I agree with seoman10 in that it is often difficult to get accurate results, especially when a client is out of state and you are trying to replicate what they are seeing. One saving grace is that some tools, like SemRush actually allow you to set where you want to search from ex: if your client is in Little Rock Arkansas & you are located in NYC you can set your rank tracking from Little Rock and it is actually pretty accurate. Nothing is 100%, but we have found this is pretty reliable.
