Don't let your budget leak in Telegram Mini App Ads. Use native TMA formats on OnClickA to learn 8 proven methods to deal with iGaming, finance, and rewarded offers.
Running iGaming, Finance, or Rewarded game offers? Here’s how to avoid the most common budget leaks in Telegram Mini Apps.
Telegram Mini Apps are a major growth channel in 2025, yet many advertisers still waste budget because their setup and strategy don't match. At OnClickA, we analyzed hundreds of campaigns to find where results usually drop. These 8 fixes will help you grow and protect your budget using native TMA formats.
- Interstitial - high visibility and clicks.
- Rewarded Posts & Videos - motivated audience and engagement.
Let’s align your setup with the Telegram Mini App mechanics.
1. Choose the format by strategy, not habit
Many advertisers choose a familiar format instead of matching it to their campaign goal. In OnClickA, your format is your strategy that determines the pricing model.
Tg-Interstitial. CPC only
Drive traffic to your app and pay only for clicks.
Rewarded Videos. CPM & CPC
Engage users with a promotional video in exchange for in-app bonuses.
Rewarded Posts. CPM & CPC
Deliver an engaging text post that users view to earn rewards.
The Pro Fix: Go with CPC Interstitials to get clicks or start with Rewarded ads - they are your safe zone for getting a motivated audience.
2. Align the first screen with ad promises
An ad promises "Instant win" or "Quick quiz", but the first screen users land on is a generic onboarding flow. When expectations and reality don't match, users feel misled and close the app, dropping your engagement metrics.
Continuity
Let the first screen immediately restate the ad’s promise. Ads and apps should belong in the same world.
Minimalism
Make a simple offer. Use one call-to-action. Keep the text concise.
Testing
Launch campaigns leading to different first screens. Select the most engaging one.
The Pro Fix: The first screen needs to fulfill the ad's promise in the first 1-3 seconds. Promised a spin? Show the wheel. Promised a quick quiz? Start the first question. Promised a bonus? Let users claim it right away.
3. Make your offer Telegram-native
What works on the web often underperforms in Telegram. Due to the platform's social and Web3-focused culture, users respond better to soft, interactive experiences. Aggressive, direct offers tend to lose attention before users engage.
Native Verticals
Focus on offers that naturally fit the Mini App ecosystem: iGaming, Finance, Crypto, and Rewarded Games.
Gamification
Wrap your offer in interaction. Simple gameplay keeps users engaged.
Soft Entry
Lower the entry barrier. Add a free and simple first step before asking for a complex action.
The Pro Fix: Adapt your offer to the platform. If your product is complex, build a bridge - a free step inside the Mini App, like a wheel spin or a short quiz, that pulls users into the flow.
4. Adapt to Telegram visual style
Telegram users scroll faster than web users. To bypass ad blindness, your ad should look like it belongs in the messenger. To capture attention, keep it dynamic, use a short, motivating message.
Telegram look & feel
Use rounded corners, emojis, a concise CTA, and Roboto or San Francisco as fonts.
Premade templates
Use templates to ensure your ad matches the TMA environment.
OnClickA ad skins
Select these templates directly in the OnClickA dashboard. They are ready for Interstitial ads.
The Pro Fix: Check both your creatives and your Mini App’s first screen. They should look like a seamless continuation of Telegram - and of each other. To make sure your ad looks native, try choosing ad skins in OnClickA.
5. Start with broader targets
Telegram usage patterns vary by region and user habits. Start with broad parameters to let the data show you where the profit is.
Essential Targeting
Focus on main parameters: GEO and languages.
Staying broad
Launch wide and narrow your targets only if needed.
Interests
Use Interests - specialized Telegram targets to reach users with a crypto wallet.
The Pro Fix: Use main targets to maintain stable volume, but keep your settings as broad as possible at the start. Reach out to your Onclicka manager to find the right balance between reach and precision.
6. Test diverse ad formats
Many advertisers stick to one format and ignore the rest. In OnClickA, different TMA formats solve different tasks. Testing and combining them delivers better results than relying on a single option.
Understanding format roles
Interstitials drive high visibility. Rewarded Ads deliver a more motivated audience.
Testing formats in parallel
Make creatives for at least two formats. Test them at the same time.
Combine by goal
Choose and combine formats based on your campaign goal rather than habit.
The Pro Fix: Test several ad formats and try combining them. For example, use Interstitials to build awareness and Rewarded Ads to drive conversions.
7. Wait for data
Mini Apps provide fast feedback. However, the more data you collect, the more accurate your conclusions will be.
Data
Initial CTR and conversion rates can be volatile. Give the campaign time to collect more data on user behavior.
Stats
Edit campaigns after you know the statistics.
Numbers
Base your decisions on metrics, not early fluctuations.
The Pro Fix: Give your campaign time to settle. The best-performing campaigns are usually the ones that were allowed to learn the audience before being optimized.
Your TMA Checklist
Telegram Mini Apps are evolving fast. Stay native, stay data-driven, and keep testing.
Do this last check before you start your next campaign:
- First Screen - Promises fulfilled.
- Creatives - Telegram-native.
- Targets - Wide enough.
- Format - Matches your strategy.
OnClickA managers are ready to help you with these steps to launch your TMA campaign.
