Enable Excerpts for Pages
Adds the Excerpt box to pages, which many themes and SEO plugins can use as a summary.
Snippet Library
Content snippets for WordPress
Snippets that add to or change your posts and pages: reading time, author boxes, “last updated” notes, content after the post or after a paragraph, and excerpt tweaks. For bloggers, publishers and anyone who wants richer posts without editing theme files.
Key Takeaways Box Before Posts (Blocks)
Adds a "Key takeaways" box built from blocks at the top of every post, a skimmable summary readers and search engines appreciate.
Require an Excerpt Before Publishing
Blocks publishing posts that have no hand-written excerpt, so archive pages, search results and social shares always have a proper summary.
Save an Excerpt Automatically When One Is Missing
Fills in the excerpt field from the first sentences of the post when it is saved without one, so feeds, plugins and APIs that read the stored excerpt always get a summary.
