How to run an affiliate program on WordPress

Decide who can join, which products qualify, how much commission you will pay, whether commission is a percentage or fixed amount, how long referrals remain eligible, and when commissions become payable. Exclude refunds, cancelled orders, taxes, shipping, and the affiliate’s own purchases if those should not earn commission.

Write the rules before inviting anyone. Include prohibited promotion methods, such as bidding on your brand name, spam, misleading claims, or unapproved discount sites. Tell affiliates that paid commissions may be reversed when an order is refunded.

For a small programme with only a few trusted partners, the manual route can work. Give each partner a unique coupon code, record the code, order number, customer, commission, refund status, and payout date in a spreadsheet, then review orders yourself before paying. This avoids cookie tracking, but it does not give you reliable click data, self-service affiliate accounts, automatic attribution, or scalable payouts.

For more than a handful of affiliates, use a plugin that connects to your checkout. Affiliate tracking normally depends on a referral parameter and a browser cookie, so privacy tools, blocked scripts, caching, and changed URL parameters can stop attribution.

Install a reputable affiliate plugin and enable its integration with your ecommerce system. Create or confirm the affiliate area, allow applications or add affiliates yourself, and set the default commission rate. Choose a referral cookie period that matches your sales cycle rather than copying a default blindly.

Enable coupon attribution as a backup for sales where the customer clicks on one device and buys on another. Check that the referral parameter used in new links matches the current setting; changing it later can make old affiliate links stop working.

Give each approved affiliate their personal referral link and, where useful, a unique coupon code. Provide approved product URLs, image sizes, suggested wording, brand rules, and a short disclosure such as “I may earn a commission from purchases made through this link.” The disclosure should be close to the recommendation or link, not hidden on a separate legal page.

Keep the programme easy to promote. A dashboard where affiliates can retrieve links and view referrals is preferable to sending links manually every time. Give affiliates a clear contact address for tracking questions.

Create a test affiliate and open its referral link in a private browser window. Confirm that the referral is recorded, the cookie or equivalent tracking value is set, the landing page works, and the affiliate is attached to the order after checkout. Test both a referral link and a coupon code, then test a refund or cancellation.

Also test with caching, cookie consent, security, and optimisation tools active. The common failure is seeing clicks but no commission because a script was removed, a query string was stripped, the cookie was blocked, or the order status does not qualify. Test again after changing domains, checkout pages, or consent settings.

Review pending referrals after your refund or dispute period. Reject self-referrals, refunded orders, duplicate orders, and traffic that breaks your programme rules. Keep a record of the order, commission amount, approval date, payout method, and any reversal.

If you want one system for referral tracking, affiliate management, fraud detection, commission rules, and payouts, AffiliateWP is a practical fast route. Its WooCommerce integration can create referral records from referred purchases, link coupons to affiliates, support product-specific rates, and let you reassign an order when attribution needs correcting.

Turn on self-referral protection before inviting affiliates, and use a holding period long enough to cover refunds. AffiliateWP documents self-referral checks, fraud flags, manual payouts, and scheduled payout options.
