The more tag …
<!–more–>
Show the beginning excerpts of your posts so a reader can click the “Read More” tag to be directed to your full post.
You can truncate your blog entries so that only the first part of a posts is displayed on the home and archive pages. When you do this, a link will be placed directly after your excerpt, pointing the reader to the full post. You can put this link anywhere in a post, and customize it to say whatever you want.
Excerpt and Tag are essentially the same thing.
Note: This can depend upon the theme you are using if they work.
