What's in a Book Subtitle? The importance to further Promotion

Book sites search engines often consider book titles in a variety of ways, including to recommend similar books with the familiar refrain of 'If you enjoyed this book you may enjoy ..'

Both your book title and subtitle are ways to get your book additional recognition - both on book sites and on search engines.  The more information you add, the more opportunity for your book to come to readers attention if readers search particular subjects on book sites, or on search engines, and words in your title/subtitle match.

Consider your book's subject and how readers might come across it as they search, or, for example, whether there are any large publicity events coming up - via a release of a new film, or historical event - that your book's title and subtitle might link into.   

You don't necessarily need to add a subtitle on your book's cover, but consider adding in your book's information, including our subtitle field, to make the most of your title and subtitle to further reach more readers.
