URL randomisation for web experiments.

This repository contains all the elements to create a url randomisation for experiments on the web.

Step-by-step procedure:

1. Download and unzip the repository

2. Open 'websites.php'.

3. Follow the directions within the file:

   • Replace the example websites with your own.
   • Balance the weight of the randomisation by duplicating the url. If google.com appears 2 times and apple.com 1 time, then google.com is two times more likely to be the chosen link by the redirection script.
   • Save the file.

4. Upload the two files to your server.

5. Point your participants to https://your-domain.com/random-script.php.

6. Each time you'll visit the above url, you'll be randomly redirected to the websites whose url you wrote in 'websites.php'.
