What makes a good title?
It has to do several jobs at once — identify, intrigue, and be findable — and the balance between them differs completely depending on where the title will be encountered.
What a title must achieve:
Signal the category. A reader should be able to tell roughly what kind of thing this is. A title that could belong to any genre helps nobody find it.
Create a reason to look further, usually through specificity, tension or an unexpected pairing.
Be memorable and sayable, because recommendations are spoken. A title people cannot pronounce or recall does not get passed on.
Be searchable and distinctive. Titles cannot be copyrighted, so duplicates exist — and competing with an established book or film for the same search terms is a self-inflicted problem.
Survive truncation, since it will appear cut short in listings, search results and on a spine.
What works, by form:
Fiction tolerates the oblique and evocative, since the cover and description carry the explaining.
Non-fiction rewards clarity about the promise, frequently a clear main title plus a subtitle doing the explanatory work — the subtitle is where the keywords and the specific claim belong.
Articles and posts are closest to search: front-load the informative words, since the beginning carries most weight for both readers and search engines.
Academic work prioritises precision and findability over elegance.
Common failures: abstract nouns with no image; titles that only make sense after reading the work; being clever at the cost of being clear; overpromising, which produces disappointed readers and poor reviews; and length that will not survive a listing.
The practical process: write thirty candidates rather than agonising over three; test them by saying each aloud and by asking someone who has not read it what they expect; search each to see what it collides with; and check how it looks truncated.
A note on control. In traditional publishing the publisher usually has final say over the title, and changes are common — it is a commercial decision, and the sales team is involved.
