Google Local Services Ads vs Search Ads vs Performance Max: Which Is Safest from Fraud?

If you run a home services business — plumbing, HVAC, roofing, electrical, or similar trades — you now have three main ways to advertise on Google: Local Services Ads (LSAs), traditional Search Ads, and Performance Max campaigns. Each works differently, costs differently, and exposes your budget to very different levels of click fraud.

Most “LSA vs Search Ads” guides focus on cost per lead, ease of setup, or reach. None of them talk about fraud risk. That’s a significant oversight, because the ad type you choose directly affects how vulnerable your budget is to fraudulent clicks, fake leads, and wasted spend.

This guide compares all three ad types through a fraud safety lens — helping you understand which is safest, which is riskiest, and how to protect whichever combination you use.

The Three Ad Types: A Quick Overview

Before diving into fraud risk, here’s what each ad type actually is and how it works. If you’re already familiar with these, skip ahead to the fraud comparison.

Google Local Services Ads (LSAs)

Local Services Ads appear at the very top of Google Search results, above regular ads. They show your business name, Google rating, years in business, and a “Google Guaranteed” or “Google Screened” badge (depending on your industry and verification level).

The key difference from other ad types is the pricing model. With LSAs, you pay per lead rather than per click. When someone contacts you through your LSA listing — either by calling or sending a message — that’s when you’re charged. If they just see your listing or even click on it to view more details, you don’t pay.

Google also runs a verification process for LSA businesses, checking licences, insurance, and background checks. This creates a higher barrier to entry but also provides a trust signal to consumers.

Google Search Ads

Search Ads are the traditional Google Ads format that most advertisers know. You bid on keywords, write ad copy, and your ad appears in search results when someone searches for those terms. You pay per click (CPC) — every time someone clicks your ad, you’re charged, regardless of whether they become a lead.

Search Ads give you the most control of any ad type. You choose exact keywords, write specific ad copy, set geographic targeting, control your budget by campaign and ad group, and can see detailed performance data for every element. This control makes Search Ads the most transparent option, but also the most directly exposed to click fraud because every click costs you money.

Performance Max (PMax)

Performance Max campaigns run your ads across all of Google’s advertising networks at once — Search, Display, YouTube, Gmail, Discover, and Maps. Google’s AI handles most of the targeting, creative decisions, and budget allocation across these networks.

PMax offers the broadest reach and the least manual work, but also the least transparency. You can’t see exactly where your ads appear or who’s clicking them with the same granularity as Search campaigns. For a detailed analysis of PMax fraud risks, see our complete guide to Performance Max click fraud.

Fraud Risk Comparison: Head to Head

Here’s how the three ad types stack up on the factors that matter most for fraud exposure.

Cost model and fraud impact

LSAs: Pay per lead. Because you only pay when someone contacts you, traditional click fraud (clicking your ad to drain your budget) doesn’t apply in the same way. Nobody can waste your budget by simply clicking on your listing. This is the single biggest advantage LSAs have for fraud protection.

Search Ads: Pay per click. Every click costs money, making Search Ads the most directly exposed to click fraud. A competitor, bot, or click farm can drain your budget by clicking your ads without ever intending to become a customer.

PMax: Pay per click (across all networks). Like Search Ads, PMax charges per click. But because PMax spreads your budget across Display, YouTube, and other networks where fraud rates are historically higher than on Search, the effective fraud exposure per pound spent can be greater.

Transparency and detection ability

LSAs: Limited reporting. LSA reporting is relatively basic — you see leads received, costs, and some performance metrics, but detailed click-level data isn’t available. The upside is that the pay-per-lead model makes most click fraud irrelevant. The downside is that when fraud does occur (fake leads), the limited reporting makes it hard to analyse patterns.

Search Ads: High transparency. Search Ads provide the most detailed reporting of any Google ad type. You can see which keywords triggered your ads, search term reports, geographic data, device data, and time-of-day breakdowns. This makes it the easiest ad type to manually investigate for suspicious click patterns.

PMax: Low transparency. PMax provides aggregated metrics with limited breakdowns by channel, placement, or search term. Fraud signals that would be obvious in a Search campaign can be hidden inside PMax’s bundled reporting. This makes PMax the hardest ad type to manually audit for fraud.

Advertiser control

LSAs: Minimal control. You set your budget, service areas, and job types. Google handles everything else — you can’t choose keywords, write ad copy, or control when your ads appear in the same detail as other ad types.

Search Ads: Maximum control. You control keywords, bids, ad copy, extensions, scheduling, geographic targeting, device targeting, and placement. Crucially, you can also implement IP exclusions (up to 500 per campaign plus 500 at account level) to block known fraudulent sources.

PMax: Limited control. You provide assets and audience signals, but Google’s AI makes most targeting decisions. You can create placement exclusion lists for Display and YouTube, but you can’t control Search keyword targeting or most other elements with the same precision as standard Search campaigns.

Fraud Risk by Ad Type: The Full Picture

Local Services Ads: Lowest traditional fraud risk, but not zero

LSAs are the safest ad type from traditional click fraud because the pay-per-lead model means clicks don’t cost you anything. A competitor clicking your LSA listing all day won’t drain your budget.

However, LSAs face a growing threat: fake lead fraud. This includes bot-generated phone calls using spoofed numbers, automated form submissions with fake contact details, and competitors submitting fake leads to inflate your costs and waste your time following up on non-existent prospects.

Google does allow you to dispute LSA leads you believe are invalid, and they’ll review and potentially credit your account. But the dispute process requires manual review of each lead, and not all disputes are resolved in your favour. The time spent chasing fake leads is never recovered.

For home services businesses, fake LSA leads are particularly frustrating because you might send a technician to a fake address or spend time calling a number that doesn’t connect — wasting operational resources on top of the lead cost.

Search Ads: Highest click fraud exposure, but most controllable

Search Ads have the highest direct exposure to click fraud because every click costs money and click fraud is the most established, most prevalent form of ad fraud. In competitive home services markets, competitor clicking is common — a rival plumber or HVAC company clicking your ads a few times a day can steadily erode your budget.

The silver lining is that Search Ads give you the most tools to fight back. You can review search term reports to spot irrelevant traffic, use IP exclusions to block known bad actors, implement negative keywords to reduce exposure, and analyse time-of-day and geographic patterns to identify suspicious activity. Combined with automated click fraud protection, Search Ads can be well-defended.

The key metric to watch is your conversion rate. If clicks are rising but conversions aren’t, that’s a sign of click fraud that warrants investigation.

Performance Max: Highest overall fraud risk

Performance Max carries the highest fraud risk of the three ad types for several compounding reasons.

First, PMax runs across Display Network and YouTube, where fraud rates are significantly higher than on Google Search. A portion of your budget is automatically allocated to these higher-risk networks.

Second, PMax’s limited transparency means fraud is harder to detect. You can’t easily spot the click patterns, geographic anomalies, or engagement drops that would be visible in a Search campaign.

Third, PMax’s AI optimisation can be poisoned by fraudulent clicks. When bots or competitors click your PMax ads, the algorithm learns from that bad data and may optimise towards more fraudulent traffic — creating a feedback loop that degrades performance over time.

Fourth, Google’s invalid click protection is less effective on PMax because the multi-network structure fragments fraud signals across channels.

The Recommended Approach for Home Services Businesses

Based on the fraud risk profiles, here’s the strategy that most effectively balances reach, leads, and fraud protection for home services businesses.

Lead with LSAs for core lead generation. LSAs carry the lowest fraud risk and the highest trust signal (the Google Guaranteed badge). For your primary service area and core service offerings, LSAs should be your first investment. Dispute any suspicious leads promptly through Google’s dispute process.

Run Search Ads for high-value keywords with full protection. For specific keywords where you want maximum control and visibility — emergency services, high-value jobs, specific service types — traditional Search campaigns give you the transparency and control to manage fraud effectively. Combine this with automated click fraud protection from ClickGuardian to block competitors and bots in real time.

Use PMax as supplementary reach, not your primary campaign. PMax can find incremental leads that LSAs and Search campaigns miss, particularly through Display and YouTube. But don’t rely on it as your only campaign type. Run it alongside Search campaigns so you have a control group, review placement reports regularly, and ensure click fraud protection covers your PMax traffic.

Protect all three. Even LSAs aren’t completely fraud-free, and Search and PMax campaigns require active protection. Automated click fraud detection monitors all campaign traffic and blocks fraudulent sources before they can inflict further damage.

Frequently Asked Questions

Are Local Services Ads safe from click fraud?

Local Services Ads are significantly safer from traditional click fraud than Search Ads or Performance Max because LSAs use a pay-per-lead model rather than pay-per-click. Competitors or bots clicking your LSA listing won’t cost you money. However, LSAs are not completely fraud-free — they face a growing threat from fake lead fraud, where automated systems submit fake contact requests or generate spoofed phone calls. Google allows you to dispute suspicious leads, but the dispute process is manual and doesn’t always result in a credit.

Which Google ad type is best for plumbers and HVAC businesses?

Most home services businesses get the best results from a combination of all three ad types, each serving a different role. Local Services Ads provide the lowest fraud risk and highest trust signal for core lead generation. Search Ads give maximum control and transparency for high-value keywords. Performance Max offers supplementary reach across Google’s networks. The key is to protect all three with click fraud detection, particularly Search Ads and Performance Max which are directly exposed to click fraud.

Is Performance Max safe to use for my business?

Performance Max can be effective, but it carries the highest fraud risk of Google’s three main ad types due to its limited transparency, inclusion of high-fraud Display Network placements, and vulnerability to algorithm poisoning from fraudulent clicks. If you use Performance Max, run it alongside standard Search campaigns rather than as your sole campaign type, review placement reports regularly, and use automated click fraud protection to filter bad traffic before it pollutes your campaign data.

Can competitors drain my budget by clicking my Google Ads?

Yes. On Search Ads and Performance Max campaigns, competitor clicking is one of the most common forms of click fraud in local service markets. Every click a competitor makes costs you money and takes budget away from reaching genuine customers. Google’s automated invalid click filters catch some obvious repeat clicking but miss sophisticated competitor fraud from real devices on residential networks. Automated click fraud protection tools like ClickGuardian detect competitor clicking through behavioural analysis and device fingerprinting, blocking the source before further clicks occur. For more detail, see our guide on how to spot and stop competitor clicking.

How much does click fraud cost home services businesses?

Click fraud costs vary by industry, location, and competition level. In home services industries where CPCs typically range from £5 to £30+, even a modest 15–20% fraud rate on Search and Performance Max campaigns can translate to hundreds or thousands of pounds wasted per month. Over a year, cumulative losses can easily exceed £10,000 for a single business.
