Introduction

Ad copy is the written content in advertisements designed to persuade users to take action, such as clicking, purchasing, or signing up. 

It plays a key role in marketing by influencing consumer decisions and reinforcing brand identity. The term “copy” originates from traditional advertising, referring to the text used in print ads and commercials. 

Well-crafted ad copy can be the deciding factor between a user engaging with an ad or scrolling past it.

Ad Copy: The Role of a Copywriter

A copywriter crafts persuasive and engaging messages that resonate with the target audience. 

Unlike general content writing, which focuses on informing or entertaining, ad copywriting is about prompting action. 

Skilled copywriters analyze customer behavior, use emotional triggers, and align messages with brand goals. 

Notable copywriters like David Ogilvy and Eugene Schwartz shaped modern advertising with strategic messaging that drove conversions.
