Google Changes to AdWords Reporting A Comprehensive Guide - Manual (Page 10)

Ad distribution
Ad distribution statistics let you see how your campaigns are performing on
Google Display Network and search partner sites.
Before After
In the Report Center, you can see this information by including the “Ad Distribution”
and “Ad Distribution: with search partners” columns.
In the Campaigns tab, you can see the same information by adding the “Network
information” column to your table. Click the “Columns” button in the toolbar
above the table and select the “Network information” checkbox. Alternatively,
click the “Segments” button in the toolbar and select “Network” to see statistics
broken out by network in the table. Segments applied to tables are included as
columns in reports.
First page cost-per-click (CPC)
The first page CPC is an estimate of the bid required to show on the first page of
search results.
Before After
In the Report Center, you can manually include the “Estimated First Page Bid”
column in your keyword reports.
In the Campaigns tab, keywords with the “Below first page bid” status will
automatically show the estimated bid required to place ads on the first page of
search results. However, this metric is no longer available for other keywords.
Position preference columns
If you’ve enabled the position preference feature in a campaign, you can specify
your preferred positions for your keywords on search results pages. It’s important
to keep these preferences in mind when analyzing your keyword statistics, since
they can have a significant impact on the number of impressions for which your
keywords are eligible.
