One way to drive traffic to your blog is to use current popular news stories as a jump off point to hook your audience. Readers often search current news stories and, if your post headline contains one of them, the same thought process will have them following the link to your blog post.
For example, emergency preparedness planning was a hot topic during the swine flu pandemic warnings in 2009. Emergency preparedness is less discussed with the story dropping out of the headlines. If you would like to open up the topic again with your clients, try using the Icelandic volcano eruptions and the havoc resulting at UK airports as a jumping off point.
Be sure to include the story headline in your blog post title to have your readers clicking in and keep the post content relevant to keep them there.
