You're throwing away ~12% of clicks at the border
The mistake: running US-only links while 8–15% of your traffic is non-US. Those readers hit a US product page, can't buy, bounce — and you earn $0.
With OneLink (Amazon's geo-redirect) the same click routes to the reader's local store and pays you in that program.
— Before OneLink: international clicks converting ≈ 0.4%, n=6,000
— After OneLink (UK/CA/DE enabled): same cohort ≈ 2.8%
That recovered roughly $0.06 EPC across all traffic, not just foreign.
Fix: enable OneLink in Associates settings, join UK/CA/DE programs, add the one-line script.
So what: a 15-minute setup converts dead foreign clicks into 7 paying storefronts.
