About The Index

The Ad Revenue Index is a single metric served as a baseline to describe the state of the online advertising rates paid out to websites displaying programmatic display ads. Each day, the index calculates a daily index score by sampling across a statistically significant dataset of online ad impressions and consolidates the data into a single number on a 1 to 100 scale.

The index can show how advertising market conditions impact publisher ad earnings. The number 100 on the index represents the highest ad rates recorded by the index.

Digital publishers experience natural fluctuations in their earnings from ads but most have trouble understanding if their changes in revenue are specific to their site, or something affecting all sites.
