NATS with Netbilling.
Homegrown Video and our niche sites, hairy bush, big cock, big tits, milf, cream pie based on overall traffic, including type ins, google, etc.
1:529 for October, average of all traffic combined on all sites, affiliate and internal traffic.
One year ago we were at 1:2000 for the same period, less sites, but pretty similar overall traffic strategy.
Our new sites are tested on tube traffic primarily, so those ratios tend to skew the overall average since we haven't brought in the SEO, affiliates, review sites, trades, etc. that would bring the average way down and more similar to an established site like HGV.
