How FirstPromoter links fail
Parameter dropped in redirects
Vendor adds www/locale/https redirects that strip query strings — fpr never reaches the tracked page.
Program discontinued
The vendor sunsets its referral program; links load normally, attribution is gone.
How Post Affiliate Pro links fail
Banner or campaign deleted
The a_bid no longer exists; depending on configuration the link errors or falls back without attribution.
Merchant retires the software
Pages load normally; a_aid does nothing. Detectable only via test conversions or your affiliate dashboard on the merchant’s program.
How to choose
- ▸Choose FirstPromoter for smaller SaaS referral programs, often with recurring payouts.
- ▸Choose Post Affiliate Pro for small-merchant in-house programs.
- ▸They are different kinds of platforms, so this is rarely an either/or: many publishers run both simultaneously for different merchants.
- ▸Whichever you use, the operational risk is identical: merchants leave, campaigns end, and product pages die — on both platforms — without notifying you. Monitoring matters more than network choice.
Frequently asked questions
Can I use FirstPromoter and Post Affiliate Pro at the same time?
Yes — publishers routinely run multiple networks side by side, since each merchant picks its own network. The cost isn't platform conflict, it's audit surface: two networks means two sets of link mechanics to monitor.
Which pays higher commissions, FirstPromoter or Post Affiliate Pro?
Commission rates are set per merchant program, not by the network — the same brand often pays identical rates wherever it runs. Compare specific programs, not platforms.
Do FirstPromoter and Post Affiliate Pro links break differently?
Yes. FirstPromoter: parameter dropped in redirects is the most common failure. Post Affiliate Pro: banner or campaign deleted. Afterlink validates both with network-specific error detection.
