First, look at this formula:
[[DV x R x 365 x DO x AS]/2] - [DO x P] = REVENUE
where
DV = daily visitors on each site
R = average out signup ratio from the sites
365 = days per year
DO = number of domains you buy
P = price of domain
AS = average signup revenue
-------------------------------------------------
Example:
Lets say you gain 500 daily visitors (which can be achieved easily), 1 out of 10.000 of your visitors signup for a paysite, and your average revenue is $10 per paysite.
You buy 120 domains in one year, price $10 per domain.
Now, that is 1 domain every third day, so depending on how much routine you have and how structured you are (make some different standard templates etc.) you can build a static freesite with a decent amount of gallery links and paysite links.
Don't waste time on nice graphics with photoshop etc, because all you need is some different tables and some nice colors.
Your traffic should be a mix of SE, fewer trades and your own sites, so it is quite obvious that every trade you have will not link all your sites. So vary it, and also vary your links to your own sites to avoid beeing punished by the search engines. Just find the best way to achieve your 500 visitors (or more, depending on your goal.)
The dividing by 2 is made to follow a normal statistic distribution, assuming you create one new site every third day throughout the year. At the second year you can remove the divide and your revenue will be doubled.
RESULT: With these variables you almost earned $10k in one year, and if you play with the numbers you can earn even more... alot more!
NOTE: You can use freehosts to keep the costs down to a minimum, but its much easier to manage if you use your own dedicated server(s).
---------------------------------------------
The only limit is time, creative thinking, and most important; understanding of the equation;
- One variable can affect the other if you strobe for and waste time on unrealistic goals. Skimming is a good example; You might get higher traffic, yes, but the ratios fall. Instead, spend time on new websites and optimize your net revenue....unless you care more about toplists than money
Good luck
