages handled in the first half-year, multi-location local SEO if applicable, schema markup, the start of a content build, and proper measurement infrastructure. Realistic outcome by month 12: significantly improved rankings across multiple practice areas, a defensible attribution model showing what SEO is producing in cases.

At $6,000–$15,000/month, expect everything above plus ongoing sub-practice expansion, attorney bio depth, more aggressive topical authority, dedicated content production at a reasonable cadence (2–4 high-quality pages a month, not 40), and tight integration with the firm’s CRM and intake. Realistic outcome by month 12: SEO is the dominant source of new client acquisition for the firm, or a clearly identified second-place to referrals.

At $15K+/month, expect the work to be specialized — meaning multiple specialists touching different parts of the program, technical SEO depth, schema for complex multi-attribute pages, advanced local SEO across many locations, and dedicated content writers producing depth at scale. At this tier, the wrong setup ($15K to a generalist agency mill) is by far the worst dollar-for-dollar value in legal SEO. The right setup (in-house lead + specialist vendors) is the best.

In-house vs. agency: the cost comparison

A common question, especially at the mid-market tier: should I just hire someone in-house instead?

A competent in-house legal SEO hire costs somewhere between $75,000 and $130,000 in base salary, plus benefits, plus tools (Ahrefs/Semrush, CallRail, schema generators, project management software) which add another $5,000 to $15,000 annually. Loaded, you’re looking at roughly $100K to $170K all-in for a single full-time hire.

Compare that to a $5,000/month agency retainer ($60K/year) or even a $10,000/month retainer ($120K/year). On budget alone, an in-house hire can look comparable or even cheaper. The honest answer is more nuanced — an in-house hire usually can’t replicate the range of skills an agency provides (strategy, content, technical, local, link work, design support), so you typically end up needing both. Full breakdown of the trade-offs here.

For a $1M-$3M firm, in-house is rarely the right move — not enough leverage from a full-time hire. For a $3M-$10M firm, a hybrid model (in-house lead + a small specialist agency for strategy) tends to be the optimal cost structure. For a $10M+ firm, the in-house path becomes mandatory or you’ll spend a fortune on agency markup.

What you should NOT spend money on

At every tier, there are categories of spend that mostly don’t earn their cost. Some of these used to work better than they do now. Some never really worked.

Premium directory subscriptions you don’t actually use. Justia, FindLaw, Avvo, SuperLawyers, Best Lawyers — each one has its own pitch and its own price tag. Some are worth it for some firms in some markets. Most firms are paying for two or three they don’t need. Audit these annually.

Aggressive link-building campaigns. Outbound link-building for law firms is mostly buying placements on low-quality sites or trading favors for guest posts that nobody reads. The risk-reward is bad. Legitimate links — earned through original research, press, or genuine partnerships — are valuable. Paid link campaigns at $2K-$5K/month are almost always a waste at best and a penalty risk at worst.

High-volume blog content. Forty blog posts a month, AI-generated or thinly written by junior writers offshore, do not rank, do not produce cases, and dilute the topical signal of the rest of your site. This is one of the largest line items in many retainers and one of the least defensible.

“Brand awareness” SEO add-ons. If an agency proposes a layer of work for “brand visibility” that isn’t tied to either rankings or calls, ask what specifically it produces. The answer is usually a chart of impressions going up.

Layered tools the agency uses on your behalf. Some firms get charged for “platform access” or “reporting dashboards” on top of the retainer. This should be included. If it’s a line item, that’s the agency’s tools being passed through to you as a markup.

Our approach to pricing

I’ll be specific about what we do, since this page is about budget benchmarks. Most of our engagements land between $3,000 and $9,000 a month. We scope based on the firm’s existing surface — number of practice pages that need work, number of office locations, market competitiveness, current review profile — and we tell the firm what the work is and what it costs before we start.

If a firm walks in wanting to spend $15,000 a month, I will usually quote them less, because the right work for their situation doesn’t add up to $15K. I would rather take less of their money and do the work that actually moves their case volume than expand the scope to fill the budget. More on how we charge here.

The other thing I’d say is that pricing in this industry is usually quoted to maximize lifetime contract value, which is why you see lots of $5K-$8K retainers on 12-month lockups. If a vendor’s pricing only makes sense across 12 months of guaranteed retention, that’s the contract speaking, not the work. We charge month-to-month for the same reason — the retainer reflects the work in that month, not the work in some imagined year-long arc.

How to decide what to budget

If you’re trying to set or reset your SEO budget, here’s the framework I’d use:

  1. Start with the work, not the dollar amount. What does your firm actually need fixed? Audit the practice pages, the GBP, the citations, the reviews, the technical site. Make a list. Then ask what it would cost to do that list well. That’s your budget floor.
  2. Compare it to what one case is worth. If your average signed case is worth $5,000 in revenue and the SEO work needs to produce three new cases a year to break even at $1,250/month, the math is different than if you’re an estate planning firm where the average matter is $3,000. PI firms can justify higher budgets faster than family or estate firms because case value is higher.
  3. Plan in quarters, not years. Don’t commit to 12 months of spend up front. Plan three months of spend, evaluate, plan the next three. This forces you to actually look at what’s working instead of paying on autopilot.
  4. Build measurement first. If you can’t track whether the SEO work is producing calls and signed cases, you can’t budget intelligently. Call tracking and form attribution are tier-one infrastructure — if your agency hasn’t set these up, that’s the first thing to fix. More on measurement here.
  5. Walk away from budget pressure that doesn’t tie to work. “We recommend $10K a month for firms in your market” is a pitch, not a scope. Ask what specific work that $10K buys and whether you actually need it.

A final word on “reasonable”

What’s reasonable depends on what’s needed. A $1.5M firm in a low-competition market with a clean foundation might do beautifully on $2,500 a month. A $4M firm in Phoenix PI fighting for visibility against 20 well-funded competitors might genuinely need $9K. There is no universal right answer — but there are wrong ones, and the most common wrong answer is “more than I needed to spend.”

If you want to know what your firm specifically should be budgeting, the free audit will tell you. I’ll look at what’s in front of me, scope what the right work is, and quote what it would cost. Sometimes the answer is “less than what you’re paying now.” Sometimes it’s “you’re under-investing and your competitors are eating your lunch.” Either way, you’ll know the number before you commit to anything.
