Moreover, using all caps is not a recommended way to engage users, as it’s akin to yelling. Perhaps promotional print content is a fine medium for this style, but web isn’t. If your content is structured in an optimized way, using appropriate and descriptive titles and headings, lists, inverted pyramid style, keywords close to the left hand margin, and concise copy, then there shouldn’t be a need to use caps for emphasis.
Part of transitioning to a media publishing mindset requires a change in structure and process to create content at the speed of culture. The old model you see on shows like Mad Men is too slow and cumbersome. By the time an idea becomes an ad, it is out of date. Marketers are increasingly co-locating insights, creative, production, legal approval, and placement to increase interaction and speed in producing and distributing content. Marketing content production is transforming from an advertising agency model to a newsroom model.
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.
