A method of sending conversion data directly between servers via HTTP requests, bypassing the user's browser entirely. More reliable and privacy-compliant than browser-based tracking.
Server-side tracking (also called S2S or server-to-server tracking) sends conversion events from one server to another using postback URLs. When a conversion happens, the advertiser's server fires an HTTP request to the tracker's server with the click ID and conversion details.
Unlike conversion pixels that rely on browser JavaScript, S2S tracking is immune to ad blockers, cookie restrictions, and browser privacy features like ITP (Intelligent Tracking Prevention).

1. User clicks link → GeoRedir assigns click_id=abc123 2. GeoRedir appends ?click_id=abc123 to destination URL 3. User converts on advertiser site 4. Advertiser server fires: GET postback_url?click_id=abc123&payout=25.00 5. GeoRedir records conversion linked to original click
The click ID is the key that ties everything together. It's passed through the redirect chain and returned in the postback when a conversion occurs.
GeoRedir supports server-side tracking natively. Enable conversion tracking on any smart link, and GeoRedir automatically appends a unique click_id to the destination URL. Configure your postback URL in the link settings, and conversions are recorded with revenue, payout, and source data. Full setup in the Conversion Tracking Guide.
GeoRedir's S2S tracking is immune to ad blockers and cookie restrictions. 95-100% accuracy.
