Here's the uncomfortable truth: most PI marketing directors set their own benchmarks. They compare this month to last month, this vendor to last quarter — without any external reference point for what “good” actually looks like. When a managing partner asks how your channels stack up, you need real numbers. Not aspirational targets from a vendor pitch deck, but performance ranges from firms running comparable budgets in competitive PI markets.
Bookmark this. It covers the benchmarks PI marketing directors need in 2026: daily lead pace, weekly signed case pace, contact rates, conversion rates, and cost per case by channel. Every number is a range, because single-point benchmarks are almost always misleading — and because where you fall within the range is often more actionable than the benchmark itself.
Daily Lead Pace Benchmarks
Daily lead pace is the first number most marketing directors check each morning — it tells you whether your lead generation engine is running at expected volume before you get into quality metrics.
Healthy pace depends on total monthly spend and number of active sources. As a general rule, expect 8 to 13 leads per business day per $100K in monthly spend:
- $150K/month spend: 12 to 20 leads per business day
- $300K/month spend: 24 to 39 leads per business day
- $500K/month spend: 40 to 65 leads per business day
If pace drops below the low end of your range for more than three consecutive business days, something changed — a vendor paused delivery, a campaign went offline, a market shift cut volume. Don't wait for the monthly report to investigate. The cost of a slow week compounds fast.
Weekly Signed Case Pace

Signed cases per week connects marketing activity to firm revenue. Lead volume is an input metric — signed cases are the output. You need both, but signed case pace is what partners actually care about at the end of the month.
$100K–$250K/mo
7–16
Signed cases per week
$250K–$500K/mo
15–33
Signed cases per week
$500K+/mo
25–60+
Signed cases per week
Lead pace on target but signed case pace below range? The gap is in your intake funnel — not your marketing. This is one of the most common misdiagnoses in PI marketing: blaming lead quality when the real problem is intake speed, contact rate, or follow-up process.
Contact Rate and Speed-to-Contact
Contact rate measures what percentage of inbound leads your intake team actually reaches by phone. It's the single most under-tracked metric in PI marketing — and it has an outsized impact on every downstream number in your funnel.
- Top-performing firms: 65–80% contact rate within 5 minutes of lead receipt
- Average firms: 45–60% contact rate within 15 minutes
- Below average: Under 40% contact rate, or average speed-to-contact over 30 minutes
Contact a lead within 5 minutes instead of 30 and conversion increases 3x to 5x. If your firm doesn't track speed-to-contact, it's one of the highest-ROI operational improvements available — and it costs nothing to measure.
Conversion Rate Benchmarks
Lead-to-signed-retainer conversion varies by source type, case criteria, and intake maturity. The ranges below cover general PI and auto accident matters — practice area and market will shift them, but the relative ordering holds:
| Below Average | Average | Top Quartile | |
|---|---|---|---|
| Google Ads (Exclusive) | Under 6% | 6–10% | 10–15% |
| Google LSA | Under 8% | 8–13% | 13–18% |
| Facebook / Meta Ads | Under 3% | 3–6% | 6–9% |
| Lead Aggregators (Shared) | Under 2% | 2–4% | 4–7% |
| TV / Broadcast | Under 4% | 4–7% | 7–10% |
| Referrals (Attorney + Client) | Under 20% | 20–35% | 35–50% |
| Organic / SEO | Under 10% | 10–18% | 18–25% |
Lead-to-signed-case conversion rates for general PI and auto accident matters.
The spread between below-average and top-quartile is stark. A firm converting Google Ads leads at 14% versus 6% cuts its cost per case by more than half — same ad spend, same leads. That gap is almost entirely explained by intake operations, not marketing quality. Which means the fix isn't more budget; it's faster follow-up.
Cost Per Case by Channel
Cost per case by channel is the benchmark managing partners actually understand — and the one that exposes which sources are working and which are quietly draining budget. It tells you what each signed case truly costs, after accounting for lead volume, lead cost, and conversion rate.
Ranges reflect 25th–75th percentile across PI firms spending $100K–$750K/month.
Channel-by-Channel Notes
- Referrals ($200–$800):Still the lowest cost per case channel for PI firms. The “cost” is largely relationship maintenance — attorney lunches, referral fee arrangements, and community presence. Firms that systematically invest in referral development consistently produce their best ROI here.
- Organic/SEO ($600–$2,200): High-value channel once established, but requires 6 to 12 months of sustained investment before producing meaningful case volume. The cost per case calculation should amortize content and SEO costs over the trailing 12 months.
- Google LSA ($1,200–$3,000): Strong performer for firms with good reviews and solid intake speed. LSA leads tend to be higher intent than standard search ads, which explains the better conversion rates.
- Google Ads ($1,800–$4,500): The workhorse of PI digital marketing. Wide cost per case range because campaign management quality varies enormously. Firms that optimize campaigns monthly tend to land in the lower half of this range.
- TV/Radio ($2,200–$5,500): High awareness channel that produces steady volume in established markets. Attribution is harder — many TV-driven leads arrive via branded search, which complicates cost per case tracking without proper attribution modeling.
- Facebook/Meta ($2,500–$6,000): Lower intent leads that require aggressive follow-up. Firms with strong nurture sequences and persistent intake teams get better results. Firms that treat Facebook leads like inbound calls struggle.
- Lead Aggregators ($3,000–$7,000): Shared leads are the most expensive on a cost per case basis because conversion rates are lowest. Exclusive lead programs from aggregators perform significantly better ($1,800–$4,000 range) but come at a higher cost per lead.
The Benchmark That Ties It All Together
Every metric above matters. But the one that anchors your reporting — and the one managing partners actually understand — is blended cost per case across your entire portfolio. For PI firms spending $100K to $750K/month, that benchmark is $1,500 to $4,500 per signed case.
If you're in that range, the next question is: where within it, and what would it take to move toward the lower quartile? Moving from $3,800 to $2,800 per case on a 100-case-per-month operation saves $100,000/month in equivalent marketing spend — or produces 36 more cases at the same budget. That's not optimization; that's a growth strategy.
