You're making an awful lot of assumptions but since this is HN and not a gay webmaster forum, I'll bite.
you can get .05 a click, but it won't matter if that particular keyword converts at 1:200.
Just because it converts at 1:200 for you doesn't mean that that's the rate for someone else. 90% of marketers can't make dating work on facebook, but the rest of the 10% make a killing. If you take their average CR, it'll be something atrocious (not as bad as 1:200, but bad nonetheless), but it makes no difference for those 10% of marketers. My point is that industry averages don't mean anything. It comes down to how good a marketer you are.
I know the mechanics of the industry...nothing can actually convert at 1:10.
Then we are in different industries.
ESPECIALLY if you do ppv and media buys like you say.
80% of my traffic generation is via media buys, 18%-19% via ppc and 1%-2% via ppv.
Hell...most products don't have 1:10 conversions for the actual order form.
Again, this comes down to the marketer. If that's all you can pull in with your landing page and copy, then that's all you can pull.
So you are going to tell me your colleagues are converting at 1:5 for an ebook product? How about 1:1?
1:1? No. 1:5? Yes. But they care more about the CPC and EPC than the CR.
the only way you can actually get 1:10 conversion rates...is if you do VERY targeted CPC...which usually means you are getting low volume(which explains the 40 cents CPC).
Of course I laser target my CPC, only a newb marketer wouldn't. But while low volume = low CPC, the inverse isn't necessarily true. It comes down to the marketer - a newb will pay $5 CPCs but an experienced one can get high volume traffic at a 10th of that price.
How many actual sales do you have every month at that 1:10 conversion rate?
Here are my numbers for July (rounded from memory) -
price of ebook - $8
visitors - 71,000
CPC - $0.40
expense - $28,400
CR - 10.9%
buyers - 7700
revenue - $62,000
EPC - $0.87
My advice is still the same - try not blanket everyone in a niche with your experiences or the avg #s for that niche. There's a reason why 90% of marketers barely make any profit and see dismal CRs and EPCs. It's because the rest of the 10% take everything (ever hear of 'Truth About Six Pack Abs'? that ebook's author used to net over $500,000 a day while the majority of the marketers in the health/exercise niche were barely breaking even.)
