Affiliate tracking software built on first-party data
Track every referral, whether it comes through a link, a personal coupon code, or a server-side conversion, and credit the right partner even when several touch the same sale.
Third-party cookies are gone. Most affiliate trackers haven't noticed.
Affiliate software that leans on third-party cookies is quietly losing referrals every day, and the partners who earned them are the first to notice.
What is broken tracking actually costing you?
- Cookies are blocked by default. Safari and Firefox drop third-party cookies and Chrome is following, so cookie-based trackers lose referrals the moment a browser says no.
- Coupon sales go uncredited. Influencers and creators share codes, not links, and most trackers cannot tie a coupon used at checkout back to the partner who drove it.
- Partners stop trusting the numbers. When attribution silently misses sales, your best partners see the gap, lose faith, and take their audience elsewhere.
Capture every path to a sale
Every referral path is tracked the same way, and nothing depends on a third-party cookie surviving the browser.
- Referral links with first-party tracking, recorded against your own domain.
- Personal coupon codes tied to a partner and credited automatically at checkout, no link required.
- Server-side conversions posted straight from your server via API or webhook.
Choose how credit is shared
Real funnels are messy, and several people often touch a customer before they convert. Pick the model per program, and change it later without re-tracking.
- Last and first touch credit the most recent referrer, or the one who started it.
- Top score and weighted split reward the strongest contributor, or split by how much each one helped.
- Shared pool divides one reward evenly across everyone who touched the sale.
First-party and durable by design
Tracking runs first-party and server-side, so it survives ad blockers, Safari ITP, and the death of the third-party cookie. The same engine works across every channel you sell on, not just one WordPress site.
- Survives cookie loss with first-party, server-side records.
- Append-only audit trail, so every engagement is traceable at payout time.
- Multi-channel: one engine credits sales across every channel you run.

Affiliate tracking software, answered
How does Siren track referrals without third-party cookies?
Tracking is first-party and server-side. A click or coupon is recorded against your own domain and confirmed by a conversion posted from your server, so nothing depends on a third-party cookie surviving the browser.
Can it track sales made with a coupon code instead of a link?
Yes. Each collaborator can have a personal coupon code; when a shopper uses it at checkout, the sale is attributed to that partner automatically, with no referral link required.
Which attribution models are supported?
Five: last touch, first touch, top score, an evenly shared pool, and a performance-weighted split. You choose per program, and you can change it without re-tracking.
Does affiliate tracking work outside WordPress?
On the hosted edition, one Siren install tracks across every site and storefront you run, through a REST API and webhooks. The WordPress edition tracks everything on that site natively.
How accurate is tracking when shoppers use ad blockers?
Because conversions are confirmed server-side rather than by a client-side pixel, ad blockers and tracking-prevention features don't break attribution the way they do with cookie-based tools.
"I built Siren because I watched referrals go uncredited and partners walk away. Tracking that survives the modern web is the whole point."
Track what actually drives growth
Stop losing referrals to dead cookies. Credit the partners who earned it, and pay them with confidence.
