A blog is a great supplement to a website. 

It can be a place to house more in-depth info, behind the scenes glimpses into your business, or details about the items you have for sale. With the lifespan of a blog post going far beyond that of a social media post, a blog is the perfect place to talk about topics that won't necessarily go stale in a few days. 

Similarly, a blog is a strategic segway into a website. Keep in mind that social media should not be the final destination of clients or potential clients. Share snippets on social media, and provide links back to your blog or website. In the same light, if your blog post is talking about something that is a part of your website, link to it! Use your blog to your advantage, especially going into the holiday season.
