SerpWatch supports both Desktop and Mobile keyword rank tracking.
Keep in mind that each device is a different index request.
This means that if you want to track 1 keyword on both Desktop and Mobile, Google needs to check it as 2 separate keywords to give accurate results.
So if you are tracking the same keyword on both devices, we count this as 2 keyword checks.
To learn more about how we calculate keyword check usage, refer to our Pricing Model guide.
