Overview

Comet's assistant handles maths instantly, letting you get the answer you need on the fly to keep your head down on important work.

In this example, media planners and buyers constantly perform quick calculations, converting between CPM, impressions, and total spend. Sometimes this can slow down negotiations and planning sessions when done manually.

Comet can let you input a buy value and CPM to get projected viewership, or reverse-engineer a budget from an impression goal. It can also show its work, making it easy to verify and share the calculation with stakeholders.

Key output

Tips

  • Ask Comet to reverse the calculation: Try 'how much budget do I need to reach 75 million impressions at a $28 CPM?' to quickly work in any direction during negotiations
  • Run multiple scenarios at once: Ask for a table showing viewership at CPMs of $20, $23.80, $26, and $30 for the same budget to quickly compare options
  • Add context for more useful output: Include details like 'this is a connected TV buy' and ask Comet to 'note what an efficient CPM benchmark looks like for this channel' to get strategic context alongside the maths
