Evaluation Guide
How to Evaluate a Marketing Agency for Your Personal Injury Firm
Most PI firms spend $10,000–$50,000 per month on agency fees and cannot independently verify whether that spend is producing results. The agency controls the data, writes the reports, and grades their own homework. This guide gives you the framework to evaluate agency performance with data — not promises.
The Core Problem
Why PI Marketing Agencies Are Hard to Evaluate
Marketing agencies have an inherent conflict of interest: they are reporting on their own performance. The data they show you comes from platforms they manage, filtered through dashboards they built, presented in reports they designed. This does not make every agency dishonest — but it means you are relying on the vendor to tell you whether the vendor is doing a good job.
Personal injury adds complexity that most industries do not have. The 6–18 month gap between a lead arriving and a case settlingmeans true ROI data takes months to materialize. Agencies report what they can measure quickly — leads, clicks, impressions — because the metrics that actually matter (cost per signed case, cost per settlement dollar) require patience, attribution, and data the agency often does not have access to.
The result: most PI firms evaluate their agency on the metrics the agency chooses to report, not the metrics that determine whether marketing spend is profitable. And the metrics agencies prefer to report — cost per lead, total leads, website traffic — can look good while cost per case quietly climbs.
The Conflict of Interest
Agencies report on their own performance. Self-graded scorecards rarely reveal underperformance.
The PI Time Lag
Settlement cycles of 6–18 months mean true ROI data arrives long after the money is spent.
The Metrics Gap
Agencies report what is easy to measure (clicks, leads) not what matters (cost per signed case).
Evaluation Framework
The 7 Criteria for Evaluating a PI Marketing Agency
Use these seven criteria whether you are evaluating a new agency or auditing your current one. Each criterion maps to a specific capability you can verify.
Do they report cost per case, not just cost per lead?
Cost per lead is an input metric. It tells you what you paid for an inquiry, not what you paid for a signed client. An agency that only reports CPL is giving you half the picture. The agency should be able to tell you, by channel, what each signed case cost to acquire.
Do they provide transparent, source-level spend data?
You should see exactly how every dollar is allocated: ad platform spend, vendor fees, management fees, creative costs. If the agency bundles everything into a single line item, you cannot evaluate which channels are performing and which are burning budget.
Can they show intake conversion rates by channel?
Leads are not equal. A channel that produces 200 leads with a 2% sign rate is not outperforming a channel with 40 leads at a 20% sign rate. Your agency should track and report conversion from lead to consultation to signed case, broken out by source.
Do they have PI-specific experience (not just “legal marketing”)?
Personal injury marketing is fundamentally different from estate planning, family law, or criminal defense. The settlement lag, the contingency fee model, the lead vendor ecosystem, the intake complexity — a generalist legal agency will miss the nuances that drive cost per case.
Will they connect to your independent tracking system?
An agency that resists independent performance verification is telling you something. A confident agency welcomes third-party tracking because it validates their work. If they push back on connecting to your CRM or attribution platform, ask why.
Do they set measurable performance targets upfront?
Before any money changes hands, the agency should define specific targets: cost per case by channel, lead volume, intake conversion rates. Vague promises like “increase your online presence” or “grow your brand” are not measurable and cannot be evaluated.
Can they explain their strategy for your specific market and case types?
A good agency tailors strategy to your geography, case mix, competitive landscape, and firm capacity. If the pitch deck they show you looks identical to what they showed the last PI firm, they are selling a template, not a strategy.
Warning Signs
Red Flags That Signal an Underperforming Agency
Any one of these should prompt a serious conversation. Two or more should trigger a formal review with defined timelines for improvement.
They only report vanity metrics (impressions, clicks, CPL)
Impressions and clicks measure visibility, not results. If your monthly report leads with website traffic and click-through rates but never mentions signed cases or cost per case, the agency is reporting activity, not outcomes.
They resist independent performance tracking
An agency that discourages you from tracking results independently has a reason. Confident agencies welcome external validation. Resistance to independent attribution — whether through your CRM, a platform like RevenueScale, or your own spreadsheets — is a serious warning sign.
They can't tell you cost per signed case by channel
If your agency cannot produce a report showing cost per signed case broken out by Google Ads, LSAs, Facebook, each lead vendor, and organic — they either lack the tracking infrastructure or do not want you to see the numbers.
They lock you into long contracts without performance clauses
A 12-month contract with no performance benchmarks and no exit clauses protects the agency, not you. Look for agreements that include quarterly performance reviews against defined targets, with clear remediation timelines and exit provisions if targets are missed.
They use the same strategy for every PI firm regardless of market
A firm in Atlanta competing against Morgan & Morgan needs a different strategy than a firm in Boise with two competitors. Cookie-cutter approaches — identical ad copy, identical landing pages, identical channel mix — signal an agency that scales through templates, not expertise.
They blame “the market” when performance declines
Markets do shift, but a competent agency anticipates and adapts. If declining performance is always attributed to external factors — seasonality, competition, algorithm changes — without a concrete recovery plan and timeline, the agency has stopped earning their fee.

What Good Agency Reporting Looks Like vs. What Most Firms Get
What Agencies Typically Report
These metrics measure activity. They tell you what the agency did, not what it produced. You can have growing traffic and declining signed cases at the same time.
What You Actually Need
These metrics measure outcomes. They tell you what your spend produced and where your next dollar should go.
The litmus test
Ask your agency: “What was our cost per signed case from Google Ads last month?” If they cannot answer immediately with a specific number, their reporting infrastructure is not built around the metrics that matter to your firm.
Accountability Framework
How to Hold Your Agency Accountable With Data
Accountability is not adversarial. The best agency relationships are built on shared data and clear expectations. Here is how to structure yours.
Establish a monthly review cadence
Schedule a standing monthly call with your agency. Review the same metrics every month in the same format. Consistency makes trends visible. If the agency resists a regular cadence, they are avoiding accountability.
Track the metrics that matter independently
Do not rely solely on your agency's reports. Pull your own data from your CRM, intake system, or a platform like RevenueScale. When you have independent numbers, the conversation shifts from “trust us” to “let's compare data.”
Use data to structure performance conversations
Replace “it feels like leads are down” with “cost per signed case from Google Ads rose from $2,800 to $4,200 over the past three months — what is driving this?” Specific data forces specific answers.
Define what “success” looks like in advance
Before each quarter, agree on specific targets: cost per case by channel, lead volume minimums, intake conversion benchmarks. At the end of the quarter, compare results to targets. No ambiguity, no interpretation debates.
This makes good agencies better
Data-driven accountability does not punish good agencies — it validates them. When an agency can point to independently verified cost per case data showing their performance, it strengthens the relationship and justifies their fees. The agencies that resist this are the ones you should worry about.
Decision Framework
When to Keep vs. Fire Your Marketing Agency
The decision to keep or replace an agency should be based on data, not frustration. Use this framework to make the call objectively.
Signals to Keep
Signals to Replace
The 90-Day Improvement Window
Before terminating an agency relationship, give them a formal 90-day improvement period with specific, measurable targets. Share the data that prompted the review. Define exactly what “improvement” looks like — a specific cost per case target, a conversion rate improvement, a reporting standard. If they hit the targets, the relationship continues. If they do not, you have documented cause to exit and clear data to evaluate the next agency against.
The cost of inaction
Every month you spend with an underperforming agency is a month of marketing budget producing suboptimal results. At $30,000/month in agency spend, waiting six months to make a change is $180,000 that could have been allocated more effectively. Data makes the decision faster.
Build vs. Buy
Agency vs. In-House Marketing: How PI Firms Should Decide
The decision is not just about cost — it is about control, expertise, and accountability. Most PI firms at $100K–$750K/month in ad spend benefit from agency execution combined with independent tracking infrastructure.
| In-House Team | Marketing Agency | Agency + RevenueScale | |
|---|---|---|---|
| Monthly cost | $8K–$15K (salary + benefits) | $5K–$25K retainer | $5K–$25K retainer + platform fee |
| PI-specific expertise | Varies — depends on hire | Varies — must vet carefully | Varies — data layer fills gaps |
| Speed to launch | 60–90 day ramp | 2–4 weeks | 2–4 weeks |
| Budget control | Full control | Shared control | Full visibility + control |
| Independent performance data | |||
| Cost per case by channel | Manual — spreadsheet dependent | Rarely provided | Automated, real-time |
| Scales with ad spend | Limited — headcount bottleneck | Yes — agency absorbs volume | Yes — scales automatically |
| Accountability mechanism | Internal review only | Self-reported metrics | Independent third-party data |
Based on typical PI firms spending $100K–$500K/month in total marketing. Costs exclude ad spend.
The most common mistake PI firms make is treating this as a binary choice. In-house marketers excel at brand consistency and institutional knowledge. Agencies bring channel-specific expertise and execution capacity. The gap both models share is independent attribution data — neither an in-house team nor an agency has a structural incentive to report underperformance.
Firms spending $200K or more per month on marketing almost universally benefit from a hybrid model: agency execution paired with a platform that tracks cost per case by channel from lead to signed case, independent of both the agency and the in-house team.
Industry Benchmarks
What PI Firms Actually Pay — Retainers, Fees, and Cost Per Case by Agency Type
Most agencies are reluctant to publish pricing. These ranges come from conversations with PI marketing directors across the country and reflect 2025–2026 market rates.
Boutique PI-Specialist Agency
$5K–$12K
Per month. Typically 2–5 PI clients. Deep PI expertise but limited channel breadth.
Mid-Size Legal Marketing Agency
$8K–$20K
Per month. Handles PI + other practice areas. Broader channel capability.
Large Multi-Practice Agency
$15K–$40K
Per month. Full-service (PPC, SEO, content, social). May lack PI depth.
Paid Search (Google Ads)
$800–$2,500
High intent, fastest to scale. Cost rises sharply in competitive markets.
Local Services Ads
$600–$1,800
Best cost per case when actively managed. Degrades without bid management.
Paid Social (Facebook/Meta)
$1,200–$4,000
Higher volume but lower sign rates require strong intake to convert.
Organic SEO
$200–$600
Lowest long-term cost per case. 12–18 month ramp. Compounds over time.
Ranges reflect mid-size markets (not LA, NY, or Houston, which run 2–3× higher). These are signed case costs, not lead costs.
Why benchmarks matter for agency negotiations
When you know that signed case costs from Google Ads should fall between $800 and $2,500 in your market, you can evaluate your agency against a real standard instead of accepting whatever they report. If your agency is delivering Google Ads cases at $4,500 with no improvement trend, you now have data to anchor the conversation.

Channel Evaluation Guide
What to Evaluate by Channel: PPC, LSA, SEO, Social, and Content
Different channels require different expertise. An agency that excels at paid search may be mediocre at SEO or content. Evaluate channel capabilities independently — and make sure whoever manages each channel can articulate performance in terms of cost per signed case, not channel-specific vanity metrics.
Paid Search (PPC / Google Ads)
What to Evaluate
- Keyword strategy for high-intent PI terms ("car accident attorney [city]", "personal injury lawyer near me")
- Negative keyword lists — PI PPC bleeds budget without aggressive negatives
- Landing page conversion rates, not just click-through rates
- Campaign structure: separate campaigns by case type, not one catchall
Benchmark
Cost per click for PI terms: $8–$45 in mid-size markets, $45–$200+ in competitive markets (Los Angeles, New York, Houston)
Watch For
Agencies that optimize for impressions or Quality Score instead of cost per signed case
Local Services Ads (LSAs / Google Screened)
What to Evaluate
- Bid management strategy — LSA pricing fluctuates and requires active management
- Profile optimization: reviews, license verification, photo quality
- Lead dispute process — invalid leads must be disputed immediately
- Integration with CRM to close the attribution loop
Benchmark
LSA cost per lead for PI: $80–$400 depending on market competitiveness and case type
Watch For
Agencies that set LSA budgets and let them run without active bid and review management
SEO & Content
What to Evaluate
- Local SEO strategy: Google Business Profile, NAP consistency, local citations
- Content production cadence and topic authority plan
- Technical SEO: site speed, Core Web Vitals, schema markup (LocalBusiness, Article, FAQ)
- Link acquisition strategy — PI is highly competitive for organic rankings
Benchmark
Organic leads typically have the lowest cost per case but the longest ramp time (6–18 months to see meaningful volume)
Watch For
Agencies that promise page-one rankings in 90 days or rely on thin, AI-generated content
Social Media Advertising
What to Evaluate
- Audience targeting strategy — geography, intent signals, lookalike audiences
- Creative testing cadence: how frequently are new ad concepts tested?
- Lead form vs. landing page strategy and conversion rate optimization
- Integration with CRM to track from social lead to signed case
Benchmark
Social leads for PI generally have higher volume but lower sign rates (2–8%) vs. paid search (10–20%)
Watch For
Vanity metrics (video views, likes, shares) presented as performance indicators
Content Marketing
What to Evaluate
- Topic authority strategy: does content cluster around practice areas or scatter broadly?
- Author expertise and E-E-A-T compliance — attorney authorship or review
- Distribution plan beyond just publishing — outreach, email, social amplification
- Conversion path from informational content to consultation request
Benchmark
Content-driven organic leads take 12–24 months to ramp but compound over time with zero incremental cost per lead once ranked
Watch For
Content farms producing 500-word posts on broad topics with no PI-specific depth or attorney involvement
The critical insight across all channels: every channel should be evaluated on cost per signed case, not on channel-specific performance indicators. An agency that insists on reporting LSA performance in cost per lead and paid search in cost per click is structuring reporting to obscure cross-channel comparison. Demand a unified cost per signed case view across all channels every month.
If you are using multiple agencies — one for paid search, another for SEO — assign clear attribution rules before either agency begins. Without a shared attribution framework, every channel will take credit for every case and no channel will own a number.
