How affiliate program runs on WordPress

The same recipe everywhere. Here is the path a referral takes through WordPress.

A partner refers

They share a tracking link, or an assigned coupon code on Essentials.

A customer buys

The sale completes natively on your WordPress site, with no redirect and no middleman.

Siren attributes it

Last-touch by link or code. The right affiliate is credited the moment the order completes.

Commission is paid

As store credit, or real money via Stripe Connect on Plus.

Where it runs

On the site you own

Give affiliates a tracking link on Lite, assign a coupon on Essentials, or credit a referral by hand. Every matching sale is attributed automatically.

Payouts

Pay as store credit on Lite and Essentials, or real money via Stripe Connect on Plus.

Affiliate program on WordPress questions answered

Is there a free WordPress affiliate plugin?

Yes. The Basic Affiliate Program recipe runs on Siren Lite, which is free: unlimited programs and partners, link and manual tracking, and flat or percentage commissions. Upgrade later for coupons, renewals, automatic payouts, and team features.

How are affiliates attributed on WordPress?

By tracking link, cookie-based and last-touch, or by an assigned coupon code on Essentials. You can also credit a referral manually from the admin.

Can affiliates use coupon codes instead of links?

Yes, on the Essentials tier. Assign a coupon to a collaborator and every checkout that uses it is credited to them. This is useful for influencers who would rather share a code.

Does it work with any WordPress store or just WooCommerce?

Siren tracks WooCommerce and Easy Digital Downloads natively, plus LifterLMS and LearnDash course sales and Gravity Forms leads. Any sale your WordPress site records, Siren can attribute and reward.

How do affiliates get paid?

As store credit on Lite and Essentials, or as real money through Stripe Connect on the Plus tier. Partners self-onboard and are paid automatically.
