As I have already mentioned in an earlier post on my 5 Pronged Approach, you must think of your blog as your Home on the Internet, and make it welcoming to visitors. I maintain several blogs, but my main ones for my Core business (helping people to get started with a home business on their computer) are this one, Huge Profits Tiny List, and ConnieGreen.com.
I recommend posting to your blog at least twice a week during the first year, and about once a week after that. Remember that you are in this for the long run, not just for the next month or so, so always be thinking about the future as you build your online empire.
Categories are important here, as is SEO (search engine optimization). I recommend that you use the WordPress SEO plugin from Yoast. It’s free, and allows you to optimize your post for a specific keyword phrase. This makes it possible for you to target the exact topic you will cover, and to reach prospects who are already interested in what you are knowledgeable about. Blogging to build your online business is a valuable and profitable use of your time.
