Telegram Mini App onboarding: turn first opens into active users
Design Telegram Mini App onboarding that keeps users: instant value, Telegram login, progressive tutorials, first rewards, bot opt-in and measuring activation — so paid and organic users stay and earn.

Quick answer
Good Telegram Mini App onboarding delivers the core value in the first 30 seconds, uses Telegram identity instead of sign-up forms, teaches by doing rather than with long tutorials, gives an early reward, and asks users to start your bot so you can bring them back. Define one activation event — finishing a level, completing a profile, making a first action — and measure what share of new users reach it on day 0. Better activation makes every acquired user worth more, including ad revenue from Reward, Interstitial and Task ad blocks.
Key takeaways
- Show value within 30 seconds of the first open.
- Use Telegram identity — no sign-up forms.
- Teach through action, one step at a time.
- Measure an activation event and improve it continuously.
Why the first session decides everything
Most users who leave a Mini App do so in the first session. Every second of loading, every form and every confusing screen loses people you may have paid to acquire.
The onboarding checklist
- Fast load: keep the first screen light and cache assets.
- Instant identity from Telegram launch data.
- A one-screen explanation of the value.
- An interactive first action instead of a text tutorial.
- An early win or reward.
Bringing users back
- Ask users to start your bot for reminders and rewards.
- Introduce daily rewards or streaks after the first session.
- Invite friends via Telegram sharing after a positive moment.
Onboarding and monetization
Avoid showing interstitials during onboarding. Introduce opt-in rewarded ads after users understand the app, and use frequency caps so ads add revenue without hurting activation.

Metric definitions and formulas
- CPM
- Cost per mille: what an advertiser pays for 1,000 ad impressions.
CPM = (Ad spend ÷ Impressions) × 1,000 - CPC
- Cost per click: average price an advertiser pays for one click.
CPC = Ad spend ÷ Clicks - CTR
- Click-through rate: the share of impressions that produced a click.
CTR = (Clicks ÷ Impressions) × 100% - eCPM
- Effective CPM: what a publisher earns per 1,000 impressions, whatever the pricing model.
eCPM = (Publisher earnings ÷ Impressions) × 1,000 - Fill rate
- The share of ad requests that returned an ad.
Fill rate = (Filled ad requests ÷ Total ad requests) × 100%

Worked example
Hypothetical example — not real Adsun data
An advertiser tests $250 across 3 countries at a $0.05 CPC = 5,000 clicks; 38% reach the page = 1,900 visitors; 6% leave a lead = 114 leads at ≈ $2.19 each. A publisher with 8,000 daily users showing 1.5 ads each = 12,000 impressions; at a $1.20 eCPM that is about $14 a day. Replace every figure with your own data.
Adsun measurement methodology
Adsun counts an impression when an ad is rendered in a publisher block, a click when the user opens the ad destination, and a reward only after the server-to-server Reward URL confirms completion. Debug-mode traffic is excluded from billing and reports. Metrics are shown per platform, block and country in the partner and advertiser dashboards. Adsun does not publish aggregate network benchmarks in this guide; any number below marked “Hypothetical” is illustrative only. See the SDK documentation for integration details.

Frequently asked questions
What is Mini App onboarding?
The first-session experience that takes a new user from opening the Mini App to understanding and using its core value.
Should a Mini App have a tutorial?
Keep it interactive and short; teach one action at a time while the user plays or uses the app.
Do users need to register in a Mini App?
Usually not — Telegram launch data identifies users, so you can skip sign-up forms.
When should I show ads to new users?
After onboarding. Opt-in rewarded ads work best once users understand the value of the reward.
What is an activation event?
The first meaningful action that predicts a user will return, such as finishing a level or completing a profile.
How do I get users to start my bot?
Offer a clear benefit — reward reminders, event alerts or a bonus — and ask at a positive moment.
How does onboarding affect ad revenue?
More activated users means more sessions and more ad impressions per user, which raises lifetime earnings.
