Besides the obvious, you should do another blog. Two blogs will get substantially more activity then a single blog. You can play off of each other and do separate links to each. This will help the cross links you add to each blog have more weight. So now that your business has a blog, next is to CREATE a personal blog. You can do a slew of new articles and original content easily since there is no direct theme you are limited to.
For example Marketing Spot is DWHS Web Hosting‘s Marketing Blog, they also have a Download Blog at Downloadspot.com But the personal blog of DWHS’s President Charles Yarbrough is a essential key tool in the blog marketing and fun plan. I’m not saying to create hundreds of blogs but several with unique original content will help the overall success of each blog more then itself.
