Today I discoverd that it’s possible to export preview urls in Optimizely without even starting the test!

You can do this by following these 3 steps:

1. Open a test in Optimizely

That should be easy, you can do it!

2. Open the preview

3. Change the url

When the preview link opens copy the url and change the optimizely_show_preview querystring parameter from from true to false.

So from:
https://www.your-page-under-test.com/?optimizely_show_preview=true&optimizely_token=d7a7ad7ffggfda790bb1c3fb57570169a5bb&optimizely_x3029150007=1

To:
https://www.your-page-under-test.com/?optimizely_show_preview=false&optimizely_token=d7a7ad7ffggfda790bb1c3fb57570169a5bb&optimizely_x3029150007=1

4. Change variant (bonus)

The number in the end of the url refers to the variation you are previewing. Changing this number thus allows you to quickly switch between two variants. So let’s say we have this url to preview variant #1:

https://www.your-page-under-test.com/?optimizely_show_preview=true&optimizely_token=d7a7ad7ffggfda790bb1c3fb57570169a5bb&optimizely_x3029150007=1
  

We only need to replace the 1 with a 2 to preview variant #2:

https://www.your-page-under-test.com/?optimizely_show_preview=true&optimizely_token=d7a7ad7ffggfda790bb1c3fb57570169a5bb&optimizely_x3029150007=2
  

I hope this helps! Good luck!
