NEW New report: We analyzed 200M ad clicks
Here’s How Much Healthcare Advertisers Are Losing to Click Fraud
- June 29, 2026
Key Takeaways
Key Takeaways - 1,200+ healthcare campaigns analyzed. We monitored more than 1,200 healthcare Google Ads campaigns in Q1 2026 across 200+ global accounts, covering 200,000+ Search clicks and $749K in ad spend.
- Google filters miss 28% of invalid clicks in healthcare ads. Fraud Blocker detected a 10.4% invalid click rate across 200+ accounts, 2.3% higher and 28% more than Google’s own reported figure of 8.1%.
- Healthcare advertisers are losing 8.5 cents per click. At a $3.70 CPC, advertisers in this vertical lose 8.5 cents on every click. On a modest $5k monthly budget, that’s $1,380 lost annually.
- Agencies with a $100k monthly budget can lose up to $27,600 annually to invalid clicks that never convert.
At $3.70 per click, healthcare advertisers don’t pay the highest CPCs in paid search. But, they buy a lot of clicks and run always-on campaigns month after month. At this volume, even a small percentage of invalid traffic can quickly become a budget problem.
Our data shows just how big that budget problem can become, and it scales with your spend and size of campaigns. We analyzed data from Q1 2026 across 200+ global healthcare Google Ads accounts, more than 3 million clicks, and $3.9M in ad spend.
Our findings are detailed below. In addition to the benchmark figures, we also share why click fraud is a persistent problem for healthcare advertisers, the financial impact in actual dollar amounts, and what advertisers can do to protect their budget.
Why is click fraud a problem for healthcare advertisers?
Click fraud exists in every industry that runs paid search. But healthcare advertisers are particularly at risk because of their continuously running ads. There are three reasons for this:
- Always-on campaigns attract predictable fraud: Healthcare has long consideration cycles, which means campaigns run for longer, targeting the same keywords month after month. A bad actor doesn’t need to time an attack around a news event or a seasonal spike; the budgets are predictable, always-on, and constantly a target.
- Competitors are motivated to drain your budgets: Competitor clicks are a risk in high-demand specialties where many providers are bidding on the same high-intent local keywords. Targeted click fraud from rivals can quickly burn a practice’s daily budget, reduce visibility, and make it easier to dominate top positions for the rest of the day.
- High volume of invalid clicks still drain budgets: At an average of $3.70 per click in the US, healthcare advertisers spend less per click, but pay for a lot of clicks. At 3 million clicks analyzed in our dataset alone, even a small percentage of invalid traffic represents a huge loss for advertisers.

What the data shows about click fraud in healthcare
Advertisers in our study saw a 10.4% average invalid click rate as identified by Fraud Blocker.

|---|---|
| Google's reported invalid click rate (global healthcare accounts) | 8.1% |
| Fraud Blocker's detected invalid click rate (same accounts) | 10.4% |
| Difference | 2.3% (28% more than Google reported) |
Source: Fraud Blocker internal data, Q1 2026. Sample: 200+ global healthcare Google Ads accounts.
For the same set of healthcare Google Ads accounts, Google’s average invalid click rate was 8.1%. These are clicks flagged and refunded by Google.
The difference between these two, 2.3% of clicks, are invalid, will never lead to a real conversion, and are not refunded by Google. They are essentially wasted.
That means that for every four invalid clicks Google’s filters caught, roughly one slipped past.
And because healthcare campaigns run continuously year-round, the 2.3% lost will accumulate month over month into substantial wasted spend.

The impact of click fraud on healthcare campaigns stacks: Average CPC in Google search ads for US advertisers in our sample is $3.70 per click. The data shows these advertisers are losing 8.5 cents per click to invalid clicks.
Here’s a table explaining what those losses mean in annual spend across a range of typical ad budgets:
Estimated annual dollar loss by healthcare advertiser size
| Monthly Budget | Annual Budget | Approx. Clicks/Year @ $1.30 CPC | Invalid Clicks at 2.3% Gap | Annual Wasted Spend |
|---|---|---|---|---|
| $3,000 | $36,000 | 9,730 | ~224 | $828 |
| $5,000 | $60,000 | 16,216 | ~373 | $1,380 |
| $10,000 | $120,000 | 32,432 | ~746 | $2,760 |
| $25,000 | $300,000 | 81,081 | ~1,865 | $6,900 |
| $50,000 | $600,000 | 162,162 | ~3,730 | $13,800 |
| $100,000 | $1,200,000 | 324,324 | ~7,459 | $27,600 |
Based on a 2.3% unrefunded invalid click gap and $1.30 average CPC. Source: Fraud Blocker internal data, Q1 2026.
To estimate the impact here, we’ve applied the 2.3% gap to different advertiser sizes. We see that even small advertisers spending $3k monthly on Google Ads can still lose $828 every year to click fraud.
5 critical ways click fraud impacts healthcare advertisers
In healthcare, click fraud creates a positive feedback loop problem that isn’t immediately visible in standard reports.
Click fraud → bad data → bad bids → more wasted spend → harder to detect fraud → higher rates of click fraud. Everything compounds into more than just a budget drain.
Here are the biggest impacts to healthcare advertiser accounts that we see.
1. Wasted ad spend grows with every campaign run
Even though healthcare CPCs are modest, advertisers run campaigns at scale, across multiple services, geographies, and audience segments. That means the losses will grow with every campaign. Advertisers in this vertical lose approximately 2.3% of their budget to invalid clicks that Google never refunds. On a $5,000 monthly budget, that’s $115 gone every month; over $1,300 a year.
2. Long-term healthcare campaigns are optimized with corrupt data
Healthcare campaigns typically run year-round, which means your team is constantly making incremental optimization decisions. These depend on performance data that invalid clicks can corrupt. Fake clicks will inflate click volume without contributing any intent, and, thanks to low CPCs, corrupted data can accumulate for months without raising any red flags.
The result is that optimizations are skewed as campaigns are tuned using the wrong data, wasting even more budget on wrong targeting.
3. Click fraud undermines your Smart Bidding
Google’s automated bidding strategies treat your conversion data to define quality traffic. When a consistent portion of clicks are invalid and never convert, Smart Bidding interprets this as a targeting or relevance problem and begins adjusting.
If you’re running a large number of campaigns at once, this misattribution becomes particularly hard to nail down and your bidding logic slowly drifts toward poor leads. You end up spending on more and more clicks with a low chance to convert.
4. Lowered conversion rates distort how you evaluate your campaigns
Every invalid click that doesn’t convert pushes reported conversion rates lower. That means, evaluating your Google Ads campaigns’ cost against benchmarks immediately shows the campaigns are poor performers. Especially with healthcare campaigns that have long patient journeys and non-linear conversion paths.
So, the campaigns get restructured, paused, or defunded based on numbers that are fundamentally flawed thanks to click fraud.
5. Consistent low levels of fraud are harder to spot
Healthcare isn’t typically the target of the aggressive, concentrated competitor click fraud that legal advertisers face. More likely, bad actors will generate consistent low volumes of invalid clicks across your long-running campaigns.
Losing 8.5 cents on every click doesn’t look alarming. But annualized, those losses add up quickly. For a monthly budget of $5,000, that’s $1,380 annually. Enough to buy an additional 370+ clicks.
What these click fraud numbers means for healthcare advertisers
If you are an agency running Google Ads across multiple healthcare clients, a 2.3% gap at the account level may fall within what you’d typically allocate as a testing budget; the kind of variance you’d expect to absorb while optimizing.
But across a book of clients running always-on campaigns, it adds up. An agency managing 10 healthcare clients at an average $5,000 monthly spend is losing roughly $1,150 monthly to preventable click fraud. That’s over $13,800 a year. That budget could be reallocated to higher-performing campaigns or used to demonstrate stronger ROI to clients on the same retainer.
For in-house marketers at larger health systems or multi-location groups, the same logic applies here, except, your campaigns are potentially losing even more money. At $25,000 a month, the 2.3% gap represents over $6,900 in annual wasted spend.
