A: Good question Zam!

Think of Units as an individual search. So if you're creating a Reveal the parameters you select will designate how many Reveal units will be used.

Here's an example:

You're running a Reveal for 5 Keywords, in 2 Cities, Every 2 hours, for 7 Days.

5 x 2 x 12 x 7 = 840 units

So in this example, to run the reveal for this period it would require 840 units to get all the data.
