AtomicFilter Overview
AtomicFilter is Atomicat's built-in traffic filtering system. It lets you create campaigns that intelligently route different visitors to different pages based on a set of rules — country, language, device type, VPN usage, bot detection, and more.
What is Traffic Filtering?
Traffic filtering (also called cloaking in digital marketing) means showing one page to specific visitors (e.g., your real offer) and a different page to others (e.g., a neutral "white page") — based on rules you define.
Common use cases:
- Showing a compliance-friendly white page to ad platform crawlers
- Blocking traffic from prohibited countries
- Filtering out bots and VPN users from your analytics
- Routing mobile vs desktop users to different pages
Key Concepts
| Term | Meaning |
|---|---|
| Campaign | A set of filtering rules tied to a website |

Filtering Options
AtomicFilter supports the following filters per campaign:
| Filter | Description |

How AtomicFilter Works
Visitor arrives at campaign URL
↓
AtomicFilter evaluates the visitor against your rules
↓
Passes all rules? → Offer Page (your main funnel)
Fails any rule? → White Page (neutral/compliance page)
This happens transparently and in milliseconds — the visitor is redirected before the page fully loads.
