Post excerpts are summaries of your posts that can be used as links in your website.
Excerpts are typically short paragraphs, useful for introductions, commonly shown on news or blog areas, as shown below:
By default, WordPress automatically generates an excerpt from the content within your post.
You can customise the excerpt by clicking on the post you wish to edit and in the right-side options panel, click the drop-down arrow next to Excerpt as shown below:
You can now add your text excerpt to this box and save the post.
We recommend keeping the excerpt short and related to the post content.
