Affiliate Link Management: Tracking, Hygiene, and Fraud Prevention
Broken links lose commissions. Untracked links enable fraud. Most affiliate programs treat link management as an afterthought — here's why it's a strategic function.
Link Structure Best Practices
Every affiliate link should include at minimum: (1) A unique publisher identifier (sub-ID or affiliate ID) that identifies who sent the click; (2) A campaign identifier if you run multiple campaigns or creative variants; (3) Sub-IDs for content placement (homepage vs. sidebar vs. in-content) to diagnose where conversions come from. On Impact: use tracking link parameters. On CJ: use PID and SID. On a custom platform: encode a structured token. Avoid shortened links in affiliate tracking — they add an extra redirect that can break on mobile and mask the destination from compliance monitoring tools.
Link Hygiene Audits
Conduct a link audit quarterly: (1) Check all publisher-placed links for accuracy — publisher websites change structure, and embedded affiliate links can break silently; (2) Verify redirect chain integrity — a link that redirects through 4+ hops risks click loss and cookie drop; (3) Confirm deep links are still valid — product pages get removed, SKUs get discontinued; (4) Review parameter accuracy — publishers sometimes strip tracking parameters when copying links, breaking attribution. Most networks have a 'link health' report; pull it before every QBR.
Deep Linking Strategy
Deep links — affiliate links that land users on a specific product or category page rather than the homepage — convert at 2-3x the rate of homepage-landing links. Use deep links for: product reviews (link to the exact product reviewed), comparison content (link to the specific SKU compared), seasonal campaigns (link to holiday collection or sale page). Most networks support deep linking natively. Enable it by default for all publishers and include deep link examples in your publisher onboarding materials.
Link Fraud Indicators
Monitor these link patterns for fraud signals: (1) High CTR, low CVR — normal affiliate CTR-to-CVR ratio is 0.5-2%; ratios below 0.1% suggest click stuffing or forced clicks; (2) Geographic mismatch — if your brand sells only in the US and you're seeing clicks from Eastern Europe or Southeast Asia, investigate; (3) Identical session IDs across hundreds of conversions — indicates cookie stuffing; (4) Conversion spikes with no corresponding traffic increase — a publisher converting at unusually high rates with low traffic often indicates fraudulent self-conversion. Flag these to your network's fraud team immediately.
