A story of Success
I've been really into SEO and interlinking my own network of sites to get high rankings in the SERPS for the past year, and experimenting with different types of linking strategies, automation of content creation, and building up decent revenue with AdSense and affiliate offer marketing through search engines and Social Media.
Well, my network included about 20 sites when this picture was taken, each making about 2-15 dollars a day. That was April. Now, I've obtained about 100 sites, all feeding link juice to each other on seperate IPs and hosting. This drives mad traffic and I currently make a few hundred dollars to nearly 1000 (peak traffic) a day from this small network.
I maybe spent $2000 on this tops, but you can start out with 10 dollars for a domain and cheap hosting. Once you start building your network, just gotta keep making it bigger with better links and what not. If you can pay for something to automate most of it, do it and you'll save a lot of time and make a ton more money.
I leverage the traffic with cheap search traffic, too, and run affiliate offers through landing pages which bring me at least a few thousand a day now, too. It took a while to set everything up and realize what I was doing, but I'm glad I sat down and just decided to do it rather than care about whether or not my accounting homework gets turned in on time instead. Now, my college mates are all asking me to teach them in class instead of the boring marketing teacher. Lol..
