Why AI-Generated Creatives Work on TikTok
AI gives you speed and volume. Both matter on a platform where creative fatigue sets in fast.
AI enables fast creative iteration and testing
One brief can produce dozens of ad variations in minutes. Research shows AI-generated visuals can match or outperform professional stock photography in click-through rates. The key is a clear brief and solid brand context going in.
TikTok's algorithm rewards authentic, high-quality visuals
TikTok prioritizes ads that feel native to the feed. That means crisp visuals, real-looking people, and content that matches the platform's energy. Per TikTok's Business Help Center, creatives must meet minimum resolution thresholds or face rejection. Generic or low-quality outputs will not pass review.
Reduce production time and costs while scaling ad variations
Traditional creative production takes days. AI cuts that to minutes. You get more variations, faster tests, and better data without growing your team.

Step 1: Understand TikTok Ad Formats and Creative Requirements
Get the specs right before you generate anything. Wrong specs waste time.
TikTok supports images, videos, carousel, and collection ads
TikTok Ads Manager supports single video, carousel, and collection formats. Each serves different goals. Pick the format that matches your campaign objective.
Core aspect ratios: 9:16 (vertical), 1:1 (square), 16:9 (horizontal)
9:16 vertical dominates in-feed and streaming placements. Build for that first. Adapt to other ratios if your placements require it.
Max file size 500MB for videos; images must be JPG or PNG
Per TikTok's Business Help Center, images require a minimum resolution of 720×960px and must be JPG or PNG format. Videos must be under 500MB. Ideal in-feed videos run 21 to 34 seconds.
Best practices: minimal text, authentic tone, people-centered visuals
Keep on-screen text minimal. Lead with visuals, not copy. People-centered content performs well because the TikTok feed is already full of creators, not polished brand campaigns.

Step 2: Generate Your AI Ad Creative
Start with your brand, not a blank canvas.
Define your brand voice and key message with a Brand Profile
A Brand Profile stores your guidelines, tone, and product details. Every creative you generate pulls from that context. Consistent inputs produce consistent, on-brand outputs.
Use an AI image workflow to create your visual assets
Feed your brief into an AI creative workflow. Specify your product, target audience, and the exact format you need. Strong inputs produce strong outputs. Vague briefs produce generic ads.
Generate multiple variations to test against each other
Do not stop at one creative. Generate three to five variations with different visual treatments. Test them against each other to learn what resonates with your audience.
Ensure creatives align with your product and target audience
Review every output before uploading. AI works fast, but human review catches anything off-brand or policy-violating. TikTok rejects creatives that mislead viewers or violate platform policies, including AI-generated images that make false claims about real people.

Step 3: Resize and Optimize for TikTok Placements
Format your creatives before you upload. Resizing after the fact loses quality.
Use Smart Resize or manual editing to fit TikTok's aspect ratios
If your creative is the wrong ratio, resize it before upload. Smart Resize preserves your focal point when switching between aspect ratios.
Verify image resolution meets TikTok minimums
Confirm your image is at least 720×960px. TikTok's creative guidance recommends HD resolution (720p or above) for all streaming ad placements.
Test previews in different placements before launch
Most ad tools include a placement preview. Use it before you submit. A creative that looks great at 9:16 may crop poorly at 1:1.

Step 4: Upload and Configure Your Ad in TikTok Ads Manager
This is the native TikTok workflow. Coinis does not publish directly to TikTok today. TikTok integration is on the roadmap. For now, download your creatives from Coinis and upload them here.
Log into TikTok Ads Manager and create a campaign
Navigate to TikTok Ads Manager. Choose your campaign objective (awareness, traffic, or conversions). Set your budget and schedule.
Upload your generated creatives to the ad group
Inside the ad group, select your format and upload your AI-generated images or videos. Match each asset to the correct placement specs.
Add display name, ad text, CTA, and tracking URLs
Fill in your display name within the character limit. Write a short ad text. Choose a CTA button. Add tracking URLs for your analytics setup.
Preview your ad in different placements and submit for review
Use the preview tool to check how the ad appears across placements. When everything looks right, submit. TikTok reviews the creative before it goes live.

Frequently Asked Questions
What aspect ratio should I use for TikTok ads?
9:16 vertical is the recommended format for most TikTok placements, including in-feed and streaming ads. You can also use 1:1 (square) or 16:9 (horizontal), but vertical performs best on mobile. Per TikTok's Business Help Center, a minimum resolution of 720×960px is required for image creatives.
Can I use AI-generated images in TikTok ads?
Yes. TikTok Ads Manager accepts AI-generated images as long as they meet creative specs (JPG or PNG, minimum 720×960px) and comply with platform policies. Avoid any AI-generated content that makes misleading claims about real people, as TikTok will reject those creatives in review.
Does Coinis publish ads directly to TikTok?
Not yet. Coinis currently publishes directly to Facebook and Instagram. TikTok integration is on the roadmap. You can use Coinis Image Ads and Brand Profile to generate and refine TikTok-ready creatives, then download and upload them to TikTok Ads Manager manually.
How many ad variations should I generate for TikTok?
Generate at least three to five variations per campaign. Different visual treatments will perform differently across audiences. Testing multiple creatives early helps you find top performers faster and avoid wasting budget on a single untested concept.
