How to report click fraud to Google in 2025: A step-by-step guide to protect your Ad budget

Click fraud is a growing threat to businesses that rely on Google Ads to drive traffic and conversions.

It occurs when unauthorized clicks inflate your ad costs without genuine user interest, draining budgets, distorting performance data, and reducing ROI.

According to Statista, digital advertising fraud caused losses estimated at $84 billion in 2023, expected to rise to $172 billion by 2028.

This guide covers everything you need to know about recognizing click fraud, how to report click fraud to Google, and practical steps to prevent it from impacting your campaigns.

What is click fraud?

Click fraud involves repeated, invalid clicks on online ads generated by:

• Competitors: Rivals click your ads to exhaust your budget prematurely.
• Bots and automated scripts: Software mimics human clicks to bypass detection.
• Click farms: Groups paid to click ads repeatedly for profit.
• Accidental clicks: Misplaced ads or mobile interface issues causing unintentional clicks.
• Malicious publishers: Website owners using Google AdSense to generate fake clicks and inflate revenue.

Why report click fraud to Google?

Reporting click fraud helps you:

• Recover lost budget: Google credits advertisers for invalid clicks once confirmed.
• Improve campaign accuracy: Google refines targeting algorithms with your reports.
• Protect your brand reputation: Avoid misleading metrics that lead to poor marketing decisions.
• Deter fraudsters: Reporting signals that suspicious activity is monitored, discouraging future fraud.

Google maintains a multi-layered fraud detection system including automated filters, manual review teams, and partnerships with organizations like the Trustworthy Accountability Group (TAG).

However, advertiser vigilance and reporting remain crucial.

How to identify click fraud in your Google Ads campaigns

Watch for these key indicators:

• Sudden CTR spikes: Unexplained jumps (e.g., 3%-20%) without matching conversions.
• High bounce rates: Visitors quickly leave, especially if PPC bounce surpasses organic traffic.
• Duplicate IP clicks: Many clicks from the same IP in a short period.
• Click vs. visit discrepancies: More clicks recorded than actual visits in Analytics.
• Low conversion rates: Clicks that do not result in conversions below the industry average (~4.4%).
• Unusual click locations/times: Clicks from outside your target area or at odd hours.

Early detection of click fraud enables you to act promptly. Monitoring your campaign measures will help you identify suspicious trends that reflect fraud.

How to report click fraud to Google: Step-by-step guide

If you suspect click fraud in your Google Ads campaign, you can report click fraud to Google by taking the following steps:

Step 1. Collect evidence

Gather minute facts of suspicious behaviour before handing in a report.

This may include:

• Screenshots of unusual CTR or bounce rate spikes.
• Analytics data shows that clicks do not match site visits.
• IP addresses involved and their location/time stamps.
• Conversion data anomalies.

Step 2: Invalid activity credits checks

Google automatically removes substantial numbers of invalid clicks and credits undetected invalid activity.

To check credits:

• Sign in to your Google Ads account.
• Tap tools & settings in the upper-right corner.
• Going to billing, click on transactions.
• Search for “Invalid Activity” to check whether Google has already compensated you for Invalid clicks.

Step 3: File a click fraud report

In case you suspect that click fraud continues, then submit a report to Google directly:

• Go to the Google Ads Invalid Clicks Contact Form.
• Enter your Google Ads (customer) ID (located top right of the account).
• Describe the click fraud you suspect, providing evidence that you obtained.
• Provide date range, campaign and ad group impacted.
• Complete the form and save the confirmation email.

A team of specialists will examine the report you submitted, a process that may take several days due to the high volume of data they process.

Provided the clicks have been declared invalid, you will receive a credit into your account.

Step 4: Track report progress

The status of legal reports (e.g. copyright violations) can be monitored on the Report Content Dashboard at Google.

In the case of click fraud reports, Google tends to send updates over email.

Step 5: Follow up if necessary

If you have not received a response after a week, you may contact Google Ads support by visiting the Help Center or dialling their support line (available in certain areas).

Give your case ID to speed up the process.

Preventing click fraud: Proactive strategies

The best way to deal with click fraud is to prevent it.

These measures will help limit invalid clicks.

1. IP Exclusions: Repeated clicks can be avoided by blocking suspicious IPs in Google Ads under Settings > IP Exclusions.
2. Enhanced audience targeting: Limit the audience using demographics, their interests, or the destination to minimize irrelevant clicks.
3. Negative keywords: Avoid words such as free or cheap to prevent the cheap clicks.
4. Regular monitoring: Google Ads and Analytics alerts could be configured to report such anomalies as a high CTR or a high bounce rate.
5. Conversion tracking: Consider using Google Ads conversion tracking to focus on actual user actions and identify discrepancies related to fraud.
6. Tool to detect fraud: Invest in the ClickPatrol detection tool, which allows non-stop invalid clicks blocking.
7. Bidding adjustments: Instead of broad matching, use Exact or Phrase Match keywords so that the company is exposed to fewer fraud-prone searches.

Google’s role in combating click fraud

Google uses a multi-layered system that identifies and stops click fraud to make sure that advertisers are not billed for invalid clicks.

They include:

1. Automated filters: Real-time detection using IPs, click frequency, and behaviour.
2. Manual reviews: To ensure that operations are not violating the rules of the company, a specific team of specialists handles the suspicious cases, including botnets or click farms, and prevents their use.
3. Partnerships: Technology companies, such as Google, have been working together to solve ad fraud problems and build industry standards, with organizations such as the Trustworthy Accountability Group (TAG).
4. AdSense verification: The sites used in the Google AdSense program are closely vetted to ensure that only legitimate advertisers use the sites to avoid invalid clicks.
5. Although these measures can be taken, Google admits to the possibility of some invalid clicks escaping such measures.

That is why it is essential to report alleged click fraud to improve their detection mechanisms.

Protecting Google Ads campaigns from the impacts of click fraud

Click fraud is a costly issue for Google Ads campaigns, costing Google billions of dollars annually and distorting metrics with fake clicks.

Advertisers can save their budgets and maximize their performance by detecting indicators of suspicious traffic (such as CTR spikes and high bounce rates), reporting similar campaigns to Google, and taking proactive measures.

Advanced detection systems and blocking techniques, such as IP exclusions and fraud detection tools, enable Google to mitigate risks.

Remain active, report early on click fraud, and maximize your advertising spend.
