A program is one company paying you to promote their product — like Wealthy Affiliate paying commissions on referrals. A network is a middleman hosting hundreds of programs under one roof, like Impact, ShareASale, or Amazon Associates. Networks give you variety and one dashboard; direct programs often pay better rates and build closer relationships. Most successful affiliates end up using both.

Some yes, some no — and that difference matters more than beginners realize. Big retail networks often review your site and can decline you with automated filters before a human ever looks. But plenty of quality programs are open enrollment: you join, you get your links, you start promoting the same day. When you're starting out, open programs let you earn while you build the traffic that gets you approved everywhere else.

Start with one anchor program you know deeply, then build outward. Spreading across five programs on day one splits your focus and your content. The stronger play is proving one funnel works, then adding income sources that fit naturally — a recurring program here, a seasonal offer there. Multiple income streams is the goal; multiple half-built streams is the trap.

Rate alone is a rookie metric. A 50% commission on a product nobody buys earns less than 10% on something that converts all day. Look at the full picture: conversion rate, cookie length, recurring vs one-time payouts, and whether the product genuinely helps your audience. A fair rate on a great product with recurring billing beats a huge rate on junk every single time.
