You can "blog" or write about any subject interesting to you. However to be most profitable it should be interesting to other people.
When it's interesting to other people there will be companies willing to pay you for ads on your site.
Don't worry. You don't have to sell advertising. Google handles all of it.
Watch the video and see how easy it is. It's only 4 minutes, 30 seconds.
Note: You probably won't make the car payment from ads on your blog in the first few months but if you keep adding to it and getting visitors, your monthly check will keep growing.
I've recently started testing some of the many money-making programs and systems we see advertised all over the internet.
I started testing an investing system on Monday January 19th with real money and it's made money every day so far. Since January 5th it's only had one losing day. It looks very promising but I'm not ready to give it my seal of approval quite yet.
If you'd like to keep updated on my results for this system and any others I find, please provide your contact details below.
