As an owner of a marketing agency, Agency|163, I can state that blogging for agencies is still a vital part of promotion. While social media may engage and attract customers, your company blog will offer credibility to skeptical potential clients, increased search engine optimization, as well as possible back-links to your website in order to increase online promotion.
I would be happy to answer any additional specific questions you may have regarding how content marketing can work for your brand.
