Consider a technical writing certificate. Technical writing is a type of content writing that focuses on communicating technical material through manuals, reports, and online documents. This could be a how to guide, a safety manual for a worksite, or a document on a process or procedure. There is a growing demand for technical writers who can explain complex procedures to the average reader.
Predictably, blog posts are typically written by the bloggers. However, if your team is large enough to have someone dedicated to creating gated assets and premium content -- things like ebooks and tools -- they should also write blog posts to help promote those assets. SEO specialists will also work closely with bloggers, as blog posts are often a company's best opportunity to improve organic search rankings. As such, bloggers should be writing posts that help improve the site's SEO, and drive organic traffic and leads. Their editorial should be informed by keyword research, and optimized for SEO.
