The URL builder tool allows you to provide a large number of URLs with measurement parameters (e.g. Google Analytics measurement parameters) all at once. This tool is unique as it checks the output for build-up: the first parameter should start with a question mark, the other parameters should start with an & character. If a hashtag is present in the URL (#), then the tool ensures that the hashtag and the parameter next to the hash character at the end of the URL will be visible. In this way, parameters can be quickly built up for a wide range of URLs without any errors. The URL builder is an excellent tool for transferring large campaigns, and place Google Analytics parameters behind large numbers of URLs.
