How Often Does Keyword Tracker Check the Rank of the Keywords I Am Tracking?

Keyword Tracker checks your tracked keywords' ranks once a day, or once an hour for those with the Boost feature activated. Keyword rank can vary by geographical search location, something Helium 10 accounts for in its own algorithms, therefore the data in Keyword Tracker may not always exactly match what you see in your own Amazon searches, which are dependent on a specific geographical location.
