Why do test pages look different with each refresh?
Each time I click refresh, the website looks a bit different.
I'm not making any edits and these changes to the page are happening on their own.
What is going on?
This is the test page.
Do you notice the ad moves around? See 3 screenshots below.
those are simply different ads, aren't they?
Probably the page runs an adserver which "rotates" the ads.
What has that do to with Optimizely?
