In-app ads
In-app ads are the fastest way to generate revenue in your app without paid purchases. If you register ads in Apps in Toss, you can start making money from the first day of your app launch without a separate payment feature. This document explains how ad revenue is generated and which ads are best placed where, in an easy-to-understand way.
What are in-app ads?
In-app ads are ads shown to users inside the app screen. They are shown naturally without interrupting the service flow, and generate revenue from that exposure.
Ad revenue is determined in two ways.
How many times they are shown (impressions)
How much you earn each time it is shown (eCPM)
Multiplying these two gives you the estimated revenue.
Estimated revenue = Impressions × eCPM ÷ 1,000
For example, if an ad was shown 100,000 times today and the eCPM is 5,000 won, then 100,000 × 5,000 ÷ 1,000 = 500,000 won.
In-app ad types
It is most effective to use the three ads below together. Using them in combination rather than using only one can greatly increase overall revenue.
Interstitial ads
Ads that appear in full screen at screen transition points.
Feature: forced exposure (users have to see it)
Recommended placement: just before or after screen transitions (e.g., from the results screen to the next step)
Impressions: medium
eCPM: medium
Suitable situations: points where the flow breaks (level complete, booking complete, etc.), moments when users naturally pause
Rewarded ads
Ads that play when the user directly selects 'Watch ad.'
Feature: voluntary viewing, high attention
Recommended placement: when a reward is needed (e.g., extra benefits, continue)
Impressions: low
eCPM: highest
Suitable situations: point grants, additional feature offerings, structures like 'watch an ad to get benefits'
Banner ads
Ads fixed at the top or bottom of the screen and continuously shown.
Feature: always visible (traffic that accumulates automatically)
Recommended placement: main screen, list screen
Impressions: highest
eCPM: lowest
Suitable situations: screens with long usage time, screens visited repeatedly
Benefits of in-app ads
You can choose interstitial, rewarded, and banner ads and show them in places that fit the service flow.
Ad revenue starts from the first day the app is launched, so you can begin monetization right away.
You can use ads as a trigger to encourage users to keep using the service, increasing retention.
In game services, 'continue after watching an ad' can let users keep playing stages they were challenging, naturally encouraging reuse.
Set up in the console
1. Register business information
To integrate in-app ads, you must first register your business information. Your business information must be registered before you can proceed to the next steps: agreeing to the terms and entering settlement information. For instructions on how to register, Guideplease refer to it.
2. Enter settlement information
When you integrate in-app ads, ad revenue is generated. To receive settlement for your revenue, register settlement informationYou need to. Enter your settlement information in the 'Info' tab of the workspace, then request review. Review takes an average of 2 to 3 business days.
Please be sure to check
Please enter the account holder name exactly as it appears on the copy of the bankbook, without any differences in even a single letter. If it is entered differently, settlement may be delayed.
3. Create an ad group
Apps in Toss in-app ads follow Google AdMob ad policies. If you do not comply with the policies, ads may be limited or suspended.
3-1. Ad group name
It is easier to manage if you include both the ad type and placement. Since you will manage multiple ad groups during operation, please give them names that will be immediately understandable later.
e.g.) Main_InterstitialAd, GameEnd_RewardedAd
3-2. Ad type
Banner
Ads that always float at the top or bottom of the screen.
As you use the app, exposures accumulate automatically, creating steady revenue.
However, once users become familiar with it, they tend to ignore it, so the unit price is the lowest.
Interstitial
Ads that appear in full screen at screen transition points.
Because users cannot ignore them, the unit price is higher than banners.
It feels natural when inserted at moments when the flow is interrupted, such as level clears or content transitions.
Rewarded
Ads that start only when the user directly taps 'Watch ad.'
Because users focus until the end to receive the reward, the unit price is the highest.
It is effective when connected to moments that benefit the user, such as granting points or items.
3-3. Reward
Fill in only when Rewarded ads are selected. Please enter the exact name and quantity of the reward the user actually receives. Since this is displayed on the user's screen, it is better to use the same terms as those used in the service.
e.g.) Reward unit in service: chance / quantity and amount: 1
3-4. Mediation
Mediation is a technology that connects multiple ad networks and automatically selects in real time the ad with the highest revenue. The ad network that matches the category registered in 'App info' will be set automatically. You can change it to another category, but the changed content is not reflected in App info and is applied only when creating an ad group.
After registering, you can check the ad group ID on the detail screen.
It may take up to 2 hours for the ad group ID to be registered with Google.
Please develop using the ad group ID provided after creating the ad group.
Ad operation policy
Toss Ads SSP policy
Please make sure to follow the policies below. If you violate them, ad exposure may be restricted.
Even if it is not written in this policy, Actions that artificially induce ad exposure, clicks, or performance, or mislead users, may be considered policy violations.
If the service is terminated due to a policy violation, all partners must follow the service termination policy.
Degraded UI/UX quality
Actions that blur the distinction between ads and content, induce ad consumption or clicks unrelated to the user's intent, or configure the UI to interfere with normal service use
Disguising ads as "Recommended services," "Financial tips," etc.
Changing the color or font of ad units outside the Toss Ads guide
Arbitrarily modifying the ad title, label, CTA text, and design
A structure that places ads adjacent to user interaction elements (buttons, gameplay areas, etc.) so that unintended clicks occur
When two or more ads of the same format are placed on the same screen
A dead-end structure that makes it difficult for users to close the screen normally or move to the previous screen
A structure that makes it difficult for users to distinguish between the functions of ads and service CTAs
A structure that makes it difficult to recognize or access CTAs needed for normal use of the service
Ads must always retain the "Ad" label

UI/UX configurations that artificially induce ad performance or degrade the user experience are prohibited
Ad call behavior tampering
Actions that change or bypass the SDK's default event flow or ad call method

If the Back button is blocked or abnormally controlled, preventing the user from closing the screen normally or moving to the previous screen
Do not tamper with the SDK's default event (Click / Impression) structure
No external API calls outside the SDK
Abnormal traffic and performance manipulation
Actions that distort traffic and ad performance by automated or artificial means
Periodically refresh the ad area
Activities that artificially generate performance (clicks, impressions, etc.)
If abnormal patterns based on traffic quality are identified, ad restrictions, sanctions, and settlement holds may be applied
Reward/engagement-based click inducement
Providing rewards or benefits at the same time as an ad click
"Provide a reward immediately after clicking the ad"
"Provide points when you click the ad"
Do not directly link ad consumption to rewards
Do not link reward-related phrases or events to clicks
Ad hiding or overlap
Actions that intentionally hide ads or obscure them with other UI elements so that users cannot clearly recognize the presence of the ad
• Transparent ad
• Insert the ad DOM behind another card UI
• The ad must have a clearly verifiable visible state
UX / Product Principle operating principles
Ads must also follow Toss's UX principles.
Toss Principle
Application criteria
example
Simplicity
Ads must be clear and understandable without additional explanation
"View now", "Watch ad" etc. clear CTA
Clear Action
Users should be able to predict what action will occur after clicking an ad
Provide a notice when moving externally
No Deception (UX Red Rule)
Ads must not appear in unexpected moments, forms, or positions, or mislead users.
When ads are disguised as content
Value First
Ads must not interfere with the customer's service goals.
Do not insert ads during payment/account opening flows
Usage restrictions and sanctions
If Apps in Toss ad placements or services violate this policy, sanctions may be imposed.
Restriction procedure
In principle, restrictions are applied step by step according to the accumulation of violations. Depending on the type or severity of the violation, even a single violation may result in an immediate 30-day suspension or a permanent suspension.
※ Violations identified at the same time are counted as one violation regardless of the number of violation slots. If violations are identified separately later, the violation count accumulates.
Handling of unjust gains
Revenue generated through policy violations, invalid traffic, or other fraudulent means may be considered unjust gains.
If unjust gains are identified, payment of that amount may be withheld or rejected. Amounts already paid may also be recovered.
Appeals process
If you receive a notice of usage restriction, you can file an appeal within 30 days.
Appeal materials can be submitted through Channel Talk.
The submitted materials will be reviewed according to internal standards, and additional materials may be requested if necessary.
Review may take about one week on business days.
Appeals are reviewed with a focus on whether the sanction was appropriate. The sanction will not be lifted simply because the violation has been corrected or a recurrence prevention plan has been submitted.
The sanction may be lifted if the submitted materials do not substantiate the violation that was the basis for the sanction, or if it is confirmed that there was a clear error in the sanction decision.
Repeated or serious violations may result in a permanent restriction on service use.
Integrate development
Please be careful not to expose ads to users too frequently.
When testing in-app ads, you must use the test ID. Using a production ID may result in sanctions.
While the ad is playing, please pause the app sound temporarily and resume it automatically when the ad ends.
