Not every Google Ads click is from a real lead. Some are competitors. Some are bots. And some come from click farms designed to drain your budget before a real prospect ever sees your ad.
For home services businesses (HVAC companies, plumbers, electricians, and similar trades), click fraud rarely makes headlines. But it exists in the industry, quietly siphoning budgets and derailing campaigns that should perform better.
To understand the scale of the problem, Fraud Blocker analyzed data from Q1 2026 across 100+ home services Google Ads campaigns, representing over $3 million in ad spend.
We found home services advertisers face a 12.5% invalid click rate, versus the 8.6% Google reports for the same accounts. Here’s the breakdown.
We found a consistent gap between what Google reports and actual invalid click rates. Here’s the breakdown.
Why home services advertisers struggle with click fraud
When a homeowner searches for “emergency plumber” or “24-hour AC repair”, they need a solution immediately. That makes these searches high-intent and valuable, driving up competition and CPC in Google Ad auctions.
The resulting competition creates a clear incentive for rival businesses to drain your daily budget by clicking your ads and knocking your campaign out of auction for the rest of the day.
Home services advertisers are also targets for bots and click farms, particularly during peak seasons when demand and bids are at their highest. A prime example is HVAC companies in summer: higher bids mean each fraudulent click is more profitable for bad actors, and more damaging for your campaigns.
How much click fraud is in home services?
We analyzed a sample of home services Google Ads accounts to measure the industry’s invalid click rate. Advertisers in our dataset saw a 12.5% invalid click rate compared to 8.6% reported by Google for the same accounts.

The invalid clicks Google caught were refunded, but the 3.9% gap represents clicks Google missed entirely. These were clicks from bots and bad actors that would never have converted.
Put another way, Google missed 1 in every 3 invalid clicks in home services ads.

That might sound small, but not all clicks convert, and invalid clicks still consume budget that could have reached a real prospect. For home services where a single conversion can mean a $5,000 roofing contract, every wasted click is a missed opportunity.
Here’s a table illustrating how much a home services advertiser loses to invalid clicks, based on estimated monthly budget.
Estimated annual dollar loss by home services advertiser size
| Monthly Budget | Annual Spend | Annual Clicks @ $4.00 CPC | Unrefunded Invalid Clicks | Annual Loss |
|---|---|---|---|---|
| $1,000 / mo | $12,000 | 3,000 | ~117 | $468 |
| $5,000 / mo | $60,000 | 15,000 | ~585 | $2,340 |
| $10,000 / mo | $120,000 | 30,000 | ~1,170 | $4,680 |
| $25,000 / mo | $300,000 | 75,000 | ~2,925 | $11,700 |
| $100,000 / mo | $1,200,000 | 300,000 | ~11,700 | $46,800 |
Based on avg. CPC of $4.00 and an unrefunded invalid click rate of 3.9% of spend. Invalid click rate derived from Fraud Blocker dataset analysis.
The estimated loss here is based on a modest business’ Google Ads budget. But the same numbers work whether you’re a local roofing contractor with a modest $500 monthly budget or a multi-location HVAC company spending $30k/month.
Impact of click fraud on home services advertisers
Click fraud in home services isn’t as complicated as we find it in industries like finance or legal. However, Google’s filters still miss 45% of these clicks, and left unchecked, they can derail your campaigns. Here’s how:
1. Competitor clicks drain your budget before peak hours
A rival who clicks your ads repeatedly in the early morning can exhaust your daily budget before high-intent prospects even start searching. By 9am, your ads are gone from auction, and your competitors are the only ones visible.
And because these searchers are ready to act, visibility in this window is critical. A user who clicks through to a competitor’s landing page may convert, and you lose the lead.

2. Click fraud does more damage in peak season
Home services lead volume can increase by 2-5x, sometimes 10x during the busy season (summer and winter peaks for HVAC companies and storm season for roofing contractors).
Maximizing budget and opportunities during this window is critical in home services, and runaway invalid clicks can derail your campaigns more than some other sectors.
3. Every wasted click still costs you in ad spend
When a bot or bad actor clicks your ad, they land on your site and bounce immediately; but Google still bills you for the click. There was never any chance of a conversion, and you pay in full regardless.
The damage is double: a high-value lead goes to a competitor, and the budget that could have reached a real prospect is gone. Our data shows 3.9% of clicks in home services fall into the category of traffic Google’s own filters miss entirely.
For a business spending $2,500 a month on Google Ads, that’s over $1,100 a year on traffic that will never become a job.

The real cost for agencies and small businesses
For agencies managing Google Ads across multiple home services clients, a 3.9% loss at the account level can look insignificant. But it builds quickly across a portfolio. An agency managing 10 clients at $5,000/month ($600,000 in annual spend) is losing roughly $23,400 a year to unrefunded invalid clicks. That’s budget clients paid for, which no amount of campaign optimization can recover.
There’s also a cost that doesn’t show up in spend reports. When campaigns underperform and click fraud has never been part of the conversation, your agency’s performance gets questioned. That’s a harder conversation than just budget.
For small business owners spending about $1,000 monthly, $468 a year in lost spend is easy to dismiss until you consider what it actually represents: real clicks your business couldn’t buy that likely went to a competitor instead.
How Fraud Blocker protects home services advertisers
Businesses lost $84 billion to ad fraud in 2023, with projected losses reaching $170 billion by 2028. In home services alone, our data shows advertisers are losing 15 cents on every click to invalid traffic Google never refunds.
Google’s filters are the first line of defense for your ads and catch most invalid clicks. But they still miss 1 in every 3, which means wasted spend for your campaigns. Catching what Google misses requires a second layer of fraud protection.
Fraud Blocker works alongside your Google Ads campaigns to catch what Google misses and block bad actors in real time, so your budget reaches prospects that can actually convert.

Frequently Asked Questions
If you’re running Google Ads in home services, you’re likely affected. Our data found a 12.5% invalid click rate across 100+ US home services accounts, regardless of budget size. Look for signs like budget exhausting faster than expected, high bounce rates from paid traffic, and clicks that don’t produce leads.
Yes. A home services business spending $1,000/month loses an estimated $468 a year to unrefunded invalid clicks. Bigger advertisers spending $100,000/month lose $46,800 annually. The percentage loss is the same at every budget level, but smaller advertisers have less margin to absorb it.
Google’s filters catch the most obvious invalid traffic and refund those clicks, but they miss roughly 1 in every 3 invalid clicks in home services. Fraud Blocker’s filters are designed to catch more sophisticated invalid traffic that slips through Google’s filters.
Indirectly, yes. Invalid clicks inflate your click volume without producing conversions, which pulls down your conversion rate and skews your cost-per-conversion data. If you’re using automated bidding, Google is optimizing based on that distorted data, which can lead to poor bid adjustments and wasted budget over time.
