Short Banner Ad Copy Generator

When you ask an AI for banner copy, it usually produces full, descriptive marketing paragraphs. Handing those over to a designer leads to requests to cut the text down, resulting in awkward fragments. Short, punchy ad copy shouldn't be chopped down from long sentences; it needs to be written short from the start.

The first paragraph establishes the real-world context of display ads: people only glance at banners for less than a second. This framing keeps the AI from trying to over-explain and forces it to focus on impactful phrases.

In the Task paragraph, specifying "clusters, not sentences" and splitting the copy into Primary and Secondary lines is crucial. Banner designs use two distinct typographic hierarchy levels, so generating both lines together allows them to drop directly into a layout. The "Angle Focus" column in the Format table helps you quickly compare diverse creative directions. Without this directive, the AI often repeats the exact same discount angle across all 10 options.

The Constraints prevent the most common display ad pitfalls: headlines that don't make sense alone, or hallucinated promo dates and discount amounts. Once you get the table, pick your favorite option and follow up with "Give me 5 more variations of #3" to quickly refine the winner.

This prompt will produce generic, long-winded sentences like "Get your farm-fresh vegetables delivered straight to your door tomorrow morning." These won't fit inside a banner layout without shrinking the font to an unreadable size. Without explicit offer details or a two-tiered headline structure, designers are forced to manually rewrite and reformat everything.
