You don't have to be new around here to be confused ;)
I'm confused by this too. Specifically why do this? How does this provide "more relevant results and a high quality experience"?
I''m 'white hat' and I've got two domains that differ greatly in layout, but offer the same products to a searcher.
I too like to split-test the two domains, often with identical ad text, save for one going to myoldsite.com and the other going to mynewersite.com
If I break them out into different adgroups, I need to use the same keywords for my purposes.
I fear a difference in QS with this sudden change and missng out on searches due to the nature of the 'auction'.
I believe I got an overall benefit with QS doing this 'my way', since one domain or the other often contained vital keywords which may have lifted the overall QS for the adgroup.
Frankly, that 'trick' is not something that impacts the 'high quality experience' for users, IMO. Especially with all the junk, often dynamic insertion ads that surround mine. Whether they go to 'old' site or 'new' site, they are getting exactly what they searched for.
I have a lot of adgroups and campaigns where I do this.
AFAIK, there is no feature in the Adwords interface or editor to allow me to search for these.
This presents a rather sudden formidable task for me.
If I recall, when this thread opened, this was something that only agencies were alerted to and even in the discussion here, the exact "rules" were still being debated among us. There was speculation that this only applied to keyword-level destinations which I checked.
And, still at this late date, I have not been notified by Google.
Ironically, the only communications that I got from Adwords today was the rare 'Disapproval' email. For a word in an ad that is now trademarked in a campaign that I paused and deleted all keywords for in mid 2007. I had neglected to pause/delete the ad though if that would have made a difference.
Instead I had to find out only because I opted-in to the adwords.blogspot plethora of emails that I get.
So frankly, I've got a lot of hard decisions to make late on the week-end when I'm tired. I suspect a lot of us do.
And, frankly, I really don't understand why.
Especially when I'm still seeing multiple ads with the same domain showing for the same search due to a Programming 101 test that should be so obvious to Google.
Skaye, you are not alone in wondering what happens to our ads in a day. It's not made clear in the link provided at adwords.blogspot - Adwords should have had a blurb on the interface for weeks.
Am I out of business if I can't perform the superhuman or will they just stop showing one of the ads? The latter I could live with for a little while.
