I want to share something Iíve experienced few days ago, first time in a very clear way.
I had two ad groups, where I had keywords related to each other, but different enough to be divided into two (ad groups).
After a long time in the premium yellow area, ads from group 1 went out of it (second position) and QS went to OK, minimum bid to 10 cents.
Group 2 got into similar situation (in and out).
I remembered I had an ad in Group 2 under pause, one that performed well, but I wanted to change it (didnít like it).
So, I paused the rest and set ďuglyĒ one to active. All was right, QS great, minimum bid 5 cents.
In Group 1 (that was on a side all that time) I created a new ad that was in wording similar to the good performing one from Group 2, and BINGO, in 2 minutes it was in yellow area, QS Great, minimum bid, 5 cents.
This was the clearest and quickest QS change I ever saw in AdWords so far, which resulted in regaining the premium spot in paid search results with no change in maximum bid, but by changing ad text only.
