great guide lilrich... it's the way I do it... it's not as easy as written... I've had problems getting over certain thresholds...
You have to have a certain production % to support # of trades... and certain payback % to keep those trades alive... and a certain # of incoming traffic (bookmarkers, etc) to feed your trades...
my figures are about 20 trades for each 100% of prod you have... so if you have prod of 150% you want a max of 30 trades because the bottom ones will not get enough of the ass-end hits...
you want about 130% payback ratio... this is affected by the # of trades you have, your incoming feeder traffic, and your production...
There's probably a mathematical equation for this... and I'm sure someone has dedicated their time to figuring it out... but mine are just rough estimates from my experience... trial and error of adding too many trades at once and killing my whole fucking site!
but once you can get 2 or 3 sites at about 20-30k it makes it easier to get your new sites going...
