I've written before about how Help A Reporter Out can get you press and exposure. It's a free service where people nationwide can submit a query when they are writing a story, article for a magazine, or a book. There are writers in every industry looking for products, services, experts, and so on, and you can respond to these queries instantly, often being quoted or linked to from their story! There's a short blog post on that, if you want a little more information click here.
But the other reason you may want to use HARO is to create your own awesome and original blog posts. Sometimes it is hard to find the time to write really great content when you're so busy operating a business. When other experts send you their advice, opinions, and outlooks on topics, the blog post will practically write itself. Once I wrote a story on Julia Child and how she inspired people and taught them to cook. I had so many amazing people write in their experiences, and it made for a great original piece, and the content just came right to my inbox.
Think about your target audience, what they'd want to read, and maybe try reaching out through HARO to create a series of posts that are content rich and completely unique to your blog.
