How to Choose Affiliate Tracking Software: A 10-Point Checklist
A buyer's checklist for affiliate tracking software: postback support, ad-platform integrations, click-ID capture, pricing model, data ownership and more — with the questions to ask before you pay.
Affiliate trackers look interchangeable in feature tables and very different in production. This checklist focuses on the things that actually decide whether your attribution survives contact with real traffic.
1. Server-to-server postbacks, not just pixels
Browser pixels are increasingly blocked. Your tracker must accept server-to-server postbacks from affiliate networks and let you map their parameters (SubIDs, payout, status) to your own fields.
2. Ad-platform conversion APIs
Can it send conversions back — Meta Conversions API, TikTok Events API, Google Ads conversion import? Receiving conversions is only half the job; feeding them to the ad algorithm is where the ROI comes from.
3. Click-ID capture that survives redirects
Ask exactly how the tool captures and stores gclid, fbclid and ttclid, and how those values are echoed into network SubIDs. If the answer is "the network handles it", your paid-traffic attribution has a hole.
4. SubID flexibility
Networks differ wildly — Impact's {SubId1}, PartnerStack's {custom_key}, and many custom schemes. You want configurable parameter mapping, not a fixed template.
5. Redirect behavior and ad-network compliance
If you run Google Ads, the tracker's redirect must be transparent: a single server-side 302, same destination for everyone, no cloaking. Ask whether the vendor is familiar with Google's Certified Click Tracker requirements.
6. Test tooling
A "send test conversion" button and visible request/response logs save days of debugging. If you can't see exactly what the tracker sent to Meta or Google, you'll be blind when something breaks.
7. Reporting granularity
You need per-click drill-down: which SubID, which campaign, what payout, which platform it was forwarded to, and whether the dispatch succeeded. Aggregate-only dashboards hide the exact rows you need when reconciling with a network.
8. Pricing model
Trackers price by clicks, events, conversions or revenue. Model your own volume: a cheap plan with a low event cap can cost more than a flat plan once a campaign scales. Check what happens when you exceed the quota — hard cutoff or overage?
9. Data ownership and export
Your click and conversion data is your business memory. Make sure you can export it, and that retention isn't silently capped on lower tiers.
10. Security and access control
Postback tokens, API keys and pixel credentials should be stored server-side, never exposed in the UI after saving. Role-based access matters the moment a second person touches the account.
