Is making money blogging even possible, and a full-time income at that?
Well, I've been reading an e-book that talks all about making money BLOGGING. It's called Blogging to the Bank.
According to this book, making money doesn't necessarily come from blogging insomuch as it comes from advertisements (affiliate links, etc.) optimally placed in and around your blog. You also have to have a specific focus for your blog, one that people will want to read about.
Of course, you can have more than one blog talking about more than one topic, but the money seems to be in focused/targeted topics. It is a somewhat aggressive approach to blogging since you are actually having to blog about topics that will make you money. That way you will get targeted traffic to your site, traffic that will more than likely click on your links (Google Adsense links, affiliate links, etc.) since they are interested in the information in your blog.
