Understand Movement
Break revenue changes into impressions, eCPM, fill rate, and other drivers instead of staring at one percentage drop.
Personal site / First product
I am building a tool that helps developers understand ad revenue changes.
eCPM Bazaar is an ad data bazaar for small mini game and app teams. Its core value is not another prettier dashboard, but helping developers locate where revenue anomalies come from.

Revenue anomaly diagnosis
Revenue$428-18.4%
eCPM$3.84+2.6%
Fill Rate54.2%-21.8%
Diagnosis Example
US rewarded video revenue fell mainly because fill rate dropped from 78% to 54%, while eCPM stayed stable. Prioritize checking ad source fill, floor settings, and platform status for this placement.

Product Direction
eCPM Bazaar
An ad data bazaar that helps developers understand ad revenue changes. It brings together eCPM, fill rate, placements, countries, and key monetization signals, then turns revenue movement into traceable causes.
Core Function
Ad revenue anomaly diagnosis
When revenue changes, eCPM Bazaar identifies whether the main driver is eCPM, fill rate, impressions, country, placement, or a specific ad platform/source, then suggests where to check first.

Locate Dimensions
Split by country, placement, format, and platform to find the exact area dragging revenue down.
Suggest Checks
Turn anomalies into a practical checklist so developers can inspect the most likely cause first.
Who I Serve
Starting with small teams, not a giant platform.
The target users are mini game and app developers who check ad revenue, eCPM, and fill rate every day. They may not have a data analyst, but they need to know why revenue moved.
About Me
I will validate this with real developer data first.
Before making the product heavy, I want to make the diagnosis useful and accurate. After real data validation, I can decide whether to build a full web tool, API integrations, or a WeChat mini program entry.
