I Analyzed 28,844 Affiliate Programs on Skimlinks. Here’s What Most Affiliates Get Wrong.
Two-thirds appear inactive or immaterial. The median EPC is $0.14. Commission rate is the wrong thing to optimize — EPC is. A full data breakdown of every program on the Skimlinks network.
Most Programs Are Dead Weight
Of 28,844 listed programs, 19,191 have no click data — no EPC, no conversion rate, no basket size — suggesting the program is inactive or immaterial on the Skimlinks network. Some may be new listings or programs primarily active on other networks, but even with generous assumptions, the actual pool is far smaller than the catalog.
The EPC Distribution Is Brutal
Of the 9,356 programs with a measurable EPC, the distribution is massively right-skewed. Two-thirds earn less than $0.25 per click. Most programs cluster between $0.01 and $0.25.
Commission Rate Is the Wrong Metric
Commission rate ignores basket size and conversion rate. EPC (earnings per click) = commission × basket × CVR. It captures the full picture in one number.

2. High commission × high CVR — Pets ($112 basket, 8.1%, 6.1% CVR), Food & Drink ($92, 9.5%, 5.5% CVR). Volume compensates.
The trap is the middle: verticals with moderate everything that look decent on paper but don’t stand out on any axis. Software & Technology has the highest commission rate of any vertical (31.6%) and the lowest EPC ($0.22) because almost nobody converts (2.1% CVR).

The 20 Highest-Earning Programs
Ranked by EPC. Note the pattern: high EPC almost always comes from massive baskets or unusually high conversion rates — rarely from commission rate alone.

Methodology
Dataset: 28,844 programs from the Skimlinks network. Of these, 9,653 had at least one non-zero performance metric → 9,356 had non-zero EPC → 9,323 could be classified into verticals. EPC/basket/CVR averages use non-zero values only. Reversal rates averaged across all programs in the vertical, including zeros.
Vertical classification used cross-network category matching against CJ, FlexOffers, Impact, Awin, and others, with Skimlinks categories and manual review as fallback. All 9,323 programs with non-zero EPC classified into 21 verticals.
“No click data” means no EPC, no commission rate, no basket size, and no conversion rate reported. Some of these may be new listings or programs primarily active on other networks. The absence of data does not confirm the program is permanently inactive, but it does mean there is no evidence of conversions on this network.
