Found this interesting tool when I was working through a writing course; Lulu Titlescorer, which promises to score your prospective book title, based on a formula.
Be forewarned, just typing in your title isn’t going to be that easy. You’ll need to know whether your title contains verbs, adverbs, adjectives, concrete nouns, or a preposition and an article, or whether it’s a grammatically complete phrase, or a possessive case with noun, or a noun with a noun, and so on.
The best I could come up with, while playing around with some titles for my novel, was a 55.4%, but I got lower than that when I typed in titles like Gone with the Wind, and To Kill a Mockingbird, so maybe I filled the fields incorrectly and you’ll have better luck.
So, give it a try and let me know what you think. Yah or nay, it was still a fun experiment.
(Here’s a little trick; if you aren’t sure whether your title is full of nouns, verbs, concrete nouns, adjectives, etc., just go to Dictionary.com, and type the word in. The definition will tell you what it is).
Here’s what the Lulu Titlescorer says about this tool:
The Lulu Titlescorer has been developed exclusively for Lulu by statisticians who studied the titles of 50 years’ worth of top bestsellers and identified which title attributes separated the bestsellers from the rest.
