Competitor clicking your ads? How to tell and what to do
Think a competitor is clicking your Google Ads? How to tell competitor clicks apart from other causes, what Google covers and the concrete steps to take.
Almost every local business owner who runs search ads has thought it at least once: “my competitor is clicking my ads.” The budget is gone by mid-morning, clicks keep coming in, yet the phone stays silent and no forms arrive. The suspicion is not unreasonable; competitor clicking is real. But not every wasted click comes from a rival. In this article we look, in measured terms, at how to separate competitor clicks from other likely causes, what Google already does about them, and which concrete options you actually have.
The short answer: you cannot diagnose a competitor from a single click, only from a pattern. And even once you have a diagnosis, the most effective step is rarely “block the IP”. It is usually fixing your signals and reducing your exposure.
Why do competitors click ads?
The motive is usually simple: someone bidding on the same keywords wants your budget to run out early so you drop out of the auction. Once your daily budget is spent, your ad stops showing for the day and the rival can buy the same clicks with less competition. That is why competitor clicking is most common in narrow geographies and in sectors where only a handful of advertisers compete: movers, locksmiths, boiler repair, clinics, law firms, towing services.
A second motive is curiosity and monitoring. Employees, agencies or the owner clicking a rival's ads to see what they offer look harmless, but they spend the budget just the same. The third group hires bots or cheap click services; here the pattern looks less like human behaviour and more like bot traffic.
Signs that point to competitor clicks
None of the following is proof on its own. When several appear at once and keep repeating, take them seriously.
Timing
Competitor clicks tend to follow office hours: they cluster at opening time, around lunch or shortly before closing, and almost never appear at night or on weekends. Genuine customer searches usually follow a more spread-out curve, depending on your sector.
Geographic proximity
If a striking share of clicks comes from the neighbourhood right next to your business, or from where a rival is known to be based, that is a signal. Be careful, though: mobile carriers resolve location only roughly, so proximity alone means little.
Same device, different IPs
Classic competitor clicking comes from the same device again and again. On mobile networks the IP address changes frequently and many users share a single IP (CGNAT). An IP-based view therefore either misses the competitor or catches innocent users. A more reliable trace is the device fingerprint and behaviour: the same screen resolution, browser version, language setting and similar session behaviour.
Zero engagement
A competitor clicks to drain your budget, not to spend time on your site. The typical trace: lands on the page, leaves within seconds, does not scroll, never touches the phone number or the form. Real users bounce too; the difference is the same device coming back.
Focus on specific keywords
Competitors usually search the most expensive, most commercial keyword in the sector. If, in the search terms report, an expensive term's share of clicks rises while its share of conversions stays flat, watch that term more closely.
| Signal | Competitor likelihood | Other possible cause |
|---|---|---|
| Clicks squeezed into office hours | Medium | In B2B, real customers also search during work hours |
| Repeated clicks from the same device | High | An undecided customer comparing offers |
| Concentration from a nearby district | Medium | Genuine local demand |
| Exit within seconds | Low–medium | Slow page, irrelevant search term |
| Data-centre ASN | Low (more likely a bot) | Corporate VPN, automation tool |
Rule out your own setup first
Before blaming a rival, check three things: are there irrelevant queries in the search terms report, is the location option set to include people “interested in” your area, and is the landing page slow on mobile? In most accounts, fixing these three removes a large part of what looked like competitor clicking.
Does Google cover competitor clicks?
Yes. Google's definition of invalid clicks explicitly includes manual clicks intended to increase an advertiser's costs, so a rival's deliberate clicking is invalid under the policy. Google filters a significant part of such clicks automatically before billing and credits some of them later. We explain how this works in our guide to invalid clicks in Google Ads.
The catch: Google judges whether a click is deliberate using only the signals it can see. A competitor clicking once or twice a day from an ordinary phone at an ordinary pace may be indistinguishable from a curious user. For the part Google misses, you can file a refund request, but it only works with click-level evidence.
What you can do, in order of impact
- Collect evidence: add click-level logging to your site (time, gclid, device characteristics, session behaviour). Google will not give you the clicker's IP or device; you can only collect this on your own site.
- Confirm the pattern: look at how often the same device returns, at what times, and whether it ever converts.
- Reduce exposure: lower bids in suspicious time slots with ad scheduling, tighten location targeting to “presence”, narrow the match type on your most expensive term.
- Exclude: add clicks that consistently come from the same static IP to your IP exclusion list. Use this carefully on mobile and shared IPs.
- Fix your signals: keep visits you consider invalid out of your conversion and audience signals so your bidding strategy does not learn to spend more on that traffic.
- Request a refund: file a review request with evidence for clicks Google did not remove automatically.
Why IP blocking alone is not enough
Google Ads lets you exclude up to 500 IP addresses per campaign. If your competitor clicks from a fixed home broadband line, that may suffice. If they click over mobile data, the IP can change with every connection and hundreds of innocent users may share the same address. Block such an IP and you lose potential customers, not the competitor. IPv6 and VPNs complicate the picture further. Use IP exclusion as a last step, only for static, repeating addresses.
Do not take matters into your own hands
Clicking a competitor's ads in retaliation violates Google's policies and puts your own account at risk. If your evidence is strong, report it to Google; if the damage is serious and ongoing, talk to a lawyer. Retaliatory clicking solves nothing, it simply burns two budgets.
What to keep in mind when collecting evidence
The only way to turn a suspicion into something concrete is to record what happens after the click. Mind three things. First, duration: a single day of data is misleading, so look at a window of at least two to three weeks. Competitor clicking repeats like a habit; a random spike does not. Second, comparison: compare click behaviour in suspicious hours with other hours, and suspicious devices with other devices. If there is no difference, the problem is not a competitor. Third, privacy: collect visitor data only for security and ad verification purposes, say so in your privacy notice and do not keep it longer than necessary.
Leave a trail on the Google Ads side as well. Export the search terms report and the hour-of-day performance report, and note click volume, average CPC and conversion rate for the suspicious period. Seeing in auction insights that a particular rival's impression share shifts in the same hours as yours is not proof on its own, but it completes the picture.
Priorities for small local businesses
If you are a local business with a limited daily budget, every click weighs a lot. The order of priorities shifts slightly:
- Review your ad schedule first: showing ads in hours when nobody can answer the phone wastes real demand and leaves an open window for deliberate clicks.
- Spread the budget across the day: running out of budget in the first morning hours is exactly the scenario where competitor clicking hurts most.
- Track your few most expensive keywords in a separate ad group; suspicious patterns usually show up there first.
- Make sure your conversion tracking covers phone calls and WhatsApp messages; otherwise you may mistake real customers for fake traffic.
These steps will not stop competitor clicking on their own, but they limit the loss and make the real problem visible. We describe our protection approach for small businesses on the small business solutions page.
One more practical note: when you suspect competitor clicks, pausing the campaign entirely can be tempting. But that hands real customers to the rival and resets the learning of automated bid strategies. Narrowing exposure and collecting evidence is usually cheaper than switching off.
Competitor or not? A decision guide
- Most clicks come from the same few devices and never convert → competitor or deliberate clicking is likely.
- Clicks come from data-centre networks at non-human speed → most likely a bot; the competitor may have hired one, but the fix is the same.
- Clicks come from different devices with irrelevant search terms → a match type and negative keyword problem.
- Clicks come from outside the target area → a location setting problem.
- Clicks are real but show no on-page engagement → a landing page or offer problem.
How wall.click approaches competitor clicks
wall.click scores every ad visit at session level through a lightweight script on your site: behaviour score, device fingerprint, ASN and data-centre detection, repeat-visit pattern. It can notice the same device returning with different IPs without relying on the IP. If the source is a static IP, it is added to your Google Ads exclusion list; if the address is shared or changing, no exclusion slot is spent on it and the visit is fed back to Google as a conversion and audience signal instead. Details are on our competitor fraud solution page.
An important caveat: no tool brings competitor clicking down to zero. The goal is to make the loss measurable, stop the repeating source and give Google clean evidence for a refund request. Those three goals move a competitor suspicion from a guess to something you can measure.
Frequently asked questions
Can I get my competitor's IP address from Google?
No. Google does not share the IP addresses of users who click your ads. You can only collect this data on your own site, in line with privacy law.
Will my account be penalised because of competitor clicks?
No. Invalid clicks are handled in the advertiser's favour: Google does not charge for those it detects, or credits them back. The risk is not account suspension but wasted budget.
My competitor clicks once or twice a day. Does that matter?
It does if your CPC is high and your daily budget is small. A few clicks can consume a meaningful part of the day in a low-budget local campaign. If the pattern persists, it is worth collecting evidence.
I have identified my competitor. How do I report it to Google?
Use the invalid click review form in the Google Ads Help Center. Send the click-level data you observed (time, gclid, device and behaviour), not the competitor's name. Google decides whether a click was invalid, not who made it.
Is it a problem if I click my own ad to check it?
Clicking your own ad to see it also creates spend. Use the Ad Preview and Diagnosis tool in Google Ads instead; it shows whether your ad appears without generating an impression or a click.
