1. What creative sizes are supported, and which ones are required?

For video creatives, the supported sizes include 1280x720, 720x1280, 1920x1080, or 1080x1920 — any one of these is acceptable.

For image creatives, the required sizes are 512x512, 1200x627, or 1200x628.

To maximize traffic coverage, it’s strongly recommended to also include the following image sizes: 720x1280, 1024x768, 768x1024, 320x50, and 728x90.

2. How long does it take for creatives to be approved?

Creatives are usually approved within 24 hours. Review time will be increased on holidays and weekends. Dynamic interactive creatives (IEC and Playable) require technical manual testing, and creative review usually takes 1-2 working days. If the review is not completed for a long time, you can ask for help via email.

3. Why might a creative get rejected even after it was initially approved?

In addition to reviewing newly submitted offers and creatives, our system also performs ongoing reviews of active offers. If any content is later found to violate our creative review policies, it may be rejected or taken down accordingly.

4. What are the common reasons for creative rejection?

The following creatives in your account (Username: xxx) have been rejected due to non-compliance with the creative requirements. Please revise the creatives accordingly.

Reject Reasons are as follows:

[No Pornographic Information]: Contents with sexual implications are prohibited, e.g, Excessive body exposure, obscene gestures.
[No Political Information]: Contents involving the state, state agencies, ethnicity, and race, harming the interests of the state, are prohibited.
[No Violence and Terrorism]: Contents that are negative, ugly, horrible, bloody, and violent are prohibited
[No Irrelevant Third-party Information]: Creatives can not contain irrelevant third-party information,e.g., IOS campaigns creatives are prohibited from containing the icon of Google Play and vice versa.
[Real-Money Games]: The creatives must include the following disclaimer statement. All text must be displayed and fully readable, covering no less than 20% of the creative frame. The disclaimer language must be aligned with the creatives. This game involves an element of financial risk and may be addictive. Please play responsibly and at your own risk.]
[Sweepstakes games]: The creatives must include the following disclaimer statement. All text must be displayed and fully readable. In video or HTML5 creatives, the text must be displayed at all times.

5. Why does the creative stay in the "Pending" status for a long time?

The creative may involve casino, gambling, finance, cryptocurrency, real money, and other sensitive content. It is necessary to sign the sensitive category agreement and provide the license issued by the regional regulatory agency before it can pass the review.
The creative review may be delayed during the holidays. If the review cannot get approval for a long time, you could email the specific campaign/offer name and creative name to ask for the reason.

6. If I’m only running video creatives, why do I still need to upload a 1200x627 or 1200x628 image? How is it displayed?

On Mintegral video ad placements, a landing page appears after the video finishes playing. The 1200x627 or 1200x628 image will be displayed on that landing page.

7. What should I do if my creatives aren’t scaling?

Here are some optimization suggestions for underperforming creatives:

Check targeting settings and bids/goals

Please verify whether all offers are not scaling. If so, check whether the basic targeting settings are reasonable or whether the CPI/TCPE bid is too low or the ROAS goal is too high to win impressions.
Avoid uploading too many new creatives at once

We recommend uploading 3–5 sets of video creatives (both landscape and portrait), 3–5 image creatives (1200x627 or 1200x628 and 512x512 are required sizes), and 1–2 playable creatives per batch. Avoid uploading new creatives multiple times within 3 days, as this may disrupt the algorithm’s learning and affect performance.
Try re-uploading creatives

For creatives that have been approved but haven’t scaled after 5–7 days, consider deleting and re-uploading them to reactivate data collection and performance.
Don’t refresh creatives too frequently

As a general rule, we recommend updating creatives every 2 weeks.

9. How do I view my creative's reporting and analytics data?

To view performance data by creative, go to the “Creative Monitor” report in the Mintegral reporting dashboard.

- Standard: Only video or image creatives are shown.

To analyze performance by creative, we suggest selecting the following dimensions:

If you want to check the performance of playable creatives:
- Check “Creative ID”, “Creative Name", “Endcard ID”, “Endcard Name”, and “Ad Output Type”

10. What Are the Best Creative Optimization Strategies?

During the Initial Launch Period (First 3 Weeks)
- Prepare creatives in advance: Upload diverse creatives according to Mintegral’s creative dimension specs. This helps cover more inventory and gain more traffic.
- Group creatives strategically: Classify by language, theme, or duration. If there’s no specific requirement, we suggest one creative group that includes:
  - 3–5 sets of videos (both landscape & portrait)
  - 3–5 image creatives (1200x627/628 and 512x512 are required)
  - 1–2 playable creatives
- Avoid over-uploading: Don’t upload too many creatives at once, and avoid frequent uploads within 3 days. Once the offer stabilizes, iterate gradually.
- Prioritize playables: If you have playable creatives, prepare and launch them early for better performance.
During the Stable Period (After 3 Weeks)
- Iterate creative groups regularly: Refresh creatives every 2–4 weeks. Keep high-performing assets and remove those that don’t scale to improve efficiency.
- Reactivate old creatives: For creatives that were approved but haven’t scaled after 5–7 days, try deleting and re-uploading them to re-trigger performance.
