Is anyone known with this? because I don't want to have other ads in the same group being affected with the QS of another new ad that is added.
I added two ad texts to a well established campaign and the next day I saw 10% of the keywords go inactive.
I immediately paused those ads and two days later inactives turned active.
I wish G would add one more level of complexity to their QS whereby they match keywords to optimum ad text. Assuming you have a few ad texts then it is obvious that some keywords will have a slighter better QS with one ad text vs another. We currently have very little indication of which specific ad text scores best with which specific keyword (without a lotta work).
ps. then again, the whole QS thing blows anyway.
So adding an extra AD affects the whole QS of the ADgroup.

btw I used the same adtext but another destination and display url, so it really devalued the other new destination page.
