Why PI is the hardest measurement problem in legal marketing
The highest CPCs in the vertical (retail bids above $90 in Google Ads Keyword Planner auction data), a conversion path that runs almost entirely through a phone call, a channel mix that typically spans TV or radio, paid digital, and referral or co-counsel networks simultaneously, and case values that can vary by an order of magnitude or more within the same practice area.
The channel mix problem
Digital campaigns often get credit for calls actually driven by TV or radio brand recall, or the reverse - a prospect sees a billboard, searches the firm's name, and clicks a paid brand-term ad that had nothing to do with the original awareness. Dedicated tracking numbers per channel, not per campaign, are the baseline fix.
Case value, not just case count
A cost-per-signed-case number that ignores case value can push budget toward high-volume, low-value case types purely because they are easier to close. Where the firm's intake system supports it, cost per case should be tracked by injury type or practice sub-area, not blended into one average.
Lane: We are measurement engineers, not a marketing agency - Webclat does not sell SEO, PPC, or marketing services. What follows is what to verify about the SEO/PPC/marketing spend a firm already buys, from us or from anyone else.
Channel, blind spot, fix
| Channel | Typical measurement blind spot | What closes it |
|---|---|---|
| TV / radio | No click event, so digital gets uncredited call volume | Dedicated, call-only tracking numbers per channel |
| Paid search | Broad geographic or practice-area bleed | Geo-fencing, negative keywords, and call disposition |
| Referral / co-counsel networks | Referral calls miscoded as organic or direct | Source-tagged intake fields for referral origin |
| Mass tort intake vendors | Lead cost hides wide case-quality variance | Disposition-to-signed rate by vendor, not lead cost alone |
Illustrative: a firm's TV spend might appear to underperform digital in a raw call count, until call attribution corrects for brand-recall-driven calls landing on a paid search line instead - illustrative scenario, not a measured result.
