How to make ads with AI: a complete guide

What an AI ad generator does (and doesn't do)

An AI ad generator takes a prompt, such as a product description, an offer and the platform you want to advertise on, and produces the creative pieces an ad needs. Depending on the tool, that can mean a short video, a set of images, headlines, primary text, a description and a call to action. Some tools, like Qevio, make all of these together from one prompt so they share the same message and style.

What it doesn't do is decide your strategy. It won't know your margins, which customers are most valuable or which claims you can legally make. It also doesn't run the campaign: targeting, budgets and bidding still happen in Meta Ads Manager, TikTok Ads Manager, Google Ads or whichever platform you use. Think of the AI as a fast creative team that needs a good brief.

Step 1: Write a one-line brief before you open any tool

Most weak ads come from a vague brief. Before generating anything, write one sentence for each of these points. If you can't fill one in, the ad isn't ready yet.

• Product: what it is, in plain words. "A stainless steel water bottle that keeps drinks cold for 24 hours."
• Audience: who it's for and what they care about. "Gym-goers who hate warm water halfway through a workout."
• Offer: why act now. "20% off the first order this week" or "free shipping over $40."
• Proof: one reason to believe it. A spec, a guarantee, a review count you can back up.
• Action: what you want people to do. Shop now, sign up, book a call.

Step 2: Pick the ad format for the placement

Each placement rewards a different shape and pace. Generating in the right format from the start avoids awkward crops later, when the product or the headline gets cut off.

• TikTok, Instagram Reels, Facebook Reels and YouTube Shorts: vertical 9:16 video, usually short, with the hook in the first second or two.
• Instagram and Facebook feed: 4:5 portrait or 1:1 square images and videos, which take up more of the screen than landscape.
• Stories: 9:16, with the important parts away from the top and bottom edges where buttons sit.
• Pinterest: tall 2:3 or 9:16 pins with a clear product and room for a short headline.
• YouTube in-stream and websites: 16:9 landscape.

Step 3: Write hooks first, then the rest of the ad

The hook is the first thing people see: the opening shot of a video, the main image or the first line of text. On most social platforms people decide within a second or two whether to keep watching, so the hook matters more than any other part of the ad.

Ask the AI for several hooks before anything else, then choose the strongest and build the ad around it. Good hook angles to try include a problem the viewer recognises, a surprising result, a quick before-and-after, the product in motion in close-up, or a direct question to the audience.

• Problem: "Your water is warm before your workout's over?"
• Result: "Still ice cold after 24 hours in a hot car."
• Demonstration: ice cubes rattling in the bottle, filmed close up.
• Social angle: "The bottle everyone at my gym keeps asking about." (Only if it's true.)

Step 4: Create the video creative

For video ads, describe one clear scene rather than a whole story. AI video models produce the best results with concrete, visual prompts: the subject, the setting, the action, the camera move and the light. Short clips of 5 to 10 seconds are easier to keep sharp and on-message, and you can always generate a few and cut them together.

If the ad must show your real product, start from a product photo and use it as the first frame. That keeps the shape, colour and packaging much closer to the real thing than a text-only prompt.

• Example prompt: "Close-up of a matte black water bottle on a gym bench, a hand twists off the lid, condensation on the steel, slow push-in, bright morning light."
• Keep any on-screen text out of the AI video and add it in your editor or the ad platform, where you control the wording exactly.
• Make two or three visual variations of the same hook to see which one holds attention best.

Step 5: Create the image creatives

Static image ads are still cheap to produce and quick to test, and they often work well for retargeting and catalogue ads. Ask for a clean product shot, a lifestyle scene showing the product in use, and a version with empty space for a headline. Generating several images at once and keeping the best is faster than trying to perfect one.

• Product on a simple background for clarity.
• Lifestyle: the product where your customer would actually use it.
• Seasonal: the same product styled for a holiday or sale.
• Text-ready: "empty space at the top for a headline" in the prompt.

Step 6: Content Write

Content Write has three main parts on most platforms: primary text (the words above or below the creative), a headline and a call to action. Keep the primary text focused on one benefit and one reason to act now. Headlines work best when they are short and specific. Ask the AI for several versions of each so you can test them, and write in your brand's voice so the ads sound like you.

• Primary text: the hook, the benefit, the proof, the offer. Two to four short lines is plenty for most social ads.
• Headline: under about 40 characters, naming the benefit or the offer.
• Call to action: match the goal. "Shop now" for sales, "Learn more" for awareness, "Sign up" for leads.
• Avoid claims you can't prove, such as health results, "best" or "number one", unless you have evidence.

Step 7: Test versions, not just one ad

The biggest advantage of making ads with AI is volume. Instead of betting your budget on a single creative, launch a few versions that differ in one thing at a time, such as the hook, the visual style or the offer. Let them run long enough to collect meaningful data, then keep the winners and make new variations of them.

A simple structure for a first test is three hooks, each with one video and one image, all using the same copy. Once you know which hook wins, test copy and offers on top of it.

How to make ads with Qevio

Qevio's AI Campaign Generator turns one prompt into the pieces an ad needs: a short video, images, a headline, Content Write and a call to action, along with captions, hashtags and keywords if you want them. Describe the product, the audience, the offer and the platform, attach up to 4 product photos (JPG, PNG or WebP, up to 10 MB each) and choose the outputs. The credit price is shown before anything runs.

For the video, pick a length of 5 to 30 seconds (depending on the model) and a shape such as 9:16 for Reels and TikTok or 4:5 for feeds. Product Ad mode is designed to keep your product accurate and central, Fast and Best Value are good for testing hooks cheaply, and High Quality or Cinematic suit the final version. The AI Image Generator makes 1 to 8 images per run, and the AI Content Generator writes extra headline and primary-text variations. Your Brand Kit keeps the voice, colours and logo consistent across every ad.

What to do outside Qevio

Qevio doesn't run ads or connect to ad accounts. Download the videos and images, copy the text, and build the campaign in your ad platform, where you set the audience, budget and schedule. Add exact on-screen text, prices and legal lines in your editor or in the ad platform.

Check every ad before you launch

A few minutes of review protects your budget and your brand.

• The product looks like the real one: colour, shape, logo and packaging.
• Every claim, price and date in the copy is true and up to date.
• Nothing looks odd in hands, faces, text or the background of AI visuals.
• Important parts sit inside the safe area for the placement.
• The ad follows the platform's advertising policies and any rules for your industry.
• If you use creator-style (UGC) ads, they don't pretend to be a real customer review.

Common mistakes to avoid

The most common mistake is launching one ad and judging AI by it. Others include prompts that describe a mood but not a scene, landscape creatives on vertical placements, and copy that lists every feature instead of one clear benefit. Treat AI output as a strong first draft, keep the ad simple, and let testing tell you what works.
