Admin Title Check shows whether the title has already been used while adding or editing a post, page or custom post type.
The title check happens while typing in a title while adding or editing a post. Published (including privately) posts, pages and custom post types with exact or similar titles will be displayed beneath the title. These helps prevent duplicate titles and aides in crafting new titles by finding similar ones.
The purpose of the plugin is mainly to avoid duplicate titles. There is no easy method for knowing whether the current title has already been used when adding a post. It is possible to check the slug after saving a post: a “-2” is appended to the posts’ slug if the posts’ permalink already exists, but this is not an ideal way to tell if titles have been duplicated since permalink structures vary and sometimes stop word are omitted from the slug. This plugin avoids that uncertainty and has the added benefit of showing similar titles.
