Your Shopify store comes with a powerful built-in blogging engine. Blogs are great for content that you’ll be updating regularly. While many stores maintain only one blog (probably called "News" or "Journal") some create multiple to better categorize information including customer stories, tips, tutorials, FAQs and more.
You'll do all your blogging in the Shopify admin (to get your Shopify blog up and running, see their instructions), but when it comes to customizing how your blog(s) display, you'll do that within the theme editor. Just navigate to the blog or article page in the theme editor, and you'll see a section pop up, giving you access to settings specific to that page.
The blog page provides visitors with an index of all of your latest blog posts. Some stores choose to rename this page "News" or "Journal"—what you call it and how you use it is up to you!
You can add content to your store's blog by navigating to Online Store>Blog Posts in the Shopify admin. For more information and tips on how to get your Shopify blog up and running, see their instructions.
To access the settings for your blog page, navigate to it in the theme editor and then click Blog pageunder the Sections tab.
Here, you can choose how many articles to display per page, as well as whether or not to show an RSS link, tags, the post author, or a blog excerpt (visitors would have the option of clicking through to see the full post).
Every time you publish a new blog post to your store's blog, Shopify will generate a new page and URL for it. To access the settings for these pages, navigate to a post—any post—in the theme editor and then click Blog posts under the Sections tab.
Here, you can choose whether or not you want to display tags or the post author on your posts by checking the box beside each option. These settings will apply to all of your blog posts.
You can also choose how you would like visitors to be able to share your posts. The methods you enable will display as a "Share" link on your blog post that will reveal the icons for the networks you've enabled. Like so:
