How to create AI ad creatives: messaging, images, and evaluation
AI ad creative production uses generative AI to create copy, images, and other advertising assets. Start by deciding whose question the ad answers and what action you want them to take.
More images alone do not explain why performance changed. This guide shows how to prepare a brief, compare messaging separately from visuals, and evaluate inquiries or purchases.
Choose production tools and create the assets
For production steps, choose the guide matching the asset.
- AI ad images and tool comparison: Create visuals with ChatGPT, Canva, or Firefly, then place accurate product photos and copy.
- AI video ads and tool comparison: Use photos or footage with Canva, Runway, or Firefly, then check captions and exports.
For an article destination, use the AI blog tool comparison and SEO workflow. After production, continue below to define comparison conditions and evaluate outcomes.
What AI can do, and what you must decide
Production workflows are becoming more integrated in Japan. LINE Yahoo launched Creative AI Lab Beta on September 7, 2026. Product URLs and campaign objectives can support strategy and image suggestions, chat-based revisions, and resizing. Official announcement
You still need accurate selling conditions, a comparison question, and a definition of success. Treat generated options as candidates.
| Task to request from AI | Evidence to provide |
|---|---|
| Copy variations | Actual product value and supporting evidence |
| Composition or background ideas | Accurate product photos and brand requirements |
| Alternative assets | The variable to change, fixed conditions, and outcome metric |
| A performance review | Actual results, outcome definitions, and concurrent changes |
Review image-to-video transformations
Meta announced broader image-to-video access in Advantage+ creative on October 6, 2026. Catalog product videos remain an eligible-advertiser beta. Official announcement
Check the original image and whether generated motion changes the product's meaning.
| Check | Question |
|---|---|
| Shape and motion | Were nonexistent moving parts, uses, or accessories added? |
| Text and conditions | Do prices and conditions remain visible long enough to read? |
| Audio and captions | Do they promise something different from the destination? |
| Final scene | Is the next action clear? |
| Comparison record | Can you explain what changed between image and video? |
If you also change the headline or price, the result does not isolate the effect of video. Record a comparison of complete ad concepts. Verify generation access and delivery specifications in your account.
Prepare a single creative brief
Product or service:
Intended audience:
What they hesitate about before buying:
Value to communicate:
Supporting facts and sources:
Landing page:
Desired action, such as purchase, booking, or inquiry:
Price, service area, and usage conditions:
Available photos and logos, with usage conditions:
Expressions to avoid:
Advertising channel and verified asset specifications:
Replace vague claims such as “convenient” with information that helps someone decide. For a booking service, this could mean available times, the booking process, or how changes work. This is an illustrative example, not an instruction to invent features.
Compare messaging and visuals separately
The following is a suggested comparison plan.
| Question | Change | Keep fixed |
|---|---|---|
| Which purchase concern should the ad address? | The question answered by the headline | Product photo, price, destination, and action button |
| Which composition explains usage? | The image presentation | Headline, selling conditions, and destination |
| Is the next step understandable? | Wording near the button | Message, image, and actual available action |
Changing messaging, price, background, and landing page together can identify a promising package, but not the contribution of each element. Record it as a comparison of complete ads.
Normal delivery does not necessarily allocate equal exposure to each asset. Distinguish ordinary ad performance comparisons from an A/B test using a platform experiment.
A prompt for ChatGPT or Gemini
Prepare ad creative options using this brief.
Brief:
Question we want to compare:
Elements you may change:
Elements to keep fixed:
For each option, provide:
- The audience question it answers
- Headline and supporting copy
- Image composition and required real assets
- Where the landing page repeats the same promise
- The business outcome and how to evaluate it
Do not invent prices, features, results, or customer testimonials.
Separate ideas needing image generation from those using existing photos.
Do not predict clicks or sales from appearance alone.
Free ChatGPT or Gemini can help organize the brief and copy. Check image capabilities and usage limits in the service you choose.
Match the ad to the landing page before publication
Check spelling, product shape, logo, colors, price, and eligibility. Correct realistic-looking images that imply accessories or experiences you do not provide.
Check that the landing page fulfills the same promise, text is readable at the placement size, and the button describes the actual next step. Review rights and the platform's advertising requirements for AI-generated assets as well.
The official Creative AI Lab guide also calls for review before launch and saving needed images. It does not guarantee ad approval or performance.
Evaluate clicks and downstream outcomes
| Result | What to investigate |
|---|---|
| Clicks and outcomes rise | Whether cost and outcome quality remain acceptable |
| Clicks rise without more outcomes | Ad-to-page consistency, audience fit, and measurement |
| More inquiries are unsuitable | Whether copy explains eligibility clearly |
| Exposure differs substantially between assets | Whether delivery conditions permit a fair comparison |
| Data is scarce | Whether further observation is feasible before choosing a winner |
Keep impression, click, and conversion counts alongside rates and cost. Use the marketing review guide to interpret results, or the landing page improvement guide when the destination is the problem.
Start with a completed brief and one comparison question. Shoryaku AI chat can help discuss tactics and comparison criteria using your business information. Create images and submit ads through your chosen production tool and advertising platform.
