Overview
The Blog feature lets you create, maintain, and publish articles on your Site. It also gives you tools to edit your individual post and blog designs, letting you provide a reliable stream of personalized content to attract visitors and create interest in your Website.
Note: If you currently have a blog and want to update to the newest blog platform, see Updating an Old Blog to the New Blog Platform.
Guide
Creating Blog
Click Blog on the left menu.
Click the Add Blog button.
Congratulations! Your blog is ready to use!
All Posts
The All Posts widget is added by default to a new blog page when you add a blog to your Site from the Blog menu. By default, it shows a list of every post on your blog. You can customize the All Posts widget by adding other widgets to modify the page. Simply drag the desired widgets onto your blog from the left menu. 
Search Posts
The Search Posts widget lets visitors search for specific posts or themes in your blog so that they can more easily find articles that interest them.
Manage Posts
Add, publish, unpublish, edit, or remove posts from your blog. 
Blog Settings
Change the thumbnail, name, title, description, and backups for your blog. You can also find your blog's RSS feed URL here. Adding a blog name, title, description and URL are important because they help with the SEO of your blog. The more keywords used in your name, title and description, the more relevance your blog will have on search engines. For example, using the term "food blog" in your blog name, title, description and URL will help search engines find your blog when a user searches for the term "food blog".
Blog Tags
You can categorise your blog posts by adding tags onto your posts. Click Blog on the left menu, then click Manage Posts.
Choose a post to edit and click the Edit button.
Scroll down to the Tags section and add a tag. Click the Enter key.
Tags will be grouped into categories, so you can filter your posts based on tags in the All Posts widget. You can add the All Posts widget onto multiple pages and sort the posts by their tags in the Content Editor.
Blog Backups
Click Backup Blog to backup your blog posts. The blog backup is separate from the general Site backup found in Site settings, and is the only way to backup and save your post content.
Edit Post Design
Change the design of the blog post page. Any changes you make to this page will affect how all posts are displayed on your blog. You can add widgets to enable additional text, graphics, social media, and other effects. Editing the post design only changes the general layout of posts by adding or deleting widgets, rows and columns. This does not let you change the text or graphics of an individual post.
Import Posts
Warning: On the new Blog platform, RSS feed is not yet available.
Import blog posts from an RSS feed. All Blog posts will be imported, while in each post, only the elements which are supported in the blog feature will be imported: text (H1 / H2 / H3, paragraph), images, videos (Youtube / Vimeo), HTML elements, dividers and disqus comments, as well as post author and post date. After the import, the imported posts are in draft mode until published by the site's owner.
Considerations
Blog Backups
Blog backups act separately from Website backups. When backing up your Website, your blog posts will not be backed up. Remember to backup your blog posts whenever adding new posts or editing existing posts.
Change Blog Author Manually
You can add in a blog author manually by entering a blog author name as free text. Click the tickbox to enable the manual feature.
