The short answer
Law firm clicks are among the most expensive in search ads, so firms worry about competitors, bots and accidental clicks. Google filters most invalid clicks before billing and credits some found later, and a firm can ask for a review of recent activity. The best defense is measuring signed clients by source, keeping ads off low-quality placements, and checking the invalid-clicks report.
A personal injury firm pays more for a single click than many businesses pay for a day of ads, so a sudden jump in clicks with no new calls feels like theft. Sometimes it is invalid traffic. More often it is a targeting or measurement problem. This guide explains what Google already does about invalid clicks, the signs worth checking, and the settings that cut waste.
What counts as an invalid click?
Google’s definition: Invalid clicks are clicks on your ads that don’t represent a genuine interest in your business. That covers bots and automated tools, accidental clicks from poorly placed ads, and repeated clicks meant to raise your costs. A click from a real person who turns out not to be a fit, such as a job seeker, is not invalid; it is a targeting problem.
What does Google do about invalid clicks?
Google filters most invalid clicks out of your metrics and your bill before you are charged, and shows them in an “Invalid clicks” column. For the ones found later, If Google detects invalid clicks after you were previously billed for them, you receive a credit on your next invoice where appropriate and possible. If you suspect activity the filters missed, you can submit an invalid traffic investigation request for activity within the last 60 days.
What signs should a firm check?
Check these signs before calling it fraud. Each points to a cause and a fix; the conclusion of the table is that most problems a firm sees are waste it can fix with settings, not fraud.
| Sign | Likely cause | What to do |
|---|---|---|
| Clicks rise, calls and forms don’t | Ads showing on search partners or display placements, or broad keywords | Review where the clicks came from; tighten networks and match types |
| Many clicks from one area outside your service area | Location set to “interest in” rather than “presence in” | Target people located in your area |
| Bursts of clicks at odd hours with very short visits | Bots or automated traffic | Check the invalid-clicks column; request an investigation if needed |
| Calls from job seekers or people needing another practice | Keywords that match jobs, schools or other practices | Add negatives; our negative keywords tool has a starting list |
| Repeated clicks from your own office or a known competitor | Staff checking ads, or a competitor | Add IP exclusions; use the ad preview tool instead of searching |
How does measurement settle the question?
Count signed clients by source. If a keyword brings clicks but never a signed client, pause it, whatever the cause. If it brings signed clients at a cost you accept, a few invalid clicks matter less than they seem. Call tracking and offline conversions make this possible; see our guides to call tracking and tracking signed cases in Google Ads.
Are click fraud tools worth it for a law firm?
Sometimes, after the basics. Many tools count every repeat visit or every visit from a data center as fraud, which inflates the problem, and blocking too broadly can shut out real people on shared networks. Start with Google’s own report, tighter settings and signed-client measurement. If invalid clicks still show up clearly, a tool that feeds IP exclusions into your account can help.
What this means for your firm
- Check the invalid-clicks column monthly and request an investigation when activity looks wrong.
- Fix waste first: networks, location settings, match types and negatives.
- Judge every keyword by signed clients, which settles most fraud worries.

Questions about this guide
Do competitors click a law firm's ads to drain its budget?
It happens, but it is rarer than firms fear, and Google's systems are built to catch repeated clicks from the same people and devices. Look at the invalid-clicks column and at signed clients by keyword before assuming a competitor is the cause.
Should a law firm buy a click fraud blocking tool?
Only after the basics: check the invalid-clicks report, keep ads off placements that bring junk clicks, add IP exclusions for known sources, and measure signed clients by source. Many third-party reports count every repeat visit as fraud, which overstates the problem.
What is the difference between invalid clicks and bad leads?
An invalid click is one Google judges not to come from genuine interest, such as a bot or an accidental tap, and it is filtered or credited. A bad lead is a real person who is not a fit, such as a job seeker or someone outside your practice; negatives and better ad copy fix that, not fraud tools.
How do Local Services Ads handle bad leads?
Local Services Ads bill per lead, not per click, and have their own process for disputing leads that do not fit. Our guide to LSA lead disputes and billing explains it.
