A keyword-rich subtitle for non-fiction
In non-fiction the subtitle does the heavy lifting. The title can be clever, but the subtitle is where you make the promise clear and include the words readers actually search. Describe your book and who it helps, and get subtitle options built to convert and to be found.
Why does the subtitle matter so much in non-fiction?
A non-fiction reader is buying a solution, and the subtitle is where you name it. It is also indexed by Amazon and often carries the keywords that make the book findable. A vague title with a sharp subtitle outsells a clever title with none.
What should a subtitle include?
The outcome the reader wants, the audience it is for, and sometimes the method or timeframe. "A Simple System to Pay Off Debt in 12 Months" states the result, the approach and the promise in one line, and it contains the words someone would type into search.
How long should a subtitle be?
Long enough to make the promise clear, short enough to read at a glance, usually eight to fifteen words. Keyword stuffing hurts, so aim for a natural sentence a human would say, that happens to contain the terms readers search.
Frequently asked questions
Do fiction books need a subtitle?
Rarely. Subtitles are a non-fiction tool. In fiction the series name does similar work.
Should the subtitle have keywords?
Yes, naturally. Amazon indexes the subtitle, so the words readers search belong there, phrased as a real sentence rather than a keyword list.
How long should a book subtitle be?
About eight to fifteen words. Clear enough to promise a result, short enough to scan.
Can I change my subtitle later?
Yes, though on some retailers it counts as metadata that can take a little longer to update than the description.
