Question 1

What does TikTok actually look for in ads?

Accepted Answer

TikTok's algorithm treats ads like any other content — if people watch, engage, and don't skip, the ad gets shown to more people. The platform explicitly recommends ads that "don't look like ads."

Here's what matters most:

• Hook in the first 1-2 seconds — TikTok measures "thumb-stop rate" (3-second view rate). If people scroll past immediately, the algorithm stops showing your ad. Front-facing camera, someone talking directly to camera, with an unexpected opening line works best.

• Vertical 9:16 format — TikTok penalizes anything that isn't full-screen vertical. Horizontal or square videos with black bars get lower delivery and higher CPM.

• Native audio — Videos with original voiceover outperform videos with just music or text. TikTok's algorithm favors content with speech because it keeps people watching longer.

• 15-30 seconds — TikTok's own data shows this is the sweet spot. Under 15 seconds doesn't give enough time to build interest. Over 60 seconds loses most viewers. The platform recommends 21-34 seconds for optimal completion rates.

• UGC aesthetic — Casual lighting, front-facing camera, real-looking settings (bedroom, kitchen, car). Content shot on phones outperforms studio-produced content by 2-3x on TikTok because it matches the native feed.

All ads generated by inReels are built around these requirements — 9:16 vertical, AI avatar talking to camera with lip-synced voiceover, hook-first scripts, 15-30 second duration.

Question 2

What TikTok ad formats can I create?

Accepted Answer

inReels generates videos optimized for three TikTok ad placements:

In-Feed Ads — The most common format. Your ad appears in the user's For You Page between organic videos. This is where UGC-style content performs best because it blends in. 9:16 vertical, 15-60 seconds, sound-on by default.

Spark Ads — TikTok's native ad format that boosts organic-looking content. You post the video to your TikTok account first, then promote it through Ads Manager. Spark Ads typically get 30-40% higher engagement than standard In-Feed Ads because they look and feel like regular TikTok posts.

TikTok Shop Ads — If you sell on TikTok Shop, video ads drive traffic directly to your product listing. Product demo and review-style videos work best here. The AI can generate scripts that mention specific product features and pricing.

For all three formats, the key is the same: the ad needs to feel like something a real person posted, not something a brand produced. That's why AI-generated UGC with natural-looking avatars works so well on TikTok.

Question 3

What are the TikTok ad specs I need to know?

Accepted Answer

Here are the exact specs TikTok requires:

• Aspect ratio: 9:16 (vertical, full-screen)
• Resolution: 720×1280 minimum, 1080×1920 recommended
• File format: MP4 or MOV
• File size: Under 500 MB
• Duration: 5-60 seconds (15-30 seconds recommended)
• Audio: Required for best performance — TikTok is a sound-on platform

inReels outputs all videos at 1080×1920 in MP4 format, so they're ready to upload directly to TikTok Ads Manager without any conversion or resizing.

Important: TikTok also has a "safe zone" — the top 150px and bottom 140px of the screen are covered by the username, caption, and music info. Keep your main content (face, product) in the center of the frame. Our AI avatars are already positioned within this safe zone.

Question 4

How do I write hooks that stop the scroll on TikTok?

Accepted Answer

TikTok users decide in under 2 seconds whether to keep watching. The hook is everything.

Hooks that work on TikTok right now:

"POV: you finally found [solution]" — Feels native to TikTok's POV format. Doesn't register as an ad.

"I need to tell you about this before it goes viral" — Creates urgency and curiosity.

"If you're still [doing the old way], you need to see this" — Calls out a specific behavior.

"I was today years old when I found out..." — Uses the meme format people already engage with.

Starting mid-sentence — "—and that's when I realized I'd been doing it wrong" — Makes the viewer feel like they walked into something already happening.

Hooks that get skipped: anything starting with your brand name, anything that sounds like an infomercial ("Are you tired of..."), and "Wait — don't scroll!" (worked in 2023, now it's an instant skip signal).

Our AI script generator writes hooks based on these patterns. You can also write your own hook and let the AI handle the rest of the script. For more hook formulas, see our guide on UGC hooks that stop the scroll.

Question 5

How much does it cost to generate TikTok ads with AI?

Accepted Answer

With inReels, you can generate your first ads free — 15 credits on signup, no credit card required.

After that, plans start at $9/month (Hobby). A typical 20-second TikTok ad costs about 1-3 credits depending on the AI model you choose.

For comparison, here's what traditional TikTok ad creation costs:

• Hiring a UGC creator: $150-500 per video
• Video production agency: $1,000-5,000 per video
• Freelance video editor: $50-200 per video
• AI-generated (inReels): $1-5 per video

The real savings aren't just per-video cost — it's testing speed. TikTok's own best practices recommend testing 3-5 creatives per ad group. With traditional methods, that's $750-2,500 per round of testing. With AI, it's under $15 and takes 20 minutes instead of 2-3 weeks.

Question 6

How do I set up TikTok ads after generating the video?

Accepted Answer

Once you've generated your ad video, here's the quick setup:

1. Download the MP4 from inReels
2. Go to TikTok Ads Manager (ads.tiktok.com)
3. Create Campaign → Choose "Website Conversions" or "Product Sales" as your objective
4. Set up your Ad Group — target audience, budget ($20-50/day to start), and schedule
5. Upload your video in the Ad section
6. Add your landing page URL and CTA button ("Shop Now" or "Learn More")
7. Submit for review — TikTok typically approves ads within 24 hours

For Spark Ads (recommended): Post the video to your TikTok business account first. Then in Ads Manager, select "Spark Ad" and connect your organic post. This gives you the organic engagement benefits plus paid reach.

Start with $20-30/day per ad group and test 3-5 creative variations. After 48-72 hours, you'll have enough data to see which hooks and scripts work best. Kill anything with a hook rate below 20% and scale what's working.

Question 7

What kind of products work best for TikTok ads?

Accepted Answer

Almost any product can work on TikTok, but some categories consistently perform better:

Strong performers:
• Beauty & skincare — "Get ready with me" and review formats dominate TikTok
• Fashion & accessories — Try-on and styling videos
• Health & supplements — Before/after and educational angles
• Tech gadgets & apps — Demo and "I found this" discovery format
• Food & beverage — Taste test and recipe integration
• Home & lifestyle — "TikTok made me buy it" unboxing format

The key isn't the product category — it's the angle. Every product needs a "TikTok-native" angle:
• Instead of "Buy our moisturizer" → "The $14 moisturizer dermatologists don't want you to know about"
• Instead of "Download our app" → "POV: you finally found an app that actually does [thing]"
• Instead of "Our supplement works" → "I tried this for 30 days — here's what happened"

Products that struggle: anything that requires long explanation (B2B software), very high-ticket items ($5,000+) where impulse purchase doesn't apply, or anything that can't be demonstrated visually.

Question 8

How many TikTok ad variations should I test?

Accepted Answer

TikTok officially recommends 3-5 creatives per ad group. In practice, the more you test, the faster you find winners.

Here's a practical testing approach:

Week 1: Generate 5 variations of the same product — same script structure, but different hooks and different AI avatars. Run each at $10-15/day.

After 48 hours: Check your hook rate (3-second view rate). Kill anything below 20%. The winner will usually be obvious.

Week 2: Take your winning hook and create 3 more variations — keep the hook, but change the avatar, the script body, or the CTA. This tells you whether it was the hook, the delivery, or the offer that drove results.

Ongoing: TikTok creative fatigue happens fast — typically 7-14 days for a winning ad before performance declines. Have 2-3 new variations ready to replace fatigued creative.

With AI-generated ads, this whole cycle takes about 30 minutes of work per week. With traditional UGC creators, the same testing volume would take months and cost thousands.

Question 9

Can I use AI-generated ads on TikTok? Is it allowed?

Accepted Answer

Yes. TikTok allows AI-generated content in ads. Their ad policies focus on what the ad claims and promotes, not how the video was produced.

A few things to keep in mind:

• TikTok requires that AI-generated content with realistic human likenesses includes a disclosure. Our AI avatars are clearly AI-generated (they don't impersonate real people), which keeps you compliant.

• Don't make false claims — this applies to all ads, AI or not. "This product cured my disease" will get rejected regardless of how the video was made.

• Avoid using AI to impersonate real people, celebrities, or public figures. inReels avatars are synthetic characters, not deepfakes.

• Some regions (EU, certain APAC markets) have stricter AI disclosure requirements. TikTok's ad review process handles most of this automatically.

Bottom line: AI-generated UGC ads are widely used on TikTok. Thousands of brands run them daily. As long as your content follows TikTok's standard ad policies, you're fine.

Question 10

What's the ideal TikTok ad structure for conversions?

Accepted Answer

The highest-converting TikTok ads follow a simple structure:

Seconds 0-3 (Hook): Stop the scroll. Use a pattern interrupt, bold claim, or curiosity gap. This is the only part that matters for getting people to watch. Example: "If you're still spending $300 on UGC videos, listen up."

Seconds 3-10 (Problem/Value): Explain the problem you solve OR the value you deliver. Keep it conversational. One key benefit, not five. Example: "This tool turns any product URL into a video ad in 2 minutes."

Seconds 10-20 (Proof): Show evidence. A quick demo, a result, a before/after. On TikTok, showing beats telling. Example: Show the product in use, show a result screenshot, or show how fast/easy the process is.

Seconds 20-25 (CTA): Tell them what to do. Keep it soft — "Link in bio if you want to try it" works better than "BUY NOW." TikTok users respond to casual CTAs that don't feel like hard sells.

This maps to the PAS framework (Problem → Agitate → Solve), which consistently outperforms other structures on TikTok. For more script structures, see our guide on UGC ad frameworks.

Total ideal length: 15-25 seconds for product ads, up to 30 seconds for demos or explainers.
