Paul Gilchrist is a web site publisher and search engine optimization specialist.
I have had good success with using Google's Adsense program. I am looking for people who have web sites who may want to leverage the traffic that they have into dollars. So, if you have lots of visitors to your site, but don't know how to optimize or use Adsense to get them clicking on ads and providing you with a solid cash flow, please contact me. We can do a joint venture or you can just pay me if you prefer to retain complete control.
I also do Search Engine Optimization, so I can beef up the traffic that you are getting.
Some of my sites are found on the Links page.
If you don't have topics of interest which are passionate to you, then don't bother with Adsense, because you won't be able to sustain it. If you aren't literate enough to write about those topics, again don't bother. I see some people on these forums who can't even write a simple question (and I am not talking about those whose native language is not English). It is unlikely that they would be able to generate enough original content for a successful Adsense site.
I started off with a couple of real estate web sites because I have real estate to rent. So when I had a home to rent, I also got side income from the Adsense. Fortunately clicks at that time were still relatively high paying so I made about $40 a month to start. I then put Adsense on some sites about some industries I worked in such as student loans and computer training. Again fairly high paying clicks so I went up to about $100 a month.
My real boost came when my insurance broker screwed up my renewal on my policy, which cost me $500. I was so annoyed that started a web site about insurance in my area, just to tell my story. It now should generate me nearly $2000 a year. http://www.FloridaHomeownerInsurances.com if any one is interested.
Whenever you get excited about something or have an experience, then create a web site. Sometimes it works, sometimes it doesn't. I saw a movie (Cinderella Man) where a historical character was unfairly portrayed, so I came up with http://www.MaxBaerBoxer.com. It sometimes gets a lot of traffic, such as when the movie shows on TV. The clicks are worth peanuts, but over a couple of years I am sure it will pay me back for the work I put into it.
Sometimes your best performing site will give you zero for the day, but a quiet site will have a spike in traffic and make up for it.
Diversify as much as possible. Create lots of VRE: virtual real estate. You will get traffic from long tail search terms and the more sites you have, the more money you will get. Like in all sales, it is a numbers game.
