Book titles are the first thing a potential reader sees. A book title should hook your target audience and convey a little bit about the plot and tone of your book. A good title will generate interest and intrigue readers without giving away too much plot.
Hence, if you have decided to publish a book, decide on the title first.
The attributes of a good book title are:
Some steps as to how to proceed
Step 1: Get clarity on your book goals
Step 2: Brainstorm several potential titles
Step 3: Make sure this title is not already popular
Step 4: Pick your favourites & test them
Test #1: Imagine people saying the title
Test #2: See what people click on
Convert your book to e-book if you want to publish it on KDP. A professionally done book cover will attract plenty of audience but a short memorable book-title will make it even more popular.
Hire an illustrator for the book cover designs. A book layout designer is important as well for a professional layout. So are the other aspects of book-publishing such as editing, formatting, etc.All these factors in conjunction with a short, catchy book title will help the book to be popular.
