Affiliate Link Testing Checklist
Use this workflow before launching spend. It helps you catch broken tracking logic while
budgets are still small.
If you buy traffic on networks like Google Ads, Meta, native, or push, your link path is part
of your conversion funnel. A fast landing page cannot save a campaign if redirects drop click IDs,
overwrite cookies, or route users to inconsistent destinations.
Why this checklist matters
1. It prevents silent attribution loss that makes profitable traffic look unprofitable.
2. It reveals slow redirect hops that increase bounce rate before users even see your landing page.
3. It gives your team a repeatable QA process before every campaign launch or offer switch.
Pre-launch checks
1. Confirm the destination URL opens with HTTPS and a valid TLS certificate.
2. Verify core params exist in the first click URL: click ID, sub ID, source, campaign.
3. Test links on desktop and mobile user agents to detect device-specific rerouting.
4. Verify final landing URL is exactly the expected page and not a fallback or default route.
Redirect and attribution checks
1. Trace every hop and flag any hop slower than 1000 ms.
2. Compare initial vs final query params and record missing values.
3. Check Set-Cookie behavior for attribution cookies and expiration windows.
4. Validate redirect status code intent: use permanent redirects only for stable canonical paths.
Common failure patterns
1. Tracker A passes subid, tracker B expects sub_id, causing attribution
mismatch.
2. Redirect middleware strips unknown query parameters for "security" and drops click IDs.
3. Geo-based route sends some users to an old endpoint where postback mapping is outdated.
4. Cookie is set with wrong domain or SameSite policy, so conversion page cannot read it.
Scale decision checks
1. Keep only paths that preserve all required tracking parameters.
2. Route paid traffic to the fastest variant with stable final landing behavior.
3. Re-test after each tracker, cloaker, or network setting change.
4. Save test traces with timestamp so you can compare "before" and "after" when results shift.
Recommended launch workflow
1. Build 3-5 tagged URLs for the same offer (desktop, mobile, geo variants).
2. Run each through the redirect tool and export results.
3. Approve only link paths that pass parameter integrity and latency thresholds.
4. Start with low budget and compare attributed conversions vs expected baseline.
5. Scale budget only after link behavior remains stable for 24-48 hours.
FAQ
How many test clicks should I run before launch?
Run at least 10-20 test clicks across desktop and mobile user agents. Include clean
clicks and parameterized clicks to validate tracking consistency.
What is the most common reason affiliate attribution breaks?
Parameter loss during redirects is the top issue, especially when intermediate systems
rewrite URLs or strip unknown query keys.
Should I test links from multiple geographies?
Yes. Geo-routing and CDN behavior can alter redirect paths and latency. Test from at
least two key target regions before scaling spend.
