If you need google traffic (since you have ruled out Katz) start ranking for sum keywords. First, use google adwords or sum good keyword tool. search for the general keyword you are targetting. example : porn, stockings, xxx, busty
Then you will get a keyword list with total number of searches made per month for specific keywords. The higher number ones are usually a lot competitive so start by targetting lower number ones like say within 5,000-20,000 searches per month.
Now that you have your keywords... start your campaign. You need to keep getting backlinks daily as many as you can, till your site ranks within 1-3 for the keyword you are targetting.
Say you manage to get your site ranked within 1-3 for a certain keyword. That keyword(s) has 20,000 searches per month. then calculate like this : 75% x 20,000 = 15,000 visitors per month. I have used 75% because usually Google 1-3 receives 75% hits from the total no. of searches... while 4-10 receives 25% hits from the total number of searches.
So as long as you rank within 1-3 for that keyword, you will keep on receiving around 15,000 visitors per month from those searches. Once you dominated one keyword... find another process and repeat till you dominate another keyword.
Yes i know its tough, time consuming, etc... but its solid traffic this way.
