ExactScience uses a credit system to calculate the cost. Each credit costs $0.05 and allows for 30 day refreshes for a single keyword per month. The keyword defaults to device desktop and the United States for location. 

This means if you want to track the same keyword for mobile and desktop, you would use 2 credits. If you want to track the keyword for mobile and desktop, but also search New York, you would use 4 credits.

• 1 credit: keyword + mobile + United States
• 1 credit: keyword + desktop + United States
• 1 credit: keyword + mobile + New York
• 1 credit: keyword + desktop + New York

You can also run a keyword, device, location combination as part of test, e.g. Here are 36 Keywords, I want to pull the SERPs for them. If you only pull them once in a month, then we divide the number of keywords by 30 and charge you for those credits, e.g. 2 credits for 36 keywords for a one time pull.
