Numbers have always been great at arousing curiosity. Especially in headlines.
When people see numbers, like “top 10 bread-baking shortcuts for non-bakers,” those who fall within that target market will wonder, “what are they?”
Other examples include: “10 fears people are afraid to talk about.” “Turn your marriage around in 24 hours or less!” “How to lose inches off your gut in just 30 days.” “Join 10,000 satisfied clients today.”
But here's a mini-tip.
A powerful tool is specificity. The more specific you are, the more credible your copy will be. Often, really obscure numbers, like 17 or 23, can catch people's attention. But they also connote greater believability as they seem harder to make up.
So instead, use: “9 fears people are afraid to talk about.” “Turn your marriage around in 18 hours or less!” “How to lose 2.5 inches off your gut in just 27 days.” “Join 9,973 satisfied clients today” (or “become our 9,974th satisfied client today”).
