A system and method to efficiently and randomly place users into a test group associated with a test running on a website being hosted on a server is disclosed. When a user first accesses the website, a random value is transmitted to the user in such a manner that the random value is stored in a computer-readable memory local to the user. Each subsequent time the user accesses the website, the random value is returned to the server from the user. The server may then place the user into a test group for a test to which the user will be exposed on the website based upon the result of an operation that includes the random value received from the user and a unique test value previously associated with the test. |
