Cookie Settings

Cookies store referral information on visitors' browsers, enabling attribution when they return to purchase. Configure cookie settings to balance tracking accuracy with user privacy.

Cookie duration determines how long after clicking an affiliate link a sale can be attributed:

• 7 days — Short window, impulse purchases
• 30 days — Industry standard for most products
• 60-90 days — Higher-consideration purchases
• 365 days — Long sales cycles, B2B products

First-Party Cookies (Recommended)

Set on your domain (yourstore.com). Not blocked by Safari ITP, Firefox ETP, or ad blockers. This is Spark!'s default and recommended setting.

Server-Side Tracking

Store referral data server-side instead of in browser cookies. Immune to all client-side blocking but requires customer identification (email or account).

When a visitor clicks multiple affiliate links, configure how cookies are handled:

• Always Overwrite — Last affiliate always wins (matches last-click attribution)
• Never Overwrite — First affiliate is locked in (matches first-click attribution)
• Append — Track all affiliates for multi-touch attribution

Spark! tracking is designed for privacy compliance:

• GDPR — Referral cookies are considered "strictly necessary" for affiliate payouts
• CCPA — No PII stored in cookies, only affiliate reference IDs
• Cookie Consent — First-party essential cookies typically don't require consent

For maximum privacy, enable cookie-less tracking alternatives:

• URL Parameters — Pass affiliate ID through the entire session
• Fingerprinting — Statistical device matching (optional)
• Email Matching — Match checkout email to click email
• Account Linking — Associate referral with customer account
