A law firm gets leads from paid ads (Google, Local Services Ads, Meta, ChatGPT), organic discovery (SEO, Maps, AI assistants), referrals and purchased leads. No channel wins everywhere: urgent case types lean on Google and Local Services Ads, while questions asked in plain language increasingly start in ChatGPT. Judge every channel on cost per signed case and speed of response, not on lead volume.
The channels side by side
| Channel | Who it reaches | Speed | Control | Notes |
|---|---|---|---|---|
| Google Search Ads | People searching now | Fast | High | Auction priced; see Google Ads for law firms |
| Google Local Services Ads | Local searchers, Google Verified badge | Fast | Medium | Pay per lead, not per click |
| Meta (Facebook, Instagram) | People not searching yet; retargeting | Fast | High | Better for awareness and retargeting than urgent intent |
| ChatGPT Ads | People asking an AI who to call | Fast after approval | High | $25/day minimum; US legal ads only if licensed where shown |
| SEO and Maps | Searchers, over time | Slow | Medium | Compounds; see law firm SEO |
| AI visibility (GEO) | People asking ChatGPT, Gemini, Perplexity | Slow | Lower | Earned mentions; no guarantee |
| Referrals | Past clients, other lawyers | Steady | Low | Does not scale on demand |
| Purchased leads | Vendor-generated | Fast | Low | Often shared; see buy, rent or earn |
Which channel for which case type
- Urgent, high-intent cases (accidents, DUI, arrests): Google Search Ads and Local Services Ads first, because people search the moment it happens.
- Cases asked as questions (who pays, what are my rights): ChatGPT Ads and AI visibility add reach where people ask instead of search.
- Cases with a long decision (estate planning, immigration, family): SEO, content, reviews and retargeting.
- Mass torts: compliance-heavy; see mass tort marketing.
Practice-area pages: personal injury, criminal defense, family law, immigration.
The metrics that matter
- Cost per lead (a diagnostic, not a goal)
- Lead-to-consult rate
- Consult-to-signed rate
- Cost per signed case
- Average case value by source
- Speed to first response: the firm that answers first often signs the case
Track every lead to a signed case in one sheet or CRM from day one. Without it you will optimize the wrong channel.
How to test channels without wasting budget
- Choose one case type and one city.
- Run one new channel at a time with a fixed test budget.
- Keep intake the same, so the channel is what changes.
- Review at 30 and 60 days on cost per signed case.
- Scale what signs, cut what does not.
For ChatGPT Ads, a campaign can start at $25 a day; see how to advertise on ChatGPT as a lawyer. To compare paid options, read ChatGPT Ads vs Google Ads.
Where leads leak
Most firms lose signed cases after the lead arrives: slow callbacks, no after-hours coverage, no follow-up sequence, and no tracking. Fix intake before adding spend.
Who can run it
Bookedly (bookedly.co) is an AI marketing agency for law firms that runs ChatGPT Ads, AI SEO, Google and Meta ads, one firm per case type per city, month-to-month.
