Silver Atlas finds most law firm marketing case studies stop at leads

A Silver Atlas review of 50 public law firm marketing case studies found only 3 disclosed cost per signed case, highlighting a gap between lead-generation claims and client-acquisition results. The analysis suggests many published examples still lack the data firms need to compare marketing performance on a case-level basis.

Why it matters: - Law firms evaluating marketing providers often see lead counts, calls and consultations instead of signed-case results. - That makes it harder to compare campaigns on the metric that matters most: retained work and revenue per acquired client. - The gap can also obscure whether a campaign that looks efficient at the lead stage actually produces profitable cases.

What happened: - Silver Atlas reviewed 50 public law firm marketing case studies from 11 marketing providers. - The review found that only 3 case studies, or 6%, disclosed cost per signed case. - The sample covered published claims tied to SEO, Google Ads, Local Services Ads, social media and mixed digital campaigns. - The case studies were publicly accessible on 7 August 2026 and had to include at least one quantified marketing or commercial outcome to qualify.

The details: - Of the 50 case studies, 30, or 60%, quantified enquiries, leads or consultations. - Ten, or 20%, quantified signed cases or clients. - Five, or 10%, reported cost per lead. - Three reported cost per signed case. - Half of the sample reported either a numeric signed-case outcome, revenue or return on investment. - The other half stopped at earlier stages such as traffic, rankings, engagement, calls or leads. - Sixteen entries reported revenue or return on investment, but only 1 also quantified signed cases or clients. - Only 1 of the 50 entries stated criteria for classifying a lead as qualified. - Thirty-five, or 70%, provided a numeric campaign duration or dated comparison period. - The full report includes the methodology, limitations and a source appendix listing all 50 case studies and their coding.

Between the lines: - The review does not prove providers failed to track signed cases internally. - It shows only what those providers chose to disclose in public case studies. - Silver Atlas did not independently audit advertising accounts, intake records or financial data. - Revenue figures without case volume limit the ability to calculate revenue per acquired client from the published material. - The shortage of qualified-lead definitions also makes cross-provider comparisons less reliable.

What's next: - Silver Atlas says the report is intended to help law firms assess marketing using commercial outcomes, not just lead-generation metrics. - The research adds pressure on agencies to publish signed-case counts, spend, time period and attribution method alongside performance claims. - Firms that want clearer comparisons may increasingly demand case-level reporting before hiring a marketing vendor.

The bottom line: - Public law firm marketing case studies still favor top-of-funnel metrics. - Signed-case disclosure remains rare, even though it is the clearest way to measure whether marketing actually produces clients.
