A/B Testing Idea #255 - Utilize numerical values to convey more persuasive messages

Tactic_Utilize numerical values to convey more persuasive messages


Most people have a strong tendency to ignore generic and basic information and prefer to focus on recent or specific information.

Therefore, in your content and titles, insist on statistics or specific elements in order to attract the attention of your users to them and persuade them. You can give "a boost" to your numbers by being creative whilst still being accurate.

For example, you could say "100% of customers active within the last 30 days would recommend us" instead of "75% of all customers would recommend us".
