I'm going to build my first blog about eBiznes, Marketing and SEO. I would like to know that you have thematic blogs? What's that thematic? How much people visit your blog. How is your traffic? Do you use Wordpress or another blog system?
Just a suggestion, why not do some research and release a blog that isn't in such an oversaturated market? There are literally thousands of ebiz blogs that are read by exactly one person: the writer. Seriously. Go out and find a niche that isn't so oversaturated and monetize it. If it's good and properly marketed, you can have a loyal reader base in no time.
Big field with a lot of competition. Since you asked, and I love my blog. I started around 45 days ago on my own IP, after 2 months on free hosted wordpress, for 2 months. I'm in a field that is controlled by big companies, but not over saturated at all. "Night Life Entertainment" I really started to pour on the content since I started self hosting. Currently I am getting around 2300-3500 page views a day. and around 280 subscribers, and growing at around 15 a day. Off site clicks on aff links are about 12%.(need to work on that) I am pretty happy about it also. Really quick. IMO
