I still don't get it how Tube sites
 

Considering the cost of bandwidth, how are tube sites making money?
I bought some test traffic and redirected to AFF and conversion was really poor.

The tube surfers have seen AFF 90000000 times before you showed it to them

Here is a suggestion.
Buy micho niche domains then run some tube scripts and only add those niches, then link them all together and let google do it's magic. Sure it's not INSTANT cash, but lets face it. Use hosted clips. There is a ton of sponsors that offer 3minutes+ for FLV hosted now. Some do 6 minutes. Don't use your own bandwidth, let the sponsors worry about that.

Domain: $7
Script: $50 (sometimes lower - even free)
Shared server: $20

If you made just 2 sales per YEAR, you would make your money back.

Promote the programs that give you the videos - Paysites.

Hope that helps.

This can be done for sure.

You can also add some trade script to them if you want to go that route.

Cornering in 1 micro-niche is what I would recommend though.

Just the way I'm making some cash in some micro-niches...
My tubes are really good ranked on google!

so far everytime I contacted a tube site that was for sale, some getting over a million hits daily, their revenue was pathetic, all types of designs all types of traffic, but no cash, im no tube expert, but my guess is its not easy to make money off it.

but tubes are great if you get high seeing good alexa rankings, if you like showing off nice traffic stats.
