A retailer losing a click on a $1.20 keyword shrugs. A personal injury firm losing a click on a keyword that costs more than a decent dinner does not get to shrug. Multiply that by a few dozen clicks a week and you are looking at a line item that would pay for a paralegal. This page covers what click fraud actually looks like in a legal account, who is generating it, what Google does and does not do about it, and which fixes are worth your time. No invented statistics. If a number cannot be verified, you will get the mechanism described instead. ## Why click fraud targets law firms specifically Three things make legal advertising an unusually good target. **The clicks are expensive.** Legal has sat at or near the top of the cost-per-click rankings in paid search for as long as anyone has been publishing those rankings. Google does not publish official vertical CPC tables, and the figures floating around blog posts are mostly recycled guesses, so treat any specific dollar figure you see with suspicion. What is not in dispute is the ranking. Criminal defense, personal injury, mass tort, and DUI keywords cost a lot per click. **The competitive set is small and local.** A firm in a mid-sized city competes against maybe eight or ten other firms for the same terms. Everyone knows who everyone is. That is very different from an e-commerce advertiser competing against a national field they will never meet. When the competitor is a known quantity down the street, the temptation to burn their budget is more immediate. **Budgets are capped daily.** This is the part most partners miss. Your campaign does not run on a monthly budget that slowly drains. It runs on a daily cap. Once the day's budget is spent, your ads stop serving. That means a modest number of worthless clicks early in the morning can take you off the auction for the rest of the day, including the hours when actual injured people and actual arrested people are searching. The direct cost of the fraudulent clicks is the smaller half of the damage. The bigger half is the visibility you did not get. ## Who is actually generating the clicks The picture people have in their head is a competitor sitting at a desk clicking their ad over and over. That happens, and it is more common in legal than in most verticals, but it is not the whole story. ### Competitors and their staff Sometimes deliberate. Often not. A paralegal checking what the firm across town is advertising this month will click the ad rather than type the URL, because that is what people do. Do it once a week for a year and you have spent a meaningful amount of your competitor's money without ever intending harm. Deliberate budget burning also happens, and it tends to look different: same source hitting repeatedly, concentrated in the first hours of the ad schedule. We cover the tells in detail in our guide on [how to tell if a competitor is clicking your law firm's ads](/competitor-clicking-my-ads/). ### Lead resellers and marketing agencies Firms that sell legal leads have an interest in your paid search performing badly. If your cost per acquisition from Google Ads looks terrible, their per-lead pricing looks reasonable by comparison. The same logic applies to agencies pitching you on their services. This is harder to prove than competitor clicking and we are not going to pretend otherwise, but the incentive is there and the pattern shows up in accounts. ### Bots and automated traffic The largest share by volume, and the least personal. Scrapers, competitive intelligence tools, ad verification crawlers, malware-driven click farms, and traffic sold through low-quality placements on the Display Network and search partners. None of it has any intent to hire a lawyer. Much of it is not even a person. We go deeper on the mechanics in our overview of [bot traffic in Google Ads](/bot-traffic-google-ads/). ### Curious non-clients Law students, journalists, people researching their own case who will never hire anyone, opposing parties checking out your firm. Not fraud in any legal sense. Still a click you paid for at legal-vertical prices. ## What click fraud looks like in a law firm account You rarely see a smoking gun. You see a set of patterns that individually could be innocent and collectively are not. - **Clicks with near-zero time on site.** Someone arrives and leaves before the page finishes rendering. Consistently, from the same sources. - **Budget exhausted early with nothing to show.** Daily cap hit by mid-morning, impression share dropping off a cliff in the afternoon, no form fills and no calls. - **Clicks clustered outside the hours anyone would contact a lawyer.** Legal intake has a rhythm. Traffic that ignores it is worth a look. - **A geographic profile that does not match your service area.** Location targeting is leakier than most people assume, particularly the default setting that includes people merely showing interest in your area. - **Rising cost per click with flat or falling call volume.** The single most reliable signal at the account level. - **Repeat clicks from the same source across days.** Genuine prospects click once, maybe twice. They do not click every weekday at 9am. None of these proves anything on its own. A firm running a brand campaign will legitimately see short sessions. Patterns matter more than incidents. ## What Google actually does about click fraud for law firms Google filters some invalid traffic automatically and issues credits for it, usually visible as an invalid clicks line in your account. That system works, up to a point, and it costs you nothing. Here is the limitation. Google does not disclose what its detection criteria are. You cannot see which clicks were flagged, why, or what fraction of the bad traffic was caught. You get a credit and no explanation. That means you have no way to audit it and no way to know what got through. Our page on [Google's invalid click refunds](/google-invalid-click-refunds/) covers what the credits cover and what they do not. Local Services Ads work on an entirely separate track. LSA charges per lead rather than per click, and it uses a lead dispute process, not the invalid click credit system. Different rules, different timelines, different outcomes. Worth reading our breakdown of [what Google refunds and does not refund on Local Services Ads](/local-services-ads-fraud/) before you assume your LSA spend is protected by the same machinery. ## Fixes that work, and fixes that do not ### IP exclusions: useful, limited Google Ads allows up to 500 IP address exclusions per campaign. That is a real tool and you should use it. It is also a fixed list that does nothing against a residential IP that changes, a mobile connection, or anyone using a VPN. Treat it as one layer, not a solution. See our guide to [Google Ads IP exclusions](/google-ads-ip-exclusions/) for how to build and maintain the list properly. ### Negative keywords: solves a different problem Negative keywords control which search queries can trigger your ad. They have no idea who is behind the click. A competitor searching your exact target term and clicking your ad is unaffected by any negative keyword list you could build. They are still worth maintaining, for reasons we lay out in [what negative keywords actually stop](/negative-keywords-click-fraud/), but they are not a fraud control. ### Tightening geography and scheduling Switch location targeting to presence only rather than presence or interest. Cut search partners and Display from search campaigns unless you have a specific reason to keep them. Cheap, fast, worth doing before anything else. ### Automated blocking The practical answer for most firms is software that watches click behavior in real time and adds the sources worth excluding to your campaign exclusions automatically, so the traffic stops arriving rather than being argued about after the fact. It is the only approach that scales past a handful of obvious offenders. That is what [click fraud protection](/click-fraud-protection/) is built to do. ## What this costs you if you ignore it Run the number for your own firm rather than trusting anyone's industry average. We walk through the arithmetic in detail in our breakdown of [what one fraudulent click costs in criminal defense and personal injury](/cost-of-fraudulent-click-legal-ppc/). Take your actual cost per click from your account, decide what fraction of your clicks produced no meaningful engagement, and multiply. Then add the cases you did not see because your budget ran out before lunch. For most firms the second figure is larger than the first, and neither shows up as a line item anywhere. It shows up as a quarter where intake was slower than it should have been and nobody could say exactly why. Click fraud in law firm accounts is not usually dramatic. It is a slow leak in the most expensive pipe you own. Worth knowing where it is.
