No matter how exciting the content is on your WordPress website, there may arise a situation where you want to only display a controlled amount of information on your home page. Therefore, if the user wants to read more, they can click on the individual post, but the home page remains looking very streamlined and “clean.”
The way you can do this with WordPress is by taking advantage of the excerpt capability. The term excerpt refers to a selected amount of text taken from the body of the post’s content and displaying this on the home page.
There are several different ways to use excerpts. Some WordPress themes, for example, automatically generate excerpts. You can also do it manually from the Post Edit screen.
First, you’ll need to make sure that the ability to manually create an excerpt is activated. After making sure that you’re logged into your WordPress site, click on “Screen Options” in the upper righthand corner. Make sure that the checkmark is activated next to the box labeled “Excerpt.”
With excerpts activated, you have two options to manually create one from the Post Edit screen. The first option is to insert the “!–more–” tag after existing content in your post. This will designate the content before that tag as the excerpt. The second option is to write out a separate text that you want to use as the excerpt. This needs to be written in the “Excerpt” box immediately beneath where the post’s content goes.
Note: The default limit for a WordPress excerpt is 55 words. This can, however, be modified by making coding changes.
Keep in mind that excerpts are not solely used on the homepage. Excerpts are also used with your website’s RSS feed, for search results, and for archived pages.
