Changing an image when the experiment is running
I have a banner ad that is only included in the variation page. Within the banner, there's one image (logo) that I must change. I'm not sure, however, if changing the image will pause or cause any intruption in my experiment?
@lfapps - You can modify your experiment at any time. This will not pause your experiment or reset any of the conversion goals.
As a general consensus, you should be certain (judgement call) that the change you are making is immaterial to the experiment itself (for example, if your experiment is testing a "Product Image" vs a "Person Using the Product Image" and they give you a slightly adjusted People Image to use, you would be OK). If the new image is drastically different, then you may want to re-set the experiment anyway.
Here is an insightful article that came across my desk today about how image choices can affect user engagement - Netflix tested *lots* of variations of whch images they serve up for their shows and reported some interesting results:
