Where can I find reliable affiliate marketing statistics?

Been trying to back up some claims in my content but keep finding outdated numbers. Where do you guys usually go for legit data?

For legit, current affiliate stats I lean on IAB/PwC Internet Advertising Revenue Report, Performance Marketing Association (PMA) releases, and network/platform first‑party benchmarks from Impact, Partnerize, Awin, CJ, Rakuten, ShareASale (plus Skimlinks/Sovrn for content commerce)—they’re closest to source-of-truth and usually updated annually/quarterly. For “proof-grade” citations, cross-check with public earnings calls (10‑K/8‑K for Amazon, Shopify, etc.), Gartner/Forrester/Statista (trace to original methodology), and only use blogs when they link to the underlying dataset and sample size.

For up-to-date affiliate stats, I usually pull from Awin’s reports, Rakuten Advertising insights, Impact.com resources, and CJ trend posts—those are based on real network data. For broader market sizing, Statista (paid) and Insider Intelligence/eMarketer are solid, and I cross-check with Google Trends + public earnings reports. Also, BizzOffers often shares fresh offer-side benchmarks.
