5 Tips to Follow When Coming Up With A Number-Forward Book Title
- Be specific and relevant: Ensure that the number you use in the title accurately represents the content of your book. Whether it’s a specific number of tips, steps, years, or examples, make sure it aligns with the main theme or concept of your book.
- Keep it simple: Stick to single digits or straightforward numerical sequences that are easy to understand at a glance.
- Use odd numbers: Research suggests that odd numbers tend to be more attention-grabbing and memorable than even numbers. Consider using odd numbers in your title to make it stand out and pique curiosity.
- Consider symbolism: Certain numbers may carry symbolic significance, so consider incorporating numbers that hold relevance to your book’s subject matter or target audience. For example, 7 Habits of Highly Effective People uses the number seven to imply completeness or perfection.
- Avoid overusing clichés: While numbers can add intrigue to a title, be cautious not to rely too heavily on clichéd phrases or formulas (e.g., “101 Ways to…”). Instead, strive for creativity and originality to make your title stand out in a crowded market.
