GoldKey has a strange bug in their numbers.
When, you see 1, 1, 2, 1, 155, 1, 1,
Most of us are assuming it the spiders or something.
This problem has been part of their system since they started last May.
Just ignore those "one day" high numbers.
Goldkey has a number of advantages and disadvantages.
Domain Sponsor has more of my names but GoldKey gives the best overall revenue results.
I also use NameDrive, Trafficz, Streamic (beta), etc.
