Most posts should be rather short and to the point. Readers typically desire quick access to important information on a blog not extended meanderings through a lengthy topic. But sometimes the blog author may need to write a lengthy post. If you need to publish a long post but do not want it to fill up your main page, forcing the reader to keep scrolling down, down, down to get to the next post, you can use the extended entry.
The material you place in your extended entry does not appear on your main page. Instead, at the end of the main post section the reader will see a link that usually expresses something like this: Click here to continue reading this post. When the reader clicks that link, everything you have included in the lengthy extended section of your post will then appear. I have provided ...
you with an example of what this actually looks like in this post. Notice that a well placed teaser might entice the reader to click on the link to continue reading the post.
While I recommend using the extended entry sparingly, when well used, the extended entry can be a very helpful tool.
Extended entry links usually require the reader to hit the back button on the browser to return to the main index page for the blog. So... click you back button to return to the main page.
