Paid ads aren’t cheap, especially through Google Ads and when you’re spending that much each day, you tend to keep a very close eye on your click-through and conversion rates. But have you ever thought about how many of the clicks that you’re paying for could be fraudulent?
Click fraud isn’t as widespread as it was a decade ago, but it hasn’t gone away, and in 2026, it’s arguably gotten harder to spot. It still drains your budget, and worse, it corrupts your data, which means you end up making decisions based on numbers that were never real in the first place.
Cutting click fraud out of your account does two things: it saves you money every month, and it gives you clean data to actually optimize from.
What is Click Fraud?
Click fraud is a black-hat paid traffic tactic where someone clicks your ads on purpose to benefit themselves, not because they’re an actual potential customer. It usually happens one of two ways:
- A competitor clicks your ads repeatedly to drain your daily budget faster, so their own ads show up more often (and more cheaply) once yours drop off, allowing them to get more and cheaper clicks.
- A website owner clicks the ads running on their own site through the Google Display Network, so they earn more AdSense revenue.
Both result in the same thing for you: higher costs, zero benefit, and data you can’t trust. At scale, this can quietly kill a campaign that would otherwise have been profitable, you just pull the plug because the numbers look bad, without realizing the numbers were fake.
Although this type of fraud can happen in two ways, it’s far more common in the latter whereby website owners click on the ads on their site. This is because it’s easier to get away with, arguably harder to catch and there is a more obvious benefit for the perpetrator. As a result, the large majority of click fraud that happens in Google AdWords is on the Google display network rather than in the search engine ads.
What Does Google do About Click Fraud?
While you might imagine that Google wouldn’t care about click fraud, they get paid either way at the end of the day. But once it becomes a serious problem, they will lose advertisers, and therefore they’ve tackled the problem heavily over the past decade, reducing the amount of fraud by a huge percentage. Here’s their ads safety report detailing how they’re working faster than scammers. To Google, weeding out even the smallest amounts of click fraud is important.
How to Identify & Stop Click Fraud in Your Account
Click fraud rarely shows up as one obvious metric. You need to dig a little to confirm clicks are bogus, otherwise you risk blocking real customers along with the fraud. You’re looking for a pattern: the same person (or a small group) clicking your ads repeatedly with no intent to ever become a customer. To build that case, pull together:
- The IP address: where a click came from
- Timestamp of the click
- Timestamp of any on-site section
- User agent: the device/browser info tied to the click
Here’s how those pieces fit together:
The IP address tells you if the same source is clicking repeatedly. But repetition alone isn’t proof, there’s plenty of real customers click an ad more than once. Check the timestamps next: if clicks are landing in short bursts from the same or similar search terms, that’s a stronger fraud signal.
Then check the action timestamp to confirm the person never converted, and look at the user agent. An IP address only tells you which network the request came from. Maybe it’s a coffee shop, a VPN, or a shared proxy could show several “different” people clicking from what looks like one address.
Run an IP lookup, too. Often you’ll find the address belongs to a proxy provider, meaning those clicks may be coming from multiple real people sharing that connection, in which case, blocking it could cost you real leads, not stop fraud.
How to Stop Click Fraud in Your Account
If you’re not deep in Google Ads day-to-day, this is the kind of thing worth handing to a PPC team that manages this for a living, since misidentifying fraud can cost you real customers. But if you want to tackle it yourself, here are the three techniques that eliminate most of it.
IP Exclusions
Once you’ve confirmed an IP address is the source of fraudulent clicks, block it directly in your campaign settings. Anyone on that network stops seeing your ads and can’t click them anymore.
Keep in mind: a fraudster can switch to a new proxy or IP and start again, so this isn’t a one-time fix. Check for new offenders on a regular schedule.
Exclude Certain Domain Extensions
On the Google display network, you’ll often find that the vast majority of click fraud comes from domain extensions that aren’t typical. For example extensions like (.com, .net or .co.uk) are very common and are less likely to be bought by spammers looking to commit fraud. It’s the less common extensions like (.co.za and .club) that are often used by fraudsters. As a result, many campaign managers simply choose to block non-common extensions entirely.
Exclude Sites from Google Display Network
If you are running ads on the Google display network, you must look through the list of sites you’re advertising on regularly and remove those that are most likely to commit fraud. It’s incredibly easy to tell based on the domain name, quality of the website and the content that it’s serving. Take a guess which website is more likely to commit click fraud:
- A website with a .com domain name, quality content and professional web design.
- A site with a .xxx domain name containing random numbers and letters, terrible web design and gibberish content.
Not that hard to figure it out, right? Spammers tend to be incredibly lazy which is what makes it so easy to catch them out. The second one is the obvious risk. That said, don’t assume a clean-looking domain is automatically safe. Fraud can and does happen on well-designed sites too.
Click Fraud in 2026: What’s Changed
A few years ago, fraud bots were easy to spot: no browsing history, no mouse movement, instant bounces from data-center IPs. Google’s filters caught most of that traffic automatically.
That’s shifted. Industry fraud-monitoring firms now report that AI-driven bots can mimic real browsing behavior, like scrolling, pausing, moving a cursor, while operating from residential IPs that look identical to a real visitor. Independent research on invalid traffic (a category that includes both fraud and non-malicious junk clicks) commonly puts average invalid click rates on Google Ads in the low double digits, though estimates vary a lot by industry and measurement method, so treat any specific percentage as a directional benchmark, not a guarantee for your account.
The bigger risk isn’t just the wasted spend. Google’s Smart Bidding and other automated bidding strategies learn from your conversion data. If bot traffic is quietly “converting” (or even just clicking), the algorithm can start chasing more of that same low-quality traffic, which is why keeping your data clean matters more than it did when this post was first written.
The fundamentals from this post still hold — IP exclusions, domain filtering, and Display Network placement reviews. But if you’re running significant Display spend in 2026, it’s worth pairing manual review with account-level fraud monitoring, since some fraud patterns are no longer visible to the naked eye.
FAQs: Click Fraud on Google Ads
Does Google refund me for fraudulent clicks?
Google’s systems automatically filter and credit some invalid clicks before you’re ever charged. However, this only catches a portion of fraud. Sophisticated bots and manual click fraud from competitors regularly slip through, which is why manual monitoring still matters.
Is click fraud more common on Search or Display ads?
It’s more common on the Google Display Network, since site owners running Display ads have a direct financial incentive (AdSense revenue) to click on ads shown on their own pages.
Can I get in trouble for excluding too many IPs or domains?
No, IP and domain exclusions only stop your ads from showing to those sources. They don’t affect your account standing. Just don’t over-exclude broad categories without evidence, or you risk cutting off real customers along with the fraud.
How much does click fraud typically cost home service advertisers?
There’s no universal number, it depends heavily on your industry, CPC, and whether you run Display campaigns. High-CPC verticals (which many home service categories fall into) tend to be more attractive targets, which is part of why regular account review matters.
