Narrow down your niche. Don't just blog about widgets. blog about the benefits of widgets. Blog every day. Have a blog listed at more than one site. When you develop a readership, you're more likely to increase your profits.

Blog about some area you have some knowledge in or would like to know something about or at the very least are interested in. If you try to write a great blog based around some hot keyword yet it's something you could care less about, you'll likely not likely going to stay . You'll get bored and frustrated with the lack luster results.

Have fun do some testing and see what works best for you. You can blog based on your own opinion or something factual. Opinionated bloggers get great traffic. So controversy sells well !!!

Product reviews are getting more and more popular as are service or a movie review. Visit other blogs and notice how many readers they're getting. Above all, have fun. After all, it's free and if you stick to it you'll see your Google Adsense dollars adding up.
