Google Ads for Law Firms: Budget, Bidding, and ROI Guide (2026)

By IronFlow Advertising · September 26, 2026 · 3 min read

Short answer

Set your Google Ads budget by working backward from target signed cases, your sign rate and realistic cost per click in your market. Start with tightly focused keywords and locations, track calls and forms through to signed cases, feed outcomes back to Google, and move to automated bidding only once you have enough conversion data.

Budget math

Clicks needed = target cases / (click-to-lead rate x lead-to-case rate).
Budget = clicks needed x expected cost per click.

PI clicks in competitive markets can be expensive, so small budgets spread across too many keywords rarely produce enough data.

Keyword strategy

Focus on high-intent terms with location modifiers.
Separate MVA, truck, workers’ comp and other case types into their own campaigns.
Build a strong negative keyword list (jobs, schools, free, DIY forms).

Bidding

Start with manual or maximize-conversions bidding with tight controls.
Move to target cost-per-acquisition bidding once you have steady conversion data.
Import signed cases as offline conversions so Google optimizes toward cases.

Landing pages

One page per case type and location, fast on mobile, with click-to-call and a short form.
