Are Competitors Clicking Your Ads? 7 Telltale Signs and How to Stop Wasting Your Budget

Rivals can burn through your ad spend by repeatedly clicking your ads. Spot this through unusual CTR peaks, poor conversion rates, and IP address patterns. Stop it with IP exclusions, Google's inbuilt filters, and managed protection that covers Performance Max and advanced SIVT.

What Exactly Is Competitor Click Fraud?

Competitor click fraud happens when a rival deliberately clicks your pay-per-click ads to eat up your daily budget, forcing your campaigns to stop showing. This dishonest tactic can cost companies thousands of pounds every month. It is often carried out using automated bots, residential proxies, click farms, or even staff manually clicking from a competitor's office.

Industry estimates suggest that between 14 and 25 per cent of all paid clicks could be invalid, with competitor clicks making up a hefty slice of that. The growing sophistication of click farms and AI-generated traffic makes this type of fraud much harder to spot.

7 Warning Signs That a Competitor Is Clicking Your Ads

• 1. A sudden surge in clicks with zero conversions: Your CTR doubles overnight, but conversions either flatline or drop off.
• 2. Clicks from irrelevant geographic locations: You see traffic from cities you do not target, or from the area where your competitor is based.
• 3. Repeated clicks from a single IP address: The same IP hits your ad multiple times within just a few minutes.
• 4. High bounce rate and very short time on site: Visitors leave straight away, which suggests either non-human traffic or malicious intent.
• 5. Clicks happening at odd hours: A lot of activity late at night or over the weekend, when genuine customers are less likely to be browsing.
• 6. Anomalies in your ad schedule: Your budget runs out much sooner than it used to, especially just after a competitor launches a new campaign.
• 7. Low conversion rate despite high-quality traffic: If your landing pages are well optimised but conversions stay stubbornly low, fraud could well be the culprit.

How to Investigate Suspected Competitor Clicks

Kick things off by checking your Google Ads account for anything out of the ordinary. Head to Campaigns, then Columns, then Modify columns, and tick the boxes for Clicks, Impressions, CTR, Avg. CPC, and Conversions. Keep an eye out for campaigns where the CTR is sky high but conversions are low. After that, make use of the IP exclusion feature to block any dodgy IPs you've spotted.

Now, dig into your server logs or bring in a tool like Google Analytics to see what users are actually doing. Watch for patterns: the same user agent cropping up, repeated clicks from the same IP range, or traffic coming from data centres. You could also set up a honeypot page or bring in a click fraud detection service to automatically flag and block any malicious traffic.

Quick Actions to Thwart Competitor Clicks

1. Switch on Google's built-in safeguards: Activate Automatic invalid traffic filtering (it's on by default) and use IP exclusions to block IPs you already know are problematic. Bear in mind, though, that this only catches the most obvious fraud.

2. Bring in click fraud detection software: Services like Unled Network offer managed protection that covers Performance Max campaigns (which self-serve IP blockers can't touch because of Google's API restrictions) as well as modern SIVT such as residential proxies, click farms, and AI-agent traffic, which has grown around 78 times year on year.

3. Tweak your ad schedule and targeting: Narrow your audience to cut out competitor locations, or set your ads to run only during peak business hours.

4. Ask Google for a refund: If you've got proof of invalid clicks, you can put in a refund request. Managed services often take care of this for you, recovering between 10% and 20% of wasted spend.

Why Self-Serve IP Blockers Can't Handle Modern Click Fraud

Old-school IP blocklists are no match for today's clever fraudsters. Competitors use residential proxy networks that cycle through IPs constantly, so you can't block them manually. Click farms run thousands of real devices, each with its own IP. And AI-generated traffic mimics human behaviour, slipping past simple pattern checks.

On top of that, Google blocks third-party access to Performance Max campaigns through the API, meaning self-serve tools can't protect those ads. Managed services like Unled Network use advanced machine learning and human analysis to spot and block these threats in real time, covering every type of campaign, including PMax.

Long-Term Prevention: Building a Strong Defence

Beyond the quick fixes, take a proactive approach. Regularly audit your click data for anything unusual, and think about using a managed click fraud protection service that handles refund recovery for you. That way, you stop the fraud and get your lost budget back.

Make sure your team knows the signs of click fraud, and set up automated alerts for any suspicious activity. Lastly, keep up with fraud trends. AI-driven traffic is changing fast, and only dedicated protection can keep up.
