The old data is there though (thankfully) and shows when you do a "combined" report. You just don't get the extra detail of the new link unit report.
At any rate, this is a nice addition to the report options. Thanks Google.
I don't understand how this can be. Every page (except blog, which has no link units) has an Ad Unit and a Link Unit, so the page impressions should be roughly equal. What this report tells me is that the Ad Units are displaying only about 10% of the time that somebody view my pages? Every time I check, both the Ad Unit and Link Unit are there. It seems to me that page impressions for both types should be roughly the same.
Also, the CTR of the Link Units are pathetic, as I always suspected. On the other hand, the CTR of the Ad Units are incredible. The same thing applies to the eCPM's.
So, am I reading this wrong or is it really possible that Ad Units are only rarely displayed on my pages? Again, every time I look the Ad Units are there. BTW, about 75% of my traffic is from the US and the site is US based and hosted.
