Titles, of course, attract a lot of attention. If you feel you need a little extra time for your title, you might try using subtitles. If styled appropriately, they just might grab some more of your visitor’s “title attention time.”
While you could add subtitles to WordPress in a very manual way, as usual, there’s a plugin for you that will make the job easier.
Secondary Title Plugin
A plugin you can use for this job is called Secondary Title.
Once activated, you will see a new box in your write/edit screen to insert your subtitle into.
