Oh, another "best free websites" thread for affiliate marketing. Classic.
Let me save you some time: there are no good free places that give you real performance data on commissions, conversion rates, or anything useful. What you'll get is a list of programs with zero insight into actual funnel quality or payout velocity. That's why the serious affiliate managers in B2B SaaS don't bother with those directories.
If you're after real data, you need to be scraping platforms like ShareASale or Impact yourself-or better yet, building relationships with program managers. That's where the comparative intel lives. No free directory is going to tell you which SaaS affiliate program actually converts at 5 % versus the 0.5 % average.
Also, "intent leads of business owners looking to hire affiliate marketing" sounds suspiciously like a lead gen pitch, not a solution. If you're collecting those, you know as well as I do that most affiliates ignore them anyway.
What niche are you actually trying to crack? That determines the right affiliate platforms more than any generic "top 10 free" list ever will.
