How to Tell If Your Law Firm's Marketing Is Actually Working

Marketing that "feels busy" is not the same as marketing that works. Clicks, impressions and even lead volume can all rise while the number that matters — signed cases — stays flat. To know whether your spend is producing clients, you have to follow the money all the way to a signed retainer.

Measure to the signed case, not the click

The single most important metric is cost per signed case: total marketing cost divided by the cases that produced a signed retainer, measured across your real sales cycle. Everything upstream — cost per click, cost per lead — only matters if it produces retained clients at a cost your firm can sustain.

Watch the whole funnel, not just the top

• →Spend by channel and practice area
• →Leads and qualified leads (real conversations, not hang-ups)
• →Consultations booked and consult-to-retained rate
• →Signed cases attributed back to source, campaign and keyword
• →Cost per signed case by channel

Respond fast — the data says most firms don't

Speed to a new lead is one of the biggest hidden leaks. According to Clio's 2024 Legal Trends Report, 67% of law firms fail to respond to a prospective client's email and 48% are effectively unreachable by phone. If your marketing is generating leads that intake never reaches, the problem may not be the marketing at all — and only reconciling marketing against intake will tell you which it is.

Review weekly, decide with evidence

Firms that reallocate budget weekly — based on search terms, negative keywords and funnel metrics — compound results over time. If you can't answer "which keywords produced signed cases?", your measurement is incomplete, and any vendor comparison is guesswork.
