CPC bucket and heatmap script

This free script helps you identify when higher CPCs reduce account or campaign profitability by grouping click costs by hour and day and visualizing them in heatmaps.

It analyzes CPCs per hour and weekday, placing the data into CPC buckets. You can set a maximum CPC for campaigns and use heatmaps and cumulative graphs to understand which CPC levels are profitable.

It is an analysis tool: setting a lower maximum CPC can limit lead or purchase volume, so set thresholds after reviewing performance.
