What is a Contribution Rate?
The contribution rate is a key data point in identifying a likely source of click flooding. Because click flooding involves sending a high volume of clicks – few of which correlate with an install – sources that engage in click flooding have high contributor rates. The contribution rate is calculated by dividing the number of times a given source appeared as a contributor (assisting an install), over the number of times this same source delivered the last-click prior to install.
Only attribution and anti-fraud providers with multi-touch attribution can calculate contribution rates.
