You don’t have a blogging policy since you don’t have a blog, but that’s no reason not to create one.
So here’s what can be done. Set up some house style rules and moderate posts prior to approval, at least to begin with. Assign somebody to be Blog Ruler/King, in charge of all content across the blog. Write a ‘how-to blog’ guide and distribute it to those employees / people you want to contribute. Soft launch the blog for a month before making it open to the public. If you talk about your company news, rather than the subject area in which your company operates, then the best person to write about it is an employee who is closest to the action.
Blogging is an investment into PR and SEO. It builds reach and heightens visibility and reenforces PR. It solidifies a community, helps the organisation get closer to the customers. It gives the organisation a voice. Remember that not all corporate blog content needs to be about the business. Don't get stuck in the we-are-not-interesting-enough trap
I think corporate blogging should start with a keyword strategy, just like SEO. Blogs should become a very useful part of your SEO strategy. Then there’s the PR value, with other bloggers writing about and linking to your blog posts. On top of all that, there’s the ability to take part in conversations with customers. Just think about the insights these conversations give, into ones website, products, customer services, pricing… all this feedback is highly valuable, and with a blog one can avoid paying a research company to unearth customer feedback…
