This is the third part on Marketing Psychology, you can read about the previous psychological sales tactic here.
Using specific numbers in your headlines makes your statements feel more credible.
“Learn how to make $4,360 in 30 days selling beats online.” is more specific and therefore more believable than saying “Learn how to make 5K a month selling beats online.”
“Jessica lost 14.8 pounds in 31 days.” is more specific than saying “Jessica lost 15 pounds in a month.”
Remember when using numbers to be specific because it is more likely for readers to believe your claims. Of course, do not ever make false claims.
