Replace Mass Marketing With a "One-to-One" Mindset in Your Ads

Founders Should Not Write Their Own Ads; They're Too Close to the Product

Sell the Reward, Not the Prevention: Why Pepsodent Sold Beauty, Not Cavity Avoidance

Advertising is Multiplied Salesmanship; Judge Ads by a Salesperson's Standards

A Headline's Only Job Is to Call Your Ideal Customer's Name in a Crowd

According to Claude Hopkins, headlines are not for clever wordplay; their sole function is to identify and attract a specific person from a hurried crowd.

A "78-Second Shave" Outperforms "Quick Shaves" by Using Credible Specificity
