# What is click fraud

Click fraud is any click on your ads from someone with no interest in what you sell: bots, competitors, click farms or the same visitor again and again. You pay for each of those clicks, so it drains your budget and skews the data your campaigns learn from.

Every time someone clicks one of your ads, you pay for that click. Click fraud is when those clicks come from people, or programs, that were never going to buy from you. The click is real, the charge is real, but the visitor is not a customer.

## Where fraudulent clicks come from

-   **Bots and automated scripts** that load pages and click ads, often from data centers, to inflate traffic or test stolen ad setups.
-   **Competitors** who click your ads to drain your daily budget so their own ads show more often.
-   **Click farms**, where people are paid to click ads by hand, which makes the traffic look human.
-   **Low-quality placements** on websites and apps where ads sit next to buttons, so visitors click them by accident or are pushed into clicking.
-   **Repeat visitors** who click the same ad again and again, sometimes behind a VPN or proxy to hide that it is the same person.

## What it costs you

The obvious cost is wasted budget: money spent on clicks that cannot turn into sales. The hidden cost is worse. Ad platforms learn from your traffic, so fake clicks teach their bidding to chase more of the same. Your reports fill with visits that never convert, conversion rates drop, and it becomes harder to tell which campaigns really work.

Ad platforms already filter some invalid clicks and refund them. That filtering is not complete, and it only looks at the click, not at what the visitor does on your website afterwards.

## Signs your ads are being targeted

-   A spike in clicks with no matching rise in leads or sales.
-   Visits that last a second or two, or never scroll or interact with the page.
-   Many clicks from the same IP address, IP range, device or network in a short time.
-   Traffic from countries or placements you do not target, or from data centers, VPNs and proxies.
-   Your daily budget running out early in the day.

## How ClickGuard protects you

ClickGuard checks every paid click as it arrives. It combines what it learns about the click (the IP address, network, device and placement) with what the visitor does on your website, then scores how likely the visit is to be invalid. When a source keeps sending bad clicks, ClickGuard excludes it in your ad accounts, so it stops seeing and clicking your ads.
