The Blogs & Pages tab is used to add and edit just about any content that does not belong on a product page. Your "Frontpage" is an example of an area for such content, along with the "About Us" page. Both of them are created automatically when you start your shop.

You can import your Wordpress blog into Shopify using our Wordpress importer app.

Additional content importing apps can be found here.

Pages

A page is created and edited as a single stream of content which can be as long as you like. Besides the "About Us" page, here are some other ways that pages could be useful:

• Shipping FAQ: customers might want to know right away whether or not you ship to their country and how much that will cost them. Many will not like having to first find the products they are looking for and then to go through part of the checkout process before they can find out if shipping to their location is even possible.
• Privacy statement: since your customers need to provide personal information in order to buy anything, your shop should include an official statement concerning how that information is used.

Blogs

A blog is a place for ongoing communication with your customers, updated with a new entry whenever you need to tell them something new. You could use your "Frontpage" blog for a main source of news about your shop, with announcements of deals and new products. Here are some other possibilities for blogs in your shop:

• Staff blogs: if you decide it's important to share your business's personality with your customers, you could give some staff members the space to express themselves. Suppose one of your employees is really passionate about a piece of software that you sell; what better way to get your customers excited than to let your employee talk about all the ways they've found to customize and take full advantage of the product?
• Tour diary: a band using Shopify to sell their music or merchandise could easily keep their fans up to date while on the road.
• Artist profiles: maybe you run a shop which sells prints from a wide variety of artists. Why not focus on a different artist each week and give a bit of information about their history and influences?

Comments

Comments offer a way to interact with your customers. Once you enable comments on one of your blogs, your customers will be free to post their comments for each blog post. This creates an opportunity for the customers to interact and share ideas with you, as well as, with each other. Here are some possibilities for comments in your shop:

• New Products: say you have a blog for your shop that allows you to showcase your newest products. By enabling comments on this blog, customers would have a chance to voice their opinions about the new products or make suggestions about what kind of products they would like to see for the future.
• Staff blogs: if you decide it's important to share your business's personality with your customers, you could give some staff members a blog to express themselves. Staff members could then choose to enable comments on their blog and give customers a chance to get to interact with them.
