AdWords Experiments How Much / How Soon Should You Trust Them?
It’s always easy to jump to conclusions too quickly, but it can even be the case sometimes that Google AdWords actively misleads you.

The AdWords experiment is telling me that “The difference in metrics represents a statistically significant increase.”
This would be very useful to know but for the fact that the experiment is 100% *IDENTICAL* to the control.
Now, Google don’t make a qua-zillion dollars a day from AdWords without being very good at guestimating which ads will get more clicks than others, and I’m sure they get it right more often than not – but please bear these findings in mind before making changes that may adversely affect the performance of your campaigns…
