When writing blog posts in WordPress it’s typically best (from a design perspective) to not display the entire post if it’s really long. The easiest way to do this is by cutting the post off midway and inserting a “Continue Reading” link where the post gets cut-off. This is exactly what we do on our posts.
This is actually extremely simple to do, the functionality is built right into the WordPress visual editor. To cut-off a post and insert a “Continue Reading” link, select the place where you’d like to insert it at and then click the “Insert More Tag” icon in the visual editor (or click Alt+Shift+T).
