Spam included in Optimizely results
Last weekend we had a massive wave of spam visitors on our website and conversion rates were dropping from 70% to nearly 24%. The data of this weekend is now not valid anymore, but how could we prevent this in the future?
Sorry to hear about the spam attack! Since this is a unique event specific to this experiment, I think we will need to do some investigation of the raw data. I will open a support ticket for you and we can go from there!
Is there a common User Agent or geoGraphic location in the spam traffic?
A lot of performance monitoring systems (KeyNote, Gomez, Rigor, etc.), use a specific User Agent in their tests so that traffic can be filtered by analytics platforms.
Gomez, Bing search bots, and tools like Rigor typically run from only one geoLocation and could also be excluded (for Bing, you'd have to be willing to exclude all data from Portland Washington).
