Affiliate Networks Compared: Amazon, CJ, ShareASale, Impact

Amazon Associates, CJ Affiliate, ShareASale, and Impact are the four affiliate networks most independent publishers run into first. They are not interchangeable: each one connects you to a different mix of merchants, uses its own approval process, and reports commissions on its own dashboard. Picking the right one for a given piece of content matters more than picking a "best" network overall.

What does each network actually do?

An affiliate network sits between you (the publisher) and the merchant. Amazon Associates is a single-retailer program: you link to Amazon products and earn a share of what buyers spend during that visit. CJ Affiliate and ShareASale are network-of-merchants platforms: one account gives you access to thousands of individual advertiser programs, each with its own commission rate, cookie window, and approval rules. Impact (formerly Impact Radius) works similarly but is used heavily by SaaS, travel, and larger direct-to-consumer brands. Joining the network is step one; getting accepted into a specific merchant's program inside that network is a separate step.

How does the approval process differ?

Amazon Associates approves most applicants quickly but requires your first qualifying sale within 180 days or the account closes. CJ Affiliate and ShareASale let you join the network itself almost instantly, then you apply to individual merchant programs one by one, and each merchant can accept, reject, or ask questions before approving you. Impact's merchant programs tend to review applications more closely, often checking traffic and content quality before approval. If you are just starting out, a network with many merchant programs (CJ Affiliate, ShareASale) gives you more chances to get an early yes while you build a track record.

How do commission structures and cookie windows compare?

There is no single answer here because commissions and cookie duration are set by the individual merchant, not the network itself. Amazon's cookie window is notably short (24 hours for most purchases, longer only if the item is added to the cart during that visit), which rewards content that drives an immediate purchase decision. On CJ Affiliate, ShareASale, and Impact, cookie windows are set per merchant and commonly range from 30 to 90 days, which favors content aimed at considered purchases. Before joining any specific program, check its own terms page inside the network dashboard rather than assuming a network-wide rate.

Which network fits which kind of content?

• Amazon Associates: best when you review or compare specific physical products your readers are ready to buy soon.
• ShareASale: strong for small and mid-size e-commerce brands, software, and niche retailers; good for publishers who want a wide catalog to browse.
• CJ Affiliate: strong for larger, recognizable brands across retail, finance, and travel; useful once your site has enough traffic history to get accepted.
• Impact: strong for SaaS, subscription, and travel offers; often has more flexible or custom commission structures but a stricter application process.

What should you check before joining a network?

Read the network's and the merchant's terms for payment threshold (the minimum balance before you get paid), payment method, and reporting delay. Confirm how returns and cancellations affect already-approved commissions, since most networks claw back commissions on refunded orders. Check whether the network supports the tracking method your site needs, such as deep linking to specific product pages rather than just a homepage link. For a general framework on evaluating any program once you've narrowed your options, see Choosing Affiliate Programs.

Do you need to disclose which network you use?

No, but you do need to disclose that a link is an affiliate link regardless of which network pays you. The FTC's guidance on endorsements requires a clear and conspicuous disclosure placed near the link itself, not buried in a footer or an "about" page (https://www.ftc.gov/business-guidance/resources/disclosures-101-social-media-influencers). The network you use does not change this obligation. See Affiliate Link Disclosure for how to write and place that disclosure correctly.

Can you join more than one network at once?

Yes, and most established publishers do. Running Amazon Associates alongside ShareASale or CJ Affiliate lets you cover both quick-purchase product reviews and higher-commission considered purchases from the same site. The tradeoff is more dashboards to check and more terms to keep track of. If you are just starting out, joining one network of merchants (ShareASale or CJ Affiliate) plus Amazon Associates covers most publisher needs without spreading your attention too thin. Once you are running multiple programs, Maximizing Affiliate Earnings covers how to place and balance links across them without hurting the reader experience.

Decision checklist

Question	Amazon Associates	CJ Affiliate / ShareASale	Impact
Fast approval?	Yes, network-wide	Join network fast, per-merchant review varies	Per-merchant review, often stricter

Conclusion

No single affiliate network is objectively best. Amazon Associates rewards content tied to an immediate purchase; CJ Affiliate, ShareASale, and Impact reward patience and a wider catalog of merchant programs with longer cookie windows. Match the network to the kind of buying decision your content supports, read each merchant's own terms before you link to it, and disclose the relationship regardless of which network is paying you.
