Network selection is the most consequential technology decision in affiliate program setup — it affects publisher access, tracking quality, reporting depth, and annual cost. Here's a structured comparison of the four networks most brands evaluate.
# Impact vs. Awin vs. CJ vs. ShareASale: Choosing the Right Affiliate Network in 2026
How to evaluate affiliate networks
Before comparing specific networks, establish your evaluation criteria: publisher access (does the network have the publishers you need?), tracking quality (server-side tracking availability, mobile tracking quality), reporting (publisher-level detail, API access), fraud protection (built-in fraud tools, investigation team quality), network fees (percentage charged on top of commissions), and client service (dedicated account management, onboarding support quality). Weight these criteria by your program's specific priorities — a brand focused on content publisher recruitment weights publisher access heavily; a brand with 90% mobile traffic weights tracking quality first.
Impact (formerly Impact Radius)
Best for: mid-market DTC brands, brands with sophisticated tracking requirements, programs wanting the strongest API and reporting infrastructure.
Publisher access: strong mid-market publisher network, particularly strong in US content publishers; somewhat weaker internationally than Awin.
Tracking: best-in-class server-side tracking (Impact's S2S implementation is the most developer-friendly in the market); strong mobile attribution.
Reporting: deepest reporting of any major network; API access is robust and well-documented; customizable dashboards.
Fraud: Forensiq integration is the strongest fraud detection stack in the market.
Fees: published tiered subscription pricing (starting at $30/month or 3% of platform-driven revenue, whichever is higher) plus a per-transaction network fee layered on top of commissions paid — confirm the exact current percentage directly with Impact.
Best fit: brands with >$500K annual affiliate GMV potential, technical team to leverage API, priority on reporting depth.
Awin (includes ShareASale)
Best for: international programs (UK/EU/AU), brands that need breadth of publisher types including coupon and cashback at scale, value-conscious programs.
Publisher access: largest publisher network globally; particularly dominant in UK/EU markets; strong coupon, cashback, and loyalty publisher depth; acquired ShareASale (US-focused, broader SMB publisher base).
Tracking: solid tracking including S2S option; historically slightly weaker mobile tracking than Impact, but has improved.
Reporting: good reporting; slightly less configurable than Impact; API access available.
Fraud: Publisher Quality Programme (PQP) is a proactive publisher quality scoring system; dedicated fraud investigation team.
Fees: monthly platform fee plus a 3.5% tracking fee on the value of each tracked transaction, on top of commissions paid to publishers.
Best fit: brands expanding internationally, brands needing coupon/cashback publisher depth, UK/EU market primary.
CJ (Commission Junction)
Best for: enterprise brands, retail brands with large SKU catalogs, brands valuing publisher relationships at the enterprise level.
Publisher access: oldest major network with deep enterprise publisher relationships, particularly strong with major media (CNET, Wirecutter-style comparison publishers, large coupon networks); strong retail publisher depth.
Tracking: solid tracking; S2S available; historically strong data feed infrastructure for retail brands with product catalog integration.
Reporting: enterprise-grade reporting with strong multi-touch attribution options; API access.
Fraud: CJ's fraud detection is mature (network has been operating since 1998); strong enterprise publisher vetting.
Fees: percentage fee structure varies; tends to be priced for enterprise volume.
Best fit: enterprise brands, retail/e-commerce brands with large catalogs, brands prioritizing access to enterprise comparison publishers.
ShareASale (now an Awin company)
Best for: SMB brands, programs just launching, brands with lower GMV potential needing accessible entry.
Publisher access: broad US-focused publisher base, historically strong with bloggers and niche content publishers; acquisition by Awin has expanded publisher access.
Tracking: functional but historically less sophisticated than Impact or CJ; S2S tracking added post-Awin integration.
Reporting: solid for SMB needs; less configurable than enterprise-tier networks.
Fees: lower minimum fees and transaction-based pricing that's more accessible for launching programs.
Best fit: brands under $250K annual GMV potential, budget-constrained launches, niche DTC brands testing affiliate before committing to enterprise network.
Decision framework
- ◆Annual GMV <$500K, US-only, budget priority → ShareASale
- ◆Annual GMV $500K–$5M, US-primary, technical sophistication → Impact
- ◆Annual GMV $1M+, international expansion in scope → Awin
- ◆Annual GMV $5M+, enterprise retail → CJ
If international expansion is in your 18-month roadmap, start on Awin even if your current GMV is below its typical threshold — migrating networks is expensive and disruptive.
