Article excerpts give publishers more flexibility to control what text is used for the table of contents (in reading view and native app), article lists in the library and article description metadata for better SEO.
The amount of text that will be visible in the table of contents varies depending on the presence and size of a thumbnail image.
To add or edit an article’s excerpt, log into the publisher dashboard and choose the article you wish to edit. On the article editor screen, just below thumbnail images, you will see the excerpt field.
It’s best practice to limit the excerpt to 155 characters. No HTML formatting can be used.
Once you are done entering the excerpt, save the article. Your changes will appear immediately in the reading view table of contents.
