Strong ad performance starts long before targeting. If your creative is weak, no audience or campaign setup will save it. That is why building high-converting ads demands a clear method: stop the scroll, communicate value fast, and connect with where the user already is in their buying journey.

What makes an ad actually stop the scroll?

An ad that performs well meets a short list of conditions. Miss one and the budget burns without results.

• It interrupts the scroll and turns attention into action.
• It communicates a clear value, so you know exactly what you want the user to do.
• It includes an obvious call to action, both visual and written.
• It connects with the user's intent, matching where they are in the funnel.

And here is the part most people skip: if a user is already comparing options or close to buying, hitting them with a brand-introduction ad can break the process instead of accelerating it.

What makes an ad high-converting? An ad that stops the scroll, delivers a clear value, includes a direct call to action, and matches the user's stage in the funnel. Without these four, conversions drop fast.

Which copywriting principles should you follow?

Good copy sounds like your user, not like a brand trying to sell. If your text feels too casual or too formal, the reader spots the ad in seconds and keeps scrolling.

A few principles that consistently move the needle:

• Speak the way your user speaks.
• Hit pain points using contrast to hold attention.
• Add a clear call to action in copy, visuals, and message.
• Test multiple hooks, the opening of your video, copy, or image.
• Write with clarity, you are sending a message, not writing a poem.

You are not chasing style points. You are chasing comprehension and action.

How do I write a hook that works?

The hook is the first line of your video, the first words of your caption, or the headline inside your image. Test several versions in parallel. The winning hook is the one that holds the user past the first three seconds, not the one that sounds smartest in your head.

How can I use ChatGPT prompts to create better ads?

There are two prompts available in the course resources. The first one helps you generate ads from scratch by asking five guided questions about your product and audience.

Using the example of high-end dresses, the prompt asks:

• What do you sell?
• What benefit or transformation does your product offer?
• Who is your ideal customer?
• What level of intent does the audience have?
• What ad format do you want to create?

With those answers, ChatGPT proposes five communication angles you can test. In this case it returned status or identity, FOMO, silent comparison, mental reframing, and silent social proof. Picking the first angle delivered a structured 30 to 45 second video script for the middle of the funnel, plus a copy out using the AIDA formula (attention, interest, desire, action), a headline, a description, and a bolder polarizing version as a bonus.

The takeaway: do not copy the output word for word. Use it as raw material and apply your own brand criteria.

What is AIDA in ad copy? A four step formula: attention, interest, desire, action. You open by grabbing the user, build interest, create desire for the product, and close with a direct action.

How do I validate ads I already have running?

The second prompt grades existing ads. It asks five setup questions before evaluating:

• What is the main objective of the ad?
• Who is the target audience?
• Which platforms will it run on?
• Where in the funnel does it sit?
• Is there an associated landing page?

When you connect a landing page, like platzi.com in the example, the prompt analyzes it and checks whether the ad message and the landing are aligned. Then you paste the copy and upload the creative.

What does the ad evaluation actually measure?

The output gives you a structured diagnosis instead of a vague opinion. For a MOFU ad about a Meta Ads course, the evaluation covered two layers.

Message evaluation:

• Message clarity.
• Persuasive power.
• Alignment with funnel intent.
• Differentiation against average ads.
• Use of mental triggers.
• Coherence with the offer and next funnel step.

Visual evaluation:

• Visual or textual hook in the first three seconds, scored 8 out of 10 in the example.
• Visual hierarchy and ease of understanding.
• Typographic legibility.
• Coherence between visual and verbal.
• Visibility, clarity, and platform adaptation.

The ad scored a final 8 out of 10 as a solid MOFU piece, with priority recommendations: add a clearer call to action, reinforce the benefit visually, test a more confrontational headline, and rework a layout where an ascending graphic was competing with the text.

That last point matters. The graphic might be distracting, or it might be the exact element stopping the scroll. The prompt gives you a baseline, your criteria closes the loop.

Try both prompts on a new ad and on one already running, then drop your results in the comments to compare angles and scores.
