Yes! One of those non-negotiables is having a blog. A blog is an essential part of social media marketing, in addition to all the advantages, it offers on its own, like boosting your authority as an industry expert and consistently delivering new, keyword-rich content to please the search engines. A link to a blog post is one of the best types of content to post on social media, especially now that Facebook has changed its algorithm. Without regularly sharing new blog posts, you won’t have nearly as much to discuss with your followers and won’t be bringing as much traffic to your website.
