Ad Copy explained

Ad copy is the voice of your ad. The visual grabs attention, but the copy closes the deal. You can have the best image in the world, but if the words underneath it are boring, nobody clicks.

The best ad copy follows one simple rule: say one thing, say it clearly, and make the reader feel something. Not three things. Not five things. One clear benefit that matters to the person reading it.

There are a few frameworks that work consistently. PAS (Problem-Agitate-Solve) calls out a problem, twists the knife, then presents your product as the solution. AIDA (Attention-Interest-Desire-Action) walks the reader through a logical sequence. But honestly, the framework matters less than the specificity.

"Lose weight fast" is generic garbage. "Drop 12 pounds in 30 days without giving up pasta" is specific. Specificity is what separates ad copy that converts from ad copy that gets ignored. Numbers, timeframes, and concrete outcomes make claims believable.

The other factor is voice. Your copy should sound like a person, not a corporation. Read it out loud. If it sounds like something a real human would say to a friend, it is probably good. If it sounds like a press release, rewrite it.

Short copy works for impulse purchases and retargeting. Long copy works for higher-ticket items and cold audiences that need convincing. There is no universal "right length": the copy should be as long as it needs to be to make the sale, and not a word longer.

Examples

  1. 1Headline: "Your accountant charges $300/hr to do what this app does in 2 minutes" (specific, benefit-driven, creates urgency)
  2. 2Body: "I used to spend 3 hours every Sunday meal prepping. Now I spend 20 minutes. Here is what changed." (personal, relatable, curiosity-driven)
  3. 3CTA: "Start your free trial. Cancel in 30 seconds if it is not for you" (removes risk, reduces friction)
  4. 4Hook: "Delete Canva. You do not need it anymore." (pattern interrupt, bold claim that demands attention)

Common questions about Ad Copy

How long should ad copy be?
It depends on your audience temperature. Cold audiences need longer copy (150-300 words) to build enough interest and handle objections. Warm retargeting audiences respond to short copy (1-2 sentences). For video ads, the spoken script is your copy. Keep it under 60 seconds for most platforms.
What makes ad copy convert?
Three things: specificity (real numbers and outcomes instead of vague promises), empathy (show you understand the reader's pain), and a clear CTA (tell them exactly what to do next). The best ad copy sounds like it was written for one specific person, not a mass audience.
Should I use AI to write ad copy?
AI is great for generating first drafts and variations quickly. But generic AI copy sounds like everyone else's generic AI copy. The best approach is using AI trained on proven direct-response frameworks and then editing the output with your brand voice and specific claims.
How do I test ad copy?
Test one variable at a time. Start with hooks/headlines (they have the biggest impact on CTR). Run the same visual with 3-5 different headlines. Once you find a winning hook, test body copy variations. Then test CTAs. This systematic approach tells you exactly what works.
