How Much Should Law Firms Spend on Marketing to Get a Solid ROI?

When law firms consider their marketing budget, the key questions are always: How much should we spend to ensure a solid return on investment (ROI)? How should we invest strategically for a strong, measurable return? The answer isn’t one-size-fits-all—it depends on your firm’s growth goals, competitive landscape, and practice area.

Under-investing can lead to stagnation, while overspending in the wrong areas can be wasteful.

With the right strategy and expert guidance from Neon Ambition, though, you can strike the perfect balance for sustainable growth.

Here are a few things to keep in mind while establishing your marketing budget:

Your Budget Should Match Your Growth Goals

Before setting your marketing budget, it’s essential to clearly define what success looks like for your firm. Are you looking for aggressive growth, or are you aiming to maintain your current caseload while increasing the quality of leads? At Neon Ambition, we help law firms clarify these goals and translate them into actionable marketing strategies that align with both short-term and long-term objectives.

  • Firms or those looking for aggressive growth should expect to invest more in both pay-per-click (PPC) advertising and search engine optimization (SEO) to drive more leads and cases.
  • Firms that are at capacity and not looking to scale significantly can maintain a lower investment and focus more on CRO, SEO, reputation management and brand presence rather than aggressive lead generation.

A common benchmark is that law firms should allocate 7-10% of their gross revenue to marketing, but firms in highly competitive markets (e.g., personal injury) often need to spend 15% to 20% or more to dominate their local market.

Newer Firms Need to Spend More to Establish Themselves

If your firm is new, building trust and visibility takes more than a website and hope. This is what caused me to start the online marketing division at the web design agency I worked for in Sydney. Now at Neon Ambition, we help newer firms accelerate their presence through expertly managed PPC campaigns that deliver immediate visibility. Meanwhile, we build the foundation for long-term success with targeted SEO, strategic content marketing, and reputation management.

We also help clients leverage simple, low-cost tactics — like monthly client newsletters and automated review requests — to generate referrals and build social proof. For established firms, we help maintain momentum and protect your market share with ongoing SEO and brand management strategies that keep your firm top-of-mind.

If you’re a new law firm without much online history, expect to invest more upfront to establish credibility and rankings.

  • PPC can provide quick wins to get immediate visibility.
  • SEO will take time but is necessary to build sustainable growth and often has the best long-term return on investment.
  • Content marketing, reviews, and backlinks are crucial to gaining trust. Simply emailing your past clients once a month and on their birthdays is a good low-cost way to drive reviews and referrals.

PPC and SEO Work Differently—You Need to Balance Short- and Long-Term Strategies

Law firms should invest in both PPC (Google Ads, Local Service Ads) and SEO, but in the right proportions depending on their needs:

  • PPC (Google Ads & LSAs): This provides immediate traffic and leads but requires a steady, ongoing investment. The cost per click for competitive personal injury keywords can be $50–$200+, making PPC a high-stakes but high-reward channel. After all, we aren’t selling t-shirts online. The reason these clicks are so costly is because the potential return is so high in personal injury.
  • SEO (Search Engine Optimization): While PPC brings fast results, SEO is the foundation for sustainable growth. It’s a long-term strategy that builds organic rankings and credibility over time. Google recommends 4-12 months to start seeing significant results, depending on competition and where you are starting from but with consistent effort and expert strategy, you can see momentum sooner..

Many firms find success in allocating 60-70% of their marketing budget to PPC for immediate leads while investing the rest in SEO and content marketing for long-term growth. Some firms choose to only invest in SEO for long-term growth. There is no one-size fits all recommendation here as your own circumstances and goals should dictate what mix is right for your firm. SEO typically has the best long term ROI but can take time to achieve this.

Your Investment in Legal Marketing Depends on Practice Area & Market

Some practice areas are significantly more competitive than others. For example:

  • Personal Injury (PI) and Mass Torts: Among the most expensive practice areas for marketing, often requiring budgets of $20,000–$100,000+ per month in major markets.
  • Criminal Defense, Family Law, and Immigration: Less competitive than PI, but still requiring $4,000–$20,000 per month to be competitive.
  • Estate Planning and Business Law: Typically require $2,500–$10,000 per month, as they have lower competition and more referral-driven business.

Market Size Matters

Additionally, firms in major metro areas (e.g., Los Angeles, New York, Chicago) will need a significantly larger budget than those in smaller cities or rural markets due to the increased cost per click and higher competition. This increased investment is offset with increased opportunity! We help law firms navigate these high-stakes markets by tracking every marketing dollar, making data-driven adjustments, and ensuring that each campaign delivers measurable, meaningful results.

Final Thoughts: Let Neon Ambition Help You Align Your Budget with Your Expectations

The most successful law firms align their marketing budgets with clear, measurable goals — and partner with agencies that hold themselves accountable to those goals. Under-investing leads to stalled growth; overspending without strategy leads to waste. At Neon Ambition, we guide firms to the right balance of ambition and discipline, ensuring every dollar is tracked and optimized.

A well-planned budget should:

  • Align with growth goals (aggressive growth vs. maintaining caseload).
  • Balance short-term PPC with long-term SEO.
  • Consider practice area and market competition.
  • Account for higher initial investments for new firms.
