What is click fraud protection software?

Click fraud protection software detects and prevents invalid clicks on your paid ads in real time. It scores every click on device, network and behavioural signals, identifies bots, click farms and competitor clicks, and automatically excludes the fraudulent sources — so your budget reaches real prospects.

The need is channel-dependent: invalid traffic ranges from 2.18% on search to 15.9% on native ads, and on a large budget even a low percentage is real money spent on clicks that can never convert.

How it works

How click fraud protection works

Protection happens on every click, in real time, before the fraud drains more budget:

1

Score each click

Device fingerprint, IP and network reputation, and behaviour are scored on every click as it happens.

2

Identify the fraud

Bots, click farms, competitor clicks and fraudulent publishers are separated from genuine prospects.

3

Exclude automatically

Invalid sources are added to exclusions across your campaigns, so they stop costing you.

4

Reallocate budget

Spend is freed up for real users, and your reporting reflects genuine performance.

What the best click fraud protection has

Look for

  • Published data and transparent methodology
  • Fast tag or firewall setup

Avoid

  • Single-platform-only tools
  • Reports without prevention
  • Blunt blocking that loses customers
  • Claims with no data behind them
  • Long, heavy integrations
