A click in the morning, another at night
A competitor “checks” your ads several times a day. You pay for every click and the budget runs out early.
You pay for every fake click.
Competitors, bots and the curious burn your budget before a real customer sees your ad. Blocking IPs alone is not enough: a phone gets a new address every time it switches network.
A phone changes address in seconds
Switching from Wi-Fi to mobile data is enough. An IP block will not stop the clicker – recognising the device will.
Clicks without customers
Anonymisers, proxies and data centres never call you. Nullklik recognises them on the first click.
How it works
Three steps. We never change your campaigns, budgets or ads – we only add exclusions.
Sign up your company
Enter your Google Ads Customer ID and accept the link with our manager account. We only see what the protection needs.
Add 1 line to GTM
A short code in Google Tag Manager. No plugin, your website loads exactly as before.
Nullklik blocks every hour
It verifies paid clicks directly in Google Ads and excludes suspicious IPs at account level – new campaigns included.
Blocks the clicker, not the customer
The rules follow how competitors really behave. Whoever calls is a customer. Whoever keeps clicking is out.
Device blacklist
A known clicker is blocked after their first paid click, even from a new IP address or another network.
Real customers protected
Clicks followed by a phone call from the same device are a customer, not fraud. Shared mobile carrier IPs are blocked for 24 hours only.
VPN and proxy detection
Anonymisers and data centres are recognised immediately. A foreign IP on its own is never a reason to block.
Account-level exclusions
Blocks apply to all campaigns, including new ones. Nothing to set up per campaign.
Paid clicks only
Every click is verified directly in Google Ads. Spoofed data cannot block anyone.
Dashboard and manual control
See who was blocked and why. Put your office on the whitelist, block a clicker manually.

Frequently asked questions
Will Nullklik slow down my website?
No. The code loads asynchronously and your website renders as fast as before. If Nullklik were ever down, your website and ads keep working.
Will I block my customers?
The rules count only paid clicks from one device. Anyone who calls after clicking is treated as a customer. Blocks on shared mobile IPs last 24 hours only.
How fast is a clicker blocked?
The device is flagged immediately. The IP exclusion is written to Google Ads at the next hourly sync.
What do you need from my Google Ads account?
Your Customer ID and accepting the link with our manager account. We never change campaigns, budgets or ads – we only add IP and audience exclusions.
What happens when I cancel?
Protection stops and at the next sync we remove all our exclusions. Nothing is left in your account.
What about GDPR?
Nullklik processes technical click data (IP address, click ID, an anonymous browser ID) only to protect against fraud. Data is stored in the EU (Germany) and events are deleted after 30 days. We sign a data processing agreement with every client.
