Sometimes easy is better than hard. Finding great blog content for your business blog doesn't have to be a struggle. You can make great use of "OPC" – other people's content. I stumbled upon this tactic while trying to find blog content before going away on vacation.
Remember the old Yellow Pages ad, "Let your fingers do the walking?" Here's how to let your fingers do the heavy lifting. Everything is done by email, except of course the actual posting to your blog, but then, your fingers do the work there too.
The idea is to write a series of interview questions (5-7) about your core topic. Send them off by email to the 10 top experts in your field. Ask them for 5 minutes of their time to complete the emailed interview, and let them know you'd like to feature them on your blog.
Then run the interview series on your blog. This provides your blog readers with valuable, relevant content in addition to your own experiences and perspectives. Your readers will deepen their understanding of your topic.
