Now, we show one set of statistics for Google and another set aggregating search partner performance. Search partners include AOL, Ask.com, and many other search sites around the web. You can view ad group or campaign performance at a summary level, or broken down by different combinations of Google, our search partners, and our content network. Additionally, separate Google and aggregate search partner statistics will soon be available in the Report Center.
We hope that this additional level of detail will help you better achieve your advertising goals.
