I'm promoting eBay products via feeds of relevant products displayed on my sites.
What disturbs me is that I generated sales for them and got rewarded by 0.1% of sales revenue.
I think that this is due to their delayed-action quality score kicking in, I hope so!
For example: winning bid revenue of $120 and my share of this is $0.13
p.s. it's in the automotive niche.
