There are many blogs online that you can use to find out how to make money with your blog. My personal favorite right now is ProBlogger.com but there are others you can google to find that are worth reading.
One word of advice. The one page, hard sell blogs usually have nothing that you can`t find with a little reading and googling around. Building a profitable website is a process, not an event.
You can certainly make money with a blog. I have been writing a blog for a little over a year and I make about $400 a month. I know of people who make thousands a month. But it has to be a quality blog about something you love and have knowledge about.
And you have to be prepared to spend a lot of time on it. Writing a blog is more time consuming than it seems on the surface. It takes months and months to build up your readership to a point where the income is significant.
It`s all depends on your blog`s niche. The higher paying keywords are harder to attract traffic for because of intense competition. I agree that you must provide high quality content. If you are passionate you should be able to generate significant revenue if you stick at it. It takes months to build up your blog so that it`s generating solid revenue.
This is very true. Slowly slowly cachee monkey. Unless you can hit on a real hot topic that will generate a ton of traffic as well as giving you good adwords with a high return. The Holy Grail of all adsense entrepreneurs.
