# Property

> Everything AnyTrack manages for one website (root domain) — its Tracking Tag install, integrations, pixels, settings, and reports. One Property per root domain; subdomains share it.

A **Property** is everything AnyTrack manages for one website: the [Tracking Tag](/glossary/tracking-tag) install for that domain, its [conversion source](/glossary/conversion-source) integrations, its connected [Tracking Pixels](/glossary/tracking-pixel), its settings (including the attribution window), and its reports. Every event and conversion belongs to exactly one Property, and the [Property ID](/glossary/property-id) prefixes every Click ID it generates.

## Property scope: one root domain

Use **one Property per website (root domain)** — never per page. Subdomains (`www.`, `shop.`) share the first-party cookie and belong in the **same** Property, with the same Tag on every page. A genuinely separate domain is its own Property; connect the two with [cross-domain tracking](/glossary/cross-domain-tracking) (the recommended setup for two-domain funnels — do not consolidate two real domains into one Property).

## Property topology gotchas

- **The pixel-less Property dead end:** a Property that records purchases but has **0 pixels** connected sends nothing to any ad platform. Common shape: ads land on the main site (Property A, pixels connected) while the checkout runs on a hosted cart or booking domain tracked as Property B with no pixel. The fix is cross-domain tracking from Property A — never connecting the ad platform to Property B, which the ad click never touched.
- **Attribution settings live per Property** — the attribution window (1, 7, 30 days, or maximum) is set in Property Settings.
