2.1 Impression Frequency Report

(1) Content Overview

The usage duration report supports impression frequency data statistics in five dimensions: date, app, placement, area, and channel. It supports viewing the time change trend of imp. frequency and the distribution ratio between different frequencies. The detailed data section also supports viewing the daily frequency details and supports data report export.

The filter items and indicators involved in the report are as follows:

Filter Items	Description
Date	The time period when the data was generated. Note: You can select a date of up to 60 days each time.
App	App created in TopOn. >>More
Placement	Placement created on Taku. >>More
Area	User's country/area
Channel	Developers can pass the channel field to TopOn to distinguish the data from different source channels of users. >>How to pass channel fields through custom rules?

Data Metric	Description
Impression frequency	The proportion of device users who have watched N ads in this placement among the active users of the day. Calculation formula: (device users who have watched N ads/DAU)*100%.
n times	The number of active users who have watched n ads in this placement
Device Num	The number of all devices in a section. For example, the eCPM range of [0,1) corresponds to the number of impressions that are the number of unique devices displayed by the ad with an eCPM between 0 and 1.
Device Num Rate	Formula = Number of devices in the corresponding range / Sum of the number of devices in all ranges * 100%
Impression	The number of all impressions for a period. For example, if the eCPM range of [0,1) corresponds to the cumulative number of impressions of ads with an eCPM between 0 and 1.
Impression Rate	Formula = Number of impressions in the corresponding interval / Total number of impressions under the current filter conditions × 100%
Est. Revenue	The sum of the estimated revenue for all impressions in a range.
Estimated Revenue Rate	Formula = Estimated revenue of the corresponding range / Total estimated revenue under the current filter condition * 100%
eCPM	Estimated revenue/Impression *100%

2.2 User Value Report

(1) Content Overview

The user value report allows you to view the eCPM data displayed in the dimensions of date, app, placement, area, and channel. It supports displaying the number of impressions and corresponding revenue of different eCPM ranges, quickly determining which eCPM range has the most impressions for developers, and helping to determine how to configure the interval data of the user value segment by estimating the Cumulative ratio of Est. Revenue.

The filter items and indicators involved in the report are as follows:

Filter Items	Description
Date	The time period when the data was generated. Note: You can select a maximum of 60 days each time.
App	Apps created on Taku. >>More
Placement	Placement created on Taku. >>More
Area	User's country/area
Channel	Developers can pass channel fields to Taku to distinguish data from different source channels of users. >>How to pass channel fields through custom rules?
eCPM range	This filter does not affect the data results of the current page, and the data displayed on the current page is only affected by other filters. If you select a different eCPM range, it will only affect the interval to which the data in the graphs and tables is aggregated. For example, if you set the eCPM range to [0-50], the maximum eCPM range of graphs and tables will be displayed to 50, and the data above 50 eCPM will be aggregated in the range [50, 50+]. Tip: If you find that most of your data is concentrated in the largest eCPM range, select a larger eCPM range.

Data Metric	Description
Impression	The number of all impressions for a period. For example, if the eCPM range of [0,1) corresponds to the cumulative number of impressions of ads with an eCPM between 0 and 1.
Impression Rate	Formula = Number of impressions in the corresponding interval / Total number of impressions under the current filter conditions × 100%
Device Num	The number of all devices in a section. For example, the eCPM range of [0,1) corresponds to the number of impressions that are the number of unique devices displayed by the ad with an eCPM between 0 and 1.
Device Num Rate	Formula = Number of devices in the corresponding range / Sum of the number of devices in all ranges * 100%
Est. Revenue	The sum of the estimated revenue for all impressions in a range.
Est. Revenue Rate	Formula = Estimated revenue of the corresponding range / Total estimated revenue under the current filter condition * 100%
Cumulative ratio of Est. Revenue	The cumulative estimated revenue from 0 to the current eCPM range as a percentage of the total estimated revenue. Formula: Sum of estimated revenues for eCPM ranges from 0 to the current range/Total estimated revenues for all filtered items in the current filter * 100%. For example, the cumulative ratio of estimated revenue corresponding to [4,5) needs to be summed for the estimated revenue ratio of [0,1], [1,2], [2,3), [3,4), and [4,5].

Example:

As shown in the figure below, the current selection condition is eCPM range = 0-20, and according to the data, it can be seen that 2 ads in the total ad impressions of this ad slot have eCPMs in the [0,1) range, accounting for 22.22% of all impressions. The estimated revenue of eCPM<20 accounts for 44.89%, and you can choose a larger eCPM range to view data in more intervals.
