Many webmasters assume that if they keep posting long stories, they will get more traffic and achieve a better reader retention rate. Not everyone will have time to read through long posts though. Even the most popular websites have a mix of long and short posts to keep their readers interested. The Estimated Post Reading Time plugin is a useful tool that lets you inform your visitors how much time they will have to spend to read your posts.
Estimated Post Reading Time is pretty simple to use. Simply define a WPM speed and choose where you want the plugin to work. You should probably go with a reasonable reading speed. The plugin does have a shortcode ‘est_time’, which allows you to display the estimated post reading time anywhere.
Estimated Post Reading Time may not be appropriate for every site. It could help your visitors decide whether to read your posts or save them for later though.
